How to find out if my car is remapped?

[shauncr91]

I didn't know garages were able to sell modified cars even if they had been put back, a guy told me at the local Mazda garage that they have to auction off cars and aren't allowed to sell them on the forecourt.

Garages can sell pretty much whatever they want so long as it's safe for purpose, AFAIK any modifications simply have to be made known to the buyer?

On a note of your engine management light, surely it would only come on if your lambda was left out of the loop? My blueflame decat is made so that a lambda can be fitted thus no engine management lights on and no need for it to run extra rich at low rpm due to no lambda.

I don't know how it works on other cars but on the Fiesta ST there are two sensors, one in the manifold and one in the cat/decat and they measure the different readings between the first and second sensor to tell whether the cat is working or not, obviously on a decatted system such as mine the two readings are exactly the same so the ECU flags up that something's wrong.

Rolling road it to get a power figure?

There is an OcUK rolling road day in a few weeks.

It's too far away for me Hoping to attend an STOC RR day soon though in Hull at the Dreamscience HQ.

How would Mr Average car salesman even know that a car was previously modified?

Ah OK, I can see why there would be the problem now. My 306 gti6 only has the one lambda for fuel ratio at the lower rpms, nothing fancy to say whether the cat is doing its job or not. Have to hate technology sometimes!

Cars usually go through a stringent check before they are sold, these things would stand out before it was sold. Not so much for the remap I'm guessing.

Well mine came with OMP strut brace, K&N induction kit, eibach lowering springs and a couple more bits. When inspecting it I knew more about it than the salesman

Sounds like all the work you was going to do - has already been done

Yeah, a 328 with m50 mod. The delivery is such that you regularly find yourself hitting the standard rev limit.

Thats very different though, the m50 hardware changes the torque character completely. I think the original 2.8 makes max power at 5200!!
