Looking for BMCB Bin File
 

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.

Looking at my library, the BKKR bin is an $F0 Mask ID. The latter $F0A bin file you are looking for is the BFDM. At least that's the broadcast code I have. Not sure if there was an earlier or later update beyond that.

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

Thank you! I found this chart here in the Registry that helps. Do you have a copy of the BMCB file that you could send me? I can pm my email address.

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Actually, if BMCB (F0) superseded BFDM (F0A) a couple years later going by the chip P/N and release date, then I may not even care if I have the F0A XDF.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.

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.

Re: Looking for BMCB Bin File
 

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.
