1996 Mazda Miata M Edition

Under duress from @beermoneymotorsports I'm forced to make a build thread for the Miata project. Since the car is "finished" (lol) I'll be starting with that and a few highlights then maybe expand from there. 1996 Mazda Miata "M Edition" 1.8 with .020 overbore Supertech pistons (...

In case anyone wants DFU to install firmware instead of st-link, short boot0 to 3v on startup. Mine had readout protection enabled, so I had to "Read Unprotect" (AKA erase) before connecting

Zach are you saying you know OEM connector part number? Is that something we can document at https://github.com/rusefi/rusefi/wiki/OEM-connectors?
Haven't physically verified but I'm pretty confident that this is the factory connector

Re: Audio output

Unfortunately, this doesn't really seem like a particularly useful feature to include in an ECU. If such a feature is desired, you could probably accomplish it using an external buzzer module and use https://github.com/rusefi/rusefi/wiki/FSIO to trigger a pin under the specific conditions that you'r...

Re: How to get started with Honda

I suspect that FSIO got VTEC software covered. Is it a high-current high-side control? I remember we have added a weird custom high-current high-side module for my short term Accord test mule but do not remember if it was VTEC or something else. For your Accord I think it was probably for variable ...

What are your problems with the 9926? Is this that low tooth count issue? I understand many honda's have a 3rd signal. Also is your signal a VR? The math has probably been beaten to death here, but if I'm correct I need to be above 350rpm to beat the 85ms watchdog with the 4-tooth cam wheel, and ov...

No VBatt because it's not configured in his tunerstudio project, and I'm assuming it's not hooked up.

Re: Nissan on Frankenso #47

I'm pretty confident that setting the IAC to 0 will not solve anything, and may cause additional problems. My recommendation is to change your VE and ignition tables back so they do not cover your cranking range.

What is your AFR while cranking a cold engine?
