A Stage 1 remap takes the BMW M140i and M240i from 340bhp and 500Nm to around 420bhp and 640Nm on standard hardware. The B58 3.0 straight six responds this well because BMW left a wide margin in the standard calibration, and the extra 140Nm arrives much earlier in the rev range than the standard peak. The later 360bhp M240i finishes in the same place. Most owners have the ZF eight speed tuned at the same time, because it was never calibrated to pass 640Nm.

FAQ's
Coming soon…
Motorsport-exclusive components are explicitly designed for track use. While they can be installed on any vehicle, it’s important to note that using such parts renders the vehicle unsuitable for road use and may result in MOT failure.
No! Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.
Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.
In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.
No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.
Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.
No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.
Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.
We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!
We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.
Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.
Questions we get asked
How much power does a Stage 1 M140i make?
Around 420bhp and 640Nm from a standard 340bhp and 500Nm. No hardware changes are needed to reach that figure on a healthy car.
Is the M240i the same?
Yes. Both use the B58 and both finish around 420bhp and 640Nm, including the later 360bhp cars, which simply start closer to the target.
Does the gearbox need doing as well?
We recommend it. The ZF eight speed has its own torque limiter and will soften shifts to protect itself once the engine passes what it expects. Manual cars need a clutch that can hold the torque instead.
Will BMW be able to tell?
Assume yes. BMW logs programming activity against the vehicle and a dealer can see the ECU has been written to. We would rather say that up front than let you find out later.
