Gen 1 SW20 Turbo AFM

Postby solitaire » Tue Jul 25, 2006 2:54 pm

Hi Guys,

The 2 is running a bit lean... ive done the fuel filter etc and very little change (12.3a/f).

Can anyone provide me with the resistance readings off an afm they know to be at stock config at fully closed and fully opened please? Or failing that does someone in the auckland area have one i could come and look at/borrow/buy sometime?

Yeah there is a bit of conversation around that topic :cry:

A fair number of people on here both say too lean and ok...

The boys at torque performance say its way too lean....

I have a friend with a Gen3 pushing 200kw's who says it should be around 11.5

Its pretty much 12.3 through the whole rev range... it does fluctuate a bit higher at points... 8O

Im ready to turn up the boost but i dont want to grenade it...

Anybody have and dyno reports to post? Ill try and post mine up tonight..

In answer to your question 1 run was at 8.5psi and it was sitting on about 12.5, a month later i made another run at 11psi and it was averaging 12.3. I aborted the 2nd run that day and the torque performance boys said my next stop should be the afm as someone may of monkied around with it...

S4/5 RX7's also share the same AFM - worth looking at if you need to find one to compare. They do also have "tamperable" parts inside them, so its possible it has been fiddled with.

Anyone Got one i can rent/borrow/buy/steal? Even just the voltage/resistance readings off their current one would be awesome - im hoping to do the torque performance run this weekend but its a no go if i cant sort out my afm...

Cheers
