Ok its a bone stock b18b for the most part and it starts and idles relatively ok except for when it warms up then the idle will fall to zero and the car will die.

Im running uberdata with a chipped p28 with a stock ls .bin with no ELD and closed loop disabled because I have no o2 in yet. The only code it throws is a code is a code 20(ELD).

I’ve calibrated my TPS to .46 at idle (4.9) at WOT. I did a compression test (to rule out a bent valve) which yielded 190 (give or take) across the board.

I’m at my wits end here and I’m running out of ideas for things that could be wrong. I need some ideas guys. Let me know what you think.

EDIT: Also I checked the plugs wich are a dark black which would indicate its running pig rich, although that doesnt explain the weak vacuum.

 

Come on guys, help a brother out.

 

I'm no genius but isnt the p28 for a z6?

yea but he has got it chipped with an ls program right now, which is fine as im running a p28 chipped with an ls program.

so u still throw the eld code with it disabled in the uberdata?? have you adjusted the idle via the idle screw? im honestly not sure what to tell you, but i can give a bump

 

Yeah it still gives me the ELD code with it disabled but no o2 code when the closed loop is disabled. I tried the screw on the TB but it didn’t seem to make much if any difference. Is out for a higher idle or in?

 

turning the screw left makes higher idle
