Ordered Sunday

Arrives Wenesday

Photos of install and review to follow

 

I look forward to it!

Just asking; any chance of a before and after dyno session?

 

Wish I could but Fat Larry is on Vacation,will do a Jcw tune vs Jcw tune + Racechip test on the dynojet.

 

just be sure you have a money back warranty...wish you good luck.

 

Zippy be positive.

 

Easy 5 minute install.

1. Remove 2 10mm fasteners on air intake.
2. run harness to connections@map,maf and fuel system.
3. remove test plug from harness and plug in racechip.
4. velcro or use included ziptie to attach to battery box area.
5. reattach air intake.
6. Start car and check for any warning lights.If you have warning lights check connections,if all connections are good check box to see if set to factory preset.

Impressions

Tested in 4th gear ,racechip builds boost lower in the range 1500/2000 rpm and holds it to 6500rpm. I can see where 1st and 2nd gear will have traction issues.

Very smooth throttle response and with the added tq you can drive it like a diesel shifting at 2000/2500 rpm

Performance wise I would have to say it pulls stronger then my 2009 fjcw did when equipped with just rmw high boost tune #2,akrapovic dp, forge inter cooler.

Cant wait to pair the racechip with the jcw pro tuning kit!!!!!!!!

 

So it feels decidedly quicker, and not a "I just paid money for this so I'm going to say it's faster anyways"?

One good acid test is to go back to stock and observe the difference.

 

Did a few 4th gear pulls lastnight connected and unconnected and there is a VERY
NOTICEABLE GAIN

feels like a few psi have been added and power feels very strong with nice gains throught the range.I noticed lastnight testdrive 72f high humidity verses the late afternoon 98f extreme humidity was cooler temps now make a bigger difference in how quick it pulls and very eager to bounce off rpm limiter in the lower gears.

All in all I would say very respectable gains under the curve with a noticable gain in peak outputs. maybe a 10 to 20% gain under the curve and 15% peak. Should be able to do dyno pulls in the next month.

setting was switch s1 7 s2 default

 

Ok, great to hear! Glad you did back-to-back drives Come back in a few days after living with it for a bit and give us an update if you would please.

A dyno would be fantastic.

 

The Jcw tune is tomorrow!

 

Are you getting the Bluetooth exhaust too? I've heard it and it sounds fantastic!

 

Jcw coilovers and full jcw pro tuning kit.Did order the Jcw pro side badges.

Have only found one car running the upgraded brake kit (r99) would love to get the dimensions of front caliper vs stock.Pretty sure I will need spacers. just how big do I need with the bbs 18x8 et 45? Trying to avoid nextday shipping fees.

 

Long time reader, and soon to be first time mini owner. Your posts are really helpful in planning for the arrival of my car - except maybe in keeping my budget under check :-). Did you talk to Racechip about how their machine might interact with the JCW tune? Does it assume a certain programming on the ECU and would the flash revision cause any conflicts? Thinking about getting the same and was curious as their site is not so specific.

 

Picking up car at mini of Orlando now. Suspension and wheels looks great! The tuning kit they had in stock only fit the f56. 😢

 

One of my new f55 and one of my old r56 fjcw

 

Spoke with Racechip Germany and asked about fjcw and jcw pro tuning kit compatibility and they responded that the racechip ultimate will work with FJcw ,Jcw pro and aftermarket ecu reflashes.

 

Thanks! The US guy said they'd have to adjust it. I presume I should buy the Ultimate version for the S. Looking forward to seeing all your mods in the other thread.

 

The adjustments are on the racechip ,default setting is s1.Once you have installed box you can raise it in one number increments to s7.Setting s1 is what racechip shows as gains in the stock vs racechip graph. Each step up is 1.5 % gain over default s1 setting.

 

Update

So far loving every minute of the racechip.Afer adjusting settings I have observed that the higher the setting of the chip the trasition to over boost is more noticable.As for mpg the downside is the higher the setting the more milage is affected.

very happy with the Racechip and hope to have similar results in the coming weeks when the f55 tuning kit is installed.

 

Roadtrip test

Did 140 miles today and each leg of the journey was blessed with great visibility and little traffic.

1000 Rpm in 4th to 5500 Rpm
1250 Rpm in 5th to 5000 Rpm
1500 Rpm in 6th t0 4000 Rpm

Car pulled very strong on each pull without the need to downshift.

The added power now gives more confidence when overtaking and merging.

In sport it feels like the transition to over boost is smoother while normal and green there is
pronounced spike in power while over boost is engaging.

 

350 miles of mixed driving on one tank. Pulled 4500 rpm in 6th

 

Glad you are liking it!!
The product racechip provided for older MINI cars was...er...
Let's just say glad to see you are happy with what you got!!

 

Maybe you are confusing Racechip with Unichip

 

Nope...piggyback is a whole different ball of wax...

 

1000 mile update

A few observations after a reset and testing box on all settings with pulls in 4th 5th and 6th.

1. the lower the setting the more linear the power band
2. the lower the setting the lower the shift point
3. setting s1 in normal feels like sport without box,s3 in green pulls stronger vs s1 in sport
4. current setting is s7 . Rolling start in 4th 40 mph to 80 mph against buddys gp2 with race chip ultimate ,downpipe ,nm intake and akrapovic exhaust ,f55 pulled 3 cars on gp2.
5. fuel mileage 340 miles per tank at 80 mph interstate combined with some heavy stop and go traffic plus 100f+ temps.2 people including luggage ac set on freeze.
6. after doing last reset i kept rpm below 4000 and speeds under 80 for 100 miles vs hammering it out of the box, now green and normal have much smoother transition to overboost and in sport the transition to overboost is very aggressive kinda like my old rmw tuned r56 fjcw but without the r56 feeling of no power under 2500 rpm.
