Why remedy it? It's all good according to Dave. Waitasec, last week Dave said it could blow your motor up:
Hmm... maybe he is just confused. So I made a little Excel spreadsheet to help him out. See attached.

The FPR is the absolute worste place to tap anything into!! Do not do that. If the boost gauge or any of the extra lines you use develop a leak you could very well blow your engine.

I just found it funny that shiv pointed out that "bigger number is leaner".

Al, you are fanboi numero uno, it must be hard to walk with that kak so far up your behind.

From the looks of it, if the car was tuned in the cold and then the lean condition happened in the heat, you could still have WG duty occuring if the Conditional is setup to modify the "User4" output to 0V. In hot temps the compensation table will still add duty to the 0V "User4" output resulting in a minor increase in boost. Whether this has an effect on the compensation is unknown to me.
If the logic of the conditional is to modify the PWM0 output regardless of what table that output is coming from, then there is absolutely nothing to worry about.

The fact that XMap displays actual A/F, and actual timing now, rather than those weird values before?
On the timing display, is that actual timing at the engine, or the timing offset from stock that the Xede is implementing?
