For fuel I have the walboro 255 hp, the supra 440cc injectors and I'm tunning with the SAFCII. What size were the stock injectors? Why when I'm in low throttle loop (actually idling) and set the SAFC II to -50% am I still at 10.3 to 1 A/F ratio?
I brought it to get it tunned today and the guy wouldn't touch it because it will not even idle at above even an 11?
Please help me out; I need my car for daily driving in the summer and I will only have a week to work on it before I start my summer internship.
Thanks for the help,
Derek

MANNY- Yeah, the Honda guys wire in a resistor box, mostly when using the DSM injectors. However, the OBD-1 Honda harnesses already have a pre-pinned plug that you can almost literally PLUG the resistor box into.

To the OP, I don't know if just adding a resistor in the circut would solve your problem or not, but you could try it, and if it works, POST IT UP so others know that it DOES work!!!!


I wired the 4 resistors (10watt, 10ohm) into pins 11, 12, 24, and 25 about 3 inches away from the ecu... Still runs like a pos. any thoughts on why that didn't work? I'm thinking of moving the resistors under the hood in the engine bay (the temperature has no effect on the resistors) but I dont see much of a difference electrically to justify the switch.... thgoughts?

I can find it eventually I'm sure, but do you know or have any info on that resistor box for the obd 1 harness/ plug that they use? I don't know too much about electrical.
