Hi from new Zealand

Hi Ive put a Ga16de engine into my Micra K11 and boosted it. I was looking at management for a while and came across a megasquirt ecu. Megasquirt ms3 with daughter board max I think it is . It's on its way to me . Not sure of what functions it supports yet or its capabilities. Something to learn from . I'm hoping to go mafless and bin the distributor and use cops and cas set up .

My first question would be is the internal map sensor good for boost as when I was looking at speeduino it was advised to go external. Also the iat sensor does it have to be a gm sensor or can I use the iat from a Subaru?

On board sensor is an absolute 2.5 bar sensor so it can read up to 1.5 bar positive boost so up to about 20psi from the turbo is fine above that you need another option. Iat from a scooby should be fine as long as you calibrate the thermistor tables to match. Mad delete should work fine using speed density and coil on plug will be fine as long as they can be triggered by 5v logic signals ( eg have inbuilt ignitors )

Cheers what's the 3 red LEDs for on the outside of the ecu? I was kinda of expecting it to be for power?

Also how would I no if my cops had on board ignitors or not? . The ecu was configured for a 4age engine before I had it . It's set to run cops I just don't no if I have the right ones

The answers to these questions are covered in the Hardware Manual.

Thanks for your reply.

I bought the Ms3 second hand. It was configured for a 4age cops. As silly as this may sound it said in the sale the the Bosch ignitors will be removed before sale . I'm hoping it's nothing in the ecu that's been removed. I wouldn't no what the ignitors look like in the ecu.

Also abit dubious about the ecu as most manufacturers ECUs I can find lives and grounds and get on with it. All I've got here is what looks like one red wire with a label on it for ignition power it says and a chunky looking eyelet with grounds going to it . I'm assuming here I'm gonna need the tunner studio to check everything works . I assume the external 3 leds on the Ms3 was for power as nothing lights up
