this is the one for the five knob i need the one for the single knob. i need to know which car setting i shoud use?

That single Knob SAFC is useless for a DSM, I almost bought one looking for a deal but although it'll hook up to your car, it won't give you performance gains except for that one RPM incriment you choose. This unit was best suited for a RX-7.

well i use to have it in a rx7 years ago now i just had it laying around doing nothing, so i decided to install it but ran into this problem of not having a manual. so i don't know what car setting to put it too and to check if i hooked it up right.


any afc guru's out there

Find something else to do in your spare time. There's no point installing something that's not going to be useful.

sell it to a guy with an RX-7, buy a 5knob or new afc, and then start tuning....its not beneficial enough to use...hope this helps..latez

this car is a winter beater just trying to get some extra out of free ####
and for the record it does make a diffrence. what do you think people were using before the five knob and new afc. when i brought this new it was the best thing on the market

Before the five-knob AFC, people tweaked the IAT sensor output.

The problem is that you're not going to get "some extra out of free ####" with your one-knob AFC.

Typically you want airflow tuning to offset a) larger injectors and/or b) hacking the 1G MAF.

In both of these cases, you actually want to *add* fuel down low to compensate for injector lag time and the funky flow characteristics of the hacked MAF.

You can't do this with the single-knob AFC. If you adjust for a working idle, you run too rich everywhere else. If you adjust for your bigger injectors, you won't idle worth a damn.
