I did, and it was an absolute success.

Whereas I had been reduced to using an ignition map that made things feel as though something was wrong, I reloaded the factory map values (offboost load cells) and went out for a drive. The result was a HUGE improvement with not one flash of knock, and that is to be expected being that I can now use 25 deg advance in cells where I had been reduced to 12 deg.

The car now feels like it's always rolling downhill, and I can guarantee with absolute sincerity that using an HTA82 with T4 1.06 twinscroll kicks *** in everyday driving. As soon as I get moving from a stop, this thing feels like it's taken an on-ramp to hellaciousness, with no knock CEL, and I haven't even tuned it yet!

Adjusting the low rpm knock multiplier to 19 and the mid to 22, definatly made the knock load adjustment better. Thanks jcsbanks. I've got no low load knock issues in any gears.

The wiki doesn't have 96420008 to download. All you need are the three values for the multiplier for knockbase calculation. They are probably very near to other Evo 8 addresses.

IF I sent you my ROM would you be willing to look at it? I do intermittently get low load knock but nothing horrible. But once I build the engine with forged internals soon Id rather be ready for it.

Has this fixed the low load tip in knock issue for 94170015 users? (Sorry if it's been mentioned.) I would guess it has, maybe it's time for me to try and switch out my 0008 for the 0015 (again.)

I can confirm that it has completely eliminated phantom knock in my case.

96420008:

Multipliers:
177a 13
24aa 18
21de 20

For those trying to disassemble, if you find the first value at 137a or 177a, the routine that references this address has the other two addresses called nearby. It is ultimately called from the longsub_inj 802Hz called from CMT0 interrupt (vector 2F0 in all SH2).
