Quick datalog I just did. Tweaking things as I'm posted this.

Also noticed that on my TS gauge display, the AFR gauge doesn't move when trying to start the car and the Duty Cycle 1 gauge registers very low numbers, less than 10%. Is that normal/OK during start up??

don't use lambda sensor output while trying to get the car started.
Go by pulsewidth, smell and hearing and datalogging.

map sensor is connected to where?

MAP is manifold pressure tube running to the MS correct? That is connected at the inlet to the intake manifold. Reads around 80 to 100 kPa usually.

What do you mean by lamba sensor output? Is that the O2 readings? Also, when you say pulse width, do you mean on the gauge readout or in the tables? If tables, which pulse widths? Thanks.

Also, tried giving it some throttle while cranking and it didn't seem to really make a difference.

I was looking at your datalog and notice accell enrichments going on when you were under cranking, disable AE by putting a huge number in map threshold, like 1000 or 3000 instead of the 50 in there. You don't want it adding fuel like its doing when your under cranking

when is it reading around 80-100kpa?

ITS ALIVE!!! but not from working with the msq I have been using.

Ok, so I tried messing around the the msq that has been discussed in this thread some more last night and was not getting anywhere. Got really frustrated so I loaded the 1st map on the page below.

Megatune Files - Miata Turbo FAQ

Started right up. Did some quick fine tuning on the ASE table and VE 1 to get it to run a little smoother and display richer AFR readings. I didn't care if it was running well, just didn't want to damage anything. Anyways, ended up being able to take it out and follow the FM guide to breaking in the rings.

Did run into a couple issues though. On the way back it was running really hot so I shut it down. Found out that the fan wasn't coming on. I have a reroute and have removed the front water neck/thermoswitch. Thought I setup the MS to have the fan come on at 200F but no go. Is there a walkthrough on how to set up the fan operation? I only have the driver's side fan hooked up at this point. Also, after a while the wideband gauge would stop displaying readings. If I took the key out and reset, it would start up again. Any ideas why?

And in the long run I need to get these things working prior to tuning,

-AFR readings on TS
-Tach in gauge cluster
-Water temp gauge in gauge cluster
-Interior lights. I removed the dimmer switch, is there an override?

gotta check what output you have it on in your current map, make sure it matches your physical circuit/wiring.

Any chance you can tell from looking at a picture of the harness wiring?

Also, I set up the fan control per your directions in this thread below

https://www.miataturbo.net/megasquir...f-65734/page2/

Didn't get to the 2nd page though where those settings changed and it worked for the OP. Might make those changes and see what happens.

Another item, currently I have the AEM UEGO wideband wired to the ECU from the 0-5 Volt Output from the wideband connecting to the RED-BLUE wire in the OEM harness.

The AFR gauge is reading values, don't know how accurate yet, but TS is not registering anything. Is this a setting that I need to change or have I wired something incorrectly? Thanks.

Got the fan working this morning. Followed the directions on the 2nd page of the thread I posted before. Change the X2 function to fan control and it worked. Just have to input what ever temps you want the fan turning on and off at.

Ok, down to 3 items I would like to figure out. Any help would be greatly appreciated. They are in order of importance.

AFR not reading on TS - I am getting AFR readings on my AEM UEGO gauge but not in Tunerstudio. Have the 0-5 Volt output from the AEM gauge wired to the red/blue wire in the OEM harness. Is my connection just poor or am I wired the wrong way?

Tach not working - Switched to COP's so I lost the tach signal. Tried the 1k resistor from IG- to B+ in the daignostic port today and didn't work. Any other options for this?

Interior lights not illuminating - My cluster and all my gauges don't light up. The cluster is wired per OEM, the gauges are connected to the red/black wire at the hazards switch. I got rid of the dimmer switch for interior lights, without it does it default to off? If so, how do I fix that?

Thanks guys!

Anybody have ideas for the AFR reading and/or the tach signal?

https://www.miataturbo.net/megasquir...my-tach-18670/

Found this thread on the tach signal not worked. Does the MS1 come with the tacho output pin set to X2 (JS0) standard or is that not typical? Thinking of checking that in conjunction with the resistor mod.

Does anyone have suggestions on how to get the MS to read the AFR output? I have it connected to the AEM wiring instructions to the OEM O2 wire but the MS still doesn't recognize it?

Problem TS settings? Wiring? Harness?

So I kind of let this go for a while so I could fix other issues that came up but now I'm trying to figure out how to get my tach working.

I have run the car with stock coils and Toyota COP's with the MS1 ECU. Neither get's a tach signal on my cluster. I have tried the resister trick in the diagnostic port, nothing.

Is there some way to diagnosis this? Is it something with the ECU that could be getting in the way? Thanks.
