Also, are you sure your datalogger timing readings are correct? Is it able to log any knock induced timingh retard? That, togther with the map trace, will give you a good idea as to what is going on.

Timing is pulled via OBDII into Logworks. I'm not aware of any way to log conditions that affect timing.

Doesn't map trace only operate in real time? That's what I seem to recall... without a co-pilot, not sure I can do much about monitoring if it can't capture the data.

How about some octane to see if it consistently increases your logged timing ;) If it does, you are getting timing pull from knock. If it doesn't, then that is not the case... If your timing values from the logger are correct, then I think it's obvious that you are getting timing pull (compare your timing tables to your logs by RPM/load, and if they are lower, obviously they are logging incorrectly or are being pulled down by knock).

Yeah. :(

CAM2 100octane is $9 a gallon. I'll have to bite the bullet & buy a few gallons once my tank is closer to empty.

Tried a different map from a friend.. unfortunately, it runs super rich..

..so for now, I've gone back to mine, just played with the upper load fuel map

much better AFR's in 3rd in this pull

Timing still pulled under higher boost, bur more so in mid throttle range?

I think the whole point of the TT is that if it runs rich, you just take out some fuel in 15 seconds and try again :D

Yes, indeed!

I didn't have much time yesterday, so it was easier just to switch back. I'll have another bash with that one later :D

Revised my SSI-4 wiring today - added the TPS signal. I've been using the OBDII for that, but for some reason, it begins @ 9.8%, and never goes over 85.5%, so I figured I'd try tapping into the line I already ran from the TPS to the APexi AVC-R.

... this way, I can get Timing, MAF & road speed from the OT-1, which only likes three or less channels with ME4.4 (ISO 9141 protocol)

Still waiting for a good ECU from TT - so I can get back to tuning. Hopefully I'll be back in business within two weeks.

Does your Apexi show properly?! Mine shows 0% when there is no throttle, but shows 97% when i click the WOT switch.

It shows 0% @ idle (.5v), I haven't looked at it when I'm WOT - I'll have to check. The main point is that I can adjust the scale in Logworks.

In VEMS, my throttle position at rest is 10%... Even if I re-calibrate it. WOT is right, but it starts at 10 and I'm not really sure why. You'd think with a fresh calibration that it would read 0 and 100 in the right places.
