So i should be able to change the numbers to reflect the new TKX signal difference? It has the same as a T56 type, 17PPR...

That's incoming signal to the ECM. The DD Dash I have can adjust MPH by GPS or setting to mile markers. I still have the VSSB(or DRAC) on my 88 so,...

BAKJ was used on a Buick V6 3.3L 'LG7' engine in the 01228706 ECU.

Going back to this chart: https://i.postimg.cc/vH0WjsGV/Memcal-ESC-info.jpg it's clear that there are many ESC circuits (MASK SET=7KR, SUBSTRATE=2)...

Actually... it wasn't me doing the figuring out... a retired Delco engineer contacted me after reading my post and provided the information. So I'm...

Nice work on deciphering the abbreviations.

Having dealt with patents in the past, I can tell you that authors will sometimes intentionally obfuscate what they are doing in the explanatory text...

Will tunerpro pull the bin? I put together a diy ft232 cable to scan. Trying to save money. Will that cable do anything besides display current...

No problem, but the BJYL bin is not the same as the hypertec chip bin. ---- So you need to find the bin for the hyper tech or need to read the chip...

Ok. That stick is called a memcal? Next issue. It is a hypertech chip. I got the truck in 2000 and was told it was chipped and now I know. I...

Yes, 1 long stick.

So all 3 parts are in 1 long stick?

The 16197427 has a Memcal with three parts; PROM, Knock Filter circuit, and Limp Home Fuel circuit. . . The adapter board by-passes the Memcal PROM...

So, it has either a memcal or chip? All I remember seeing was the long blue memcal directly under the cover.
