I have a 94 ZR-1 that has the BKKR calibration and looking to upgrade it to BMCB. Does anyone have a source to download the BMCB bin file?

I think the BKKR was the latest upgrade for 93-95 LT5s.

That?s what I thought until I read this in a presentation from Marc Haibeck.
?For ?93 to ?94?s GM issued BMCB with Product Service Bulletin 576514 dated 18 September, 1995. It addresses a problem with a sag or surge on light throttle acceleration below 2500 RPM. It also corrects an intermittent ASR error that a few cars had.? I read that BKKR was released 11/12/93 and was replaced by BMCB. Last edited by 98indypacer; 12-18-2022 at 10:35 PM. |

I found a copy of the BMCB bin file. Its identical to the BKKR bin as both are $F0 bins. The BFDM bin is an $F0A and appears to be the latest update.
So to load it, u will need the $F0A .xdf for TunerPro

![]() Does anyone have $F0A XDF? I have $F0 but have not seen an $F0A to download and searches are coming up short. *edit* Actually, if BMCB (F0) superseded BFDM (F0A) a couple years later going by the chip P/N and release date, then I may not even care if I have the F0A XDF.

For what it is worth, there was a $F0A .XDF here.
http://www.gearhead-efi.com/Fuel-Inj...ull=1#post2697 When compared to F0 there's little different in the F0A XDF other than unique IDs and address changes in a couple volumetric efficiency tables. Would be interesting to compare the BINs for them.

I think u could essentially disregard the BMCB and just load the BKKR. The diff between the FOA and FO is pretty insignificant at this point.
