Electronic Boost control from unused wire in loom
#41
The 1.6 has a few pins that go back to the ECU that you could use for the boost solenoid.
AFM Connector Pin
1 4P
2 4O
3 SG
4 4K
5 GND
6 GND
7 Fuel pump trigger
You can double check with a multimeter.
Could also use the purge solenoid wiring on 4X or the power steering switch wire on 1P.

How would you check this with a multimeter? Would I enable the switch in MS and check for 12v at the wire or is there another way?
I've currently got 4K pinned for my boost control source but the wiring diagram I linked shows that it's also used for the TPS. I also have my GM air temp sensor run through my AFM harness so those pins are also used.

So I got everything in the car and moving. Setting up a decent target boost map was somewhat challenging. Open-loop stuff to start and I may jump into closed-loop PID settings later on.
Any input on torque curve? Load looks pretty linear and transmission safe to me. I may try to push this little 1.6L a bit harder in the future, but 12lbs pulls pretty good. Enough to make 1st gear somewhat useless.
