Not sure?

Reference pulses I thought referred to the CAS, 18 pulses per rotation? I would have thought it would take the TPS movement as the zero count position to then decay from that point.

depending on injectors and intake setup ive found some need upto 0.6

for 56* & below I gave it 0.523 & even more for the negative temps but it didn't seem to help at all.

oh & forgot to mention it's running Bosch 1150cc injectors, the intake setup is all stock except for being ported & running a LS1 throttle with adapter to suit.

could be more to do with EOI and spark advance causing AE not to work then if it's a lumpy cam. Assuming fueling is dialed in.

The other thing that is most likely throwing things out is the VE maf is nearly 1 metre from the throttle body seeing the owner wants to keep the MAF out of sight & it's hidden in a pod enclosure!

But yeah fueling is on target!

Bingo!

Just in case anyone wondered how this ended up being fixed. The customer took his car home and found vacuum leaks. Once sealed and fueling modifed 14.7 afrs were achieved for idle and lower for wot.

Thanks for posting back about the technical solution. Ive removed the tail end of this thread as it has gone off topic with content best discussed directly.
