Positive Deviation: PROBLEM FIXED!

Hey, Just thought i would post up to say I have fixed my postive deviation problem finally thanks to the help of Simon_L on here who kindly did some logging on vag-com for me last night. As it turns out my brand new MAF from Seat was faulty and overreading, causing limp mode if you rev'd in any gear past say 5500rpm. It was so frustrating, but there we are easy fix afterall.

Did manage to leave a celica vvti in my smoke in the process aswell who was being an knob sitting up my arse, once i swapped back to my old MAF.

Well chuffed now!

Thats the same problem i had mate.

 

[Spud_G40]

I know, just did'nt think to try my old MAF again... The one on it was brand spanking new.

 

[Sharky_82]

Frustrating isnt - disconnecting the maf comes to th same conclusion - its one of the first test i should have done but end up doing it at the end - lol

o well....happy days again!!

 

[ibizacupra]

what figures were you getting with new maf vs old one?

 

[Spud_G40]

I will post up the figures once Simon has e-mailed them to me.

The MAF figures from both were near identical.

I had the same issue with a brand new MAF. Swaped it back for the old one and the car ran fine. Suggested this last night and it worked.

The Celica was amusing, did a u turn on a roundabout, Spud stuck it in 4th and i was logging in the passenger seat. Engine was spooling up and the Celica was full on going for it. Once the turbo spooled up we were away, very very amusing

MAF made around 180g/s, and the boost peaked at ~17psi. From the MAF readings i reckon its around 240bhp, and 230lbft. Inlet temps were mid 20's too. FMIC working very well!

what problem did you have if i leave the traffic lights and floor it in all five gears it peaks at 1bar then holds at 0.5 bar if im just crusing at 30 in second say then floor it it peaks at 1.5 bar then holds at 1bar very strange mine problem is

Yours does'nt sound like a problem, sounds fairly normal. Mine went well, but got to around 5500rpm and it more or less spluttered, and put me into Limp mode e.g. no boost and very very flat power/response/anything.

mine does not feel like 228bhp like jabba say my problem is so hard to describe with out you driving the car you would not understand

 

[Spud_G40]

Hhhmmm, Have you checked all your ic hoses for a boost leak?

 

[stevegti6]

yes i have there is no boost leak any where

The celica thing was very funny, whats even funnier was we were'nt racing, we were 'logging'.

Hello mate,

I think thats my old car you have there. I would be surprised if it is 228bhp unless someone has stuck a K03's on it. When it was mine it was about 200bhp plus or minus a couple.

Good car that was.

Mark.
