Hello all, have a 2009 G8 that's giving me some grief and looking for some suggestions...
Here's the problem: if rolling down the road say 50mph and you go WOT, the car will start to take off, then the ETC closes for a split second, then comes right back.
I have just about every TM setting turned off, but in the log (table) you can see the ETC TqMgtType say 'Trans' when this happens.
Seems to happen only when it needs to downshift, if you manually drop to 3rd and hit it, no trouble...
Mods on the car: comp cam (224/230 114), kooks long tubes, and 3600 converter in it.
Any ideas? I've been trying a ton of TM combinations, but can't seem to get this one...
Here's the tune/log/cfg (ignore wideband - wasn't hooked up).
In the log, the problem shows itself at 2.32.756.
Thanks for any ideas!
