Low 13's a week after purchase :)
 
Track results!

60' . . . . . . . . . . . . 1.9888
1/8 ET . . . . . . . . . 8.5330
1/8 MPH . . . . . . . 83.18
1/4 ET . . . . . . . . 13.279
1/4 MPH . . . . . . . 103.90

Had the timing just a bit aggressive on that run, just a bit of knock. I will get a much better tune after I have my boost gauge and wide band O2 sensor installed.

Here is my best stock run for comparison.

60' . . . . . . . . . . . . 2.031 <- - - - - - - - - about the same.
1/8 ET . . . . . . . . . 9.0317 <- - - - - - - - - .4987 second improvement.
1/8 MPH . . . . . . . 76.54 <- - - - - - - - - - 6.64 mph improvement.
1/4 ET . . . . . . . . 14.187 <- - - - - - .908 second improvement.
1/4 MPH . . . . . . . 94.89 <- - - - - - 9.01 MPH improvement. Gained 2.37 mph in the second 1/8 mile

Dude, you where at US41 today? I saw the car but never got to see it run.

I was there pit crewing for on of my good friends in the low low 10 second ~146mph 2g on slicks. We also came out with a turbo terminator and a turbo 01 cobra.

Nice looking car.

Thanks!

Yeah, made 4 runs today at US-41. One with the stock ROM in the ECU, hit fuel cut in 5th gear and just about $hit myself! I haven't hit fuel cut in a car since my Galant VR-4 back in the day :) I tried out 3 different ROMs in the ECU and the most aggressive got me my best time, but I had a bit of knock. After I get my wide band and boost gauge I will get a crap load more agressive on the fuel tune and a touch more on the timing (about half way between the two timing maps I tried) and see what the results are. Based on the HP calculator here: http://www.dsm.org/tools/calchp.htm
along with my cars weight, and trap speeds I am making around 310 HP... (averaged between the ET and trap speed results) I was making 249 HP stock using the same calculation method.

good job...get it tuned by AMS,
since all I have is a tune and pill and it put down 13.5 @ 98.9

keep it up!

If they used ECU flash instead of ECU TEC I would. I like to tweak too much to use propriatary software ever again. I did that on my MR and I didn't have near as much fun as I had with my RS and the AEM EMS.

Keith

PS: Just learned I am only making 30 HP, not even close to 300.... but my car would still kick the $hit out of a certain sour grapes persons car :)

AMS tune will get you to 40-45. so you're not far off

LOL, I was talking about 30 HP total from my car.... at least you would think so from someone's reactions. The amazing thing to me is seeing people buy in to the idea that track times tell zero information about how much HP a car is making... if it isn't on a dyno, it didn't happen. Dyno racers make me laugh! Especially when you get them arguing about what dyno tells the "real" hp and all that non-sense. If it don't perform at the track it isn't making any useful HP.

Hell I thought we used Ecuflash? I'm just a dumb redneck technician though.

Good driving Keith. Yeah definately not 310. That is pretty difficult on the little single scroll on pump. Make sure you get the weight right in the calculator.

I think you are confused. They used to use "EcuTek" on the Evo9's before they were supported by EcuFlash IIRC. Like Jones said, they use EcuFlash now.

DAMN IT!

I asked the sales guys why it is $750 to dyno tune an EVO X instead of $395 and was told it was because of the license fee for ECU TEK...

IF the price is now $395 and you use ECU Flash you need to update the web page, and your sales staff.... this is the only reason I didn't get a custom tune from you guys.

^^^ Absolute Truth!{thumbup}

I finally got around to scanning my time slips.... my scanner does a horrible job for some reason, so I invert the colors to make the image more clear.
