Long live pre OBD vehicles!!!
The horse works…..Oh no, they're far too modern.
I say bring back carbs and points.
Yeah, but they've got no brakesThe horse works…..
With the right software, you can disable various things, including fault detection.This is the first I've heard of mapping out faults, heard of remapping for performance, mind you been out of it for a while now.
News to me as well.With the right software, you can disable various things, including fault detection.
It's a big can of worms for any future diagnostics.

A friend of ours burnt out a clutch up there, small camping trailer, stuck behind a group of lycra rolling road blocks.I won't drive anything that doesn't have a manual ignition advance/retard lever. The only proper test is 'Will it go up Porlock hill in top on full advance?'
This is potentially under test at the moment. A town not far from me, a large crash involving a young lad in a performance mapped car (his brother owned the remapping place), killed 4, 2 in hospital with life changing injuries. Raids and arrests made regards insurance fraud amongst other things. Will be interesting to see what comes of it.Would not supprise me if the insurers at claim time don't start pluging them in at assessment.
Check the CVN - and then void your insurance if mapped.
I am sure they would save themselves a fortune if they did....
They don’t like you having those, VED constantly creeping up.Yeah same here!

Thinking about this I remembered I did this once myself. I used to fit gas conversion kits for a short while when they were all the rage and did one on a jeep cherokee, for some reason while on gas it would put the engine management light on when next switched on, I fitted a relay to cut power to the ecu every time the ignition was switched off, cutting the power would clear any codes in the ecu thus stopping the light coming back on. I pity anyone who had to work on it afterwards.With the right software, you can disable various things, including fault detection.

The problem is, if they say 'it must have been done before I bought it, how was I to know?' the onus is on plod and/or the insurers to prove otherwise.It had to come - it just had to...
Maps with 10% to 30% for standard engines and up to 40/70%+ with hardware modified "Stage 3" tunes.
And just nobody tells there insurers...![]()
Bet it actually goes the other way, ie you have to prove it was not tuned before you bought the vehicle.The problem is, if they say 'it must have been done before I bought it, how was I to know?' the onus is on plod and/or the insurers to prove otherwise.
True but taking an insurance company to court may be quite expensive if they discover a car has been modified and it’s not been disclosed, wouldn’t like to be the Guinea pig.Innocent until proven guilty is still a legal principle in UK, whether you'd get a trial by jury.....
IIRC only HMRC require you to prove innocence, the CPS are required to prove your guilt.
I think it'd be them taking you to courtTrue but taking an insurance company to court may be quite expensive if they discover a car has been modified and it’s not been disclosed, wouldn’t like to be the Guinea pig.
Being devils advocate, I think it would be the other way, insurer makes a claim, insurance company finds out it’s modified and not disclosed.I think it'd be them taking you to court
Did you know it was modified? - no
Did you suspect it was modified? - no
It has the capability to go faster than intended, how did you not know? - I drive within the constraints of the speed limits and road conditions, I never noticed any extra performance as I have not driven any other comparable vehicles.
That's all it would take - 'blind ignorance'.
Not that I agree or condone remapping or insurance fraud, I've long been of the opinion that garages should be able to report vehicles taken away without safety-related repairs carried out - brakes, suspension & tyres for starters, emission control defeats and vanity plates could also be reported for non-compliance but I think most techs would be content with calling in safety related stuff.
