I'm running an Evo 8 Ecu on my 97 Eagle Talon. I recently got around to properly scaling the MAF (2g DSM) but I'm having 1 problem; I need a 350Hz row. The AFR are fine at 302 and 403 hz, but it goes lean (some times as much as 1.2 AFR) in between. This also happens to be the same hz area I'm in when I go from crusising into boost. I think this may be the reason I'm knocking.



I need to know what other tables may be messed up if I removed my 25Hz row and added a 350Hz.

From this:


To this:


From what I've found, the only other map that changes is the MAF Compensation table.

I know my scalings seem really off, even compared to other 2gs running an Evo 8 Ecu, but it makes my map AFR match my actual AFR and 0psi = 100 load.

 

On 96530006, both "Airflow/Hz Raw Scaling"/"MAF Scaling" (at address 3306) and "MAF Compensation" (at 3322) use the "MAF Hz" axis (at 67a0). That should be it.

 

Ok. That's all that I've seen too.

Thanks.

 

Make sure you have lean spool disabled. This doesn't look like it is enabled, but it could be a contributor.

 

I disabled it by setting the start and stop points both to 2500RPM. Maybe I'll try something higher, just in case that's still messing with it.
I don't have it disabled in the periphery bits because there was some debate going on about that.

You may also find this post I just made on DSMTuners interesting.

Not exactly related to this, but still something.

 

Why not just use periphery to disable lean spool?

 

I'm not sure why I haven't, actually.

I'm going to try messing with it more tonight. I had to much homework the last 2 nights to even mess with it (pulled an all-nighter last night.)
