Stock FR-S Tune Just Done
As the title says, I brought my FR-S down to HG Motorsports in Sorrento Valley, CA this past Saturday to get a baseline dyno run and have the car tuned on all stock parts. The tuner is William or Bill Knowes, who happened to be lead tuner at Crawford for almost 8 years and personally tuned many of their famous cars such as those from Gymkhana 1 & 2.
Anyways, the dyno used was a very very old Dyno Dynamics, which according to Bill, is the heartbreaker of all heartbreakers. I have all the dyno printouts, and will be posting them sometime tomorrow for all to see. For now, what I can tell you is that everything about the car is far better. Smoother in all gears, steady and stable idle, and last but not least, power. The average of 3 base pulls was 138.7whp at peak or so before the tune, and around 152.8whp peak after. At redline, I picked up 30whp. Instead of just dropping off at 5-5.5k like it did before, the car just keeps pulling and pulling. I know, I know, this thread is useless without pics. Pics or it didn't happen. I will post all the dyno sheets tomorrow. Keep in mind that on a Dynojet, I'm guessing I would be around 175-180. Dynapacks read even higher. PICS TUESDAY the 5th! |

http://i50.tinypic.com/ndnw1.jpg ^These are my car, before and after stock tune. Pink is before, green is after. All averages of 3 pulls. http://i49.tinypic.com/2hprj2w.jpg http://i46.tinypic.com/b5fn8k.jpg ^ These are my car after tune (green) versus a stock FR-S that belongs to someone else on these forums. This is significant because the FR-S represented with the grey curve was one of the first to hit U.S. shores and was clearly tuned a bit differently from the factory. The grey line is NO TUNE. Aside - Yes I know it may say Flywheel HP, ignore it. It's WHP, and it's reading low because it's an older model Dyno Dynamics, as stated above. Deal with it. |
Also, I apologize profusely for these being sideways, but I don't feel like putting in more effort so go ahead and snap your necks to read the graphs. :)

All stock parts with a gain of 30whp? Really? Wow! What on earth was done to get results like that?
|
I'm not sure exactly, but of course when he was doing the pulls the graphs were made live and also had an AFR curve in there. I noticed that around the top where there was a 30whp gain, the AFR got so rich that is flatlined because the 02 sensor couldn't read any richer (before tune). I know he dialed it way back. I'll have to ask for a before an after for AFR too because the before looked like someone having a heart attack and after the curve looked stable and not too rich or lean. :)

What tuning solution did they use?

Any idea what had been causing it to run so poor? Rubbish fuel maybe? |
I may have to give him a visit.

Fixed.
You're welcome :) |
That's very impressive all stock gains. Perhaps you had a faulty sensor and its reading got tuned out? Otherwise why would this car be drowning itself in fuel up near redline? The O2 sensor should have been shouting shut the f***ing fuel off to the ECU lol
Either way that's stellar performance my man. |
Looks good, a tune really unlock the potential, Theres probably some discrepancy in the first stock run, its really low. After a tune i expect our cars to be in the 160-175whp range depending on the fuel and aftermarket parts. 200whp for e85.

nice gains~!
