How to convert MS2 to stand alone
 

Picked this unit up for my mazdaspeed swap into 99. Previous owner had it in parallel & don't know what mods are done internally. Can someone tell me what mods are done, just by looking at pics below & what mods I need to run as a stand alone?

unsure whats going on with r6 and r7 and the yellow wires and what/why they go back to in the proto area. I'd replace r6 and r7 with a 1% 1K resistor -- make whenever you ever calibrate the sensors, you change the bias from 2450 to 1000.

otherwise, unplug the stock ECU, add the idle valve PWM circuit, and voila -- standalone.

+ needs more processor

i guess that helps.

After a lil research, looks like am setup for standalone already(fan relay & EBC mods) except for PWM idle mod. I can't find anything about those yellow wires, R6, & R7 maybe its an alternator mod.

Removed the processor for clearer pics. LOL

Thanks, Braineack!
