Hey, I was wondering if anyone could confirm or tell me whether the Edge Evolution CTS has makes it so my truck has a turbo brake when it is in the tow mode? I have ready threads where people say it will do it and threads where people say it will not do it...:p:

Thanks!!

Depends who you ask. Edge service rep (don't remember the name) says no. Holton at Aligator Performance says yes in every tune level. Holton also called EDGE and talked to a tech to verify and was told "yes, slight turbo braking in every level". Edge tech also said that there will be updated tunes for the LLY soon and, that the turbo brake will be enhanced.

Also, do not tow over 8K in level 2 (towing). Use level 1 or stock according to edge............. I just towed 7K - 8K through the pass in the smokey mountains on tuesday and wednsday. Ran level 1 and level 2. I found level 1 seemed to drive better, hold lower EGT's. It also seemed to get better fuel ecconomy, but that is questionable due to other variables. Turbo and tranny braking seemed to be about the same in either level from what I could tell.

Thanks for the information!!! Nice to know

I wish I knew the time frame for the LLY update myself. Holton was told that they are working on tuning for another engine at this time. The LLY is on the to do list. My guess would be 6 months to a year.

Next answer...
I said that I towed in level 2 & 1 a couple days ago. That was wrong. I towed in level 2 a few weeks ago and did not like it at all. Coming through the Smokey Mountains I used level 1 and Stock. However my stock program is not stock, but rather an unknown program that was in the truck when I bought it. That said, I did like level 1 better and to be fair, I would have to say I didn't feel much of a differance in exhaust braking in level 1,2, or stock. I did feel that more would be better especialy since I plan on getting a heavier trailer in the next few months. Also I would like to see EDGE come out with a heavy tow, and a light tow program. Overall the exhaust braking was pretty good for the load I was towing in level 1.

Another thing I did notice. In the stock program it seemed that the exhaust brake/down shift happened a bit quicker than in level 1. Not sure why that is. But a a little quicker response would be nice in some areas, maybe worse in other conditions. The differance between the programs was about 1 second or so.

Hope that helps.

Yeah thanks for the information! Very Much appreciated! I am looking to get one in the next few months and just making sure its the right thing to do and I wont be mis-led or disappointed. Sounds good though,
thanks!:D

Anyone else feel like chiming in, go ahead!

The programmer would only load if you had a stock tune on the truck so you have a stock tune on your truck.

That's exactly what I thought also.
I had a problem installing the Evo. I called Edge and they told me to hook up the Evo to my computer. I down loaded (what I was told was) a new stock file. Afterwards I was able to install the Evo without any problems.

What I found out a few weeks later was that Edge sent a update to my Evo (via internet connection) that told it to accept the trucks programming as stock. Which really makes sense if you think about it. Although this could create some problems if the original program had more files that were modified than the Evo. Edge did reccomend getting the ECM re-flashed with the latest GM programming, which I haven't done yet.

So as i understand it, when I set my Evo back to stock (as of now) it simply reloads the original program back in. I do see evedence of this as well. When I bought the truck is was throwing occasional 2 codes and triggering the CEL. I had the codes checked and it didn't seem to be causing any problems. When I run the Evo on any level other than stock it throws no codes. When I return to stock programming I occasionally get those same 2 codes poping up along with the CEL. So it seems that the original programming is still there as a stock program.

I'n still having some issues with the truck and plan on getting the ECM re-flashed in the next few days...

If edge got involved well that different. I still think they sent you a stock tune.

I have Edge CST installed on my LLY. I have ran it in level 1,2, and level( 3 very little). The Turbo brake doesn't seem to work any different then stock in level 1 or 3. In level two it works very well if you put the transmission in the tow mode. (It seems to only work if the converter is locked.) The torque converter locks in 3 4 and 5 gear in the tow mode. I tow a 14000 pound fithe wheel and it works very well.

A couple questions:

1) Have you towed in level 1 under the same conditions as level 2?
2) Did you know Edge reccomends using level 1 or stock for Towing anything over 8000#? (I was a little upset when I found that out)
3) What kind of MPG are you seeing while towing on level ground? (I'm seeing 9.6 in high wind, to 11.5 on the flat areas @ 65 mph, Hand calculated)

See here I have 3 differant stories on the turbo brake programs with the EVO. Not wanting to start something here, just don't know what to belive or who to trust. Just for the record I have the CS not the CTS. I was assured that the programing was the same, and only the displays were differant. Starting to doubt that a little too.
1) Turbo brakes in level 2 with tow/haul.
2) Edge service rep. "No turbo brakes on the 04.5 -05 LLY
3) Edge tech (through Holton @ Aligator). "Some light turbo braking on every level".
:confused::confused::confused:

