Ok, so not much of an update today. Basically we have done a few tweaks to various parts. Tordne has suggested retaining PE mode in addition to table B3647 as both have their pro's and con's.
Id like to reenable DFCO and Lean Cruise shortly. Though that throws a few spanners in the works if you still want to tweak your VE table. I also thought that using B3647 to run semi closed loop, where it will use Short Term Fuel Trims (STFT's) to maintain AFR at 14.63 would be a good idea. Though Tordne made a point that if everything is 100% correct you wont need STFT as nothing will need correcting. So yes, I think things are pretty close. The main reason Id like to make a "final" tune is so that I can get the laptop and cables out of the car and go for a proper drive. Having laptops balancing on the seat with cables everywhere does not make for a spirited drive.
Of course closed loop may still not result in a commanded 14.63:1 AFR as the O2 sensors are not in their stock location. Others have resorted to altering the O2 switch points in order to bring these back in line. I think mine are stock HSV R8 which Im not sure have headers from the factory. Anyway the best way to check is to operate in closed loop and check the AFR. Mind you Ill be using the WB02 to output NB02 signal to the PCM, so the LC-1 will be measuring itself. It will also only be measuring one bank of cylanders so thats not the best in any case.
I bought a Fuel Injection book from a US company for $8US so will do some reading there. Maybe some more revelations will surface.
