    Hi folks…

    I had a look and couldn’t find anything on the form about them, especially recently, so I thought I’d start a new thread.

    Does anyone use a tuning box of any kind?
    Im aware that a remap is generally superior however I’d like something I could remove before it goes for servicing that potentially won’t be picked up by the dealer.

    I ment to add - if you get a tuning box or remap how will this affect the DCT?
    I heard that if you remap anything with an Auto Duel clutch it can have a detrimental effect on the clutch due to the ratios being set for the way the car comes.

    I have a racechip ultimate installed.

    It's been pretty good, easy to fit and remove.

    I've been making enquiries this week about going for a stage2 remap, so will probably be removing shortly.

    Been a good experience, and racechip were good to deal with and promptly answered some technical questions I had early on in ownership.

    Thanks for the reply Scottch

    I just checked out the install for it on YouTube - It was a Clubman JCW but still the F56 engine so I’m assuming it’ll be the same as mine. It looks well easy compared with ones I’ve done in the past.

    I’ve ran a JB4 on a few of my F56’s with little issue. A remap will give you a better overall gain but the JB4 done ok at improving things. Matt also ran one on his F55 S with the DCT box so he’ll be able to answer how he found it with the box.

    I would add that dealers can still see if a tuning box has been fitted or not if they want to.

    Dead easy to fit, Alan - If I can do it anyone can .....

    There's only three plugs to connect to, the harness to hide (under the engine cover on mine) and I velcro'd the tuning box itself to the top of the battery box

    With Racechip there's a few settings you can play around with too, if you want a more aggressive power delivery or some fine tuning.

    You can see it in the pic attached.

    I’ve had my head chewed off for suggesting an upgrade already

    Might have to wait until she’s out and sneak it on

    We also had a JB4 unit which we tested on my F56 JCW (6-speed manual) before installing on my wife’s F54 JCW (8-speed auto).

    As Scott’s detailed above the tuning boxes are dead easy to fit.

    We enjoyed the tuning box and had it installed for the best part of 20k miles without issue. Not sure what the functionality is with the RaceChip (although I imagine they’re all the same) but with the JB4 you’re able to swap things on the fly (although once you’ve set it to your desired map I reckon you’ll just leave it there).

    Only downside i can think of on a traditional auto is that the gearbox essentially orders a burst of torque to sustain the cars momentum during changes. As the tuning box is piggybacking the factory ECU, it also interrupts and amplifies this input and so the gear changes can also become a bit pronounced.. It certainly didn’t ruin things but the gear changes were noticeably smoother on the standard map/ without the box. I’m not sure how this would be on a dual clutch transmission.

    I have a Bluespark Automotive box. Went for that as the JB4 was difficult to source at the time. Took about 30 minutes to install; most difficult part was working out how to disconnect the sensors. It is currently on setting 3 (of 5) and has noticeably increased power. They claim 282 but I see they now have a newer 3-channel version that claims more than 300hp.

    As William said, I ran a JB4 with the DCT and found it made a noticeable difference - especially at the top end. Gear changes were slightly more harsh, especially if you were foot to the floor but I ran with mine all the way to the French Alps and back with zero issue and it was still a very comfortable journey when just cruising along.

    I actually still have it sitting in the garage (with the Bluetooth module that lets you control it via phone app) if you decided on it and were interested.
