Got the PM
and you are right it has to be reading pressure and not throttle position. So it is load dependent instead of reading airflow.
My afr's so far have been in the low 10's with a base fuel pressure of 41. Thats with a 375ml nozzle nad a 70/30 water/alky mix. I've recorded no knock with that setup. But everynow and then the car goes retardly lean at hot idle and hot start. So yesterday I mellowed the thing out until I get the SAFC. And returned the base FP to 50 and lowered the nozzle to a 225ml.
But the 46 Trim hit's pretty good @ 25 psi and pulls well past 6k. I'm running 14 deg base timing and 4 degrees advanced on the Cam Gear.
Thanks for the hookup.
