    350 TPI with a 4L60E, What ECM will control both?

    OK, i have a 93 S10 that i am swapping onto a 94 S10 ZR2 4wd chassis/suspension, i was planning on keeping the stock 93 4.3/4L60E for the time being, but came across a 350 TPI locally for 125 bucks. Its a complete long block with the lower TPI intake, and the plenum and runners and TB can be had for pretty cheap, so im thinking this would be a great setup, with lots of torque for my 4wd project. And while the 7730 is a great ECM that has lots of options as far as tuning goes, as far as i know, it wont control a 4L60E trans.

    Does anybody know if there is an OBD 1 ECM that i can use that will control both? I know i can keep the stock ECM to just control the trans, and use a 7730 to run the engine, but that just seems like alot of hassle and to complex.

    Thanks for the help.

    The 16197427 PCM can be modified to operate a TPI. http://www.gearhead-efi.com/Fuel-Inj...Information-OD Post #6 has a .zip file with information on "How To"

    As well as the 16168625 PCM, using the same PCM modification in the link above provided by dave w.
    This 16168625 is what I am in process of using for my TBI to TPI swap. The 16168625 is what came stock in my 93 Chevy K1500 4x4 and has the 4L60E transmission.
    I'm just about finished with all the nuts and bolts end of it, and am now researching the bin modifications.
    I'm starting with my factory stock BHAS bin I read out of the memcal, and going from there.

    Good plan!

    Attached is a .bin I started with for a Vortec 350 using a 16168635 PCM. Not exactly what your EFI system will end up using, but a starting point to learn from.

    Thank you Dave!

    Just what I needed, is a compare bin to see if I'm headed in the right direction!
    There is a learning curve for sure. But not impossible.

    Thank you,
