wow i had forgotten all about this thread!

With my engine, its a factory m42 out of an early e36, im a lot further down the line with it now!

Its good, but it has no low down power, and its rev limiter is set to low down too imho. Im looking at installing some piper reprofiled cams, i am not sure what to use yet, im asking the dealer to suggest for me, but this will only give say 10-15 brake.

My car is a road rally car here in the Uk, the rules say the motor has to be 4 cylinder, if its 16v then it has to keep the standard inlet, although i do plan to make the throttle flap bigger, and forced induction is banned.

What i would like to do is install megasquirt, and as i have no idea about how to set it up and aparently the problem with megasquirt from a rolling road point of view is that you have to set every last bit up as compaired with say a DTA system that just needs mapping and tweeking, i want to get a base map that i can run my motor with first.

So, can i do this with the help of you kind persons on here?

thankyou!

You can map MS on the road very easily. Scroll down to "VE analyze live".

If i was to buy a ms system, which is best to get and exactly what do i need to get?

I am planning on using the standard loom and making a plug to the cars loom. So if i do this i will be able to download a map from someone here and get the car running?

thanks

I've megasquirted 2 mercedes so far, one with MS1 and one with MS2. For the M42 I would use a V3 board with MS2 daughter board. It will work with all the hardware you already have on the car such as the crank/cam sensors, temp sensors, coil on plug ignition and sequential fuel injection. The main advantages of MS3 is that it can do sequential fuel injection for up to 8 cyls and it has an SD card slot. Otherwise both MS2 and MS3 have 2 16x16 fuel tables, same processor speed, etc.

Scroll down.

If anybody need's the stock maps from the m42 I don't mind sharing... cheers!

Do you have the stock ignition table for our M42's?

I would really appreciate it if you had a screen grab or similar of the ignition table.

I am running MS2e with great success on my 318is. Ran it NA for maybe 10 months and about 3 track events; definitely had some benefits over the stock motronic, as it could compensate for the different intake, injectors, exhaust, etc. Also got me 1-2 mpg higher mileage under most conditions once I got the tune right. Still working on getting the tune with the turbo perfect, but it isn't bad.

BMKIWI, I would post screenshots, but the ignition table that I am using is a little, ahem, unique. when I was going about getting my initial timing values and crank sensor placement, the values corresponding to the actual position of the sensor literally did not work. So I'm running a best guess of crank position, with the ignition tuned based on that. As such, all of my values would be off by some constant factor...

Thanks gearheade30. Sounds like you have a turbo setup where i have an ITB set up on a Link ecu, not megesquirt. So its more than likely to be different in a number of ways!

I intend to set up a safe base ignition map for basic running and tuning however if there was snap shot of a factory ignition table out there it would really help determine if my guesses are any good.
