I will start tuning my 82 Corvette in spring, still donīt have the equipment, however I am reading a lot already. Also used Win ALDL. At this time I am confused about BPW and Flow Rate or the injectors. I know what it means or what it is however donīt know what to insert in Tunerpro to get realistic values. This car has two injectors 61 and 64, is the flow rate around 100 lb/hr or just 61 and 64 lb/hr?? How to insert BPW in the program, I read somewhere the program calculates this, but how?

Can anybody explain? Thank you.

BPC base pulse constant is a calculated # that takes into consideration the inj size- fuel pressure- and CID. It tells the puter what you are running. that is the first thing you change in .bin. All calcs are made off that. Important.

Injector rate is the flow(lbs or grams) measured at a standard FP that GM used. I believe 12 lbs

BPW and BPC I believe are interchangible
