Just had my Z4 20i Mapped to 280BHP by Celtic

[Msport]

Wow- what a difference

Bought this car about a month ago, knowing it has the exact same engine as the 28i but with de-tuned ECU.



Waited a month for this, and today was the day Celtic Tuning arrived at my workplace to unleash the power on my vehicle, and WOW.. what a difference!

I was instructed to take the vehicle on a test drive after completion of the re-map, and it instantly put a grin on my face, the car has been completely transformed into a different animal.

My other half noticed the improved performance instantly ( I didn't tell her about the re-map), I said it was down to the car being "serviced" today

Happy times the 4pot does offer a lot of potential for relatively little outlay.
Enjoy the torque

Chuffed it worked out so well for you, I followed the remap threads and was about to go down the same route when a 35iS turned up at my local dealership ! I’d love to have experienced the difference a remap would have made to my 2.0 Enjoy the “New Car” and drive safely

Nice one. You do know she will find out of course. :wink:

The car still scares me as it is thanks Stuart :crazydude:

 

[Msport]

Thanks- the difference is considerable, more so than I envisaged, but I imagine your upgrade to a 35iS is even more considerable so I'd say it must feel somewhere between the two!

And when you get bored, as Stuartt says, you can get it remapped to 392BHP

As it’s a mod to the original vehicle, what has it increased your insurance by?

 

[mackharry]

So from 184bhp to 280bhp? that's some improvement, just had a look at quantum and they say they can get to 260bhp, to celtics 280. Id be interested to know the insurance difference too

 

[Gabz]

Bless remaps! MHD took my 35i from 305bhp to around 370bhp - what an insane difference.

 

[Steelee]

Did they do did it via the port or remove the ECU?

 

[Broads]

Can't wait for my extended warranty to run out, may even be tempted to do it after my service. Its great to hear another that has done it, and has enjoyed the extra gains.

 

[bryand]

With respect to the insurance questions, I rung my insurer the other day and asked this exact question, was quoted an extra £47 which I think is perfectly reasonable.

that's a small price to pay for that extra bhp, enjoy

My wife still thinks my remote roof control is the result of 'some quick coding' by my indy, not a £100 gizmo I had to buy & fit

That is a great result though

 

[boatyhacker]

Thanks for the report. I’m waiting for my warranty to run out too and then plan on doing the same. Good to know that the performance feels like what is being advertised!

How much was it? Can it be done remotely?

 

[syyzed]

Serious gains, just requested a quote on my 28i

 

[Msport]

It cost £295. And yes, they came to my work for that and did the remap. To answer other people's questions, I'm not 100% sure but I think they did remove the ECU to do it- it took them about 2 hours. Difference was night and day after and no fault codes or problems since. I even get better MPG now (when not booting it) because of the increased torque. If your map ever gets wiped, for instance if you take it to BMW and they update the software on a routine service, they will come to you and put it back on for £75. Highly recommend it, loving the extra power and torque.. feels like the car should be from stock. Insurance cost £50 extra.

[superdot]

Probably not worthwhile doing on a 28i is it?
