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. |

Not that I've ever heard of anyone having a problem before, but the DIYauto valve is only rated at 122f/50c.
if you dont have one, youre dumb. |
Brain, what wire do you use for EBC in the AFM?

So how do you get K to work without interfering with the TPS signal?
|
why would that interfere? do you have an automatic?
|
They are connected at a terminal, according to the schematic I have.
|
I don't have an automatic but I do have a VTPS hooked up there that I believe is using the 5v reference wire.
|
look at the wiring diagram again. you have 5vref wired to 2N. you dont have an automatic, so it doesnt matter about 4K, that wire doesnt go back over to the throttle on your car.

Does the red line not affect the TPS signal from the AFM connector and 2K on the ECU pin?

Quality penmanship fo sho.
I cut my image off too early. :( Thanks for the help. |

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. https://www.miataturbo.net/attachmen...ine=1455467492 |
