Since about last Fall, I've had the Accessport. I love it, and the jump in HP you get from plugging it in it amazing. However, nobody can dispute the true value of a good custom tune...

...That said, I contacted JB, one of the owners of Performance Auto Solutions in Deer Park, NY. They tune lots of WRX's and STi's, but since the Mini is adapted to the AP system, they are able to tune Mini's as well.

Prior to tuning the car, a boost pressure check was done to check for leaks. It turned out I had a nasty boost leak in my intercooler piping. Easy fix, just tightened a few clamps. Once I was "cleared for tuning" Dave, their tuner, was able to get a beautiful tune out of the car.

Just want to give everyone at PAS a shout out, and to spread the word of another great tuner in the northeast!

Final numbers (Mustang Dyno): 207 whp, 266 wtq

Nice power! What other mods do you have on the engine?

 

Thanks Chris!

If you happen to talk to Jeff Perrin anytime, he may remember tuning my car via datalogging because I wasn't making boost (a while back). He suspected a boost leak, and there turned out to be a sizeable boost leak... lol

 

Haha, nice, I bet it feels good now!

 

What plugs are you running that are a step colder?

 

Ever get a super knock code?

I love my AP but have had to take it off due to super knocking BAD!

I have been driving it without the AP and today the weather was 104 outside and I was pushing the MINI hard and didn't get the super knock.......so it appears only when I have the AP on.

 

You can get rid of your knock two ways. Have your tuner go in a check your ingnition tables under load and reduce timing in the cells that are advanced to much or you can simply run a %20 E85 mix safely. I suggest running a E85 mix and monitor you knock to see if the alcohol works.. With the combination of the cooling effect and 100 plus octane rating of E85, direct injection cars have a octane rating of 160. Of course a 20% mix would not be as high. I ran very high boost and timing (400hp) on my direct injected mazdaspeed3. Enjoy

 

I don't have a tuner. I just bought the AP and installed the stage 1 91 octane map. I emailed Jeff at perrin and sent him some data logs. Of course the data logs didn't record the superknock. We thought it was a bad batch of gas at first. Then when the weather warmed up it came back. He suggested I take the car to the dealer since it's under warranty. I took the AP off and it cleared the ECU of any soft codes......been trying to get it to super knock. Today was 104 and I was pushing it. So far I only experienced this with the AP installed.

Pretty bummed, I ight have been better off getting a RMW tune since I lie in the area.

 

Btw, a 20% will not skew your afr to cause any sort of a lean condition to cause a check eng light. I have a gen2 and run a 20% in the summer here in Phoenix and I don't have an ap because I'm an 11'.

 

So where do you get E85 on CA? Last thing I wanted to do was spend more money on gas and have to mix it.

 

If it doesn't knock with e85, then you know you have to much timing in a particular load range during acceleration, trust me I have tuned with ap's for years. Load+timing=power. You have a timing cell or two that have to much timing at a given load range that is giving you knock. Throw some E85 in a see the knock disappear.

 

Google E85 stations in your area a put 2gal in on a full tank of 91. It's easy.. Todd

 

The Superknock code is very common, and I bet you a good majority of R56's S's have a superknock code stored if you were to scan the DME.

However, simply telling him to run some E85 to increase octane to stop knocking is just a band aid fix. Getting consistent knock with Stage 1 is not right...the maps are canned and stage 1 is very mild. I'd be willing to bet you have carbon issues and/or HPFP issues.

 

I have a 2010 with 27k miles. Can't say for sure, but I don't think I have carbon issues yet. I know these direct injection engines will get carbon buildup early on. I planned to have a walnut blasting around 45k. I sent some data logs to Jeff at Perrin performance and he said everything looks good. We data logged the fuel pressure.

All I know is, the car never super knocked while I had it, until I installed the AP. Loved the performance, but can't have it super knocking all the time. I took the AP and now I can't get it to super knock. So it only seems to happen with the AP

When I try to accelerate onto a freeway on-ramp it stutters and makes the tin sounding knock almost like a rev limiter sound!

 

Thumper, you missed the point, re read.

 

Keep in mind the so called super knock, can also be attributed to loose part/parts in the engine bay or simply be a significant bump or rocks in the road. I ran into this dataloging with mazdas.

 

LOL

I can maybe see that happening. Unfortunately that's not the case with my MINI. I get hard cut out's feels like the car is missing and I get that horrible tin kocking sound! 100% knocking. Sucks when I go to pass someone and the bastard acts like its passing a kidney stone!

When the weather is cooler I don't get it. Once it gets warm and we had a little heat wave this week with temperatures above 100. I wanted to get the superknock code again so I could take it to the dealer. Obviously I can't complain about it and take it in without the soft code being stored.

at this point I'm not 100% sure what to do. The MINI is running strong in stock form. I like the performance of the AP but not when it runs like dookie and might blow my motor.

 

PAS is the closest AP tuner to me as well, nice to see some results on a mini, i cant wait to make it over there and get a custom tune as well, did you happen to dyno your car before the tune, just the stage 1 map that came with the accesport?

 

Yes, the car dyno'd at almost the same peak HP with the preloaded stage 1+ FMIC map as my final tuned hp number. However, the custom tune greatly smoothed out the power curve and made the engine hold that peak for much longer.

The big improvement was the torque curve. With the preloaded tune, the car peaked at 230-240 ft./lbs. And was again, not holding that torque. After the custom tune, the car's torque curve skyrocketed to 266 and maintained that mostly through the rev range. Much more usable power.

 

Not to mention, the boost curve and air fuel are much smoother than the preloaded AP map.
