Yea, I used the 89970010 ROM to do the comparison for 89970017. The map addresses are the same up to the scalings; check it out in hex/DEC.
The base is EVO9 (unsure whether the Tomei ECU was read/open using EVO 9 kernel?)
They needed to use EVO 9 read method to pull the ROM from their vehicle.
Target AFR is 14.0 (not the normal 14.7)?
Maybe to keep the engine cooler at idle and cruise speeds or they are tuning in for some sort of injector/fuel system upgrade/anomaly by setting the “target” to 14.0. Just because it is set to 14.7/14.0 does not mean it WILL run 14.7/14.0. This looks to me, to be a closed loop tune.
Max wastegate duty at 127.5% (max is 100%)?
I “THINK” Tomei is tuning a different turbo that has 27.5% more potential than the stock setup. I do not know the setup of the Airtrek and only have the service manual for the Outlander XLS. In the world of mathematics, 127% makes sense and may apply to this. But overall am unsure of this.
edit- Found the right map, and only #1 map is tune-able.
Timing data are totally crazy?
Tell me about it. Don’t have an answer to why it is so aggressive with all maps set the same to defeat knock related/map switching.
I posted in General Discussion about this map setup. I think it is a very easy way to get around false knock/anomaly related Ignition Map switches. I overall feel the tune that Tomei applied is based off factory output, and the changes should reflect the upgrades they might have made.
I was interested in the MAF settings being very close to my Galants, and have been particularly interested in this particular ROM/Engine setup. So keep me posted if you find anything out. I will look into the ROMs ability to changed to an EVO 7-8 flash as soon as I get some quite time this week, but all those questions you asked have been itching my brain also…
