my picture was to be used as illustrative purposes only.
r14 is not installed, it needs to be installed now. I didn't notice that before. |
Ok so I want to make sure I got this straight. Install 2.2k resistor on r14.
Jumper 1J&4s>Input 1 OUT Input 1 IN> PA0 PE1>Relay 1 IN Relay 1 OUT> 1Q Is this correct? |
no, that's not correct.
I'll repeat myself: 1Q > Input1 IN Input1 OUT > PE1 PA0 > Relay 1 IN Relay 1 Out > 1J&4S |

Hey braineack, did you mean:

no, i did not. i usually don't put outputs on input circuits. However, i do tend to put outputs on relays and inputs on inputs.
So the picture of how I wired it is fine just add the resistor? |
my picture is probably wrong. go by my werds.
but yeah. when it's wired to activate the a/c without the MS in the mix, r14 is removed. Since you're sending it back to the ECU first now, you need that pull up. I'm not exactly sure what circuit DIY used for the inputs, but I'm pretty sure that's a pull-up. you could steal one from an unused circuit on the board if you are desperate. I'm pretty sure r14 is 2.2K, but a 1K might work... I'd need to see pics of the top of the board to see what resistors might be unused and able to work. Probably there's a 2.2K reistor on the high side driver circuit that you aren't using. |
How about I pull r 38. It is part of the nitrous driver and I don't like nitrous. the resistor is colored red red red gold and to my knowledge that would be an ideal 2.2 k candidate.
|
i think that's the one im talking about.
|
Ok so I'm going to move the r38 2.2k to r14 and leave my jumper the way I have them and I should be good to go plug into the car and start without frying anything?
|
that's the plan.

Here's what I got I removed r38 and moved it r14. Just wanted to post a pic for reference. |
while you are in there, move the two wires going to 4C and 4D to SG from GND
|
Ok will this add any other features.

it will move the sensor grounds to the sensor ground plane.

Ok accidentally forgot to plug the map in my bad but still no AC engagement.
Edit Msq found here https://www.miataturbo.net/megasquir...-my-msq-74292/ |
and you've made sure to setup the software for the correct inputs (PE1) and outputs (PA0).
|
Got it to kick on now I guess I need to play with the idle and closed loop settings.
|
This is such a pain in the ass. Do I have to use Closed Loop because PWM Warm up is easy and I suck at closed loop.
