Petrol and diesel Fxx owners - you can now all be tuned through the OBD port! Ask your remap questions here

Recommended Posts

Hi guys :)

 

As of today, all of the Fxx series cars can be tuned through the diagnostic port! This now covers diesel and petrol, and includes the twin ECU models (M5 for example). This means our price for both have come down massively subject to original files being available on our database. Prices and power increases for stage 1 tuning are below. We can also offer stage 2 and 3 tuning with the associated modifications. Prices are on request for stage 2 and 3 due to the sheer quantity of parts that vary between models. We can also offer additional options such as crackle on the over-run, launch control (on supported models) and hard cut limiter on diesels. These are charged as individual options - should you require an option on your quote, just let me know.

 

The OBD writing on these is subject to an original file being available on our database. If no file is available, we can still work on your car, but in some instances the ECU will have to be removed and a hole may have to be drilled for access inside the casing. We use a specialist drilling jig for this, so your ECU is in safe hands. However the price will change with this. ECUs that require drilling cost £372 inc. VAT (excluding the twin ECU models such as M5/M6) due to the much greater risk involved with working on them. We will always give you the option of backing out at this point before we begin drilling the ECU. Unfortunately there is no way of telling if there's a standard file available until we plug the car in. 

 

Our tuning software is also invisible to a BMW dealer. The car will pass the CVN check, and the flash counter will not increase. I must reiterate here that the software is invisible. If we have had to drill the access hole in your ECU(s) there is a chance that a dealer will remove the ECU to inspect it if they suspect the vehicle has been tuned. Whilst we can and do insert a blanking plug into the hole, it is still obvious the ECU has been drilled. This will void your warranty. If your car can be programmed through the diagnostic port, there is nothing to worry about.

 

Performance dial scales are adjusted free of charge to reflect your increase in power.

 

Feel free to ask all of your questions in this thread. The prices below include the forum discount for stage 1 tuning. RRP without the discount for this forum is also included.

 

If your file is not on the original file database (as I said previously there is no way of checking if your software version is available for OBD write without having the car here) the prices have been added in below.

I've just taken delivery of an F11 535d '64 plate which came with a year's BMW warranty.

 

For the purpose of clarity, are you saying that if I had one of your remaps, and needed subsequent warranty work from BMW, they couldn't wriggle out of a claim because the wouldn't detect the remap? Would you stick your neck on the line and offer to meet the cost if BMW did detect the remap and refuse to pay?

 

Also, interested on your thoughts on how the stock transmissions bear up under the extra fun put on them by your output claims!

 

Lastly, how do I get one!

Firstly don’t ask silly questions about the tuning company paying for warranty work due to you asking them to tune your car! ;) 

secondly they won’t be “claims” 

and thirdly pay them the stated monies and visit their workshop ;)  :P

Mr potatoes 

can the dealer not, detect a (un)detectable map by the amount of fuel used? 

As ive herd this is possible? So is it possible or was it possible or is it possible bar talk bull shit? :lol:

if BMW did detect the remap 

You're forgetting that remaps are and should be very detectable using your right foot.... 

 

 

And for the reasonable amount being charged for the service, i doubt liability insurance for a possible warranty refusal based on possible extra wear and tear from a remap is being considered. Who would agree to that? I think there are way too many factors to take account of.

That's a big torque increase on my stock engine.

 

And how would the gearbox fair with another third more twist going into it from what it is used to handling?

 

The 8HP45 takes it fine. From memory the diesels making 500Nm standard also use this box in auto form. There's also a lot of cars tuned by us (and others too, especially in America) running far more than 550Nm through it without any problems.

Does that also mean your maps can now be installed remotely?

 

We can install remotely but you would have to post your ECU to us. It can be done but we don't encourage it because we cannot test and datalog the car afterwards.

What we are saying is the remap will not be picked up by the software checks done by BMW. Should you be concerned we would even revert your car to standard for you for the time it was in the dealers. In regards to a warranty claim however, we will not meet the costs should BMW (or any other manufacturer of a car remapped under warranty) decide not to pay out. As pointed out by @SuperDave, a remap can be detected quite easily by just driving the car. 

 

In regards to transmissions, we've never had an issue with an 8HP box post remap. We've had one issue with a 6HP which when it went to a transmission specialist informed us it was the best part of 2 litres down on oil. A fluid change and filling to the correct level sorted fixed that issue. 

 

Either send me a message on here, email me at sales@harpermotorsport.co.uk or message me through the website live chat and lastly you can call me. All of my contact details are on our website - www.harpermotorsport.co.uk

 

In regards to claims, if you'd like to see a rolling road graph for a specific car, just let me know and I'll be able to get one for you.

