My exhaust will be here on Friday and I want to get a tune ready to flash once I get the exhaust. Do I only have to shut off the DTC's related to the DPF? Or are there controls somewhere to shut off regen like in EFI-Live? I can't find anything and I'm using the 2.2 suite. Anyone know? Thanks in advance!

Anyone?

From what I can find the only thing HPT list "so far" is the DTC's. You'll need to turn off , "P" 0420,1448,244b,2453,2454,2455,2459,2463. I can't find any control tables for "B"2501,2502 or the sensors.

I've posted on the HP forums but have gotten no replys yet.

I have to get rid of this DPF so I stop eating up the extra 1.1 gals of fuel during regen...

I spoke with Bill from HPT and he said they are not pursuing controls/mods to the regen process at this time due to pressure from the EPA. My question from this is, if you turn off the DTC's will it still go into regen? I think I read somewhere that unless you shut the regen process off the truck will still go into regen but not nearly as often... I've got a project that I'm working on with some help so we'll see if this works. I wish HPT would just build the functionality into the VCM suite and put a warning that they are not responsible for any changes to emissions equipment. If there are several other companies that allow this use why cant they? It could be for "off-road" "racing" use only if you know what I mean.

Not as simple as that when it comes to the epa.

Look at 02 sims as an example, they were clearly marked off road use only, but when you sell 100,000 pairs of them the epa isn't stupid & know something is up.

In the end, if your not aware, they made them buy back each set they sold.

We do not want to be in that same boat and in reality want to be able to work with them so we grow rather than go ;)

ppe has an option on there big programmers to shut it off if you go with a 300 hp it does it on its own call them there real good about talking you through i just did it on an 08 d-max the other day pacificpc.com is there sight there all about the chevy guys

I bought HP pro a couple of years ago and just thought it would be nice to NOT have to spend another $450+ for another tuner to do this...

Exactly my point... It would be nice to have full capabilities in a tuning program. I bought this tuner because I read that it had this capability, and now I'm finding that it doesn't. Now, if I just shut off the codes and that works ok, then I'll be happy. But I'm pretty sure I remember reading that the truck will go into regen after so many miles if a regen doesn't happen. I would hate to have to sell the tuning program I just got to do what I was told that I could. But on the other hand I would have a lot more support with EFI. We'll have to see what happens I guess. My exhaust got delayed so it will be here monday, and I'll have to find out on my own I guess. I'll update once I figure this out...

-David

i unhooked all the regen stuff and replaced it with a full exhaust so if it decides to try after so many miles im sure ill have problems i put it in about 2000 miles ago and still no problem though ill keep it posted if anything does happen i know it cost more for the ppe but im like you didnt want to worry about it later on and so far its been great

i put it in about 2000 miles ago and still no problem though ill keep it posted if anything does happen....so far its been great

Just what I want to hear! My exhaust will be here tomorrow and I'll be throwing a tune on my truck to test it out. Thanks for the post!

-David

hope it works out for ya i love mine

Well the exhaust is on and I drove about 30 miles so far. No codes thrown because I set them all to disable :D We'll have to see about this regeneration happening even though all the codes are off. I'll keep this thread updated so others can have the information. Here is the thread with pics of my exhaust if anyone wants to see. http://www.dieselplace.com/forum/showthread.php?t=225867

I HAVE A 07.5 LMM I HAD TO TURN OFF 6 CODES THE ONES YOU MENTIONED(244b,2453,2454,2455,2459)PLUS I HAD TO TURN OFF P0546. ARE THESE THE SAME CODES U TURN OFF FOR A 08

it was a silinoid code stuck on or off cant remember thats the only one i got now we put in a ats package no more probs now

then why do you offer things like egr shut off dtc disable so on and so on just as bad as dpf peramters ? so why no dpf stuff or i should say the rest of the dpf peramters becuase there are sum

We are looking into it further with the help of some of our resellers to see if they are necessary, if they are necessity we will be adding them.

-Bill

defnitaley needed good to here your looking at it. when id your next version coming out when are you gong to hae 6 speed support ? thanks

Wow, I was unaware that HP didn't have full DPF functionality.

Me too... I would have paid the extra $$ to get EFI-Live but from what I read it had all of the DPF stuff...

I'm running a beta of the VCM suite from HP Tuners now and it has tranny support... I haven't messed with it because my tranny is stock but it does support the tranny.

They are necessary! :D EFI-Live has them... HP Tuners should also...

i would like to see the beta stuff i have hpt as well if you need a dpf tune let me know i can hook you up with a stock one in hpt fourm

Um so why do they still sell the O2 sims. Maybe your refering to one company that had some issues....

Dunno

The Department of Justice and U.S. Environmental Protection Agency (EPA) settled a case with a company that had been accused of selling electronic devices that allowed cars to emit excessive levels of pollution in violation of the Clean Air Act. The products are known as oxygen sensor simulators (O2 Sims) and signal to the engine computer that the automobile is functioning properly even when the catalytic converter is missing or disabled. These types of products are known as "defeat devices" and are potentially illegal under subsection (B) of 42 USC Sec. 7522 (1990 Clean Air Act Amendments), which states:

"(B) for any person to manufacture or sell, or offer to sell, or install, any part or component intended for use with, or as part of, any motor vehicle or motor-vehicle engine, where a principle effect of the part or component is to bypass, defeat, or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this subchapter, and where the person knows or should know that such part or component is being offered for sale or installed for such use or put to such use;"

The company had sold an estimated 44,000 units since 2001 and will pay more than $74,000 in civil penalties. It is also required to undertake a buy-back program. The EPA estimates that the O2 Sims sold had the potential to allow emissions equivalent to half a million vehicles with fully operational emissions control systems over their lifetimes.

Thats insane and makes no sence. So will they stop selling tuners because they make vehicles admit more emisions? How about long tube headers for mustangs?

They still sell O2 sims so I guess this suit went no where...

Off road use means for off road use..

i would like to see the beta stuff i have hpt as well if you need a dpf tune let me know i can hook you up with a stock one in hpt fourm

You'll have to contact HPT for the beta stuff... I was talking to Nick @ duramaxtuner.com about transferring a EFI tune with the regen turned off and we don't think it will work because HPT doesn't read those parameters. Look at the file size on an HPT file and a EFI, it's quite a bit different. I'm running my stock HPT file with all the DTC's shut off. I would be willing to try it out if you want to send me the tune :D

If a truck was programmed using EFILive, and the DPF regen was shut off, and was read with Hptuners, you would have an Hptuners file with no DPF regen, you just would not be able to tell by looking at it with Hptuners. If you then put that file into another truck (using Hptuners) that second truck would also have no DPF regen. Just because you can't see it with Hptuners, has no bearing on it being there.

As an HPTuners user I really hope the ability to tweak or turn off the DPF post injection settings will be available in the future. I'm thinking about buying a new truck and after a few years run it on Waste Veggy Oil. I will need to disable or modify the post injection events used under regen becuase post injected Waste Veggy Oil will not burn like post injected Diesel fuel in the exhaust. This is kind of the whole point behind having full tuning ability.

foff667: Any word on the addition of DPF controls for HP Tuners? Maybe even just a beta version for dieselplace members? :D
