Speed Density tuning an EVO8 w/dyno sheets
Speed Density tuning an EVO8 w/dyno sheets
We had a customer, EVO8LTW, bring his EVO8 in for some work. The car was dropped off for a number of things, drop in pistons/rods, cams etc.
The car is equipped with our drop in pistons/rods, BF272 cams, Race FMIC, upper/lower i/c pipe, HKS DLI2 ignition, 3" turbo back, FP Red and more. That is the basics of the build.
The unusual part of the build was the stock ECU being converted to speed density. Rich, the owner, had the car pretty dialed in when it was dropped off and gave me a few pages of notes
It made my job pretty darn easy. I wasn't sure what to expect and had been hesitant to even want to get started on it. Truth is, the tune went smoothly and was one of the easier cars I've had to tune.
The car is running straight 93 octane fuel from Shell and was tuned at 31.6 psi of boost with the stock knock tables set up. The power it made is up there with the highest numbers we've seen on a Red on our dyno on just pump gas.
Here is the graph in 3rd gear:
This one is 4th gear and you can see there was some compressor surge down low which put the flat spot in the tq/whp, still excellent power:

At this power level this car can easily run in the 10's just the way it sits with close to 130 MPH trap speeds.
The car is set up for road racing and should be a killer combination for that. Very nicely put together car, nice cage in it although it was a bit cramped for me.
Enjoy your car Rich, it's going to impress you I think

This thread is cross posted in the dyno results section. I'll just copy my response here too since I really do want to give credit to the folks on this forum. Thank you so much!
Wow!!! I had high hopes, but I didn’t think it would make that sort of power on the stock ECU and 93 octane! Holy cow!
Thanks so much to everyone at Buschur, from Nick Ryan who made the whole ordering and scheduling process painless, to Daniel for wrenching on the car, to David for tuning the car, answering my questions and generally being patient with a really picky, difficult customer. David has been extremely responsive to emails and PMs, he read my “memos,” and he took on a new challenge with the SD tune. I was happy with BR before I even got the dyno results!
I’d also like to thank the amazing folks on the EcuFlash forum who generously share their developments and knowledge of the stock ECU daily with others for little to no compensation. In particular, tephra, mrfred, jcsbanks, and l2r99gst’s posts, threads, and developments have helped me out tremendously with tricking out the stock ECU and converting to SD. A few years ago, I bought an AEM EMS but I sold it before installing it when I started to appreciate what the stock ECU could do. No regrets!
Thanks again to all! Can’t wait to get the car back!

Yes agreed, I said thanks to you, Rich for having the car close when you brought it but I also owe a lot of thanks and try to remember to say it quite frequently the guys who put the hard work in on all this stuff. THANK YOU GUYS.
Dave, nice work and awesome numbers. Nice to see a stock ECU SD tune on your dyno and making great power.
EVO8LTW - very nice setup...very similar to what I may eventually get to. Congrats on the great numbers. Can't go wrong with having David and the team working on your car. Maybe try it out on E85 now to see what it can do compared to 93?
