Drivetrain The Always Up-to-Date Thread on Tuning 2011+ (N18) MINIs

Thanks for the help, Scott. Got the ECU out no problem. Those white clips were a little scary; I had to use a screwdriver to push the tab down to slide the white clips forward and down. I snapped some photos of the labels on the ECU and sent them off to Jan. I'll let everyone know what I hear.

i talked on the phone today with the engineer that does the ECU tuning of minis at renntech
lots of good info
both early and late ECUs can be tuned by renntech with the same results
the ECU must be sent to renntech in florida
the tune is activated by the sport button, with the sport button OFF, there is about a +10HP and +10 torques increase over stock, with the sport button ON, the full tune increase is available
the published increase are for an otherwise stock engine, more HP and Torque can be had depending on your mods
when sending the ECU, include a complete list of mods, including the brand and model, ie don't say "i have a CAI", say "i have a VIP CAI", they are familiar with all the mods available
renntech recommends the audi S3 recirculation valve or alternately, the forge recirculation valve, the audi valve is a direct replacement electrically operated valve, and is the same as found on the vw golf gti-r, they say it is much more robust and cost about $60
renntech says there is zero power gain on the N18 by removing the hot side muffler/resonator BUT it sounds better with it gone
an aftermarket intercooler is necessary to get max power, "the bigger the better" ... i said i intended to get the tyrolsport intercooler and he said it is a great choice
you can send your ECU yourself, you do not need to go through a dealer, however, dealers are free to set their own price and it may be cheaper, if you go direct it is $945
they will return ship the same day they receive the ECU

he did say the intercooler was the most important upgrade, and the bigger the better

Any idea how this kind of "tailored" tune compares to a dyno tune? Seems like this might fall somewhere between a generic canned tune and a dyno tune in terms of its individuality.
#334
#335
Funny that is the exact question I was thinking of.
IF you have added mods, the best tune is a dyno. Otherwise it is a guess. Probably a good guess, but a guess non the less.
Also you can actually decrease HP and torque by adding mods, and not doing a dyno.

I just got off the phone with Jags from ECU Tuning Group and the major talking points of our conversation are as follows:
* They can tune 2011, all 2012s, and 2013s
* They said we shouldn't see any CELs if we use true 200 cell racing cats, he specifically mentioned Miltek
* If you want the O2 sensor disabled to not throw a CEL with a dp they can, and WILL do it, but the dealer will be able to see that its been disabled
* THEY HAVE TO OPEN THE ECU to be able to tune, however he stated that once its tuned and put back together you can't tell its been opened and as long as we don't disable the O2 sensors the dealer will not be able to tell that the ECU has been modified
* They said the list of mods they recommend for most drivers are a FMIC(they recommend Forge), a panel filter (they say cone filters don't do anything and create a hotter charge), and a tune. With those three mods they said they saw an increase of 40hp and 60lbs/ft
*On a stock MCS they said they saw an increase of 31hp and 25lbs/ft
Both of the hp and tq numbers provided were gotten using 91 octane, if higher octane is available in your area they said you can expect to receive higher numbers.

Found some numbers for the RennTech tune on the TyrolSport website:
http://www.tyrolsport.com/engine/tra...w-n14-and-n18/
Those look like some pretty good numbers on the MCS N18 tune.
Stock Performance for Cooper S (w/ N14B16 Turbo): 173 HP/180 TQ
Modified Performance for Cooper S N14: 213 HP/220 TQ
Stock Performance for Cooper S N18: 181 HP / 192 TQ
Modified Performance for Cooper S N18: 221 HP, 232 TQ
Stock Performance For Cooper S JCW (w/ N14B16 Turbo) : 208 HP/ 193 TQ
Modified Performance: 248 HP/ 233 TQ
Modified Performance for Cooper S N14: 213 HP/220 TQ
Stock Performance for Cooper S N18: 181 HP / 192 TQ

per my conversation with an engineer at Renntech, those numbers are for an otherwise stock car, more is available with mods ... CAI, exhaust, FMIC, hotside/coldside upgrade etc
he also said if the CAI is a DoS style that is good, otherwise better off with a dropin panel highflow filter

I believe their website lists those numbers at the crank, if that is the case It would take A LOT to see 230 at the wheels.

I wonder if the valve RennTech recommends is the same one that was discussed on this thread:
https://www.northamericanmotoring.co...bov-valve.html
If so, it appears that it does not perform optimally on our turbos?
The Alta DV appears to be getting good reviews at the moment, though I'm not sure it is for sale.

ETG has told me they will for me, this may be because I live outside California or it may be something they offer to everyone, not sure, but they have the capability to do it and are willing to in at least some cases.

Been talking to Jerry over at NM for a while now beating around the idea of a tune for my 2012 MCS.
Been working a ton of overtime, decided to pull the trigger. His ECU guy is on vacation this week, so it's being shipped out for tune next week.
I've got only the NM Intake on my car now. My plan is to test out the adaptability of the tune to future modifications.
I'll add exhaust and FMIC to the car and see how the ECU adapts, then possibly get it re-tuned and see if I notice a huge difference.
Will report back as soon as I can get a review put together!

Jerry's a great guy there to deal with @ NM.
The tune will not 'adapt' to the FMIC - the FMIC simply allows for more timing to be added.
If you have an intake only right now, they will start you with the Stage 1 tune. Once you add the FMIC, you will need to step up to the Stage 2 tune to see the difference (and it's large).
I'm waiting for Aaron to get back on Monday to send my ECU out to get tweaked again, so I'm very familiar with their tuning. Just FYI.
