Help setting up Power FC - SR20 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I recently got my SR into my S13 and decided to grab some injectors and am having some issues setting them with the PowerFC.

Things worth noting: I am running a 255lph walbro fuel pump, stock compression, stock fpr, 850cc modified wrx injectors, z32 maf, and IACV delete.

While playing with the PFC I decided to reset it and slap a new map on there. Which has caused some major issues with idling. Before the reset the car idled high, around 1,100-1,300 which was fine as this is a track only car. But after the reset the car WILL die.

I set the ignition and fuel map to Enthalpy's base map so that I can try and drive the car to get it tuned with no success. The injectors have been toned down to 43.5% with a latency of +0.18. The injectors were tested to be 3ms @ 5000rpm and 12ms @ 2500rpm. And Subaru's specs for the injectors latency are 2.79, 1.49, 0.98, 0.68, 0.38.

Sadly since the car is extremely sporadic I am unable to get a stable AFR. Idle has been played with, before it could idle low as hell @600rpm, but now setting it to 1,400rpm won't even work.

Any help with this situation would be greatly appreciated. I am very new to the PowerFC but I have done my best to learn about it every way I can. If you have any ideas or know a way to help I am more than willing to listen. Thanks again.

This is also the same map it was running before reset.
