Where are you guys grabbing the power for the MAP sensor? The other site that I saw linked to says take power from stock MAP sensor. However I didn't locate a MAP sensor on this... and it needs a 5 volt supply.

I believe this car is DOHC JDM turbo engine on non-turbo ECU.

hmm when i hooked mine up you just needed a 12v power source 2 grounds tps wire and then you had 2 wires for the maf sensor 1 that ran form the maf to the safc and then one from the safc to the ecu.

It's been so long since I used SAFC, the two grounds, brown is closest to the ECU... but what ground is it they are connected to, VAF??

I'm trying to use a MAP sensor in place of the TPS in order to get a linear range seeing as the TPS is only on or off. As per this that was linked on here a while back.

I have the same sensor as mentioned on the site, but not the same car obviously. The map sensor needs 5vdc power supply, is there anything that gives 5 volts on the MX3?

Ended up using the bl/gr ground going to ECU as it looks like that's teh ground the other sensors use.

Either going to try a MAP sensor from another car that takes in a 12 volt and outputs 5volts, or use a voltage converter, or... use stock TPS.

How much look do you guys have tuning with just the on/off of the stock TPS?
