hi fella's!
I'm having trouble starting the engine.
ive checked continuity of all necessary wiring and its fine.
i'm gonna upload my ROM file for some to have a look at.
to see if you could help me out.
just a side note... what should be the cranking air/fuel ratio be i'm betting 14ish-1?
I'm also using a UEGO AEM wideband meter.

Re: hard starts on built b20/pr3
You cannot accurately measure cranking air fuel ratio, as there is not enough movement of air and the o2 sensor will not be fully warmed up.
Have you discussed this issue with your tuner?

I noticed when i swapped over from 10.2 mm leeds to 7.5mm leeds the motor almost kicked over but my battery went dead. i researched that too much thickness in cable could be a contributing factor. So I'll try again tomorrow and you fellas know what happens.
