Lightbulb Won't take timing up top Help!!

I've compare my timing map with many other tuned evo and my timing is much less up top.

I know every car is different, but I want to make sure this is normal.

Boost leak test was done prior to the tune.


EVO8 6 sp
HKS 274/278 cams
HKS 7460R turbo
850cc injector
Full TBE
ETS IC
tephra V7 94170715
Grimmspeed 3 port solenoid
JDM map sensor
255 fuel pump

Are you not running more then 240 load?

You load curve would be helpful. Without that we can only guess you are either running pretty normal timing (240load and below) or horrible timing (260 and above)

We just want to know how much load you are seeing throughout a pull so we know what cells you're hitting. Post a log or a maptrace.

How much boost are you running at high rpms? That plays into the equation as well.

Dude if you don't already know where to find you load curve then you shouldn't be tuning your own car yet.

FYI you should be logging load when you datalog the car, there are a few different loads you can look at there is Loadcalc, 1byteload, 2byteload etc etc

Post up your evoscan datalog file and we can help you

Do you have a wideband? What AFR are you at after spool up to redline.

How much boost are you running?

What type of gasoline (reg, premium, e85, racegas etc etc)????
