Question about A/F ratios

Onefast99gsx · 10-07-2005

I spoke to Thomas of Dsmlink and he said the same thing. He said normally, it should have shown with the O2 readings but oddly it didn't so that's why he said to never go by O2 readings.

Yeah i made at least 8 or 9 60-90 runs last night. I know it sucks the fuel bad because i can see the difference on the 'ol gauge. You wouldn't believe how many pulls i did over the summer trying different stuff. I just never looked there to find it off like that. And even if it had been on, i probably wouldn't have caught the pinched line for who knows how long. The pinched line made it so it was never detected on a boost leak test. Any time i reached knock i always backed off it

Dam i'm happy. The car has so much potential at the track. I just have to take it there.

glad you figured it out.

......reasons for possible "knock"......
1) Failing FPR, inconsistent fuel pressure will cause
a great strain on injectors, and make the car
virtually impossible to tune. Injectors are rated on
a 43psi baseline, and are expected to rise in a 1 to 1
ratio. Any deviation will change in how the car is
tuned. By running a lower baseline pressure, you
'shrink' the size of the injector, and when the car
doesn't rise in a 1psi fuel pressure to 1psi boost
pressure, the car is near IMPOSSIBLE to tune
correctly.......

I remember writing that to you in an email. I didn't mention to check the vac line to it however. Are you going to the track on saturday now?
