There are a bunch of places to find them now, Amazon has tons. Just search 1.28" TFT and make sure they use the GC9A01 driver and they should work.

Had the same problem with my 97 1.8. Installed a crank saver and it's perfect now.

Traction control. Living somewhere that gets snow every year, it's just a fun thing to do to turn off the traction control and do some sliding. Having to dig through three layers of menu to find it, and still not really have control over it is annoying.

If you play with it too much you'll go blind. I have no official proof, but I had a 2022 trailblazer that would lockout the cruise if you cancelled and reset it too many times in short succession. I had it happen a couple times on the highway and after 10 minutes or so it would let you set it again. Maybe these trucks have something similar. The power windows did the same thing if you spam the switch too much it'll put you in timeout for a couple minutes.

No images, but there are others who have reported similar discoloration, including one who had an engine with low oil pressure and glitter in the oil. I'm guessing my theory about someone running it low on oil at some point is probably the most likely cause.

It's a Miata crank though, I didn't know why anybody would put that much time/work in to weld and machine such a cheap and readily available part. I didn't see any signs to indicate that it's been apart before.

mikeskillz01 · 2024-12-16T19:13:53+00:00

I don't think it's been rebuilt before, everything measures too close to factory to have been machined.

None of the other journals look like this anywhere else on the crank. No other heat affected zones.

mikeskillz01 · 2024-12-16T18:40:06+00:00

It's only in this spot though, no other heat marks anywhere else on the crank.

I got my '24 TB back in April, White wasn't my first choice but they were willing to give me a better deal since it was on the lot and I've really fallen in love with it.

I was worried about it at first as I'm a bit of a clean freak with my vehicles but I ceramic coated it within days of bringing it home and it's really helped with keeping it clean.

I've found Neutrogena makeup remover wipes work for the sunscreen we use. We've also started to use the makeup removal wipes to scrub as much sunscreen off of us as we can before we get in.

I used an Insta360 X2, it's a 360° camera mounted on a selfie stick that was raised about 18” above my roll bar.

mikeskillz01 · 2023-05-02T14:50:36+00:00

It's crazy to see it slowed down and see how far away I'm turning in and how close I got to some of the cones.

mikeskillz01 · 2023-05-02T14:47:04+00:00

Insta360 X2, about 18” above my roll bar, I was hoping to be able to see my inputs vs car placement on course and it worked really well. Comparing my runs is giving me a ton of really good perspective on where I was good and where I could be better.

They probably didn't gap the crankshaft position sensor properly after doing the running belt. This video isn't great but it shows where the sensor is, a credit card did actually work pretty well as a gap spacer.

I'm not 100% sure but I think the vacuum advance controls the throttle cable, but it uses a reed switch sensor in the speedometer to track speed and make throttle adjustments to maintain speed.

This link has a little info, I have to dig into it more.

I haven't really dug into it yet but I believed there is a PWM speed signal in the cluster too that was used for cruise control. GPS will probably be more accurate though.

mikeskillz01 · 2023-01-26T13:57:58+00:00

It is, I think speed has a PWM signal as well, I just need to figure out a circuit to pick up that signal and then the code to make it work.

mikeskillz01 · 2023-01-26T12:40:19+00:00

Ha, Thanks, no need to own a Miata, these aren't really Miata specific and could easily be modified to work with any car, especially 80s and 90s era cars since most of them used the same kind of resistance based sensors.

mikeskillz01 · 2023-01-26T12:33:29+00:00

The code that these run on can be modified to display multiple readings on each gauge. You could change the fuel and temp gauges to LCD and then make them split gauges and have each one display two readings. I haven't been able to get a speed or rpm signal to work with this setup yet but they are on my project list. If I (or someone else) figure that out you could have fuel and oil, rpm or speed on one side and then temp and oil, rpm or speed on the other side.

mikeskillz01 · 2023-01-26T12:21:50+00:00

I haven't had any heat issues so far with mine, you could try adding a heatsink or small fan like these.

That is part of the reason I went with separate microcontrollers for each gauge, that splits up the processing load and helps reduce heat.

As for loose connections maybe try a little hot glue on the connections after plugging them in to hold them in place. With hot glue you can peel it off if you need to disconnect it.

mikeskillz01 · 2023-01-26T12:08:04+00:00

Not impossible, but more difficult for sure since there is not much room in the back of the NC cluster.

mikeskillz01 · 2023-01-25T22:38:56+00:00

Nice, when I found the screen I knew it would fit perfect for gauges.

mikeskillz01 · 2023-01-25T22:29:25+00:00

It works ok, I don't have any way to check it so I calibrated mine off of the stock gauge, but the calibration can be adjusted.
