If you don't live near a tuner, you will probably like the MTH tuning better than others. The idea is that you buy a special cable, plug a laptop into the OBD diagnostic port of the car with it, and copy the ECU programming to the PC.

You then send this file via email with a list of your mods, and MTH will return a modified version, which you then upload into the car ECU from the laptop. You can also re-load the original code if into the car if you've got a snotty dealer, which no other option I'm aware of can do.

This won't get you the last handful of HP that a true dyno-based custom tune could offer (only if the shop really knows its stuff), but it's maybe 90% of the benefit for half the cost.

They will also provide updated tuner files, as you add more parts, for a year. Look here: https://www.northamericanmotoring.co...play.php?f=134

thank you sir for all of the valuable information . i will take a look later today when i have more time. i just might have to go ahead and get this done once i get the pulley and (at least the exhaust) done.

 

Realistically, I'm guessing that the MTH ECU upgrade added 10 or so HP to my car (on top of pulley, JCW intake, and Borla Steet cat-back). I haven't dyno'ed the car, but I'm guessing 195HP in MINI-units.

There are other nice features available as part of the package as well - they can up the rev limit a few hundred RPM, reduce the intrusiveness of the ASC/DSC without turning it off entirely, and remove the drop-throttle overrun (let the engine RPM fall back more quickly when you get off the gas). All of these make the car more enjoyable to drive.

 

with mine being an automatic, would the programming have any affect on the tranny? i wouldn't think so, but again i really have no idea.

 

MTH: $775 for the canned package. They have an auto specific package as well.

sweet!!! i will definately check that out later on today! thanks for the help.

 

they allow you to add it to the cart and assess shipping. I'd like one.

 

Dose anyone know if the JCW injectors for 03 and 04 Copper S are the same as the stock 05 and 06 injectors?

Some dealers are advertising a JCW upgrade (Item #11 120 395 131) that consists of the following:
JCW air box (CAI)
JCW injectors
JCW ECU (I believe that this is software and although it is sold in this package, it can only be installed by stealer as a download. They will charge additional labor).
http://www.trademotion.com/partlocator/index.cfm?action=accessoryPart5&siteid=214201&cata logid=3751&categoryID=75816

The dealers that have it advertised on the web say that it is only for 2003- 2004 Cooper S. I thought the JCW C.A.I. and ECU software are the same for all years (2003 - 2006). Am I wrong to assume the stock injectors were upgraded in 05?
Before I drive 1 hour, I want to make sure I am not getting hosed or paying for stuff I don’t need.

 

i did email them and got a reply. they will let ppl purchase it, but you have to set up your own shipping carrier. so now i am REALLY considering it.

 

did they give you box sizes? I'm more than happy to send them prepaid labels

 

no they didnt but i am going to find out and then ill let you know

 

What it means is that if you bought an '05-'06 JCW car, the "upgrade" was already part of the package, so if you had an earlier, dealer-installed JCW package ('03-'04), it would not have had the upgraded injectors/airbox. The upgrade package is marketed to '03/'04 cars which likely have the original JCW kit. The upgrade package is/was already part of the '05/'06 JCW package. I don't believe the '05/'06 MCS has the JCW's 380 injectors.

 

thanks. they aren't so good with returning emails

 

70spop, i believe you are correct sir.

 

The '05-'06 Factory installed JCW MINI does come with the JCW's 380 injectors.

 

maxicooper, dont you ever get tired of being right all of the time?

 

as soon as i find out i will let you know.

 

Right. What I meant was that the non-JCW '05/'06 MCS does not come with the 380 injectors.

 

That would be correct...

 

This is good,since mine just arrived ......one week til tune with Jan!!

 

Isn't the Jan tune like $395.00 plus the dyno time?

 

I was hopin' 350$.

 

Prices ive seen and the price im paying is 500-550 but is well worth the money...

Jack

 

If you get the kind of gains that I've seen posted, it's very fair! When he comes with in a reasonable distance from me, I'm all over it!! Can anyone give an average gain for a car with the mods I have listed?

 

Last year, I had pretty much the same set up as yours. JCW intake, JCW exhaust, 15% pulley, JCW injectors, JCW plugs, and JCW flash. Dyno @ 173 whp & 155 ft/lb.
