    With that mounting bracket it would be 1994 to 2004 3100, or 1996 to 2004 3400. However the same module and coils were used as far back as 1987 on the 2.8 and 3.1.

    probably 99% of used injectors I've come across that paint has been worn (burned?) off, so it's almost better go by what throttle body unit the injectors came out of.

    The AUTOPROM also has 3 analog inputs that can be used for injecting the WBO2 data (and other sensors) into the datastream. Eaglemark made a write up on hw to do this.

    Emulation is great, because you can make changes without having to shut the engine off, and without needing to repeatedly program EEPROMs... It's not about being able to change the cells as they are...

    When you order ECMs from the parts store they don't come with the MEMCAL or PROM, so you would still need to source that and/or program your own EEPROM to be successful.

    That being said, some of...

    As I understand the purpose of the additional inputs, they are for logging reference only and will not modify the actual function of the ECU/BIN/Tune file loaded to the Cobra RTP. It also sounds like...

    If you use the wrong XDF, you usually get garbled maps, and/or values that make little to no sense.

    If you modify a bin with the wrong XDF, you will likely be changing things that aren't what you...

    What you describe is just a light, not a CEL (Check Engine Light). The CEL gets 12V ignition power and a wire from the ECM that grounds the light to turn it on. I don't recall the pin number off...

    7747 ECM? If so did you also swap the CALPAK for a V6 CALPAK? If you didn't you are likely seeing a cyl count mismatch. Soft codes won't be stored if you turn the key off, so you need to stall the...

    $100 for an impossible to find MEMCAL is pretty cheap.

    Just for reference, certain V8 MEMCALS, that were produced in much higher numbers than the LG5 MEMCALs can fetch 2 to 3 times as much.

    There was a place that made a BT version, but it was more miss than hit with connectivity. The 8192 baud rate of the GM ECU doesn't play well with other communications protocols.

    You still need additional hardware to make that work. There's a MAX232 IC and supporting hardware needed to make that work with the GM ALDL databus. I have one that I made out of a similar USB to TTL...
