Thread: s13 sr20det ecu problem

I have s13 sr20det redtop with gt2871r, 850 denso and n62 maf. With chip ecu from rs enthalpy my idle afr is very rich at 10.2 afr. Injectors pulse at 1.8ms. I use NDS with maptrace looking at fuel map. The fuel map shows close loop (190) from 500 to 4500 and 5 to 15 TP. During idle my tp will not go below 15 to be in close loop. What can I do to bring my idle to close loop or below 15 tp? During cruising it's fine with afr 14.7.

I also have NEMU ecu but I can't start the car with it. What can I adjust in fueling adjustment to start the car.

Thanks.

With the nemu rt ecu I have 0% injector duty cycle during cranking but injector pulsewidth is 4ms. I have 12v at each injector. Do I have bad injector driver circuit?
