tim_s .. it is MSVDS Ver 2.13
I am not a MS expert and everything was made by a friend of mine. It is compacter, it fits perfect in the motronicbox. The best part is, that i have everything that MS1 V3 has ... i read from the VR Sensor, Knock, Shiftlight, I can run the Stock M42 Coils and so on ... the best part .. I need only to get s MAP signal to the MS, nothing more, nothing less. The rest is plug n play.
  When I install the knock sensor, I will make some fotos of the whole MS system.
This sounds like a viable alternative and a lot less hassle. I'm all for plug and play. Does the tach, guages, and the rest work as before?

lol at the tree-hitting, that explains a lot. was wondering why the megasquirt project disappeared!

i don't know whether you'll upset the ECU if you feed it the LC1, geuss there's only one way to find out! i reckon it might not - grounds for this are that my uk car (like most uk ones) doesn't have the lambda feedback circuit but has the CO input from the AFM (basically AFM has an idle screw). With no lambda obv there's no fault code thrown, with no CO input nor lambda input there's no fault codes thrown iether, lambda feedback works if there's no CO input to the ECU and lambda hooked up, and the idle is screwed if there's both CO input and lambda input wired in, but no fault code thrown. hope that makes sense, but basically is a long-winded way of saying i think you can get away with quite a lot wtihout throwing a code.

EAE = wall-wetting accel enrich algorithm. think it requires a really good VE table to work, which is prob where mine still needs some work - my ms2 map is pretty new and i've not had much chance to fine tune - need a test driver and some time so i can do some live mapping. it's not really doing what it should at the moment, also think it's throwing off megalogviewer's VE analyser, so no lazy tuning for me!

HR = high res code; you lose capability of running lo Z injectors, but gain better res on pulsewidth and improved battery voltage correction etc.


Yes, I have noticed a lot of play room in the Motronic on all imputs except the AFM lol.  Get that off by more than 3% and it is not happy!

I was always somewhat confused about the accel-enrichments dea;y.  If I am understanding it right, it would inject even more gas when the throttle pedal was actually being pressed then level back out once the pedal was no longer moving?  It was like gas-pedal movement acceleration to richen things up with the new inrush of air/changing air flow rate?

I was unaware that low impedence injectors were better?  Our stockers are ~16 Ohm which is considered high impedence.  Why would upping the fuel table resolution make low-impedence injectors unusable?  You have an edge on me thanks to Mr. Tree!

hi has anyone done a megasquirt install on an e30 318is???
I want to kep the original wiring, i have built the ecu but stuck on getting it to work on the car. i am not getting a crank signal.
someone please help!!!!!!!!!!
