Well, I was finally getting some progress on stabilizing the idle, the afr reading was working, surprisingly. after I few restart the car just stop starting up... And I tried everything to reset the ECU, update the board again, reset all setting to the NA6 MAP reset, doesn't work... Below is what I ...

Yeah, I found that AFR is weird too. I don't have a wideband O2 sensor yet, isn't there a stock O2 sensor that comes from the factory? Or I have to get a wideband sensor in order to have the AFR reading to be correct? Another question is do I have to have an accurate AFR reading in order to tune the...

So, some progress today, the car started when I reset the tune to a preset, NA6 Miata MAP. However, the car was running poorly. Some black smoke came out from the exhaust. The idle speed is around 1400. I tried to mess with the VE table, doesn't work. I've uploaded the tune and some data log I did t...

OK! Forget about all the nonsense about the firmware update, I got it fixed! It was a missing driver. I installed an STM in DFU mode driver then everything is good. I did the update, but the car still won't start up. And here is what I see. no pin cl coil#1. Another hardware issue?

I did that multiple times already. I can connect the board to the console but still, can't update the board. The console I'm running is 20210523 rusefi_bundle_mre_f4 version. I chose auto DFU when I tried to update.

Hi! So, my board is Miata NA 48 pin board for MRE. I installed the drivers embedded in the console, but I can't see a DFU device in the device manager. I do see a "other device" catagroy that contains STM32 Bootloader. Where do I download the proper DFU driver and the latest version of the...

So I downloaded the correct version you posted yesterday and it not letting me connect the board using the console. And still doesn't allow me to update my firmware. Attached is the error I got from the console.

Just did.

Hey guys, so I was messing around with the Tunerstudio and trying to get the autotune working. But suddenly the car just won't start. Attached is the message I got from the Console. I had the updated ini file loaded in the Tunerstudio, but the firmware version on the ECU is still at 2021/3/14. So I ...

My problem here is I can't change the numbers in the target AFR table. The number was stuck under 1.5, I can put 0.8, 0.9, etc. but nothing above 1.5 I wanted to use the autotune feature, but I'm not sure I can use it with the AFR table like this. From my understanding, the autotune will adjust the ...

So, I received the ECU yesterday and tested it on my car today. The car starts and runs. The idle speed is stable at around 1k, but I can tell the engine has more vibration than nomarl. So I checked the AFR which is running at 16.7 which is too lean (I believe). As I was trying to do some tunning to...

I'm in Miami. Yes, I can! I want to get it fixed soon! Wanted to have her on road for so long
Can I have the shipping info, if you want you can send it to my email: cheerioov2@gmail.com
Or post it here, either way, works for me. So am I missing a resistor or something?

Was a really busy month :( Anyway, got everything you guys needed in the link below, the screenshot of the live message from the console, and pictures of the ECU. https://drive.google.com/drive/folders/10nUBpB3unESy6rJkX8h3RRYySGZPItXc?usp=sharing I don't know if I did the tune upload correctly, but...

Thank you so much for your guys' help, I will send everything you need this weekend when I get back from New York. I was traveling with my girlfriend for the past week . I was really surprised that NA Miata has a TPS tho haha

So sad :( , I was really excited to test the board. Sorry for the late reply, last week was crazy busy for me. I still want to use the ECU, I want to ship it back to you and get a replacement. I have no faith to do the wiring myself :lol: . Can you send me a shipping label on eBay or here? Or my Ema...

Some background info, it's a 1993 auto Miata. I swapped in a manual transmission. Got a used 1990 manual ECU on the car. Run&Drive but idle at 2000rpm+ and fluctuate. (I tried the manual adjustment on the throttle body, no luck there) So I figured it might be the MAF sensor doesn't match with th...
