Is it possible to run a Megasquirt ECU with all the standard sensors on the car? what version of the megasquirt hardware would you recomend to get?

Is there a comprehensive guide for setting one of these up on a cinquecento?

Cheers all.

See the ginormous megasquirt thread.

Otherwise, Kripit and Arc will be along shortly, perhaps even Asteris, all the way from Greece!

From what I remember, you will need a wide-band lambda, otherwise, most of the stuff can be made to work.

read what i said on your other thread... as far as i know MS is set up to run on ford sensors but you just need to calibrate them using a thermometer.

MS2 board version 3. http://www.glensgarage.com/catalog/megasquirt-ii-ecu-kit-v30-p-31.html

If I was you I would also raid a mpi punto or something for its head/injectors/pump

yes, i use an MS1 with a V3 PCB and run the ms:extra firmware. For a new build i'd recomend getting an MS2 processor though.

im also using a MS1 v3. only different sensors i have is the wideband lambda and the throttle position sensor

may I ask why?

ITB's

nice! got a pic?

Hmmm ... so u can build the MS, then plug the orginial loom in.

Then just set the volt of eah sensor in the laptop ?

not so much "plug" it in.

remove stock ECU plug;



trace wires;



discard excess;



wire up (thats a relay board)



relay board connects to this;

way to put him off arc ;-) (almost putting me off doing it!)

The way I run my wiring on the N/A Sei is stock loom into the gutted ECU box, that I've added another connector to which goes to the MS2 under the dash. Either way you'll need to trace all the wires like arc did or get an accurate pin out for the ECU connectors.

I'm running an MS2 V3 PCB with a narrowband lambda & it's working fine on my lightly tuned Sei, somewhere down the line I'll get a second WB lambda (2 cars & 1 WB lambda sensor doesn't really work). That said for mapping you'll need a WB sensor, especially if you're mapping at home rather than on a rolling road.

I was going to do that at first but I now have another cinq that is going to be stripped out. so I may as well make a whole new loom.

seems to be quite a few of us with megasqurt now. wonder if we could have a thread where we put just the settings and maps we use.

Did you use a wideband to tune the map then swap to narrowband to keep the fueling around idle good? (as a stock ecu would)

Yeah, mapped with a WB runs on a NB. As I said I've only got the one wideband sensor right now & it seems a better idea to keep the WB on the turboed car as it's more sensitive to fuelling problems.

Im going to be buying a megasquirt but will everything else work like headlamp leveling, tempreture gauge, rev counter, speedo, fuel guage?

Will everything in the car still function or will i loose the functionality of the guages?

Cheers all

the only thing listed there that is driven by the ECU is the rev counter, and support for that can be easily added to MS.

is there anything you know of that is driven by the stock ECU that i will loose the functionality?

Cheers

ahh oops.

erm. no.

:doh: we do, its at the top of the technical section, called megasquirt
