AEM EMS Banter Thread

[J. Fast]

Here's a few timing maps recently posted up I transferred to AEM... Plus some

My current twin 20G EMS timing map optimized on a dyno



Surge fix dyno optimized timing map for pumpgas TD-04 turbos boosting up to 200KPA



Stock ignition, twin turbo, high octane timing map translated from 99 Chrome ECU



kylightning's high octane timing map on DR750's with methanol injection



My personal dyno optimized and smoothed stock timing map.



I like the smooth ones. They pull real linear.

Wow, that is a pretty interesting map for surge fix. Was that created at elevation?

It started at elevation. In 2010 I drove across the US from Denver to Maryland. I stopped at 4 dynos on my 5,000 mile roadtrip. I kept optimizing to resolve the tune as the air density changed. This final revision was developed at my last stop on the trip. I worked with J. Rhodes at ET Tuning in Union, Missouri until we resolved the surge problems on my 19t setup at the time. Took about three hours to figure it out but we got it.

I never got around to trying the timing map, but I would love to hear your feedback. Be mindful of the RPM points though, if yours are different that it wouldn't be as easy as copy/paste.

Well i tried this map today as the weather gave me a chance to do so , car started ok but would not rev up , very hesitant.. may be due to the fact i only had chance to change the ignition map and no time to mess around with the fuel map , but no joy at all with this .....
Merry Christmas to you all ...

Do you know how to log? If so, send me one along with your .cal.

Sorry it didn't help your situation. Maybe FamilyMan can help you.

Hi
I have AEMdata which i use to log , what i will do is put my old cal back in then i can go for a run and save a log will not be for a few days now though i will upload them and send a link (if i can find somewhere to upload it to)
Many thanks

Just email them to me. I sent you me email address.

Sent you some thoughts, concerns, and ideas.

edit: Just looked at Jfasts td04 timing map. That will give you an idea of what I was talking about. You are almost running anti-lag with timing almost half what his is at 2000rpm As suggested, please make sure your timing is synced before doing anything and calibrate the TPS. Then add timing but don't jump straight to j's. Start less and see how it reacts. (j tunes a lot of modifier tables, so his actual timing may be much less than his posted map so don't cheat and copy.) Then fine tune your fueling.

let's see the timing map...
