I put a tw chip on my buddies truck for him and it sputters only on the Smoke setting. Is it not gettin enough fuel or whats wrong? Thanks

sometimes that can be due to injector issues. Could be sticking/worn out. Same thing happens with my buddies OBS when he has it on the highest setting

HPOP could be worn and can't keep up with injectors, also what are the injectors stock or higher capacity?

 

[Black Pwrstroke]

Will it ruin the motor if he runs it on the higher settings?

 

[Black Pwrstroke]

STOCK everything

WHen it sputters its at IDLE.

Are you sure you got good contact where it plugs onto the PCM circuit board? I would check that first.

 

[Black Pwrstroke]

Ya the 5 other tunes work PERFECT

How about getting some readings on the HPOP and the fuel pressure? That will answer a lot of questions.

Also, it needs to match the PCM. The code is different and likely if it doesn't match the PCM it will load it into an area of memory in the PCM the computer will not like.

Test the ICP while idling... normal is 600-700

If you test fuel pressure it should be 60 +/- 10 psi @ idle.

Does it do it while driving?

 

[Black Pwrstroke]

maintain can you explain the ICP test. If the pcm code wasnt right then y would the rest of the 5 tunes work and not the smoke setting.

I had the same problem with a ts chip. It worked fine except on the highest setting it would sputter and hardly run. It worked great on all the other 5 settings. I sent it back to be reburned and that fixed my problem.

 

[Black Pwrstroke]

It does it while driving also. I tried callin Tony but no one was there so il call him in the mornin and seein what he says

 

[99SMOKR]

it doesnt sound like mechanical failure if the other settings work fine. And if it does it at idle that would point to computer/tune problems also.

 

[shocker998md]

sorry for the thread hi jack, how do you test the HPOP i need to know because i think may might be whats giving me a problem with my truck

 

[nic0084]

Ive had the smoke tune on two chips... thats just how it runs at idle, kinda lopes.

 

[Marty]

YOu can do the ICP test with a good scanner or you can use a high quality gauge that reads up to 5,000 psi...

my truck lopes almost as bad as my drag truck with a .649 lift solid cam when its on the highest setting at idle but if your on the skinny pedal it just screams like a raped ape ...lol
