Looking much better..

On your log where you hit 11.6-7 near 5k I would richen it by .2... Then do another 2 logs back to back and see how it looks.. If its still knocking go from 7* to 8* then 9*, instead of 7* right to 9*...

I believe the reason your torque is coming on late is your timing map is 7* before and during peak load... Retarted timing spools the turbo faster, so if you gradually went from 3* or so to 7* it would spool your turbo faster, but at the expense of some torque I would believe

You will probably need more than 28 psi to spin the tires... from a roll at least. Im making ~400/400 at 30 psi and my car just spools and goes lol. From a stop though it will leave 4 nice big black marks for about 30' though

Still waiting on JOT to let me know where this Ignition trim Vs Air Temp table is located. Wonder if its only in the Evo9 ROMs

It's in the evo 8 Roms as well but I am not an ecu disassembler but I'm sure if you made a thread asking for someone to locate that table for you, they'd hook you up rather quickly.

Sure I do that right now. I know the JDM Evo7 is not very popular

Here's my new power update. I turned up 1 psi (26psi) and made some AFR and timing changes. Car seems to like mid 11s AFRs even with the 50/50 water meth. I know the power defintely came from the cool Air Temps at night

Your peak torque is still insanely late. People don't realize that when adding meth to the mix that ideal AFR is actually richer than pump gas. Used in conjunction with the cooling properties of the water mix allows you to basically still run the same AFR's as ou would with pump gas. I don't know why people think it's wise to run a lot leaner AFR's when running that combo but it doesn't make any significant gains anyhow.

Peak torque does come on late.. I wish I could pull up a recent log of mine.. Pretty sure I hit peak torque before 4k or so

I put 2 turns of preload on the WGA. Ill see if that helps. Can it be the Buschur Race intercooler's pressure drop?
