I plan on just fixing the problem. The gearing on this car angered me from day one. I just hate to rebuild a tranny with only 8k problem free miles on it.

The best I could get at the 7800rpm limit was a 114.
Thats very impressive! I can get more than 113mph on my runs and I have a little more power on the dyno. How did you managed to get to 116 by just upping the rev limiter??

All of my times were within a tenth of a second. I needed the extra RPMs in fourth to pull that mph. I was bouncing off the rev limiter at 7800 and just nudged it at 8000.

EVO 8 ignition map 21 psi 93 Pump

Here the map I pulled off the car I just bought. Previous owners tune. I did add the lower timing cells for the 2 step. Otherwise untouched by me.

OPINIONS? Car has 272/264 cams, tbe, fmic, licp, cai, 10.5 hs, ebc, 1g bov, 255 pump, prob missed some but that is the jest of it.

^^ How much boost? You might be able to get away with a tad more timing between 25-4500rpms. Look pretty safe depending on boost/afrs, have you logged it?

How are able to run so much peak timing? What AFR's are seen with those of you running 13+ degrees of peak timing? I assume the changes made are between 7000-8000 and the 220 and 240 load cells right?

The 8's can run more timing up top compared to the 9's.

But I still see many IX owners, in this thread alone, running 12-13* of peak timing; is there a particular area where the IX or evo in general will see good results of running higher peak timing? Particularly the 7K and 7500K RPM point at the 220 and 240 load cells is my question, I'm running 11* peek with 11.3 afr's,

You are running 91 oct in texas right? Here in California running our crap 91, 10-11* at 7-7.5k on the 9's is the sweet spot, depending on mods, etc

No, I'm on 93 octane...based on my mods and afr, is it safe to say that in the load cells 220 and 240 in the 7K-7.5K points 12-13* ought to safe? I know this is all relative, until I go out and log what the car is doing...The car feels strong as hell right now, but if I can up the timing up top, I'm sure it'll feel even stronger with higher peak numbers...

Depends on what the car likes. I would imagine with a MBC you can run a little more timing up top than ecu-boost that holds boost well. You won't know until you log and tweak.

Also, at this point I'm not knocking after 7K at all, would 1 degree of timing induce lets say 10+ counts of knock or would it induce more subtle knock? I know theres no way of telling, but is there some sort of general rule of thumb?

The general rule of thumb I follow is 1 degree is 2-3 counts of knock. At least thats the way it is in the DSM world, after much tuning and playing around I found this to be the same in the EVO ECU.
