Running lean at idle
Posted: Sun Feb 08, 2015 7:15 pm
I just bought this car a couple weeks ago.
Fully built d16z6 on 25psi on e85
My idle is off the wideband lean same with low throttle steady at 2k Rpms. Full thottle is perfect 12.3 age. I haven't hooked up the wideband to the ecu yet. If that will make a difference or make this any easier I will. White wire on wideband to eld on p28 ecu and remove resistors r136 and r138. That's all that's needed there I believe. My low speed fuel maps don't seem correct to me. I'm not a pro by any means but I have read for hours about this. I'll post a pic of low speed fuel tables in low speed ignition. I'll say now I feel more comfortable adjusting fuel rather then ignition. I noticed they only have 1000cc inj fuel trim and it has 2000cc id injectors. Fuel pressure at idle is 53psi. Also at idle I'm in column 4/5. No vacuum leaks that I can find. Thanks in advance for any advice!!!
