ecu

Anyone play to Megasquirt ecu?

More people say very similar Motec ecu and very cheap.

Anyone experiencies?

allot of "amateurs" brag about them, but talked With my enginebuilder, and he was far from impressed With them... it is possible to get to work, but far from as good as a proper one...

ive built 2 megasquirts and eventually got got my engine running on one of them, though didn't get it mapped in the end.

building one is a marvelous educational experience but if you want to try and use it real world get prepared for lots of reading. also consider that the general build quality will be somewhat less than a commercially available product.

you can configure them in an endless number of ways and whilst that makes it of appeal to a larger number of people, its also one of its biggest downfalls. the ms2 for example has 2 injector channels which can run low Z injectors. however, if you are running big low Z injectors you will want 4 injector channels. you can chop the ms2 ecu board up to do this but that introduces other issues.

another problem is the fact that it has a crap dsub connector on it which only has 37 pins. the connector is actually a parallel printer data connector so the pins are little and since the ms2 has to potentially ground 4 coils and the injectors and any relays etc they have allocated about half of the 37 pins for grounding. so you make another hole in the box and add another 25 Dsub connector for more input / output and try and find somewhere in the box to run the heavy current wires away from the signal parts. you can see its really an experimental device although lots of folk do use them real world.

if you have a fairly basic requirement of the the ecu and on a budget it may be worth considering but i couldn't see that its a viable replacement for any weber marelli ecu. as said earlier, its a great way to learn how ecu's work.

they now offer a commercial quality fully built unit called MS3Pro which im considering as it looks really good and has a feature which Ive not seen on any other ecu's available at any price (correct me if Im wrong). that is an app 'shadowdash' you download to android which you then use as a dedicated device for your dashboard (great for kit cars etc). you can easily design endless dash layouts to monitor any ecu functionality - it really is a very cool thing. its blue toothed from the ms3pro so no cables. the problem is the ms3pro is £1100 inc harness.

another interesting low cost option is VEMS which is a very comprehensive unit and works out about £600ish inc harness, 4 low z injectors, 4 coil drivers, map sensor etc. it can also recognise stock escos crank / cam signals

i hope the above helps!

Hello friends.

Thank you very much for the answer.

Some friends say possible 2 als maps and can be less consumption.

But for me it is enough with my P8.
I think it works fine.
I wish only to Roller Ecu inside the car, but can not possible in spain

I'm currently running my st Escort on the Megasquirt 3 for a few years now and have had no reliability issues. In fact the only issues I've had was related to the map. I finally had the car mapped about a month ago making 400hp/320tq at the wheels with 20psi boost. I did run into a boost issue on the dyno but later found it to be the wastegate not closing properly.

I've used a cheap German copy for some year. Hardware was SMD and the only Thing was too build it in the car. And after 2 year I've a functional map with araund 270 on the wheel . Nex step is MS3Pro because the German guy dosnt't make a good Job. But I would say ist works good when you do it right and make a good map.. 2 time the Motor was killd by writing wrong Software. But you get VE Autotune that helps a lot. But you need much work for Information. And some extra stuff like WB Controller and very importend oil Temp () and EGT.