I tow heavy loads just watch you temp's, EGT's, ect. My pickup is 2005 LLY. If you watch your vane position on the turbo you will see that even the stock tunes close's the vanes somewhat 60 to 70 percent while decelerating. But the effect isn't near as dramatict as 98 percent vane closer as in level 2 in the tow haul mode. I purchased my unit thru alligator performance. I would go with EFI live next time. But the edge will de fuel back to stock setting. when temps are exceeded. I am happy getting 8 to 10 MPG climbing hills wind ect. Before I did my modes in the sig I was getting 5 to 6. First mod I would do on your rig is the mouth piece and erg block plate. good luck

Ran level 2 yesterday for close to 4 hours up I 35 and through MSP to St.Cloud. T/H mode durring braking never saw over 70% turbo vane position. Sill felt like level one was better. I'll be calling EDGE again to ask WTF..........

This morning I had the ECM reflashed to Stock at a freinds shop in St. Cloud. Drove the final 3+ hours home in stock. Done towing till about July.

Wow! I guess every is right when they say ever single is different from one another and handles tunes differently!

It is pretty amazing to see the difference between how everyone's Evolution works!

Thanks for all of you that reply to this though!

Just got off the phone with EDGE customer sercice and again I was told that there is no turbo brake function programed for the 04.5 - 05 LLY.:mad:

Did you ask them if they would ever update the Evolution so that it would have a turbo brake function?

Yes the guy I talked to (service rep) said not that he was aware of. I did not speak to an engineer. I kind of got the impresssion that they have been getting quite a few calls about the subject. Soooo, it's likely they know poeple want an update. Whether they do anything about it is something else. Maybe if we keep annoying them about it they'll give in and get it done.

It more likely that they will take away the turbo brake that they do have on level 2 out for good, rather then take more resource to improve it. Let's face it. There are newer trucks coming out and they have to take care of the current vehicles too.

When I first got my CTS 1 year+ ago, it had some pretty bitchin turbo braking, with every update it seems as if the turbo braking becomes less and less.

I kinda think it is BS, since this is the #1 reason I bought this programmer, I tow between 16k and 22k lbs, and go through brakes once a year, and it really helps. But now it seems as though they are phasing it out or something.

I emailed them about a month ago with my concerns and never heard anything back.

All I want is some ****ING turbo brake and ill be a happy camper.

I hear ya. I got my ECM reflashed with the latest GM files about a week ago. Havent run level 2 yet but I'm hoping that it works a little better than before. For what it's worth I think level 1 should have turbo break also since Edge reccomends it for towing anything over 8K

By what everyone has been saying, I am afraid Crashburn may be right. I understand they wouldnt want to use more resources to improve an older trucks turbo brake, but instead of not improving it, why would they take it away.

Just because they are not going to improve it I dont think they should take it out, they should leave what they had in it and call it good.



So if you buy a new Evolution right now from a company, do they update it, or is there a chance that they havent updated it in a year?

I was just saying if the guys keep complaining about how week it is & they do not like it they might just say forget it, then. The reason they left it in there is because some guys really liked the turbo brake.

I would think they would want to make their customers happy, but maybe not. Seems like they'd sell more programers to the guys who have trucks that are out of warranty than those who still have the factory warranty.

I think they do a good job of making customers happy. All I can say is to call in and ask for a feature request. Tell them your concerns. They do look into what the majority want.

I bought mine about a year ago and have not done any updates. By the sounds of it, the updates are actually getting worse for the level 2 towing mode. I am planning on towing about 13k around in a couple of weeks and was going to look into updating.

Please correct me if I am wrong, but it looks like laying low and leaving it alone might be the trick until they do some improvements.

Also, on a side note, Is it true I should run level 1 instead of 2 with a load over 8k or is that just with the newer program for level 2?

Just my opinion, but level 2 is the level I would run. That is the level they originally on had the turbo brake on. I have not heard anything about level 2 not working for some loads. Give Edge a call.

Thought I read somewhere in the manual fine print not to use level 2 for towing more than 8000#. Tried to find it later and never could. At Edges website in the FAQ section it states not to tow over 8000# in level 2, although it also makes it sound like it it talking more about the Attitude w/juice. So I called Edge for clarification, Nore than once they confirmed that statement. Finnally the other day I got an explanation as to why. The tech said it's more about EGT's (quoted "up to 1450 degrees is ok") than anything else. If your EGT's look good then things should be ok.

