    MAP-ECU2 is always going to give you a better outcome as you can optimise the fuel and ignition timing. Both units come with built in MAP sensors so all you need to install them is a vacuum line and the materials to connect the supplied harness to the car, e.g. solder/heatshrink or bullet connectors. There are a couple of electronic components required for a MAP-ECU2 installation on a 7M-GTE (see the wiring diagram) which we will supply for free if you purchase from our website.

    A word of warning. You might like to check the vacuum with your cams to make sure there is decent vacuum at idle, e.g. at least -18inHg. Poor vacuum can lead to tuning difficulties.

    I read up on the ecu 2 and it had launch control which I really want and it seems a lot more difficult to install I'm newt o electronics upgrading I know engines and I have good concept on reading wiring diagrams I don't wanna get stuck on something I can't finish bc there r no tuners where I live that I know of and what's the best way to check the vacuum and I'm having idleing problems that's y I want this system to tune it good so it will be more streetable

    Your big cams are probably causing the idle issues. A vacuum gauge is usually the easiest way to read idle vacuum.

    It sounds like you are going to need some help if this is your first engine management ECU project and you do not have much experience with electonics.
