Has anyone used or thought about purchasing this software?

I am thinking that some of the "inherent" fuel mileage problems with the currently available chips could be investigated and corrected using this software.

Much like the DMax guys using EFILive, we could lower the requested boost levels at cruising fuel delivery rates (30^mm and lower) to make the 6.5TD run more like a 6.5NA at this low fuel rate.

Thoughts? (I know that is a dangerous question to ask...:rolleyes: )

I'm excited about their OBDII version, said to be out fairly soon. I've had thoughts of going back to the electric wastegate and playing with engine timing attempting to create an ecomony mode.

The recent D/Max piston discussion has me a bit worried about busting pistons with too much timing. I believe extra care must be taken with our lighter duty guts.

I don't know about doing the programming yourself but I do run a Wester's ECM that they programmed (ODBII) and it is great. In using the electronic wastegate if I don't pay attention at WOT I can hit 20psi of boost easy, just normal 70mph highway driving I get 17-18mpg and at 60-65mph I get 20-22mpg. As soon as I attach a load to the truck depending on weight I get 10-17mpg, the 10mpg (at 65-70mph) is with a 10k 5th wheel travel trailor and the 17mpg (at 70mph) is with a small trailor with two motorcycles on it.

I understand the piston concern, however with our IDI injection system I don't believe that we will be able to inject fuel at a rate that could create a combustion pressure spike harsh enough to damage pistons regardless of the timing. I have not read the specific thread that you reference, but I am going to guess that extreme heat was involved in breaking any piston (except for some other catastrophic component failure)...

Crack a piston from heat and overtiming, no. Crack a head or head gasket from it, yes.

This is the first i have heard of this. will it work with obdl ? will it be similar to efi live?

*crosses fingers* i hope so. custom diesel tunes will be in my future then!

I would buy it, I have been waiting to get a ECM upgrade for this reason.

I would rather tune myself with the different altitudes, temps and driving/towing conditions.

No matter what, sounds like fun:D. But now it sounds like I have a problem running a turbo that has no way of automatically changing it's boost without me taking tension off of the spring pot system.

hey chicago is there no way for you to make a vacuum system work on that holset. couldnt you put a vacuum canister on there instead of a manual one.

i really hope it will work on obd 1 cause i want to custom tune so freakin bad. i have debated a d-max just so i could play with efi live. i guess ill have to go back to a vacuum system too. good thing i never took off the vacuum pump.

yea, I took off my vac pump. I also changed the belt to a shorter one too.

I guess I could put a vac canister on there, but the calibation would be totally different then running the GM8. Hell, I am sure that the vac canister would not have enough surface area to provide enough force to hold the waste gate closed to get good boost.

hmm maybe a bigger canister or bigger vacuum pump. i would think it would be worth it to have custom tuning. it would definitely require some special tuning to accomidate that big monster hair dryer

It looks like they have an OBDI only package for the 6.5TD.

Here is a link to the Link to a non site removed

and

Here is a link to some Link to a non site vendor removed of various tables/maps.

I think that this is exciting, however the price is a tad steep for one guy to bear. Would anyone like to entertain a "Group Buy" or is that prohibited here at DieselPlace?

It looks like the OBDII 6.5TD's are left with Link to a non site vendor removedat Wester's, but that is pricey!

Goldsburg, you no longer own a 6.5 do you?

I was thinking of this too for my 6.5 buildup. I want to switch to 18:1 and run a HY35 HOLSET with the vacuum system. But I didn't think the vacuum servo could pull it off by itself either. I figured a turbomaster on the HOLSET set to around 10-12 lbs of boost and then the vacuum one to pull it up the rest of the way. Or you could run a longer arm on the wastegate which would give the vacuum servo more leverage, but it would reduce wastegate travel.

Goldsburg, you no longer own a 6.5 do you?

Well, I am glad that you asked! I have always enjoyed hanging out here with this bunch. You guys (and gals) are much more informative, receptive, and interesting than any of the F_rd guys on DieselSt_p.com. In addition, the trailer pulling thing has pretty much dried up, so I no longer have a use for my F350 CC long bed 4x4.

The good news is that I have purchased a loaded 1994 K3500 SRW, Crew Cab, Long bed, 6.5TD (VIN code F) and NV4500 handshaker! It has 197K on the ticker, but has been a one owner truck and has been VERY WELL maintained! This is the best compromise of family rig, diesel rig, and low cost rig that I have found. The only down side is that it has 4.10's and I LOVE highway driving, but I can correct some of that with a 255/85R16 tire!

Anywho, the 4.10's sorta have me running scared about the fuel mileage, so I am seriously considering the purchase of the OBDI tuner (from Wester's). That would allow me to tweak my calibrations to increase fuel economy, with a mild performance gain. Then I would be just like "The Big Guys" that own Dmax's and EFILive!

Anyway, I fly to Texas on Thursday to pick this baby up and drive 1200 miles back to IN.

WISH ME LUCK!!!!

I have looked at Wester's site but can't find the answer to this question....

Can you share tunes with this program like you can with EFI Live?

Im not quite sure I understand all of it on their page. Can u buy just the setup for the 6.5 only? What is the cost of it if you can? If you cant what is the cost of the whole program?

This link is to the Wester's Link to a non site vendor removed

It looks like the "OBDI TM" is the package to program OBDI 6.5TD's and it runs $1200 bucks. The WK means that it can be shipped inside 1 week.

I am assuming that if you buy the EPROM burner, that you could develop and share tunes. Otherwise, it looks as though you could save the .bin file that you tweaked and email it out...? I am not that well versed on the programming lingo, but this is what I have read on other sites...

Would you need to do a 'relearn' of some kind following the installation of a new PROM?

From Wester's site it seems as though you have to spend $1299 on the software and then an additional $1000 on the burning package.....$$$$$$$.....ouch!

I've been eyeing this software myself and have been thinking about talking with my buddy in Tilley. Was actually contemplating creating my own tunes to sell :D . Just need the interest in it.

Im looking into buying this software as well. many things i would like to tweak for serious offroading that you just dont see on a street chip.. Looks like a good package..

Im also currently working on a design that will allow me to flash the firmware for us obd I guys..

Golds, hurry up and sell your 94 and buy an OBDII! We are both in Indiana, we could split the costs.

FYI, my truck has 4.10s as well......

If I sold the '94, I wouldn't be able to split the costs of the software with you....


As my wife would have shot me dead shortly thereafter...:D

Word on vendor links guys, you can't direct link to a non supporting vendor that sells product similar to advertising vendors of the site. Kennedy is or soon will be offering the Wester scan tool, you can link to his site for it when it comes out, but for now since Wester isn't on our vendor list you will have to refrain from linking to that site.

But the OBDII is cheaper, no EPROMs and no programmer required! My wife has lots of friends, she'll find you a new wife, right after the doctors get done removing the slugs!! :D

Roger that TD.

John Kennedy - Are you selling the software and burners from Wester's? Do you have to be a "dealer" to buy the stuff?

Inquiring minds want to know...

Can you PM me with details (including $$) since you are not ( I assume) a supporting vendor and open discussions of such may be dicey?

Thanks!

Goldsburg, you have a PM.

Given the current "political" climate (not here) surrounding the "masses" having this type of equipment and knowledge in their hands, I doubt that it could ever take. However, I am sure that posting results or work toward getting results would be acceptable in this forum as long as no non-vendor links are used. The "powers that be" may also disuade any speech about results obtained that do not include the use of sponsoring vendors products, whether current or alleged...

Anyway, going mechanical with my 1994 will probably get me where I need to go, especially since I have a manual trans. Special thanks to member bobbiemartin...
