Where's my re-map!!

[m0rk]

Your maf's dead... I'll put money on it.

You're hitting peak torque ~ 240lbft, then flatlines.

So either a dead maf, or an airbox full of dirt

 

[The MoffMeister]

airbox is needing to be sorted as it has a temp inlet to it which is not completely air tight, and maf i did think about so ill look at that, cheers mork so if i get them things sorted and then another remap it'll be ok??

 

[RobM]

If you get those things sorted you might not need another remap! If you MAF has died / is dying then the boost will drop by a fair amount, which will give you much less power.

When my MAF died I only got 6PSI and 160bhp from a LCR!

 

[The MoffMeister]

o blimey i see i thought that they may of flashed the ecu as im sure i would of been expecting about 200+ but if maf could affect it that much would the map still be on there??

 

[RobM]

Only one way to find out! You might find it's not the MAF, you might find it is and the remap is still there, but unfortunately the only way to test for sure is to change the MAF. As said though, a dead MAF can make the boost drop quite a bit, which you in turn mean you have a massive power loss. Also the MAF dying could cause slightly erratic readings, which might explain the big spike in your graph!

 

[ArosaRacer]

looks spiked as well not good, stretch heres my curve if you which to use it

oh and tech bods is this ok?

 

[The MoffMeister]

ok will buy maf and sort out air intake then maybe get another RR and go from there cheers all!!

 

[m0rk]

much easier to log on vag-com to prove it, then again if replaced

 

[CupraUK]

Given that on the same day I achieved:

210.8bhp @ 6105 From a peak torque of 222.4 ft lb

I would say that its not holding boost at higher revs. I'm no expert though.

can't really see the numbers to see how early it flatlines....

 

[tris]

Shame you didnt no that sunday i am sure someone would have let you borrow there maf

 

[CupraUK]

well heres the map guys so you techie heads what you reckon something simple or not will getting another re-map sort this out???

M0rk can advise much better than I can, but surely the fact that you are hitting such high torgue peaks does it not mean that your remap is there?

Could it not be something simple like your dump valve letting go?

The remap is there, as you say it's making the boost.

as it flattens out to a plateau it's either the MAF, or a physical obstruction (or the remap is utter ****)

 

[The MoffMeister]

utter **** i like that one lol

Well ill get maf done anyway as it was a second hand one that seat put on, also my engine management light has come on but engine runs smooth as so will see if thats something to do with it!!

cheers

 

[The MoffMeister]

Right have got new maf on way so thanx for that guys, hope this is the prob the one i had on there was 06a 133 356H so god knows what thats from

so hopefully get this in and see how it feels, thanx for all the help guys!!

 

[J@mes]

just as well u put your car on the dyno rob as it has confirmed you have a problem! good luck with the new maf too

if you need vag com u know where i am!

 

[The MoffMeister]

yeah cheers james knew it wasnt right and when i saw the read out i was like WTF, also maf says different code so i hope thats whats up, so bring on tues with new maf!!

BBBBBBBOOOOOOOOOOOSSSSSSSSSSSSTTTTTTTTTTTTTT!!!!

 

[J@mes]

well if the maf has the wrong code then surely theres your answer! fingers crossed!

 

[m0rk]

don't forget to do an ECU & Throttle body reset when you fit the new MAF

 

[The MoffMeister]

ah yeah almost forgot that cheers, thats turn off car isn't it disconnect batt for half an hour and tb alignment is open bonnet and drivers door with ignition on?
