What Gauge Would You Go With?
My thinking is this...either or will be sufficient...
If I only have a Fuel PSI gauge...I would be OK because as long as I maintain fuel psi my AFR should remain consistent....
If I only have an AFR thats fine because if I lose fuel it will obviously show up on the AFR Gauge.....
I am leaning toward the AFR gauge and not worry about the Fuel PSI... what do you guys think?.... Thanks...
A fuel pressure gauge is a must. You need either an AFR gauge or a Pyrometer. Either will tell you if you are running lean or rich.
I think knock retard is critical and afr is good to have especially for tuning. While dropping afr can point to fuel pressure problem its still nice to have fuel pressure directly to look at.Can't have too much info with an FI car.
I use three interceptors and added on wideband, fuel pressure and nitrous pressure. I can add three more sensors if want they would likely be egt, then maybe trans temp and mabye oil temp.
Each interceptor can handle two additional sensors.So three gauges can take the place of like 9 gauges plus you get all the logging and scanning of laptop and you can even run 1/4 mile times with them!
