I understand the values change based on the torque curve or efficiency of the motor at different ranges, but how much should they change bin to bin, say, given your MAP and RPM bins are linear.

Couple things, I would check for leaks first, and then I would disconnect the feed to your wastegate. Be careful now, but see how fast boost rises.(and it will go to the moon if you don't back off by 3-4krpm) If no leaks and boost rises fast with wastegate feed disconnected, it's your home depot ...

Hi, I'm confused, why less gas? the engine just goes lean in this log, and any decel when prior to throttle shutting here is lean stumble - i just blipped the throttle here, that's it. The log does not indicate it goes rich before it goes lean if you were thinking rich misfire?


kev_rm,



Note ...

Where are you finding this limit? Is it related to EDIS-8? My EDIS 4 seems to function above 7k

I read up on scaling. Shouldn't be a factor yet. Want to get off-idle working first then deal with rich accell at higher rpm later!

EDIT: 2500/5000 is the setting.

HI lance, I linked in a screen shot of the AE page, but to answer your questions:

1) no X-Tau.
2) combination MAP/TPS due to large tb diameter. 50/50 seems to work best so far.
3) Not sure what AE rpm scaling is, sounds interesting, most of the problem is at off-idle!
4) warm
5) 40kpa/Sec, 5%/sec ...

MS-II v3 running latest beta code .684.

Can't get the off-idle AE right. Goes lean, then goes rich afterwards. tried lots of combinations. This engine has a large throttle body to displacement ratio (65mm:2.6L) and an agressive manifold.

It was a lot easier to get right with MSnE!

Would love any ...

Has anyone used an emissions shop to help tune to pass emissions? I'm wondering what are the right questions?

1) Do you have a 3-gas analyzer?
2) Will you let me help you make adjustments?

others?
