post your maps here

It pretty much look like at 14psi the car with that map was running 8 degrees of timing and when the car got to 20psi it was still running 8 degrees of timing, So it did not drop timing per psi of boost. Transitions from 1 load column to another were not smooth as there was no interpolation between columns.
after what I've learned in the last few weeks messing around with the EVOScan software and log reader I would NEVER put a generic 'base map' in my car. I honestly can't believe we don't here more stories of people blowing up. The only thing I can think of is either we have one hell of a strong engine from the factory or our knock protection in the stock ECU is excellent... come to think of it I'll bet its a combination of both.

Also, he has a reason for doing the high and low octane maps the same, and he was just backing that reasoning up. you see, with Al's flashes, his tune is safe enough that it will never switch to the low octane. when i put my WB with his flash on, the a/f numbers hit a max of 11.2 and was mostly at 10.5, and this was after adding a FMIC without updaing the tune.
i personally set both maps the same since i want to get the max performance all the time and i dont want to reset my battery every time i hit the track. the knock sensor does a good job, and i will leave it at that.
I remember reading (forgot where) before that it takes about 500 miles for the ecu to switch from the low octane to the high octane maps. But i know for sure that in the subies, they stay stuck in the low octane map, even when no knock is experienced for a long time. i dont want to experience the "oh my car is fast today"

I've seen my tune from tuner "A" and I must say it is not good. Since we can't post up maps for review, I guess I will figure another avenue of sharing.

There is already a website that has a library of ECUFlash maps.
Right now there is basically no EVO maps, but they have a vast librabry of Subaru maps.
We should start posting EVO maps there. You have to register to see/download/add maps.

Joined I wont post the map thats in my car now cause its not fair to Al to do so also upon buying it from him I agreed that I wouldnt. Im gonna do some loging and tweaking then Ill post it up.

You want to have smooth timing maps not big jumps. Also as a rule of thumb you are suppose to retard timing per psi of boost and then add back if the car likes it, which you will be able to tell on the dyno. Not just throw a bunch of the same number in 1 big portion of the boost map. It would be noticable if there was a way to show a 3d graph of ignition timing. Each to his own though.

I think so too. The min. timing I have in my table is 3, and that is in one cell. the other lowest is 8. It runs on 93, but I really think 2 oct. points shouldnt make you use~5 deg. less. 5 deg is a noticeable change in power. very noticeable.
