Drivetrain ***OFFICIAL SIGN-UP THREAD for FLASH TOOL***
#1603
He knows exactly where the P&B mapping is, and knows exactly how to get it to do it....so no worries. Like you said, he wants to get EVERYTHING else figured out before he throws on something as trivial as the P&B. Also, not sure if you saw my other post about my latest tune, but it fixes the non-linear nature of the throttle.
We spent all day just tuning for driveability, and in the end I'm darn certain we're making a lot more power as well. The throttle is very linear, the car is a lot easier to drive smoother, and the boost comes on very hard, yet in a very progressive nature. Kinda what you mentioned, it would sometimes come on hard, sometimes it wouldnt...you really never knew what it was going to do. And a lot of the time it would instantly boost up to 18psi when you only were putting down maybe half throttle, which made driving it smoothly a challenge. All those problems have been fixed.

And to go with what engine said, this most recent tune has also helped signs of backfiring, which I used to get coming off the throttle/downshifting with a hotter engine. Signs AFR adjustments were improved

I would LOVE some of that.

Only getting a little confused here. Are you guys talking about the canned tune, the custom tune or both with these flat spot tweeks? I've got the custom tune and there was a flat spot at 3500rpm that Jan corrected on the dyno. It's been just fine for me ever since. The resident club hot shoe drove it recently and said it was the strongest MCS he'd ever driven. I can live with that, LOL!

Why do people have to start slinging crap and trying to start flame wars?
#1611
I think people were seeing it on canned & dyno. For me, it was dyno tune. Not everybody has the issue either, though. I had the slight idle issue on the dyno, and Jan took care of that then. I didn't see the hesitation of course till being on the road, so thats been dealt with remotely so far. Its gotten better, and I can tell things are smoothing out which is real nice. Looking for that extra reach to get it just about perfect.

if by patiently you mean fidgeting like a 5-yo that's gotten up too early on Christmas morning
There are tons and tons of ecu variations, it makes me wonder how Alta's able to test all the different combination's without doing the traveling dyno-road-show like Jan's been doing for the last couple years.

Thats easy enough to answer n1tr0. If they come across a different variation the AP is capable of collecting the info on the ECU and it can also data log a ton of parameters, these logs can be dumped to a PC and emailed to them. The tune can be tweaked from the information in the data log. Obviously not everyone one of their tunes will initially work 100% correctly due to all of the variations but they have the means to quickly update the tune and fix any issues that might arise.
I can't wait until Jan finishes with his updates and is able to start sending out updated map files for all of his customers with the MyGenius tool.

Thanks R56S! You also jogged my memory with your comment about not everyone having the same issue. I now remember Jan saying as he started my tune that he running into yet another different OEM map and code and this was last March! I think he said mine was the 7th or 8th one he'd run into. I don't know squat about programing, but could all these variations in OEM maps be the source of the confusion? Interesting to say the least!
I had a skipped heartbeat too at the dyno, as Jan initially plugged into my obd ii and said uh oh, this is ANOTHER new map--- thought I waited all that time and wasn't gonna be able to get the tune.haha he made it work though.

I'm wondering if the first and second gear limiters cause the bucking shifts from first to second? And to my homies that posted up the gti numbers all I can say is holy!!! Cats!!! No wonder that guy snubbed me when he passed. But then again I wasn't trying and I backed off after third gear and did the speed limit. It would be awesome to have those numbers in my jcw. How do we do it....

Just as a side note, it didn't just smooth it out, it accelerates much harder and the exhaust doesn't make the raspy noise (which I believe was the wastegate opening).
oh & that gti kit, aside from starting with some extra displacement, that kit includes a TON of hardware, most of which we don't have vendors even attempting to make for the Mini
Larger MAF housings, new ecm, bigger fuel pump, bigger injectors, bigger turbo, exhaust manifold, downpipe, ... and it's $5k in parts alone, not including install, hardly comparable to a flash only solution...

Yeah I checked out the apr site . They need to work on minis. Apr looks pretty high dollar too. That kits 5k and you need a cai , ic and exhaust. So with all that it's really high dollar. It would be awesome puttin that power down and still get 30 mpg at 75 mph. But i'm sure that isn't possible.

I believe this is the conclusion our local club came to, as we each tested out each other's rmw r56's. Two of us (me included) had our windows reprogrammed for the irratic behavior bouncing up and down (which mine still has and have accepted will never get fixed), and because of the window reprogramming/re-initialized, the ecu was updated. And it seemed the 1st gear lag was much more prominent on our two MINIS, whereas it was not noticiable on the other MINI's there. So, yes, it seems it could very well be the problem.

You wouldn't spend 5k for a working turbo kit on the MINI? Say 300+ to the wheels? I would. (If I had it...)
I actually have a couple of ideas for a kit, and one was close to being finalized but like most things in the aftermarket car world....plans fell through.

And lsd, R comp tires, wheels, Euro JCW Recaro Seats, harness, more HPDE days to learn to handle it.... $$$$ Just remember - in the end, you can't take it with you so have fun now
