Is the polarity of the cable correct? I know you get an error on Megajolt if the polarity of the crank sensor is incorrect. Then the next step is checking all the earths are good and without interference.

Its times like this that make a carb and a set points look very attractive

ok lets ask a real dumb questions and go trough this one bit at a time and may i ask was it s/h, self built or pre built?

1. does your ecu all work ok on a stim? with a vr input running does your ecu get rpm's, sync and work ok if it dont its not going to work on a car! (recheck it)
also have a look at the tooth logger in tuner studio
2. on a ms v3 pcb there are 2 pots to ajust the vr circuit there is a bit in the build manual to pre set them before making running ajustments this may get it going on a stim or on the car
3. what restince do you get between the two signel pins of your pick up (not cranking)
4. with the vr sensor conected directly to a multimeater in V AC what voltage do you get (whip the plugs out to get it spinning better)

do thease bits and we can go from there

rob if your totally at your whit's end and feel like binning the lot send me the ecu and the sensor and i will check it out for you foc. having built/repaired quite a few ms's im pretty good at fault finding them now.

I don't normally offer my services out as it am pretty short on time these days but I hate to see someone struggling.

I am at a loss as to the benefits of these megasquirt systems. I was looking on the website and costwise they are not a country mile away from the emerald/dta prices. With that and all the apparent problems most people have getting them sorted is it a good move? The model numbers go on for ever without any explanation as to the functions . The ones I have seen that look any good that are in a decent case with proper plugs are not cheap. Just thoughts and a rant.

Well like ash I don't like to see people struggle I also have a stim to test it if you want to send it to me but before you do anything I would do the bits in my last post first.
If you can. I sent you my number a few days ago to help you get to the bottom of your problems.

I think ms gets a lot of bad press from people who get problems or don't know how it works it is quiet complicated.

If its a pro built unit you could get them to test it for you

megasquirt is one of those things where if you understand it fully its very easy. if you dont understand it, you dont bother and get an omex etc. the issue is with all the people in-between. some get most of it an get by, some dont know how it works but are capable of following the manuals with a bit of outside help then there are people that just go for it because its cheep with no intention of learning anything.


here is the deal.... MEGASQUIRT IS AN EDUCATIONAL EXERCISE (its clearly stated on their website) the ecu at the end of the process is the result of what you have learnt, if you dont bother to learn or lack the intellectual capacity the output at the end wont work.

clearly rob wants to learn and for people like him there is huge network of people over on the ms forums. but keep in mind if you come across as someone that is not willing to learn or too lazy to read what is already in a manual there wont be any help.

and as for value an un assembled ms3 kit with the ms3 expansion board works out at £300. but you have to learn about it and build it!

an omex 710 which doesn't do quite as much but has all the main features like fully sequential, cop support, turbo control features etc will cost you £1000.

personally i would say if you want an off the shelf built ecu the omex is the better option but you will pay a bit more for it
