but I would still like to know, dbtk2, what the true effects are using it on the SSEi.

And that I will try to figure out for you. If you want to see results in certain driving conditions I can do those also. Let me know how you want the test done and I will see what I can do. (i.e., do you want 0-100mph runs, 20-50mph, or anything like that) If you don't care I will do just like 0-100mph runs.

I am really interested to know if it causes Knock retard and defeats the intension of increasing timing in hot weather.
It will not be something I do in cooler weather.
It would also be nice to prove how long it takes the PCM to learn to ignore the trick.
Thanks

0-100 mph. That sounds sweet.

The main things I am going to be scanning are O2'*, Air-Fuel Ratio, Air Intake Temp, Timing Advance, KR, Speed, RPM'*, Throttle Position, Current Gear, and I guess I can calculate boost too, although I can't see it making a difference in that. I can't think of anything else that would make sense to scan. I can always just throw in coolant temperature and tranny temps too.
I just remembered I may not be able to scan for a week or so because the Mini-AFC on the SSEi is broken so it will be running really lean, and WOT runs and lean conditions don't mix. Unless I can borrow the one off the GTP it may be a week or so, besides the fact that I am going to want to get some time to review the data anyways. The date I am going to shoot for to have it all done is August 4, so look for data on that day, the post should be up by then. I may be able to do some of my Traction control testing also to get some more info on that, but that isn't quite as easy.

For anyone else considering this mod, if you INSIST on doing it, don't buy the crap off of ebay. Buy a resistor and do it yourself, but I'd suggest buying a scantool first. You'll need it, or you won't know what'* going on.

I would wait until version 2.0 comes out before buying one though, it looks as though that one may be much better.
