Anyone know what type of iac valve an Na6 uses? Im not familiar with iac's so i cant tell by looking but it will help me diagnose a few things on my LinkPlus.

Thanks,
Dann

this should help: http://www.miata.net/garage/isc.html

It's a PWM valve, certainly not a stepper or on/off valve.

Damn, im trying to work this out but i dont think my Link Plus computer can control that PWM type iac's, just steppers and solenoid types. Anyone know if theres a cheap solenoid or stepper vavle that can be stolen and used on the factory throttle body?

The solenoid option would be worth trying, I'd assume it would be dríven using PWM anyway?

Im not certain im still trying to work it all out, I think I might admit defeat and buy one of diyautotune.com's stepper motor kits that just hooks up with a nipple before the butterfly and a nipple after it with vacuum hoses in between. Any alternatives? any throttle bodies with a stepper or solenoid iac with a variable TPS that bolts to an na6 manifold?

don't know what type of stepper motors are used, but alternative variable tps tb discussed here: viewtopic.php?f=29&t=41201
