Can I fix this thing by using the safc? It's really annoying when the idle is 2000rpm. It plays with me. - Returnless fuel line - maf.
I'm not going to use an fpr only the safc. Any help?

did you check the vacuum and pcv lines for leakage?

everything is cool . I guess this is a problem from the bigger injectors. They are from beta 2.0, I have alpha 1.5

Anyone?

Yeah that problem is really annoying.... I had it for the longest. I never tried using the emanage to fix the problem as i removed the idle speed actuator long before i installed emanage. I set the idle with the screw, u know, like u do on a real car ;-) Only problem with that is if you have a/c (like me) then the idle gets low when u turn it on, so u have to turn the idle up (mine is set at like 1050, 1100).

Yeah.. like a real car with carb and no crap ecus.. I know. Well better 1050 than 2000+. Thanks for the advice man. I should try this till I get my safc

just make sure you leave the elctrical connector of the isa plugged in to prevent a code and ur good =-)

I did it but the idle won't go lower. In fact, when I remove the plug the idle is getting higher and when I adjust the screw it goes only higher. Not lower. So I insist... will the safc2 fix the problem?

Hey guys,

I have gone the same route as omg, and removed the idle speed actuator as I have a 2000rpm idle with Large injectors in the 1.5. I simply left the electrical connector connected on the ISA, so I get no code, and in the pipe between the ISA and manifold inserted a mag wheel nut and I did the same with the pipe between the ISA and the intake pipe between the MAF and the TB. The mag wheel nuts are of a size that they can't possibly get sucked into the motor, but for good measure, I have them clamped and Sikaflex'd into place also. While she's a little more difficult to start in the morning, any person willing to call themselves a 'driver' should be able to overcome any shortcomings in the ISA's removal.

Happy motoring all and stay safe.

Remove ISA is possible in a MAF car really? I remember some years ago, tried to close ISA hose with a little filter, and car stalls

Japakos......is your butterfly-plate fully-closed at idle?..........whilst your bigger injectors could be responsible for the fast idle, it`s also possible that an incorrectly adjusted throttle cable (or throttle body internal screw) could cause your problem!.

If you removed the isa hoses and plugged them off you HAVE TO leave the electrical connector plugged in. If you unplugged it then plug it back in and reset the ecu. The TB screw is turned clockwise to raise the idle or counter clockwise to lower the idle. It works like a charm, trust me =-) As val. suggested you may want to have a look at the throttle cable as well. If the tb screw is not working and your idle is still high (and the cable is adjusted okay) I would definitely look into a leak from the intake manifold, rather is be the TB gasket or gasket from the runners.... Or just a vacuum leak in general.

Everything is in place. No vacuum leaks not anything. With the stock injectors, 800rpm idle. With betas, 1500-2000 from time to time. So my question is still the same. Can the safc fix this???

Yeah it could, without a wideband you dont know what your a/f ratio is. It could just be that far off at idle.... Not for sure though.
