How to Control a 4l80E with a GM 16197427 ECM

Intro

The GM 16197427 ECM can be used as a stand-alone 4l80E transmission controller. By disabling all engine related flags and piggy-backing the harness to your existing ECM you can use your current ECM for engine management and the 16197427 for transmission control. This how-to will attempt to explain every step of the process but it will focus on using the 16197427 with a Sy/Ty 1227749 ECM. Most of the parts needed can be obtained at a Junk Yard for $50 or less.

Thanks go to Jeff Scott, Paul Schwab, and Daron for providing the info needed to make this how-to.

1.) Materials Needed

• • 16197427 ECM

    • • I found mine on http://www.car-parts.com. I ended up paying $35 shipped to my door.

      • Search for an ECM from a 95 Chevy Tahoe

  • Connectors for ECM and 4l80E

    • • I found these in a 93-94 S10 Blazer at a U-Pull-It-Yard. I think as long as you find a GM truck that originally came with a 60E that it will have what you need.

• • • Connectors for TISS and TOSS sensors. These connectors just happen to be the same as the 2 wire connector at the base of our distributor. Luckily I had a few of them laying around from various wiring harnesses that I had grabbed while at a u-pull-it yard.

• • Chip Carrier and 512k C2 SST 27SF512 chip. I used an old Hypertech adapter. If you don't have one I recommend a G1 from http://www.moates.net

• • DRAC from a GM truck that originally came with a 60E or 80E tranny.

• • Heat Shrink

  • Solder

  • Electrical Tape

  • 18 Gauge Wire

  • Hardware to burn Chips(Reader/Writer or Autoprom recommended from http://www.moates.net)

3.) Bin, Definition, Datastream, and other files

• Commented $0E assembly code

• $0E XDF file for use with TunerPro

  • Bin Files

    • BHDF 0E.bin

    • BJDR 0E.bin

    • BMHK 0E.bin

    • Jeremy's bin

4.) Burning the bin to the chip

The 16197427 uses a 64k byte bin. You will need a 512k C2 SST 27SF512 chip as 1 byte is 8 bits so 64kbits * 8 = 512k bits. You can get these at http://www.moates.net for $5.

When buring the bin to the chip select 29SF512 as the chip type. Set the start address to 0000 and the end to FFFF for both the buffer and chip. Select load file to buffer and select the desired bin file. Select write chip. Its probably not a bad idea to verify the data is on the chip after you write it.. When you install the chip in the carrier the little notch of the chip needs to face towards the outside of the ECM.
