I have transplanted a 1994 L99 into an S-10. I am not a mechanic, or an electronics expert and I don't understand much about programming or hacking. I manufactured a cable as per dwg from http://www.mindspring.com/~amattei/aldl.htm (thanks, Andrew) and have tested it and it seems to work fine.
The engine turns over, has spark, and the injectors seems to be firing, but I still have a no run condition. I have installed the fuel pump from the 94, but haven't checked the pressure.
I think that my problem is with the VATS. I used Pcmread to read my PCM and emailed Dave @ carputing.com, he said that my pcm is VATS enabled.(thanks Dave.)
I was wondering how I can get any of the free software out there to show me the VATS enabled. I have dnloaded and looked at Data Master, Pcm comm, Efi live, Carbytes, and Cats engine tuner. None of these programs show me the VATS enabled or disabled.
I am not sure of the condition of the engine I have. I would just like to get it running, but I am not worried about making performance enhancements at this point.
Is there any way that I can disable the VATS in my PCM without purchasing an expensive PCM editor program?
My other option is to build a VATS module replacement. I have heard that my VATS module sends a signal that is 3 to 5 volts at 250 hertz. Can I just make an electronic device to generate this signal? If I can, how could I check that my PCM is satisfied with this signal? Where could I find a schematic to generate this signal?
Any help would be greatly appreciated. Thanks, Kevin.
