Dustin,

Can we also assume a turbo back exhaust system?

 

A turbo-back exhaust would be nice. If Vishnu wants some help, I've already done mine with very good actual gains.

 

I'm in...but my R56s will not be here until July/August. Hopefully jus in time when the mod is fully debugged. Can't wait!!!!

 

good luck, hope ya get it sorted. Development is always hard, I know, had to report back issues when I drove as a durability driver for BMW here in LA and back in 2000 the prototype minis we had always broke down :p

 

Update: We made some good progress today with respect to timing and boost control. The development we poured into the 335i application is certainly helping us out with the Mini project. Will keep you guys posted as things progress further. Might have some dyno numbers for you within the next couple of weeks :]

holy crap dude that's great news! Keep us posted and good luck!

 

i think i wet myself.... yup

 

As soon as I saw the announcement that Vishnu was going to tune the R56 I knew one thing: I can never buy an R56!

I've seen the reports on the Vishnu-tuned Evos, and they seem to be amazing cars. I don't even want to know how good their MINIs are going to be.

I'm just gonna drive my R53 forever, and adopt a don't-ask-don't-tell policy when it comes to the magic these folks work on the R56. But the rest of y'all have fun!

 

Muahahahahahaha!

 

Great to hear from you. Post the updates as they occur!!!

Some reading while we wait-

You mail your ECU to Vishnu with $750 and you get 400 hp and 400 lb ft of torque in the mail two days later.

Product Overview:
Even in stock form, the 335i is a potent machine, but fortunately, BMW left quite a bit on the table to work with. Through precise and methodical calibration with the Vishnu PROcede computer, we are able to extract another 55-60whp and 70-80lbft of torque. These monstrous gains are achieved with only two more pounds of boost from the clever factory twin turbo set up.


That's scary.

 

Well, $750 for ECU alone is the stage subzero package that "only" produces 380hp (the $1,995 400hp stage 1 kit includes a turbo-back exhaust).

But 380hp from just an ECU is simply astonishing when considering just two years ago the much more invasive $2,995 Evo VIII kit required cams, exhaust and turbo housing to produce a similar 381hp (Car and Driver saw whp go from 202 to 284).

We can thank Mitsubishi and BMW for making the engines of the Evo IX and 335i relatively free of bottlenecks so Vishnu could squeeze out lots of extra power from only software. Hopefully the design of the PSA Prince engine will also lend itself to producing plenty from tuning alone and without having to change out much hardware.

 

Any news yet?

 

Pins and needles.. And I hate needles.

 

so hows the progress?

 

Progress is coming along nicely. We are learning quite a bit about how the factory computer controls different aspects of the motor. With more testing time, we will be able to confirm these assumptions, at which point we will let you guys in on the details.

 

I've read where a couple of guys don't like the "piggy-back" systems, why is this

 

I think in our situation the piggy back is a better way to go. This way it can be removed if we ever need to take it in to service. An ECU flash is detectable.

I am ready

 

Not to knock the vishnu guys at all, or anyone else running a piggyback, but a bosch me9 computer is extremely complex and really friggin expensive to produce and is pretty damn good imo. I don't want to trick my very expensive ecu into thinking its running fine and letting a $1000 black box blindly control tuning... Its why I like reflashes better, factory driveability, tuning, and reflashing. I'm sure the vishnu proceed is a great product, but its a reflash for me. Also the factory solenoid controlled DV/bov is awesome, it makes driveability significantly better than any other turbo car i've driven bar none.

My $.02,
Josh

PS- Ecu flashes are not necessarily detectable. APRs product for the VWs are invisible to dealers. Enjoy!

 

Wow a tuner with a great attitude. Very nice addition to the Mini community with a track record to back it up.

Glad to see some good modding news for the R56 owners.

 

Coming from the Subaru world and COBB Tuning, having the Accessport and the ability to flash your ECU to whichever map you wanted was awesome! Then, if service was needed, just flash back and bam, your back to stock.

 

Agreed a lot, the VAG cars are way beyond piggybag stages. I wish APR had any interest in the new R56. The good thing about the new Bosch system is the protection files that will protect your engine from overboost, timing retard, high EGTs unless the tuners crack those maps.

I would like to see big players investing some time and energy into this. BTW, I testdrove an R56 w/LSD, can you say torque steer? I dont wanna know what will happen with more power

 

You just need bigger forearms

 

The newer chiptuning for the GTI is nothing short of staggering, apr does an amazing job. When you drove the r56 did you have sport button on??? I find actually that non sport is less torque steery (yeah i know not really a word.) The car as long as you point it in the right direction goes fine for me =) My gt35r a4 will be the fast one lol.

Back to the topic at hand. Someone tune these cars!

 

The sport button does not alter boost levels AFAIK. It only changes steering & throttle responsiveness.

 

This mod requires modding yourselfSee this is what I don't understand about the gimmicky sport button--when would anyone want slow responding inputs?

And I'm the guy that complained the MCSa auto trans was too hyperactive by default and needed to act more conventionally until a sport mode was selected. That I can understand the need for (in the MCSa examples I have tried, it was simply impossible to drive as smoothly as a manual trans) because being kicked around all the time gets old fast during the commute. Mercedes automatics used to actually start in second gear for extra smoothness unless at WOT.

But dulled responses to throttle and steering inputs? Needs an auto-up module fix
