Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: RMW Custom Tune Party in Austin, TX, Oct 15/16

OK, I'll pencil you in for 10am as a placeholder, plenty of time to change though.

 

No, that is not correct. A JCW 1st or 2nd gen car can also be tuned. From what I have read the 2nd gen JCW have some of the biggest gains from an RMW tune.

So, if you are interested, it is good for you that he does not charge by the hp/tq gain.

 

Welcome to MA, and sure not too late. What day/time works best for you and I will accommodate as best as possible?

 

Thanks Nathan, yes I will post a checklist and 1.5hrs is exactly what I am scheduling per vehicle. Since we can bill on 15 min increments, we only have to pay for the actual time on the dyno. Oh, and I will need a deposit to lock-in your slot, but not just yet.

And here is a little background info on the tuning process.
I will post some details later of some of what is tweaked inside the ECU. In a nutshell though, there are many parameters and maps/tables that can be changed. The tuner will get a baseline reading on your car including the dyno and the ECU. Then he makes his changes and uploads to your ECU and keeps iterating until your ECU/car is tuned for maximum performance.

A custom tune like this really optimizes what you already have and it can make a huge difference. Most people report better performance throughout the rpm range and many even get better fuel economy as well. While peak performance values are increased, and sometimes very significantly, to me the real value is in the everyday drivability and performance increase at lower rpms. Most of us typically do not hit the redline very often, if ever, and that is where the peak numbers are, at least for HP.

It is impossible to know exactly how much you will gain since every car is different, even with the same parts. BTW, this delta from car to car, is exactly why a custom tune is so valuable. These differences as well as difference in useage models, climates, available fuel, engine condition, etc are why our cars come from the factory essentially de-tuned, they must be safe for basically any operating conditions. Anyway, hopefully Jan will chime in with some data, but from what I have read a good guess would be a HP/TQ gain of ~12/12 from the factory tune. It could be a little less, and it could be much much more. It is probably better to take a look at some dyno plots to seem the real value, I think one of the guys from last year posted his plots. Again, I am not qualified to give you numbers, Jan is the guy that needs to say something here.

 

OK, I added the pre-tune checklist to the OP. I will add the schedule to the OP as we get closer.

Also, Wadodude and Greylens I have you penciled in.

At this point we are approaching critical mass, and about halfway full.

 

Ok sure, I will pencil you in for a Saturday slot.

There is nothing on the Jag site about this event, they are simply a great shop with a dyno in good condition with plenty of awesome Jags to view.

 

Ok, I just added the sign-up list to the OP since we just have 3 open slots left. We will have room for at least one alternate for each day in case we are running ahead of schedule.

PM me for deposits to lock-in your slot.

 

OK, penciled in for the 4pm Saturday slot.

OK, Saturday Standby/waiting list for you. The earlier you get to the shop the better your chances I will have of squeezing you in.
Edit: Ok, you are penciled in for 5:30pm on Saturday.
We can thank RonsMinnie for being flexible on his slot.

OK, penciled you in for 1pm Friday.
