Flat spot around 3krpm

[Number86]

Hey Chaps.

The car seems to boost fine usually, and this is NOT an intermittent problem. From about 3 to 3.5krpm the car accelerates, but doesn't seem to boost as much or as with as much force before or after this range. It's not a massive drop, but it is noticable. As when you floor it, pick up from 2.5k is awesome, slows down at 3k, them picks back up around 3.5k.

Is this a MAF problem?

As another question (as I don't have another LCR to compare with) When you change up a gear (during acceleration) I change up, then fire back on the throttle. It takes a second or 2 and then you feel the acceleration come back on. I am assuming this is just turbo lag after changing gear, and not anything else. But I thought I may as well ask

Thanks!

It could be your maf! Do some logs! or could be your N75 valve could be playing up!

I have no way of doing any logs of antything, also very new to seats/LCR!

 

[Big_daddy]

what car is it?

 

[Number86]

03 Lcr!

EDIT: Remapped

Could be a MAF problem, could also be your N75. Could be a number of things though... so stick a post up in the VAG-COM 'Help Requests' forum section to see if somebody in your area has VAG-COM and can help.

Could the flat spot be related to your remap? Who remapped it?

 

[Number86]

performance torque did it. He said this isn't a characteristic of the map, and I'd be inclined to believe him for now. Which means it's showing up something elsewhere?

 

[Johnsey]

Was the flat spot there before it was remapped? Can the map be removed temporarily to eliminate it as being the cause?

 

[Number86]

Well, I'd only had the car a very short while before hand, but definitely didn't notice anything before the map.

Get yourself along to a local meet, maybe someone there will have a copy of VAGCOM to do some logging or even swap MAF's for testing purposes?
Do a search for "flat spot" or MAF and you'll see what I mean.
