So I rewired my fuel pump and now the AFRs are in the 11.5 range and the cars stinks like gas badly. I am going to slowly start pulling fuel out around idle but wanted some general help so I don't over do it or make it harder for myself.

I was originally thinking about trimming fuel from the vacuum range under 1500 rpms but not sure exactly.

And what is a realistic amount of correction to get the AFRs back up to a normal range, and what AFR should I shoot for at idle?

Thanks very much!

Anybody run a rewired fuel pump with the Rtek?

Is it easier to just use the variable resistor function or should I be tuning the fuel tables?

sounds like your fuel pressure regulator is being overrun. i usually shoot for 12.5 to 13.0 AFR at idle

I just installed my 2.1 this past weekend and I have a rewired walbro 255 and I'm getting 11.5 AFR at idle as well...did you get this figured it?

As mentioned get an aftermarket fuel pressure regulator that can keep pressure correct at the higher flow rates.

Don't go tuning the afrs to match fuel pressure creep.

Ah, thank you. I didn't see where it was recommended to get a new FPR.

Also, I rewired my pump 8 months ago and my AFRs were in the 13s at idle. I just installed the rtek and 720 secondaries this weekend. Now 11.5

Did you setup the injector settings to 550x720?

Yes I did

Did you go through the idle setup procedure where you can adjust the 'var-res'?

Yes, sir! I just noticed today that when I modulate the varres my AFRs drop!
