    How To - ECU Replacement

    Hey there Mike sounds like a whole lot of not fun!; Unfortunately you cannot just drop the new ECU in there after doing the key procedure as you mentioned, as the HEC would then no longer be able to communicate with the new ECU without adding it to the car with IDS.

    Sorry for the ridiculously late reply, been moving and changing jobs and haven't had time for mazda things :( @takotomo nailed it, Forscan is useful for some things but not this procedure. I recently purchased a ford focus rs and started using Forscan there to program things like seatbelt...

    Here's a video clip of the car idling and me mashing the gas a little bit. I still had two step set up at this point so you hear it break up a bit just shy of 3k but you get the idea on the rest hahaha. Good luck man https://photos.app.goo.gl/v7mBwcbjJUZAAf7r5

    How To - ECU Replacement

    Yes and yes! I could get the motor to idle if I kept on the throttle a bit but it idled like absolute shit. On the AP I was getting the expected in-tank fuel pump pressure. Giving the solenoid on the hpfp 12v gave it all the pressure it wanted so it had to be either the wiring or something on...

    How To - ECU Replacement

    Quickly looking at that it does look like you could perhaps get the exact same process done with forscan! It's a PATS system so it appears there should be no problem.

    I had this exact problem and it ended up being the connectors inside the end of the MAP harness. During previous troubleshooting, I was jamming bits of wire like a dumbass into the end of the plug to test for continuity/resistance to pcm end of harness and in doing so it spreads the terminal(s)...

    How To - ECU Replacement

    Parents stopped by on their way through so I'm already behind schedule haha. Man I'm garbage with the actual tuning of things! I understand the computer systems and some CANbus shit but as far as ignition timings/fuel mixtures/etc. I'm still very much a noob! I did however recently researched...

    How To - ECU Replacement

    Alright this is going to take me some time to get this all edited up nicely so bear with me. All of this was done in a 2009 Mazdaspeed 3. This will for certain work on the Mazdaspeed 6 and I assume the systems we describe here are identical on the Gen2 platform as well, but it's only an...
