Default Need some help (SR20DET)

I just upgraded my injectors, turbo, and turbo manifold on my car, and I have an SAFC 2 for tuning. Everything seems fine except when I come to a stop, the rpm drops and sometimes stalls the car. I tried messing with the dec. air on the afc, but nothing seems to be working. Anyone know what I can do? Or anyone that can help/tune it for me in the central area?

Thanks,
Alex

that is definatly not the best way to tune with bigger injectors and stuff in place. I would recomend ditching that and getting at least a cheap daughter board style rom chip ecu so you can have a decent tune made. Or get a power fc. Check on a calum realtime ecu if your low on funds. Calum can be found on sr20forums.

How big are the injectors? Anything over 550cc and it will run rich because the AFC can only add or subtract 50% fuel.

i had a sr in my s13 for almost three years so i can safely say get rid of the SAFC and get a proper tune. either rom tune or emanage ult or PowerFC. If you wanna upgrade im selling my Greddy emanage ult with harness and all instructions

x2.....if you can afford a nice turbo/injector setup, you can afford a tune. is this a rwd or fwd application? if its a 240, theres always enthalpy, from what ive seen and delt with, thats a good choice.

Definitely switch to a ROM tune or something like a Power FC. Also, I assume you upgraded the MAF as well......
