AXXB vs ARZU and Other questions..?
Anyone know the difference between AXXB and ARZU? The only difference I can see form the Gearhead-efi BCC decoder is tire size. Can I use either of these with a 7730 in a stock 305 TPI setup?
I want to replace my MEMCAL because I opened up my ECM and found some weird MEMCAL in there that's for a 350 corvette. I'm also replacing my refurbished Delphi 16198262 for a stock 7730 because the refurbished ECM has been acting up. I just want to put everything back to stock...Any ideas?

If you have both bins just do a compare in TP but if the car is stock just go with the original bin, otherwise I would just start with a S_AUJP bin.

The bcc differences are going to be minor to cut emissions. The axxb is available from amazon.

Odds are the ARZU calibration has the vehicle speed limit set to 254 MPH. While the AXXB calibration has it set to 120 MPH (+- 10).

Thanks for the info. From what you are all saying it looks like the differences are miniscule and I can use either PROM in the 7730 with stock 305 TPI with no problems.
