i have put two different mafs on the car. with the maf pluged in it runs really rich an unstable. unplug it an it runs beautiful 14.5-15.5 afr rpms at 950. i have done a boost leak test an everything is good but s tiny leak on the tb shaft seal. PLEASE HELP

car has kelfords 272
fp red stock injectors cause it wont idle on them so im not putting the 880s in yet

an the rest of the mods in my sig

 

did TTP perhaps flash it with an SD modded rom ?

assuming you have a different Map sensor

 

ttp did flash it... not sure what the sd modded rom is. i dont have a diff map sensor

 

someone please help

 

just ask scott to verify.... it probably didnt happen, but its the only explanation i've got for that possibility off hand. He will know exactly what i am talking about. Scott is good at helping customers out so i'm sure he wont mind looking into it. Link him to this thread so you dont have to explain anything.

 

Speed Density rom shouldn't matter if it has a MAF inline or not, plugged in or not plugged in, it will run the same.

OP, you need to log the car and see what happens when you run with a MAF. Something is not right.

 

i didnt think so either... but not sure what else it could be. He is seemingly working in reverse lol

 

well im about to load a map from tammer 4ws tuning he has been trying to help me, its a nightmare makes no sense y it would run so good with maf unplugged

 

The only record of a reflash we have according to your itrader feedback is from 4 years ago?

What did you change on the car that now 4 years later you are having issues?

Kelford 272 camshafts were not available at the time of your itrader feedback rating nor was speed density an option.

Omnipower 4 and 7 bar map sensors were not available at the time of your reflash 4 years ago either so it sounds like your map sensor change has screwed up your idle.

It sounds like you shorted out your BAROMETRIC SENSOR IN THE MAF OR MAP SENSOR AT THE INTAKE MANIFOLD>

 

scott i still have stock map sensor last tune was on the dyno it was around last april at your new shop. you were trying to fig out the idle prob when i got there before we tuned it. you threw new plugs in shecked compression cam angle sensors etc white 06 ix. the exhaust was so loud it kept shutting ur computer down. you gotta remember now. lolol

 

What was the name?

 

either bj powell or william powell paid with by a cc under lasasha underwood

 

You may want to try a new ISC Motor. Idle stepper motor.

 

that would let it run perfect with the maf unpluged???

 

If the idle has a hard time adjusting upwards, however if the maf plugged in drops the idle then it does sound like the baro reading or wire from the maf sensor is problematic. If the car thinks the altitude is higher than normal than it can affect the idle quality. Unplugging the maf disconnects the baro input to the ECU.

Check the baro wire at the ECU as well as at the maf plug.
