Using the 28lb injectors off a 1996 Corvette Im in need of these values thanks
injector pulse width vs battery voltage
low pulse width injector offset vs BPW

This is from a 96 LT4 Tunercat .cal file. I believe it a stock file It shows the IFR to be 27.0lb not 28lb.
hmm now Im really stumped Im using TP and I have a bin which I believe is a authentic LT4 but it shows these valuesQuote:

Well now I'm confused. Was there both a OBD1 and OBD2 LT4 in 1996? My file is OBD2 and TC OBD2 IDs it as an LT4. Your file is OBD1 and TC OBD1 IDs it as just a Corvette. But even your file in TC OBD1 has the IFR as 27lb, not 28.
Entering both VINs here https://www.autozone.com/vin-decoder they both ID as 1996 Grand Sports.
My bin was found off the internet I only have tunerpro Im using the wrong mask to open the file Im using $EE that is for 94-95 but the bin looks correct just by looking at other parameters like injector flow rate, revlimter ect. OBD1 was gone after 1993. Im also getting different values for the 24lbs LT1 injectors I dont know why there different they used the same injectorsQuote:

Since the VIN in your bin IDs as a Grand Sport and it has 27lb as the IFR the other data is probably correct for those injectors. TC OBD2 uses .cal files. it will open a bin but will only save as a .cal. You would have had to of purchased it years ago as it is no longer for sale. Everything on that page for OBD2 are just updates if you have the original install. I just happen to have both versions of TC. What I originally posted is from the OBD2 96 Grand Sport file.Quote:

Thank you! yes I dont have TC, any idea why the injector data from my bin is different than your initial? look at the low pulse width table the offsets are the same was this just a error in your original post

here are some bins
I'm not going to look through 6 files. Pick one and I'll see what it shows.
Can you just use these two one is for 94-95 EE and the other is 93 DA3 thanksQuote:

This .bin has been screwed up by someone. The bin has been edited by someone who doesn’t know there are no letters I or O in vin numbers. The letter “O” as the ninth character in this vin number is in error and should be a number 0.Quote:

A Copy and Paste would have resulted in an invalid VIN. But that still doesn't explain TC OBD1 IDing the file as a 96 Corvette in OBD1 .bin format using the EE Definition.Quote:

OBD1 swap in a OBD2 car makes the most sense.
