Performance JB1 stage 1query for the non mechanically minded!

[ima]

Hi all

I know their are old threads on this but none clears enough to my non mechanical brain to work out. I’m really hankering for more performance and know a remap is a no no for warranty. Ive looked through the threads and other sites and seen reference to a JB1 tuning box. Other sites say tuning boxes are now detectable by VW brands including Seat and flash a TB1 code. This all puts me off as I worry about losing my 18 months of warranty if anything goes wrong. However, it seems the JB1 is the only tuning box not detectable. Anyone able to confirm this and if true, for a non mechanical person is it easy to fit/ remove for service. Waiting to the end of warranty I’d becoming unbearable!

Cheers for the help.

They say they are detectable, but it's only the same photo of a data sheet that floats about every now and agian, I've never know of anyone having one detected, in fact my s4 has been in for engine warrenty work and I removed my dtuk box before it went in and they never said anything, tdi tuning, dtuk, burger tuning etc they all act in the same way

From a recent post on uk-polos.net forum;

‘If you put one of these boxes on and have a drivetrain component failure, they are detectable by VW, if they take the time and effort to look hard enough. Piggybacking or intercepting MAF sensor/fuel rail/turbo boost sensor wiring and modifying signals is detectable (since the Golf/A3 facelift) by way of feedback to the sending source and the box causing implausible values for sensors’.

I suspect the same also applies to Seat, and if you had an drivetrain issue within the warranty period, Seat could detect that a tuning box had been fitted if they looked hard enough.

The experience of VW owners on some of the VW forums I’m on is that VW seem to be taking a firmer line in general with warranty claims - I dare say that the cost of dieselgate is a contributory factor in this revised approach. So VAG in general may be spending more time and effort interrogating a car’s ECU when there’s a drivetrain issue that’s the subject of a warranty claim to ensure the car’s standard before authorising the claim .

Thanks for the replies. Ah well it’s pays yer money takes yer choice then. All about risk taking by the look of it and as I’m risk averse it looks like I’m going to have to sweat it out at least until near the end of the warranty as it’s just my luck to chance it and get a hefty repair bill.

The issue of whether or not tuning boxes can be detected cropped up recently over on golfgtiforum.co.uk forum and one of the forum members linked into a discussion thread from a couple of years ago that might be of interest to forum members here. Link to thread below;
