Tricks to tuning 80# injectors

[Mizark347]

I have been trying to get my car to run and hold an idle for 2 weeks now with 80 lb injectors and E85. My AFR bounces all over the place form 13-17:1. I tried adjusting the MAF Xer function, injector slopes and minimum PW with no luck. Are there any tricks to use when tuning these using SCT PRP?

injector values should be fixed unless dealing with crank fuel. so I suggest going back and starting over with the value file for the 80# injectors and make sure your maf curve is correct. Also- make sure that you're not experiencing maf wash or turbulence by checking the range of counts your maf moves at idle- should only be 5-10 ad counts, nothing more. also check to see that your isc duty cycle or integrator are not too high.
