Tuned a AMS 900x equipped Evo 10 on E85 yesterday.

682whp on the GST Mustang Dyno. Highest Evo power on that dyno so far.

Anyway... looks like Evo 10 ECU caps at 360 load? Is there a "uncap" like there is for the 8/9?

Code:
RPM        Load 
4769.53125        334.0625
4984.375        349.0625
5175.78125        355.9375
5390.625        359.0625
5664.0625        352.8125
6156.25                358.4375
6441.40625        360
6667.96875        360
6906.25                360.3125
7171.875        360.3125
7417.96875        360.3125
7667.96875        360.3125
7878.90625        360.3125
8066.40625        360.3125
8261.71875        360.3125
8503.90625        360.3125
8699.21875        360

as per my email (but for the information of others):

what load were you logging?

load_source( ie where the maf or map loads come from) is 2byte - meaning it can go upto 65535.

The calculation in the ECU goes like this:

Load_Raw = Load_Source * 10 / 512

So if we plug in the max value of 65535 we get:
Load_Raw = 65535 * 10 / 512
Load_Raw = 1280 (ish)

And then of course our "to english" scaling is *10/32, ie:

Load_English = Load_Raw * 10 / 32

thus Load_English = 1280 * 10 / 32
Load_English = 400

So 400 should be the max load.

Were you logging Load_Raw? or a compensated on?

Did you rescale the fuel/timing maps to higher load cells?

Even if he didn't wouldn't it show the higher load but the car would just be given the same timing / fuel as if it was scaled only to the current highest cell (i.e. 320 or 360 in this case)?
