Im just an average guy with reasonable skills and ive just built this fully working MS2 version 3, it took six hours to solder together and i can see no reliability problems as i payed attention and made sure all my soldered connections were good.
If for the unlikley reason i blow something up (through my own fault of wiring it incorrectly) i can fix it![Top](https://passionford.com/forum/images/smilies/smile011.gif)
This ecu can also be configured for many applications, ford edis, cop's, four cylinder, or v6, v8 or any number of cylnders for that matter! turbo or NA can all be ran off of it, the possibiltys are endless.

The car is now running and i have been for a drive, a bit of tuning to do but the results are good. It has cost me £250 and around 12 hours work.

lol, a bit of spiro wrap and it will look top notch ![Wink](https://passionford.com/forum/images/smilies/icon_wink.gif)
I bought this as a kit for £210 delivered off of ebay
thanks, yeah you have to be carefull, if you blow up your ecu it will be costly! (ive blown up a ms before, incorrect wiring, but i managed to change out the components that i cooked!)

thanks all for the possetive comments, it runs edis as i didnt want the added hassle of making extra circuitry to control the cop's, plus edis does not need the dwel and vr sensor setting up and so in my opinion will make it that bit more bullet proof. I was using the edis to control the two wire cop;s, but that proved problematic so i have now switched to a more conventional coilpack and leads.

i now do that sort of stuff for my day job, but its mostly surface mount stuff, i can hardly see some of the things and you need to use tweezers to pick the caps and resistors up lol.
good job tho my man. my downfall in doing something like that would be the mapping lol
only downside i can see is that its a bit on the big side, if it were surface mount its would be less than half the size, but also a fair bit harder to solder

Good job on the soldering ![Top](https://passionford.com/forum/images/smilies/smile011.gif)
this is what i love about MS its the learning experience but obviously its not for everyone, when i finally get my locost on the road next year (2.0 zetec on MS) i will be learning to map which is just something that interests me, i can see how its not for everyone though.

TBH, my bird could make the ecu, the instructions are very good, and as for the engine loom its only 12 wires, so again very easy. You just need to either be shown the mapping or read up carefully about it, i was out last night with my mate tuning the fuel map, hehad never seen it before in his life! withing 15 mins we were working as a team tuning.

I run my 24v cossie xr4x4 on megga cum, great learning experience.
found the 24v started to valve bounce at 7k lol
Also I cut the connector off a old ford ECU and connected it that way, so I could just plug it in, or swap the old ecu back in mins

Just back frm some one man tuning (lol) got all the cruise/low throttle fuelling quite good now, the car is very good to drive now after an hors worth of tuning. Next will be to put some more ig advance into this light throttle area and re-assess the AFR, then im going to sort the boost fueling! A few very short bursts of boost shows that the turbo i have chosen spools up well between 3-4k and my actuator is set about 11psi, i will be aiming for nearer 18 psi end result

Have you tried tuner studio? Has a feature called ve analyse live and will help you tidy up your fuel table using target tables etc, i got my st170 engine running pretty hot using it.

I just got the correct wiring pin outs of the 24v loom.
simples, but I still got the TPS the wrong way lol

tps is always a hit and miss with me too lol, i got this one right first time round (sheer fluke!) but its no big deal to change the wires as you know

I was so focused on fuel map(not checking TPS) I started it(the first time) with the tps suggesting full throttle.
it started, but fuck me how much black smoke lol

I always use TPS as a sanity check that the ecu is powered up ok and chatting to the laptop etc before I turn it over, as its the easiest sensor to change the value of and check the laptop registers it etc.
So I turn the ignition on and wind the throttle open and shut to make sure its all ok, before trying to start it, (if its a turbo car I also blow and suck on the map sensor pipe) I also glance at the coolant and air temps and make sure they are both reading about the same and roughly ambient.
Then I turn over with the plugs out and fuelpump disconnected to check the crank sensor, and in the case of MS you often have to play about with the input sensitivity pot to get a stable reading.
Then fire up.

Chip,
If I ever do it again, I agree its nice and simple to check, spotted with in seconds when I was monitoring the ECU dash board.
everything is a learning curve

problem is they have to be specced for a specific application, vr/hall sensor, wasted spark, distributor, cop's, edis etc. i would think there would be £100 profit per ms for a built one
