Max APP

[Steve @ VersaTune]

What is the max APP percentage you are seeing? I've seen a lot of Gen2's that don't go to 100% More like 75% ish. What is everyone else seeing?

[EPTSpeed3]

Max Ive seen is 75% as well. Been doing alot of adjustment of tune since I learned that it only goes to 75%.

Is this a general issue? 75% sounds more like throttle position numbers, nu APP.

[Steve @ VersaTune]

I shimmed mine and got it to 83% Previously it was hitting the floor and stopping at around 75% I verified that it is getting the max travel that is mechanically possible.

None of the Gen2 logs I've seen hit 100% APP

Interestingly, it fails the Mazda IDS health check on the APP test.

Hmmm. Interesting.

So i what happens if we mess with the APP Calibration? Set 70% APP to Request 100%?

[Steve @ VersaTune]

or set the APP Req Load tables to request your max load by 75% ish.

On my gen2 CX-7, the logs shows that the minimum APP at idle is 31%, and the maximum APP at WOT is 76%!?!?

Does this mean that the lower and upper parts of my "APP requested load" table are worthless?

[Steve @ VersaTune]

I'm still looking at how the real APP number is determined by the ECU. I'm surprised to see a min APP of 31% though.

[torquemaniac]

I guess the best option should be to tune with the "requested load X gear", so the APP% wont matter

Here is a log that show the APP at idle and WOT (all my log show the same patern)
