Jan,
I'm selling my MINI.

Will this work on my next car?

it's a BMW 135i.

Thanks

 

I think this has been discussed before, but I don't think anyone gave a definite answer. Does the canned tune take into account aftermarket mods such as intercooler etc.? Also has anyone done the remote dyno thing yet? And if you have what would be the protocol to accomplish that?

 

Yes you tell Jan what you have installed and he does his best to make the tune specific to your mods. And yes that has been answered many times.

I dont know about the dyno?

 

yes, it will need a different file now to read a BMW
I can send it to youwhen you are ready

 

This question may have been answered already. Does anyone or Jan know what kind gain (ballpark figure) can you expect to see from a factory JCW. Just curious before I drop a cool thousand.

 

This is definitely something that I wan to do. I may wait a little while since I only have 400 miles on my car but...it sounds like a MUST HAVE.

 

Sign me up! I can't find any posts indicating the GB is closed so I'm hoping I'm in. Just bought my S last week and already have a DP & CB on the way. Looking at ICs, susp & bushing kits right now. Also trying to decide how to put one of the 2 spare GT28RS turbos left over from a Porsche project to good use on this fun little beast of a car. I'm glad I found this site!

 

sorry miss post.

 

I'd check out some of the post's orangecrush has made about his car, I know he's posted up a bit of info about his tuning experience and he has a factory JCW

 

Second that, check Orange Crush's sig, or drop him a PM, I'm sure he'd be happy to tell you all about the gains. Simply put, you could go out and buy every after market part and still not see the gains you'd get from a RMW tune by itself.

 

This was a note Jan sent to me after asking the same question about what to expect from a RMW tune on my JCW:

What you will notice immediately is the speed at which the turbo spools, the power delivery etc. Most JCWs will make in the 10hp + range. Traction control improved, rev limit increase, quicker back on boost after a shift.

Jan can chime in here if he wants to add any more info.

 

I won't discuss specific tunes but let me say this. The numbers in my signature were a few tunes ago. Numbers produced are an "indication" of ballpark'ish range of what you will end up, not what any specific tune can do.

The real test is the performance of the car. I'm in GA right now at Roebling Road. I'm here to tell you that with my tune, I PULL past a LOT of cars that shouldn't be getting passed by a mini, JCW or not.

The numbers in my signature are REALLY low, I haven't been to a dyno since the new tune but I know how MUCH HARDER the car pulls that with the tune that was installed last year. I assure you Jan knows what he's doing.

Like I said, I haven't been to a dyno as of late, (just waiting for Jan to get close to me...within 500-600 miles) so I can get it dialed in but I can tell you the usable amount of power above the line is RIDICULOUS.

On a sad note, I melted yet another valve cover. Even though I double nutted the studs from my ED downpipe and welded a brace on the bottom, it continues to come loose allowing the heat to blow out and melt my valve cover.

This time, it just started when I caught it. I spent almost 3 hours in a parts store parking lot replacing studs with "exhaust" nuts. (apparently exhaust nuts are different....we'll see, I've double nutted them. At least the nuts are made of a different material and the threads are "crimped")

Today, I'll go beat the ***** off the car, there's going to be some ego bruising going on.

Despite this issues Mark had yesterday, I can back up the fact that the car is a beast. We are not in the same run groups, but I have been able to watch and listen to Marks car. Hopefully with the new bolts and nuts, the valve cover issue will go away..............He's got a great attitude about it and he'll be back out ******* it today......

 

Just got home from MOTD and I can answer the question about the RMW custom (i.e. dyno) tune and gas mileage.

It's a little over 550 miles each way for me. Last Wednesday, most of the drive was in the 40's and 50's and we averaged right at 70mph and my gas mileage was just under 35mpg. Cruise control on most of the time and no A/C because it was rather chilly outside.

Today, it was in the mid 80's and I ran the A/C most of the trip. I'm still not believing the numbers myself but this isn't the mileage the car's computer gave, this is the mileage divided by gallons (to the 1/10th of a gallon and mile) and I ran 37.8mpg at an average speed of 71.7 mph.

While at MOTD, it was amazing how the car ran! Most everyone with me was running in 2nd gear way up in the RPM range to have the power to pull through and out of those deep switchbacks. With a few exceptions, I found myself running in 3rd and I was pulling away from almost everyone coming out of the turns. Down the straightaways of the Hell Bender, it wasn't even a close call!

I'm looking forward to seeing what the generic tune will do, I'll load it up later this week and see how it does.

 

Got the tool and the tune. Haven't had the chance to drive it yet. According to everyone's result, I'm sure I'll be happy

Thank you Jan

I have not dynoed it, but the turbo definitely spools up faster and pulls harder, especially from 4000 up. No roughness or flat spots. The real test will come 5/26 at Laguna Seca, but I'm quite happy!

 

How do you like the flutter when the turbo blows off? I am still getting used to it.

 

Wife got the tool in today, Jan. Thanks

 

The turbo bov flutters let's everybody know you got a visious little animal under the bonnet.

 

Great feel

 

For people with the tune, do you have the pop and burble from the exhaust that was promised?

 

I have a 09 factory JCW and Jan took the pop/burble away. I want it back.

 

I only have the pop and burble when the car is still cold.

 

If you want the gag & puke, just ask Jan for it. It don't add power, just noise. I opted out.

 

Mine still farts just like before.
