MAF Specified staying at A constant level all the time?

Any Ideas what this means?

Its a 130bhp remapped fabia II

Wild guess... dodgy sensor?

Thanks for the quick reply.

Im trying to get to grips with whats going on here..

The maf actual graph seems to be working ok however the

maf specified just stays at 850.

Any other guides I can find to this problem show a good maf has the specified moving in tandem with the actual.

And a bad maf is the exact opposite of this. The actual keeps pretty constant.

Unless this is part of the remap?

Any input is greatly appreciated!
