Let's see your fully tuned timing maps
and a n00b quest, why are in evo 9 edm stock rom 3 high and low octane timing map ? I did a log and seems like using only one how it should. also in tehpra v7 edm rom has only 1 timing map.

Your timing looks pretty good. It can use a little smoothing here and there, but over all....you are doung well.
What about your AFR?
As for the question about 3 timing maps...They were discoverd to basically be the same thing just called for by different parameters (if my memory suits me well). Thus, all are usually made to be the same. V7 eliminated this by making the maps the same in the background (saves some work). At least I believe that is what is was all about.

Its been a while but I can't remember if the 3 maps had anything to do with the three ACD settings (gravel,Tarmac,snow). I could be 200% wrong though lol, it's been a while since we didn't have tephra mods haha.
I suppose my timing maps is probably never going to be "fully tuned", but here is one from today.

ill post my revised timing chart when i go home
Quote from Merlin's tuning guide:
The Evo7 and Evo8 have one high octane ignition map while the Evo9 has 4 high octane ignition maps. Map #1 is used when the engine temperature is below 149ºF. Map #2 is used as the normal ignition map engine warmed-up and no fault conditions. Map #3 is used in the event of a major sensor fault for example a MAF failure. Map #4 has more cruise timing and a block or retarded timing, its use is currently unknown.

Okay, so by the V7 tuning an Evo 9 only by 1 timing map is much simple
To gain a little low end torque, richen the mixture a little bit more from just after about 5-7psi boost until peak load. (like 11.3 or so). The added fuel gives a little longer and cooler burn that helps torque.
Back on topic TIMING....cough, cough.
On 100 octane fuel you have a little room to go a little bit leaner up top. Try to hold mid 11s from peak load to top rpm.

thank you, will try it !

evo IX FPred 64mm, gsc s1, 50/50 meth work in progress
thats just my number 08 ROM uploaded in my car.
Stock block.
GSC S1
FP red 64MM
Works Exhaust.
Injen Pipes
Greddy intercooler
AEM W/M Injection Kit. (boost juice 50/50)
11 psi actuator. 28.5 29 psi peak and tapering to 26 psi
im steel working on the map... Methanol is the best choice for de crappy Fuel of my country...
im still smothing my AFR and giving more timing
any recomendation ?

Yes more timing and maybe more boost or just more boost maybe. What octane fuel?
21-22 psi tapering to 19.5tephra v7, ix turbo, hks 280 cams. pte 1200cc, full exh. fp intake pipe, ams balance shaft delete, muse uicp, xs pwr fmic, xspwr licp grimmspeed 3 port 93 oct gas
If I try to do a log starting from 2500 rpm or even 3000 rpm I get knock right away cant figure it out. AFR is around 11.7 tapering to 11.3.
p.s. this is not a english racing tune. getting a english racing tune if I can not figure out knock by myself.
