This is some pretty impressive stuff.

Our EVO X has had a "jerky" feeling to it since new. It hasn't accelerated smoothly since we got it. I felt from the beginning it felt like constant knock correction. As the car gets hotter this problem gets worse and the power drops and get's more choppy.

Last week we ran the car with all of our parts we are currently making on it (except the lightweight battery kit). The car ran 12.70 at 111.4 mph.

Below I am going to post two dyno graphs from the day before we went to the track. You will see in these two comparisons what a HUGE difference the reflash has made. The boost levels on all runs were 23-24 psi, which is right before fuel cut with the stock ECU.

The first thing I noticed with the reflashed ECU was the car actually accelerates PERFECTLY smooth now, no jerking, this alone was a huge improvement.

This first dyno sheet is showing the car in it's smoothest form with the stock flash, this would be after 1-2 dyno pulls, pretty nice curve considering the AFR's being as rich as they are. They are compared to the EXACT same set up except with the car reflashed.

This baseline, #1, is how the car was when it ran the 12.70 at 111.4 mph. Here is the dyno sheet comparison:



Now this next sheet shows what would happen after multiple runs with the car getting warmer. As you can see the curve gets extremely choppy and looks like hell. You can feel this after driving the car hard for quite awhile too, like last week on the road course.

Keep in mind that the #2 run on both of these dyno sheets is after multiple full throttle pulls on the dyno (about 5 runs) which is when the car would start to "fall apart" before the reflash.

Here's the choppy dyno sheet vs. the tuned dyno sheet:



Peak power is up 25 whp and 39 ft lbs of torque on the smooth chart. Gains at 5700 in HP are as much as 35 whp. If you compare the chart when the car gets hot to the tuned chart there are gains as high as 80 whp in the bad spots.

I can definetely feel the difference in the tuning up top but the mid range and smoothness is the largest improvement. It is a completely different feel now.

We'll get it back to the track this week again and see how it does.

BTW, this car still has not had ANY race gas added to it at all, ever. Right now it is a mixture of 93 from various gas stations. I plan to keep it this way and see what we can get the car to run just on pump gas.

 

These are excellent results.

is this car 5 speed or what? 12.7@111 seems like you got a bad start.
(curious about how this car launches)

shoot i wish i lived by you guys i think you could use a race driver (no offense to current, i just have confidence).

anyways looks cool, i think this is the first track time ive seen from a X. how is this doing compared to others?

 

sweet, although what I'm wondering is why shiv got about 75 hp from the procede on a mustang dyno just like yours from just a tune, and a tune that doens't even have as much control as ecutek. Granted, I know that he also used a low reading base pull from before the car was broken in and then a high pull frm after the car was broken in, but everyone has done that as well. Any thoughts? Btw, I think you guys are doing a great job and I'm not trying to take away from your work, just trying to unerstand why the difference in power is so different from your results compared to shiv's. 75 compared to 35 is huge. Hmmm...?

 

shiv increased boost + tuned it. this is just from a tune

 

It is impressive to see the gains available with Buschur Flash (Ecutek based) from tuning alone. The Buschur package with the exhuast hits a lot harder than ours with the stock exhuast.

I am very excited to see how the "X" tuning is progressing.

I have been in touch with Ecutek today and they are working double time on the CEL issue which is remaining. Once that is resolved we will be ready to release the product to the public. I would say that we are about a week or two out for final release after the testing.

I am very happy to see the dyno sheet above.

The comparison above is the same mods - same car - same BOOST - A - B stock mapping vs. through the mail Buschur Flash for Stage III Buschur Evo X package

you have to remember the 25-25 whp is on TOP of the intake and exhaust mods. this is the same as adding an intake on the vishu car. with the afr dialed in on the procede, the intake wont make as much as on the stock car where it has a lot to improve upon.

 

This car dyno'd and flashed is stock right?? just making sure

 

Its not that they need a driver, they need a clutch that can stand the beating of a nice launch.

 

^^ACT has one available.

 

no, reread the 1st post. it has all the buschur mods except the battery kit. 277 whp stock? i wish

 

The gains look great but your numbers look low???

Cost for the flash?

 

Wow, it's hard to read these responses......

First off, evorecordsetter, no offense but I will bet your EVO and the money to make up the difference for my car, against mine that you can't outdrive Trent, the driver of this car and my RS. Bring your EVO if you'd like the challenge for titles of the cars. The car has a stock clutch and weighs 3500+ pounds.

Next, for the last time, Shiv's tune also added boost to the car. Adding boost alone gained 60 whp on this car. The boost was already turned up on this car, this is fuel/timing tuning only for these gains.

The reflash with the Ecutek license and including overnight shipping back to you will be determined a little later. Our numbers are low, our dyno doesn't read redilulous numbers. It just ran the highest MPH of any EVO X to date at 111.4 and only made 280'ish, that should tell you something.

BTW, we do not sell, recommend or use ACT products. I'll wait for Exedy.

 

know i wanna see a pink slip
good job guys
mr.buschur do you think the evo x on pump gas will hit the 400whp on a dynojet?
thanks
