ECUFlash dyno results!
update: dyno sheets posted below
I spent one hour tuning on the dyno today and I'm very happy with the results so far. I originally wanted to make two maps, one for pump gas and one for race gas, but I wasn't able to get any unleaded race fuel yesterday so I had to stick to just straight 93 pump gas.
From start to finish today with just tuning I picked up about 45 peak whp! I started out with the stock fuel and timing maps with only fuel/boost cut removed and slowly built on those. Baseline run in my 04 EVO GSR w/ TBE, K&N panel filter, walbro & MBC @ 1.4 bar was @ 255 to the wheels peak HP and close to that in TQ. I don't have the dyno sheets in front of me, they are being emailed sometime tonight, so those numbers are going from memory. The final result 8 passes later was 297HP and 290TQ. That last pass was with just a touch more boost then the baseline, 1.45 instead of 1.4. I was only using a pocketlogger to monitor timing & coolant temps so I didn't want to push it.
But the awesome parts is those are just the peak numbers, I picked up the most power in the midrange between 3-4.5k RPM where it increase over 50+whp from the stock map! Thats smack in the middle of where I drive the car everyday so those ponies are going to be felt. Soon as I get the sheets I'll post them up. For the time being here are the final map screen shots.
one thing I learned today was that my engine likes a lot of fuel.

It's not that your engine likes alot of fuel, the target value is just that a value.
Normally fuel is measured in Milliseconds
Good job on the tune.

congrats on the gain. How much did it cost you to get on the dyno. I have the same basic mods as you with the exception of a k&n filter. I am still trying to get this flash thing working the way I want it to. At the place where you got dynoed. Did you do the tuning or did someone else help? Also to get on the dyno do you have to have a wideband still trying to get the wife to let me get one of them.. Does the dyno facilty have one on loan??

The guys at Philly Dynoworks are pretty cool and they do have a wideband there. I did the tuning myself with the ECUFlash & pocketlogger. I brought my cousin along who knows a good bit about DSM's for another set of eyes. The tuning part was pretty straight forward though.

pardon my ignorance but why would load column 300 be useful for someone running pump gas on the stock turbo? Wouldn't that equate to ~26 psi?
Further, is it safe to assume that since column 200 = 14psi and 260 = 23psi, each column in that region represents an additional 3psi of boost?

I dont think the columns pertain to boost solely. There load tables, boost is a factor however in the ECU determining the load on the engine. Some stock turbos spool real fast and make peak torque really fast, sometimes bumping them up into a higher load area. Hope that helps and Im understanding this correctly.

when I hit 1.3 bar I am near 220 load on my ignition maps
and its 14.7 psi = 1 bar = 200 kpa = approx 200% load before the ecm modifys the load % with other calculations
