Gruppe-S, Full Function Technology, Vishnu Performance Systems, Dyno4mance and Turbotrix are happy to announce a special service offer for anyone who has been "road tuned."

The purpose of this joint venture is to provide the EVO community with quantifiable data regarding the performance of their "road tuned" vehicle. For a nominal fee of $25, the company of your chosing will dyno test your EVO. Among the logged variables will be Wheel HP, Wheel Torque, Air/Fuel Ratio and Boost Pressure. This information will be provided to ther user as well as become the property of the company.

All five AWD dynos have been proven to provide repeatible numbers. All five dynos have proficient operators. For additional verification purposes, it is also encouraged to test the vehicle at more than one location.

Note: This offer only applies to vehicles that have been "road tuned".

 

I was recently road tuned by Al and would like to take you guys up on that offer (I have a free dyno from Gruppe-S from winning the dyno day back in November 19th but would rather pay since I'll be adding a couple more things to the car in the coming weeks).

The only issue is I have tweaked Al's AFR and SMC alky injection settings, but I can easily zero everything out on the S-AFC II, reposition the dials on the SMC to the original settings, and turn down boost to where Al left it for the dyno. I took pictures of where the arrows were pointing at on the SMC controller and I remember what the boost was set at on my Blitz SBC-iD.

Here is my experience with the road tune:

Here is a question I had regarding turning down the max setting on the SMC in order to spray more methanol:

Some tweaking of boost the next day:

Yesterday, I turned boost up to 25 psi and the settings on the SMC to start at about 11 psi and max out at 18 psi. I fine tuned the AFR so it's from 11.0 to 11.2.

I'm happy to go to any dyno (Gruppe-S and Full Function Technology are the closest since I only live a few miles away). I'm free anytime after 3 on the weekdays and anytime on the weekends.

 

Call any one of the shops to make an appointment. We all are really excited about doing this, as it will offer some quantifiable data to examine road tuning results.

 

And Al not happy with me asking him some questions which I've seen posted publicly on the forum:
https://www.evolutionm.net/forums/sh...d.php?t=177674

Both are locked.

Actually, Blackhawk/Danville isn't too far. I would go if I don't have to drive in rush hour traffic.

 

Do whatever is convenient for ya. Any of the three shops will do For Gruppe-S, talk to Mike. For FFTEC, talk to either Sean or Jerry

Here is one of the pictures I took before changing the setting (for informational purposes so the dyno shop can compare the settings when making the runs).



I'll call one of you guys tomorrow. Thanks Shiv.

 

Just make sure you check for boost leaks first .

 

I already have. lol

 

Can we get involved?.....or is it just a 91 octane comparisons you want?
Edit: Sorry just saw it was for bay area only...

 

Of course you can join in We can make this a nice little network.

OK....$25.00 @ dyno4mance to test your road tune for expected power and torque, consitency and we will even check for boost leaks...
Evos only, Road tunes only

 

Here are some preliminary results that show Dynoflash road tunes in addition to X-flashes and Works flashes on the Gruppe-S dyno:

Dyno day results under 110 degree temp with 91 CA octane

 

It seems odd that my customers who were road tuned fared so well that day , in fact making more power in most cases than the other cars which had been tuned on dynos with local flash tuners - very odd

 

It looks like the X-flash people had cats where the Dynoflashed cars had test pipes. The top (no turbo upgraded) car had a WORKS flash. Definitely, not a fair comparision.

 

Funny indeed. Because I don't think all those XFlash guys were custom tuned.
