I just got back from Mynes performance in Mesa, AZ after a dyno tune. I have a 05 MCSc, 6 speed. My base power was 192.3 whp @6750. My base torque was 157.2 @4500. I currently have a 15% pulley, CAI, Oneball exhaust and Megan headers with the test pipe. Anyways, after tuning, my test power was 210 whp @7500 and my test torque was 167 @4000. Pretty good results for a mod that didn't even require a screwdriver!
Jason is the man!!!

 

Good job .

 

congratz on the #'s..btw it mynes..

 

I'm a bonehead! MYNES Performance!

 

What sort of costs did that entail? I am in PHX and that sounds like pretty promising gains!

Thanks

 

I paid $500 for the tune. That included the dyno time as well. You can really feel the extra power in the upper range. I highly recommend it.

 

congrats you have the strongest NON cylinder head Mini in the world

 

Can someone explain to me why software changes give power increases? What sort of sacrifices are being made? Things always balance out... A gain somewhere is a loss some where else... Reliability issues? Idle issues? Gas mileage changes? I have a 15% and a CAI. I have been told by very reliable sources that an ECU change really won't add much.

 

I don't know if this was a sarcastic remark or not but Jason at Mynes performance is a reputable tuner. I believe he tunes Isellems mini and tuned/ and helped develop the Fireball cars. Anyways, you don't agree with these numbers?

 

I thought it was perfectly clear what I wrote.

 

That is an impressive power increase, but more impressive was the torque increase, which is at 500 rpm lower than before. Does the dyno graph indicate what the horsepower was at 6750 rpm? If so, mind stating what it was?

Did you have air/fuel ratios plotted? If so, what were they before and after say at 5500 rpm on?

Were the ambient conditions almost the same for both dyno tests?

 

Daaayum, 210 and 167 is nice.

That was my question too SteveS. What was the whp at 6750RPM after the tune? Obviously they raised the rev limiter to get you to 7,500 after the tune and some more peak power, but it would be interesting to see the comparison at the lower RPMs, before and after tune. I don't think I'd want to be running my MCS at 7,500 too often

When we did our club Dyno day at Mynes last year they sent us all a plot after the event.
Mine looked like this:

At the time an 05 MCS with 15% pulley and DDM CAI, everything else stock.

Very impressive place, and Justin definitely has a solid reputation.

 

Please tell me how to post a picture and I will post my dyno sheet.

I had mine stored on my website, so I just pasted in the link to it on my previous post. But here it is attached as I described.

 

I gained a ton from my custom tune and I now know my car runs safe. Most of the time SOFTWARE tunes don't do much for N/A car but it works wonders on supercharged and turbo motors.

ChaChaCha, I'm glad you are happy with your tune, the important part is that the car feels better and you know the air/fuels are safe. I had to learn the hard way, on going too lean.

your air fuels can be safe as safe is... if the car is being run too hard and heat builds up cause of improper cooling from mods you add after tuning etc etc you are going to loose the motor... so cha cha cha... watch out in the summer time... it's gets hot out there.... more over... CONGRATS!

 

Here is the dyno sheet.

 

Very nice, but you lose quite bit of low end torque. How does it feel below 4,000 rpm?

 

You feel almost all of the improvements in the upper range. I only felt a slight improvement in the lower range, but definitely not a loss. As you can see by the graph, it was no slouch before the tune, but now it is crazy fast between 6500-7500. You can really feel the difference.

 

Wow, very flat torque curve. Both before and after.

Would love to see how she performs at the track.

 

Dangggggg, looks like I need a custom tune...to bad I don't think anyone near me does tunes!

-Cody

 

yep.. and since its a four banger.. if your below 4k... you arent driving right!

I don;t see a loss in low end am I missing something?

 

No, I just mixed up the green & the blue lines. I thought I was seeing 50ft/lb difference. Time for bed.

 

 

like counting marbles, where if you start with 10, no matter what pocket you put them in, you still have 10. Factory tunes are pretty bad for peak performance. There are lots of reasons why. I'd also guess that the very reliable sorce doen't have the "keys to the castle" so to speak when it comes to tuning the MINI ecu. If you look at the history of tunes on the car, they started with some mid range, but not tons of HP increases. Now as the hackers are getting deeper into the ECU, they are finding more to give benefit. I think my first ECU tune was very early MTH about 4 years ago (I think). Drivablity sure, but not a lot of power. But look at the posts now for power. Heck, there was even some who on the way to finding the right keys, changed tables that adaptation drove back to stock. Also, there's more to change than just WOT fuel and timing stuff. As far as I know, MTH is the only one offering traction control mods. Don't know if the DimSport crew has the keys to this particular room of the castle either! With each tool set, and operator, there are different things that can and are changed in the programming.

Not all ECU tunes are created equal.
