MAF signal switch

Post by Neno »

Hi,

I didn't know where to post this so I chose this area.

I have to built a circuit like this to fool my stock ecu. I'm using MS2 but keeping stock ECU because of the electronic throttle. I've tested this using a regular switch from the cabin and it does the work. (no more mil indicator when engine goes on boost). Now I would like to do this kind of switch using fet transistors that are controlled by one of the MS2 spare ports (like fidle over tip122 that I'm not using at the moment).

Can someone give me an idea of how to arrange this.

Your best bet would be to use a 5 pin relay to handle the switching.

That was my first thought. But considering the amount of clicking that this relay will do I was thinking to go with something without mechanical parts if possible.
