Is the A01G E85 tune on the first post for MT, AT or both?

NM just realised all G roms are MT

[alamando]

Flashed the v80 A01G E85 rom with EL AVCS tables on my stock 86

here's a 3rd gear pull
http://www.datazap.me/u/almando/oft-...om=16350-16482

rich after 3.8v but ok elsewhere? Should I use the type 2 "AT2" MAF scale?

No, don't do that.

Multiply 3.91 and above by 0.99.

That will get you close to 12.0

With headers it likely wouldn't run rich like that, so when you get headers, go back to my default MAF scale.

Awesome. Thanks Wayno

Good on your for having a go yourself. Fellow Queenslander.

Here's a pull with the MAF changes.
For some reason it is richer everywhere.
Did I not give it long enough to learn fuel trims properly?

@Wayno @steve99

I'm curious how the new values in the O2 sensor scale were determined. Not only were the values changed, the scale itself was significantly altered. I'm mostly curious about the reference scale changes.

Pretty sure @Wayno is using @ztan's scaling, which is described here:

yes as above ztan rescaled stock o2 sensor using an aftermarket widenband as the reference

You need to wait until your LTFT is under -6 in OL. Basically that whole AFR curve will go up 0.9.

You must have an extremely high E content at your station (Doonan, Hearvey Bay, Gladstone?). For my testing all year I've had LTFT of 0 +- 1 with that scale on United E85 from Bald Hills.

Thanks Wayno. Will wait till the trims improve before I do my next pull. Getting my E85 at Doonan.

Loving the power gains btw, do headers get you much more? Do you recommend EL or UEL?

See Australian dyno thread for what uel vs el looks like on oft.

below is a reasonable representation of where the differences are that was with stock tune, with tune it just all moves up maybe 10hp




another comparision here

http://blog.vittuned.com/just-a-coup...-vs-tomei-uel/

thats on USA petrol which is far better than ours. our crap petrol newters the gains you get, hence great results with E85

All right, I'm confused again.
I'm looking at the changed tables and I find the one for requested torque. The two axis are RPM and some representation of the ECU requested torque. The result in the field is the required Throttle Angle.
What has me scratching my head is the Requested Torque. There are multiple columns with the same value?!?!? Which one does the ECU use? It makes no sense to me. Can someone explain this set of values? Remember, this is not the first row of data, it's the lookup value across the top.
This isn't a change Wayno made, it's in the Openflash tune as well.
