[QUOTE=-=SPECTRE=-]The verdict is in. After comparing all the tables of the 13-15 ROMs they're almost completely identical. There was one field that ECUFlash could not read on the version 13 ROM - but it did return a value on the version 14 and 15 ROMs and they were identical. The field that could not be read for the version 13 ROM was Injector Size Scaling..
Hey thanks for doing all this work. Great job.

looks like the first mod on the evo9 should be a boost controller.

It could be a slight Boost leak in the IC piping with is terrible for the Evo. My stock Evo VIII would NEVER get past 15PSI of boost, even a WOT dump would net me 15 PSI. I went to town on the IC clamps and BLAMO, 19psi.
I sugget anyone haveing a boost issue on a STOCK Boost shoudl try this, it picked my up 4psi and the car was MUCH faster.
I think the 1st mods should atleast include IC piping and T-Bolt Clamps.

yup, my new MR would not boost higher than 1.3 bar and neither would my buddie's who bought it from the same place, I thought it was due to the heat since it gets hotter than hell down here Vegas.

I datalogged the 13 map today and it works fine - I'm staying with this map on my car until I need injector scaling, then I'll go to 14 or 15. I am pretty sure with this map I'm seeing closer to 1.4 bar.
