HI all, Ive been on a steep learning curve with the pcm tuning and have read vast mounts here nd other groups nd tried endless combinations of tunes and think I'm settled with this so far, its not perfect but runs nice and smooth , although did end up using stock marine 4bar fpr with the marine 24lb injectors and found a thread about calculating injector offset vs bat voltage which made all the difference so popped that into a spreadsheet and have included the bin too, any suggestions or input welcomed as still learning and hope this may be of use to others too.
so my astro is 95 4.3 l35 (was cpi), vortec heads fitted, marine inlet, std marine bosch injectors and fpr, marine throttle body, base timing is set at 0 degrees, 727 pcm $0D mask
Thanks
Gary
