Lil'John 02-13-2002, 08:03 PM To convert a ECM from an automatic version to a Manual version, is it as simple as changing the chip inside the ECM? Or does it require swapping out the entire ECM? FWIW, going from 88 Camaro with auto to 88 Camaro with manual 5.0L TBI :p TIA, John 4x4realm 02-14-2002, 09:35 AM you might want to look for you answer at www.trirdgen.org I'm sure someone overthere would no the answer to your question. :) Charly 02-14-2002, 12:12 PM yep, the computer is the same...1227747 for example, it's the prom that contain the memory for each type...manual /auto etc. Lil'John 02-14-2002, 03:22 PM Thanks Charly.... that is what I expected.... but with car makers, you never know:rolleyes: Charly 02-14-2002, 04:00 PM No problem man. Definitely check out that thirdgen site though, excellent info. kaiserman 02-15-2002, 07:16 PM I used an auto computer from and 89 caprice police package along with a 4sp manual and made no mods...Works fine Charly 02-15-2002, 07:20 PM Harry, Are you using a VSS? And are you using the stock harness? or did you buy one? Damn, I wish I climbed up onto your bigass tires and looked into the engine compartment. Charly kaiserman 02-15-2002, 07:41 PM What is a VSS???? I am using the whole harness from the caprice.And I mean the whole thing..I did this because my rig was 24 volt and I needed to convert anyhow.

A VSS is the Vehicle Speed Sensor, which, depending on year, is integrated into the dash speedo, or the speedo gear. Some people who don't use them have some drivability issues, particularly when slowing to an idle. Others don't seem to have an issue without one. I'm trying to decide if it'll be worth the cost (particularly because I need to decide whether I'll get the harness set up for one or not).

Depending upon the VSS you buy, it may have the "spade" for integrating it into the ECM connector. I believe the one I bought for my Cruiser had the spade. kaiserman 02-16-2002, 08:13 PM Charly, I remember now. Mine did not have this as it had a speedo cable. The other Kaiser did as we took the wiring from an 88 chevy PU. Both vehicles ran fine. We didn't hook up the other either.....Excuse me if I am not up to speed on my TBI jargin. Its been a couple of years now since my conversion. | |
