    Reading gm memcal

    I would like to read the bin from a 94 gm 6395 pcm without any desoldering. I know the moates HDR1 will do it but for me it is the $10 and then $50 shipping to me so just trying to see if any other alternatives. I have a apu1 and g1.

    You could cut and bend small diameter paper clips into short pieces and insert them into the Memcal, and then bent the paper clips to fit into the APU1.

    There are several stock .bin files here: http://www.gearhead-efi.com/Fuel-Inj...ams-Tuner-Info!

    If the bin file you need isn't in the link dave w provided, let us know and maybe one of us has the same memcal and can do a read for you.

    The burb has the motor out and is stored so took awhile to get to the pcm. It is BHDF and by the looks of the dust it is original. It is a canadian build so don't know if that changes the bin. Anyhow I found one on Dave's site which I think are stock bins. For xdf I have Advanced $OE TPS v250 and for adx I have A220 trans2 $OE TPS v250. Are those files the best ones to be using? The modified motor should be going in shortly so will start changing bin.

    My library of OBD1 .bin files is organized by Broadcast Codes (BCC) only, I don't know the vehicle applications. To the best of my knowledge, the .bin files in the link are accurate. TunerPro has a compare function, which would let you know if there are any differences between the BHDF .bin I posted vs. the link BHDF.

    My limited knowledge of compare says those two bins are the same. Thanks

    I am trying to find the stock factory settings for 1227747 AMUR. I looked at the bin on tuner pro but could not figure out the operating range of each sensor. I'm troubleshooting and via my scanner can see what is out of range but need the factory settings to go off of. Any help is appreciated. Chris_Bama @ netzero d0t c0m

    I've purchased one of these connectors about 20 years ago, although a 34 pin is what I purchased, ironically a 40 pin one cost cheaper than the 34 pin one. Need to cut one side to accept the memcal and the longer pin side need to lose a few pins leaving 28. I know shipping won't help you here either. https://media.digikey.com/photos/CW%...70-40-0000.jpg
