Flash ECU O2 Sensor Issue

Don't forget to make sure you have good battery power before flashing. Battery charger is prefered.

Going to have the charger hooked up during flashing, however there will be no flashing until I know how to set it up.

You don't use the mits adapter from tactrix, just plug the module into the obd port and the stereo connector from pin 100 into the module.

That information conflicts with what is on this site for the '94-'97: Chromed ECU | 94-97 Plug and Play Flash Ecu Installation

Which is why I have not done anything as far as flashing is concerned, because of fear of bricking the ECU.

*sigh*

You do not NEED the mitsu reflash connector. I think the reason Adam sells that piece is so you can adapt your 94-97 car to have the convenient plug setup like the 98/99 vehicles which use the mitsu reflash connector. It's a clean setup and nothing more. All that cable does is attach pin 100 to the tactrix cable so a 16V source can get to the chip. There is nothing in that connector besides wire. Be it direct or another plug, it goes to the same place and does nothing.

If you brick your ECU, it won't be because of this.

So, unnessesary or not, I can install and use the plug the way it is shown on the website? Just want to double check. Already have the Tactrix male plug.

I use it, but apparently is unnecessary. Not had any issues flashing with a charger connected at all times.

It's a cleaner setup vs what Brett sells with the adaptor harness (not meant to bash, both function perfectly. Adams just looks like stock).

Awesome. Thanks again Greg! I'll work on it this weekend and get that log hosted.

YEs this is correct.
