    This has been a project in the making. But it’s come to life. No more stock ecu. No
    More hard limits. Pnp harness is what we worked on. I was able to get my hands on the first or 6 kits being made. Here are the results with a short day of testing. Baseline on base tune of wastegate spring pressure I made. 557hp

    Then a couple pulls later 793hp and we are calling it good here to get some track data. Turbo is good for 900 or so. So we will see how she does and if track can hold

    Now onto the good stuff. This ecu has mazdaspeed 3 firmware on it. What’s that mean? It means it connects to the oem can bus. So you can still your stock instrument cluster, stock sensors, stock abs system. Whatever your heart desires. Or just delete it all and run just the motec and a pdm [emoji8][emoji573]

    Not cheap lol. Looking like 6895 which is on par with what they charge for the FA wrx and new civic type r that has same setup.

    Haha didnt think it would be reasonable. But thanks for finding a real solution to people that will pay that much to play. Can't wait to see where this advances all the high horsepower guys

    Ok, you have my attention. The price isn't bad considering...

    Forgive my ignorance, but is there any benefit to us fruit cakes that dont want 700+hp?

    Maybe a way to fiddle with the DI system for slightly more fueling?

    I'm drooling at the idea of revving out to 9k rpms, but I dont know if there are any other pro's for us guys under the monster power crowd.

    Edit: some more questions came to mind...

    Would we be able to use this standalone with a FlexFuel sensor system?

    Would the gen2's be able to do permanent SWAS delete?

    Could we control 5th/6th port or even 8th port PI directly with the standalone?

    @Mauro_Penguin

    Yes this replaces the need for the split second controller for aux 6th port/PI!

    I figured it would, the info I tried to find on the standalone made it seem like it easily should. I just dont know what will be required for the plug-in harness.

    Not to mention you wouldn't need a WOT Box anymore either.

    I guess this Motec opens the door to rolling antilag too :hearteyes:

    So do any of you guys know of we can use a flexfuel sensor to run e85 mixes with this thing?

    I know @Atvfreek is a busy guy, but I'm curious about all my other questions.

    If this thing can truly delete SWAS, run a flexfuel kit, squeeze out more DI injector room, and rev out to 9k rpm's.... I'm down!

    I'll be caught up on my credit cards in the next couple of months, so cost wont be a problem if it can do everything I'm hoping it does.
