Start Up, Test Drive & Auto Tune Activation - ME221 Install Pt 03 | Supercharging an MX5 Miata Ep 11

Описание: ME221 ECU Install Attempt 02. As some of you may have seen, the first attempt (   • Basemap Upload, Sensor Calibrations & Star...  ) was cut short by voltage regulation issues. This meant that the standalone ME221 ECU had to be benched until I found a workaround. That workaround took the shape of a Mk1 NA MX5 alternator which was swapped into my my car in the last episode (   • Alternator Replacement - Mk1 NA into Mk2 N...  ). As the Mk1 alternator has an internal voltage regulator I hope this modification will bypass the issue with my 2nd hand Gen 1 ME221 PnP ECU, and allow me to safely start the car without any over charging issues. If this is the case I'll then be going back into the tuning software (MEITE) to activate the LTT (Long Term Trim) auto tune function. This will permit the ECU to make small adjustments to fuelling to get closer to the Target AFR figures. In order for this to work the car needs to be driven around at operating temperature - sounds like a good excuse for a test drive!!

If everything works as it should this build will be officially back on track..

The ECU in this video is a Gen 1 ME221 (black board), but this procedure will also apply to the Gen 1 ME442, AND the Gen 2 ME221 & ME442 (white board). Many parts of this video will also be applicable to other popular standalone plug & play ECUs for the MX5, for example, the Megasquirt MS2 & MS3, and Speeduino boards.

The car in this video is my 2001 Mazda MX5 - the latest Fast Rust project car. Fun & reliable daily driver is my goal for this iconic sports car. If you want to follow along with my 'Miata Journey’, check out this playlist:    • Mazda MX5 / MIATA  -  Budget Supercharged ...
