I finally got my 29C256 to burn, I am using a JET piggy back and a 88 L98 Memcal. Does the 88 165 ECM differ from the 89 165 ECM? The hole in the ECM seems too small to hold the JET adapter and the Memcal. I don't have the instructions for the JET adapter, Do I need to mod anything?

Your right it don't clear.
careful filing on the piggback might work, dang it's sooo close. Mines not in a case, so it might need some trimming, but it really interfers with the Steet support that bolts to the PCB, hmm, maybe slot the PCB, and then the case a little would be best.
Like I said mine's not in a case so the case might also need some work.

ANOTHER good reason to use the 730 <g>...

With my piggyback, it was still a tight fit into the opening for the 7730.

What I did is dismantle the aluminum case (very easy) and then take a Dremel to widen the opening.

Any more I leave the piggyback for using with an emulator, and just use the ZIF'd memcal for the 730/749/165 stuff.

Just wish we had the winbin emulator. I got to play with an early version, and it was so slick you can't believe it.

Yeah, I had to open up the case to make it fit. Not a big deal just a little annoying, but that is the way it is when doing mods to a car.
