Any way to tell if a car has been remapped?

    So I've recently picked up another 182, the previous owner seems to think it's had a different inlet manifold fitted in the past and a remap to no doubt go along with that. Is there a way to find out for sure if this is the case? It doesn't have the 5k kick so I'm guessing there is something there that isn't standard. I don't know if it is linked but the revs seem to hang around 1200rpm for a lot longer than you would think normal when you either put the clutch in at higher revs or coast down, it means that stop start and slow moving traffic is a pain in the arse as the car always seems to fight this and so has a tendency to kangaroo slightly rather than just pull from idle. Is this a sign of another problem, vacuum leak perhaps or merely a characteristic of whatever map has possibly been installed? Also the throttle pedal seems very sensitive for the first part of its travel, much more so than I remember it being in my Trophy which was still on the oem map, is this something which is normally altered with remaps? Any help much appreciated.

    My guess is it has matched inlets and a enlarged throttle body , the throttle body will be causing you all those problems take it off and put a standard one on

    Get it warm, if it redlines at more than 7250rpm then it's been mapped is the rough guide

    Pretty sure the red line on the rev gauge remains in the same place?

    However when it hits the rev limiter changes.

    lol I've never heard anyone refer to the redline as the rev limiter before, most cars I've had will rev past the beginning of the red line on the rev gauge?

    Pass on the redline, will try and get an idea when on my commute tomorrow and see where we are. Is it easy to revert back to a standard map? Otherwise I am tempted by an RSTuner setup but if the throttle body is different (how would I tell, again can take a pic tomorrow) then I guess it may still carry over some of the same characteristics would that be correct? Cheers chaps

    Measure the internal diameter of the throttle body by taking the inlet pipe off 64mm enlarged and 60mm standard plus you can usually tell if the body has been machined anyway , everything your describing is what these enlarged throttle body's do to these clios , it won't be your map if it has one

    Nice one thanks, will have a nose and see what it is. Would another throttle body just be plug and play I assume it is?

    it hasn't been mapped, they never have but it's always 'previous owner had it mapped' or 'really fast so has been mapped' etc...:wink:

    The "5k kick" is a myth anyway.
    Can't think why a remap would sit the idle that high either, unless it's had a a lightened flywheel and/or more aggressive cams.

    If it's a specialist eBay map it will be running at least 240 on the dyno.

    There is a kick, but its a fueling kick not a on VVT kick, thats the myth.

    My first assumption with those symptoms would be a bad job on the timing after cambelt swap.

    Ok so just to update this a little, rev limit seems to be at an indicated 7500 on the tacho and below is my throttle body so I would guess the next step is to source a standard one and then see how it behaves with that fitted.

    Haha I was actually right for once
    Ye put a standard throttle body on that should stop your issues
