Engine Remapping

[fRostiE]

So i see a lot of posting about carbon cleaning or re-mapping on social media at the moment... i understand the concept but are there lots of people on here who've gone ahead and done it?

I bought my current car Leon FR 184 with a view to investigating the option of having it remapped with a warranty... thinking along the lines of someone like Revo etc.

I'm sure there's loads of important detail to know, like safe tolerances and if the remap has been tested on equivalent cars / engines to verify its not putting the car under too much strain.

What kind of things should i be on the lookout for if its something i'd like to pursue? Everywhere seems quick to provide potential gains and benefits but what are the risks, if any?

Obviously as its performance enhancing there's a need to notify the insurance company.

[edit] Forgot to ask, how does it affect manufacturer warranty, MOT and servicing?

Thanks,

Sounds like its certainly a cheap way of unlocking some extra performance... but not without caveats such as this TD1 ECU modifier flag.

I was wondering about one of those plug in 'DTUK' boxes which could then be removed. Their website says in fitting takes only 10 minutes, but i hadn't realised those boxes achieved the same results in a less 'safe' way. if for example the DTUK box simply overrides the inputs and safety features of the engine, isn't that the same as replacing the ECU software and raising those limits direct on the ECU? Just without the ability to disconnect and be back to stock figures?

The flip side of having a map applied over/onto the cars ECU is that its then not removable, and again even if it was this 'TD1' identifier still gives you up. Much less of an issue outside of engine warranty period though. Unless im misunderstanding some of the larger/more established companies warranty against engine damage. Though i'd not like be in that position as i'm sure the remap supplier will do everything they can to avoid blame/cost.

Servicing more regularly makes sense, as does no effect on the MOT.

I guess each insurance company looks upon ECU modifications differently so no point asking what to expect from that point of view.

Had a quick livechat discussion with someone at DTUK and when asked about the 'TD1 flag' they said:
"The TD1 flag is in reference to a ECU remap, as we don't touch the ECU and tune the vehicle downstream at the sensors no trace is left on the vehicle once removed."

Still tempted but not fully convinced
