Not sure if anyone has looked at log file, but one thing I noticed was the afr was were it was suppose to be when it was bogging. Wondering if im loosing rt. bank of cylinders with a bad connection on the coils. the afr is in the left side. would loosing one side cause it to cut timing?

Just curious, has anyone looked at the log file but doesn't know what the problem is, or has no one looked at the file?

Finally figured it out. TCC Relay was stuck and didn't open when the brake was pushed some how causing ETC to cut timing. First I disabled ETC LIMITS and the bog stopped and then when driving I realized the converter was acting up. Then I remembered talking to James whom had mentioned the brake sw. because it was bogging if I brake torqued it. I didn't think much about it at first because it had never bogged on the line at the drag strip. So driving to work yesterday I realize the TCC relay and wiring could cause this so I checked and sure enough the relay wasn't opening.

Thanks for posting this. I came across it while searching for solutions to my car's bogging problem. Turned out not to be me TCC relay but I wouldn't have even thought to check that. Posts like this are what make these boards so valuable.
