Title: Awesome ECU video - piggyback tuning box traps
Post by: remlapeel on 23 October 2015, 08:37: Just watched this video which is a great watch. What I did notice is 2/3 of the way through he mentions manufacturers are starting to place traps on the ECU sensors to trap piggyback tuning boxes. Anyone heard about these?

I learnt a lot there!

As for "implausable" data... don't we see those sorts of messages already?

Post by: vidman2 on 23 October 2015, 15:02: It has long been recommended that if you remove a tuning box before taking the car in car warranty work you should also run a VCDS scan and erase any error codes that have been recorded, to be sure there are no traces left (implausible data messages).

Post by: fredgroves on 23 October 2015, 15:48: I'm surprised that the car's system allows you to remove log entries... you'd think that the vendor would prevent log data tampering...

I bet most VW dealership techs don't know where to look! :grin: They couldn't find that EPC fault code that we hadn't erased. :rolleyes:

Would be interesting to hear from a VW Master Tech if this is really true or just a VW rumor to worry people, if this was the case surely Ross-Tech would issue a warning