As for the turbo brake fuction. I was told by another company (PPE) that there was a liability issue programing a VVT to opperate as an exhaust brake, unless the oem had designed it to be opperated as an exhaust brake to begin with. No other details were given. That may be why Edge has done away with it in the LLY programing.

OMG. Liability issues!? Why doesn't that surprise me. This world is so worried about money and steeping on other peoples toes, and free rides, and politically correctness that if you look at someone wrong they want to sue you. It because of these idiots that makes everyone have liability issues and such.
That doesnt surprise me one bit. It actually really sucks. Banks told me there is no programmer that does it now as well, unless its a fleece turbo brake or such.

And PPE wants to give Edge business, right? Take that comment with a grain of salt.

I never mentined any other company to PPE. I'm also not trying to bash Edge (this time anyway). Just offer a possable reason that the turbo brake feature is not available for the LLY with the Edge products.

I only asked PPE if their (PPE) programmers had a turbo brake function. Their reply was that there are liability issues, as I said before. And NO, they don't offer turbo brake programming.

So You have other information???? Let's hear it.

Does PPE offer the turbo brake on the newer truck either? Just curious?

I have the turbo brake on my LBZ & it works great. My truck was not designed for the turbo brake... I have heard from other LLY guys that they love the turbo brake so who knows. I would think the basic reason would be it cost money to devolope things. There are what 2012 models coming out that they need to program to. Most company work hard to get the new products out. When time permits you go back & do the older products. Just my opinion.

Definely true on the EGT. I have to sound an alarm at 1300. I have never gone over 1200 hauling.. I think you LLY boy run at higher temps. however..

Mine would average around 1200 towing 8000# on level ground at 65 mph or so. It gets to 1300+ pretty easy. Had alarm set at 1350, so I never got much over that. Hoping my new AFE turbo MP helps keep the temp down a little.

Yeah, that should help you out with the LLY.

Called Edge about a week ago, getting fed up with the BS.

Let me start by saying, I LOVE their products, before the evo I had the juice/***.

They fed me some BS about how the LLY NEVER had turbo brake, I called BS on him, and told him not only could I feel it while going down a hill, but I could watch my boost go up and my vane position near 100% (back in the day).

He said nope, you are wrong, never had it, never will. So then I asked him to program my truck to an earlier change log. He supposedly did, still havent hooked it up to see if it will work more or not.

BULLSHIT

They do not support the LLY Brake because it seems to work well for some but others it does not feel much. The source code is still in there. You will not get a person to say they have it because they do not support it.

Waste of time, took away my turbo timer option and maintenance manager, didnt even drive it on the old program. So put it back.

Well of coarse it did. You ask him for the older program that did not have those items.

I bought the Evo just for the "turbo brake feature". It don't work period on my truck. Wished I had called Edge before buying. I tow nearly 17,000 lbs and level 2 will limp my tranny. Have not tried level1. set to stock after limp. It does help with mpg and egt was close to same as stock.

Wow, level 2 limped your truck? That sucks. Try level 1, one then.

Should have posted while towing my rv in the hills or a 60 mph head wind. Really, coming thru Kansas wind was so strong you could not stand up straight in it. We were driving straight into it.

So how good is the fleece turbo brake? Anybody try it on an LLY? Is it worth the $800?

Really disappointed with edge on this...

The EVO did not give me a turbo brake. Called Edge and they stated it is not supported on an 05 lly. Big disappointment.

You did have the tow haul button in, right? There is a slight delay before it kicks in on my truck (lbz) but with slight braking it works awesome..

Did you try level 1 yet or just the level 2 & then go to stock?

2006 lly is supported. Just not 2005. The computers are different according to Edge. Yes I use tow/haul mode. I will probably try level 1 next pull. The only real benefit is slightly better mpg. I have ample power stock. I do like the "gauges" though. Will likely get someone to tune a turbo brake with efi just no power increase.

I dont know too much about EFI, but could you have someone just do a tune so that when in tow haul (or possibly even when its not in tow haul), and the brake is pushed it moves the vanes making a turbo brake; as well as still run the evolution on level 2....?

No, I understand the Evo would override the efi tune. Would just use the Evo for gauges if I go that route.

If you are going that route, better to have the insight. You can switch your tunes & the insight monitors more...

so this would work then.....?

Actually NO. The insight is not a programmer, the evo is. The Evo would over write the efi tune you would buy for the turbo brake. Besides any good turbo tune would be better than the evo anyway. Just use it for the guages if you already have it. Or sell it and get the insight.

ohhh okay that makes sense
