Is there a how-to on installing motorala 2.5 bar map sensors?

Thanks

I am not sure. I think if you search it it will come up. I have had one on my car for a while, it works great. I used a datalogging cable that plugs into a 4 pin header and some random ecu pins to wire mine up.

I will see if I can find the data sheet for you.

here is the link to the data sheet from digikey.

pin 1 is Vout
pin 2 is Grnd
pin 3 is Vsignal

And pin 1 is marked with a chunk like missing from it on the leg.


He is an archived thread with everything you need.

Thanks for all that information.

Two more questions:
1. Whats the best way to mount it? Any Pictures of this?
2. You hook up the wires 1-3 but dont do anything with 4 and 5?

Thanks

It is recommened to mount it inside the car. Since it is fragile. The sensor is made to be on a PCB, but I have mine just zip tied to a clutch line....

You don't do anything with 4 or 5.

But if you direct a long line to it, wont its measurements be off?
As in, wont there be a delay time at throttle pulls?

There shouldn't be too much of a delay. Just don't run the vacuum line that far.


That is how the megasquirt works, this is the sensor that the megasquirt ecus run, and all those ecus you have to run a vacuum line inside the car. Ihaven't heard too many ill effects of doing it this way. Jus don't make the connection a tiny one, like the one from the FPR, get it off the back of the manifold. Like the Purge Control Valve.
