hey guys, what are afm's?

markM3 · 7th January 2010, 08:39 AM

Air Flow Meters - situated just after your airfilter.

Cheers,

..and some GTR's run without MAF's, then they would be using MAP sensors instead and some sort of engine management system such as Power FC.

Ive got v.slight shuffle, but not alot. Apexi AX53B60's running 1.45 bar.

L jectro apexi power fc works with MAFs. D jectro runs with MAP sensors. All clever stuff!

WETUNERDREAM.. MAF= Mass Air Flow MAP = Manifold Absolute Pressure sensor. ( if nobody tells you, how will you know?)

i have -10s but on the larger rb26/30 so the shuffle does not affect performance.
at times i can hear the shuffle under load in a high gear but once boost starts ramping up it completely disappears

i have twin GTSS , modified "twin turbo" pipe and no AFMs and my car shuffle when on light throttle

Mark@Abbey M/S · 9th April 2010, 02:15 PM

i was thinking about getting the twin turbo pipe mod done but if u still get light shuffle - what is the point...

im just inthe process of buying an f-con v pro gold 3.2 and going maffless as going to be running 2860-10s im banking on the mapper then being able to set my car up with no shuffle

.

Marko R1 · 10th April 2010, 10:13 AM

What is maffless or is that a typo?

hi mate,just
means im doing away with my air flow metres and letting the new f-con pro v 3.2 gold ecu sort it all out.its just that im hoping by getting rid of the afm"s that should stop my car having turbo shuffle as i think "turbo shuffle" is somthing to do with air flow and having 2 afm"s is a contributing factor.

i can hear it and the car loose power until i give it more or less throttle...

when it appear the car seems to hesitate and the boost gauge is moving really fast up and down.... really annoying because it appears on light throttle for example when driving on motorway...

is there a risk for the engine or turbos when driving with shuffle?

Mark@Abbey M/S · 13th April 2010, 06:57 AM

Sounds like it has either a Crank angle sensor problem or a small air leak , it never did that when we tuned the car for Mike to original owner.

There again your going over to Motec so your tuner will be able to sort the problem wont he.

No real problem with the shuffles at part throttle thou.

Twin 2860 -10's, no AFM's, Motec M800 management, Tomei 280 degree 10.8 mm lift cams, ported head, stock TB's, on a 86.5 mm bore, stock stroke RB26 with all steel internals. No shuffle at all, makes usable boost by 4000, still making rising boost at 8500 RPM. Professionally mapped, which I think is a big part of the secret, plus the lack of AFM's, which are notoriously sensitive to cam timing and air reversion or pulsing.

i've fitted an OEM airbox with Blitz air filter and the car don't shuffle anymore... not only the noise has disappeared but boost oscillation has disappered too... car runs like a dream now...
