Apexi S-AfCII for RA
wait can you elaborate plz? cuz to be specific mines the safc2 and what do you mean spend 3 dollars? and make it run? sorry im still new to all of this just started back in jan

Sorry for the confusion... what I ment is that you'll need the 3 dollars to buy the opam, it's base and a resistor to make any safc (mine is a safc2 also) in a RA.
What happens is that the RA ecu has an internal resistance in the signal from the maf (this is different to most cars), so you first need to simulate that load so the signal from the maf is not miss read (to high) because the safc does not has that resistance. Now you need more power (meaning volts x amperes) to feed the ecu from the safc 'cause that resistance will kill the signal. That's the reason for the opam configured as a voltage follower to mimic the safc output voltage but with more amperes.....
But forget about all the technnical explanation....just connect the this as it is described in the thread and you'll be happy.
(By the way the 3 $ was just a number I spent less than 20 mexican pesos that's about 1.5 usd..........and lots and lots and lots of hours and frustration)

mmmmmmm your local electronics store maybe... radio shack has a few opams, but I dont think they handle that one (it is not very common 'cause it uses ground and positive voltage unlike most opams uses positive-negative voltage). The resistor you can find on radio shack.
For shure you can find both it in http://www.newark.com and they ship anywhere, but then youll pay more shipping than cost of parts.
PS. Remember to use a base for the opam, otherwise you'll fry it while soldering (see my other thread).

I sent you a PM earlier (in spanish)... Did you get it?
Take care...
