runs like balls at cold start with new injectors

[thebeewantsboost]

my car runs like crap on a cold morning hardly wants to stay running. it runs super rich and i figure thats because of the injectors however. i've been unable to change that. i've played with numerous tables. i've looked at vipers site and nothing seems to be working.

need to scale the IFR table. http://redhardsupra.blogspot.com/

It is scaled.

Not correctly if you're having cold start problems.

Re: runs like balls at cold start with new injectors

ok, i'll look up everything and give it another shot. if i change my ifr table is it going to affect my maf tune?

Re: runs like balls at cold start with new injectors

i did change my ifr.... and even used tiny tuner to add the voltage offset. it was still pig rich. talking 11.0 ish. maybe richer.
the ifr was off.... after going back through it... i remember not doing it exactly correct because it was running to rich or lean one of the 2. i adjusted the cold start tables but don't think i saw a difference from that again either.. won't know until tomorrow... ran out of cold starts haha

Could it be because my maf table is off now? I would think that was the case except my maf tune has me running lean after changing the IFR

Yeah, you have to retune the maf definitely after messing with the IFR table. I couldn't ever get that damn injector table to work for me. It gave me some real funky numbers when I tried it that would obviously make my car wayyy too rich to even run so I gave up on it.

Does the maf table affect the cold start numbers. Or should I have a good cold start if the IFR is dialed in. What ar should I try to attain for cold start. I. Was thinking 13.

Does your car run fine on a cold start blizzard?

Re: runs like balls at cold start with new injectors

Yeah, it starts right up every time. Runs better before closed loop kicks in too. I'm not sure on the target AFR you want during start up.. I'll pay attention to mine when I start it up after work today.

Re: runs like balls at cold start with new injectors

Mine starts up fine it just runs rough until closed loop @ idle and will try to die on a cold morning driving to work. By cold I mean 40

Re: runs like balls at cold start with new injectors
