simtek wiring q
 

as title im about to fit my simtek i want to know what wiring to wire the act sensor upto and also where is the map sensor and will it need changing?

From your name I am guessing you own an STi8, the wiring for the ACT on this model is MAF plug wires 2 and 4 from either end of the plug. Map sensor is a factory 2.5 bar absolute one fitted on top of the throttle body, will only require changing if you intend to run more boost than that.

im looking @running 1.7-1.8bar :thumb: so which one will i need martyn?

There are many you can upgrade to, the cheapest option being the GM 3 bar map sensor. We stock these and sell them for £75 + vat and delivery, I can also include a wiring diagram although once wired it will need scaling for immediately or it wont run.
