    You might be able to do a security relearn and get the VATS to work with the new bin. You might need to make the VIN in the new bin match the truck/*BCM

    Just guessing here, but could it be a security issue? Perhaps you need to do a security relearn if you didn't disable VATS. Also check to make sure that no pins backed out when you reinstalled it. ...

    You need to install VX Manager and during the installation, check the box to install the J2534 driver with it. After it's installed it will work. You do not need to have VX Manager open when using...

    The 16197427 PCM can be set up to work with the 93-94 trans or the 95 trans and can also be set up to work with mpfi. Perhaps someone here can help you set up a bin to work with the TPI and either...

    I'm pretty sure it's just for debounce, so I don't think the exact value is critical. Maybe something between 0.2uF and 0.5uF? You could probably just add the resistors to test the input. Let us...

    I found an XDF for 12587603 on NSFW's Github that has the A/C System type defined. I haven't checked it to know if the checksum is calculated properly. Be sure to verify it before flashing.

    I think you may have sent me the wrong file. The 2GCEK file is from a 2003 Silverado with a 4.8L and both files have OS 12579405

    It looks like I'm not going to be able to get those bins converted to HPT today. I can't find my HPT dongle. I think it may have fallen out the door of my step van :(

    My guess is the resistor that is in place of the the capacitor is there just to keep the unused input low. The 3k is a pull down and the 100k resistor and capacitor are probably for debounce. I...

    I've never used EE Hack. I'm not sure I can help you with this one. Sometimes when I have problems with a program, running it in Administrator mode helps.

    Nice work. I don't have the time to convert the bins for you today. I'll try to get them for you tomorrow

    It is possible. I'm used to seeing a dedicated ground. Perhaps GM initially tied it in with the other grounds, then later switched to giving it it's own grounding point. Any difference of...

    I'm aware. I don't have access to a big block TBI to look at for reference, and finding reliable info about details like this is difficult. If I had access to one, I would find and verify the o2...

    That is exactly what I'm saying.



    It will be a small gauge tan wire, maybe 18awg somewhere on the back of the engine. It should be mounted by itself, not doubled up with any other ground...

    I will say one more time that the single wire O2 sensor DOES have a dedicated ground that goes back to the ECU, but it does not go directly to the sensor



    O2 sensor is grounded through the...

    Sometime in the (probably distant) future, I'd like to examine the hardware, and verify that there is in fact a difference. It seems unlikely to me that GM would omit hardware for an input, unless...

    Interesting, I was not aware of that. I don't believe the difference is related to the IAC drivers, but that doesn't mean that those service numbers don't have additional hardware differences in...

    The IAC drivers are for the Idle Air Control stepper motor used on drive by cable throttle bodies. All of the PCMs use the A/C request input to control the A/C relay output. Different calibrations...

    I'm glad you're making progress. It's best to make changes to one thing at a time, when possible. Save a new bin with each change and keep notes. Focus on one area of operation at a time, like...

    Regarding the high idle, is your thermostat working properly? Is the ECM reading the ECT properly?
