Anyone replaced engine ECM '05 GTO????
I am going to remove the stock ECM and save it, install a new ECM and get it tuned.
-The factory service manual states that "CKP Variation Learn proceedure" is requaired using the TECH 2 to enter and monitor the learn process. (This has to do with the crank position sensor) The manual says anytime the battery is disconnected this "CKP learn proceedure" must be performed. pg. 6-704,6-705 & 6-706
-The service manual also states "The ECM must be linked to the PIM using the Techline Information System". pg. 10-69 ECM Replacement section
I think this is dealing with linking the ECM to the other controllers.
I have to say this does not sound correct to have to do the proceedure with TECH 2 if the battery has been disconnected. This service publication has not been acurate in other areas and now I question the acuracy of what is require to replace the ECM
If anyone has experiance in this area please provide your input, it will be greatly appreciated. I like to do the research first before I just plug it in. I replaced the PCM in my '94 Caddy and it required a series of specific switch inputs but no special tools
