Hi Folks,

You have a great forum here!

I will be picking the new car up Sept (Fabia vRS), and have been reading loads about chips black boxes Etc, Etc, how this is better than that. Now I'm more confused than ever!!

What I am looking for ideally would be a ECU upgrade that is switchable, by me, not the installer, back to MY, Stock program not one made up of a selection of 100 cars.

Was on the point of ordering and getting a date with "Revo" until I read that they go back to a "Stock" program not original one.

Again "Jabba" appears to get a mention but as far as I can see they dont do to ODII upgrade, rather some good solid work on the car.

I'm not looking to get the last bhp out of the car, just to give it a well deserved boost.

Oh and can someone tell me where on the car the ODII will be? not the sort of question the average salesman going to tell you.

So is it Box or ECU for the least detectable upgrade to my dealers etc?

All answers and opions welcome.....Thanks

Tuning boxes simply plug into the existing wiring under the bonnet to fool the engine management into sending more fuel into the cylinders for more oooomph and can be removed quicky and easily leaving no evidence of their existence.

And AFAIK there is no way of telling one was installed via VAG-COM either.

However, I had one fitted to my car and it bought up a few warnings on the dash that lead to some interesting Q&A sessions with my local dealer!

As for ECU upgrades, someone else more in the know will have to help out........

OBD-II port is behind the drinks cooler to the right of the steering wheel (it's a purple 16-pin socket)

Least detectable is tuning box as it can be physically removed prior to going into the dealers, however, both a tuning box and ECU remap have the potential to log fault codes.

Bang for buck, I'd go for a tuning box every time and when you sell the car you can sell the box and make at least half of the original outlay back!

I've had cheap tuning box off ebay for about £30 . For the price of the tuning box you cannot fault it except for the ECU light thats comes on after a few thousand miles but this can be reset by using Vag-Com. The more advanced tuning boxes are better but cost. A remap gives the biggest (much bigger than a £30 tuning box)

For switchable remap seek DMS, AmD, Custom Code.

Any codes could be erased using VAG-COM freeware and a cheap cable prior to going to any dealers just in case - if that was a worry. The code in question would probably be fuel temp sender signal implausable and I expect most dealers would know what you've been up to if they saw it.

It sounds like you want a switchable map which I believe REVO or AMD can offer. I also read here somewhere that another company could offer similar, may have been custom code. I can see the issue you highlight though about wanting your own map to switch back to.

Yes, I have read somewhere of a company that will give you a re-map and supply your stock code back on disk, they say they will switch it back for free 3 times, but in all the info I have collected I can't find them again!

How hard is it to read off/copy your own code?

Would that be http://www.superchips.co.uk/ they used to offer a 'customer key' or something.

I have sent you a PM.