 

And my name is Mark ;)

No that falls under the bar talk category! Either driving the car, CVN check, file checksum check, TD1 flag (affects VAG cars) and inspecting the ECU are ways dealers will check for a remap.

Where can you get this done in the south?

 

Unfortunately the only base we have at the moment is in the North close to Chester. We CAN do remaps by post, but we do prefer not to, and the onus is on you to make sure your car is mechanically sound before sending the ECU to us. We know our maps are perfectly safe, if the car is in good condition. Without having the car here, we can't inspect the car or run any datalogs to make sure we're happy with it.

And, apologies, I'm new here but who is Mashed Potatoes?!

 

I'm Mark and work for a company called Harper Motorsport. We've been building drift cars and have been doing remapping for years under the 'umbrella' of our garage Harper Autos. However as that got busier and busier, the decision was made to move everything performance related under a new company name, maintaining Harper Autos as a business for services and mechanical work, with Harper Motorsport running alongside taking care of the performance side. 

 

If you have any more questions feel free to ask away!

MP,

 

So you would need the ECU to unlock it to accept maps from OBD?

 

Also are you're maps set data sheets or would I have the option to tweak certain aspects to suit my own driving style.

 

I would like to have a map installed, unfortunately however I do not have the time at the moment to visit you up north.

 

Thanks

The ECUs no longer need opening up to unlock, they can be programmed directly through the OBD port. However we can still program on the bench - that's not a problem for us to do. We just wouldn't use this service for the petrol ECUs and the diesel ones that require drilling. Due to the increased risk working on these ECUs, after drilling and cleaning we reinstall the ECU and start the car up to make sure there's no issues. We've never had a problem with one, but I'd hate to put one in the post and then find out there's an issue when it's received back. Being a 535D, your car will be fitted with the EDC17 CP45 ECU that requires drilling.

 

We are open Saturdays if that helps! 

 

We generally have set stage 1, 2 and 3 however there is a little room to play sometimes. However you cannot get around the characteristics of the engine if you see what I mean without changing hardware. You won't be able to 'move' the torque curve from the engine for example.

I started reading this with excitement that my F10 530d is tunable via OBD -  but whats the caveat about original files being available on he database....... is it or isnt it tunable via the OBD..... F10 530d LCI. What does it depend on .....? Thanks . I'll check out the website.

The ECUs cannot be read through the OBD port, only written. The original file database contains standard files submitted from tuners like myself to the company that manufacture the tools for reading and writing to the ECU. So if we get a car in that when read, doesn't have an original file on the database, the ECU would be opened up and read that way. After your car is tuned and you're on your way, we will submit the read (which is done in what is referred to as boot mode with the ECU out of the car on the bench) to the tool manufacturer and it will then be available in the original file database so should another car with the same configuration, hardware number, software number and upgrade number be checked against the database, we or anyone else that uses the same tools as we do would be able to program through the OBD port straight away without having to remove the ECU.

 

There's well over 2000 original files for BMW on the file database, so it would be very rare for your car not to be covered. I did @SuperDave's 530D a few weeks ago and we had no trouble. His file was on the database. Unfortunately though there's no way of checking without plugging the car in first. 

 

I will update the first post in this thread with prices for ECUs that need to be removed too, so all bases are covered in this thread.

 

Feel free to ask any more questions!

F10 520D.

 

121,000 miles.  Oil and filters changed recently.

 

Talk to me.

 

Hello!

 

Being the Efficient Dynamics model I believe your car will be the 163BHP version - they pick up around 60BHP. If you send me a PM with your registration I'll be able to confirm it for you. 120,000 miles isn't an issue, it's a pretty underworked engine anyway. The only thing we'd look for would be any whining sounds or similar from the turbo, especially when cold. A 520D is pretty common, so I can't imagine your original file NOT being on the database, but if you want to check if your ECU is the one that would require drilling or not, pop the bonnet and remove the screws on the lid for the ECU box. there may be a few small connectors on top with the lid off, but the ECU is underneath. If you see 2 large plugs, your ECU wouldn't need to be drilled. If you see 5 smaller plugs that'll be the one that needs drilling. The screws in the ECU box lid are T25.

I was going for the Terry Tibbs 'PhoneJacker' approach.

Hi

I have a 2011 523i, and would be interested in getting a remap. 

 

I enquired with the likes of superchips and somewhere else a year or so ago, superchips didn't do anything, and the other place said they could build a bespoke remap but would need the car all day, but could only offer 30hp increase. 

 

So 60+ hp increase is a big jump for a non turbocharged car... 

Is that definitely right? 

What does it do to the fuel consumption? 

Obviously the 523's were a "detuned" non turbo version for better economy... But 60hp....
