i have a f-con (not the full ecu though)

and it hated the map sensor being moved, it mucked up the fuelling all over the show. make sure its mounted securely to the bulkhead and level.

thats all i can think of. unless the sensor has had it completely!

probably a hks 3bar map sensor, so not cheap to replace! but id doubt its that, just refit securely and remap if necessary! just map it on the road get some1 with a wideband to do it for you. cheaper than a lengthly dyno run.

its likely in perfect working order, not a button wrong with it, but needs fitted securely and fitted level. hardly worth throwing other map sensors at the problem if its nothing major?!

i don't think they can, they don't have any software, it only went up for an engine management light on, needed a knock sensor replacing!! and crank seals needed doing!

I'd agree lad, the sensor can be rather sensitive to movement.

What was up with the knock sensor?

i'm not too sure, i got a diagnostic done but the printout is with the car. they changed it and its ok now, but they must have knocked something about!

Aye, possibly just upset something simple when replacing the knock sensor as it's buried down the back of the engine block.

Is a crank seal leaking as well? Which end?

Can't see them affecting the MAP sensor by doing the seals, it's too high up.

It just sounds like the sensor or wiring has been moved during the knock sensor replacement.

yeh i'd say your right! maybe a stupid question but that won't require it to be mapped again will it?
