Custom Plug and play Megasquirt systems

[kowalski]

Overall including the cable connection part it is 7.25 inches wide and 5.75 inches deep...If you are just wondering about the box itself it is approx. 6.5 wide and 4.75 deep.

M42 ecu box dimensions.

could you get me dimensions of your ecu case? I just finished putting together the pin chart for the 318is ecu plug and it's a definite possibility to setup. Note I don't have a base line file for any m42 engines so you'd be on your own.

thats fine, there is a couple e30ers around here that have ms. Unforutnately i'm in europle until july 1st, but when i get home i can measure everything up for you if someone else doesn't beat me to it. How much do you think it would cost, same price?

Luke you still would need an I toothed main pulley, and sensor. But I could wire it so you could just plug the I sensor into the eta harness. No the eta ecu uses a different 2-row plug then the 3-row 325i plug. I haven't checked yet if the megasquirt would fit in a 325e ecu or not(I've got one laying around so I'll look).

Well, here is the deal. My buddy Ryan (E30Idea) wants to go MS. His goal is a turbo. I have a complete "i" harness (early) plus crank, trigger, whatever. I think it would be best if he went full "i" wiring, added an "i" head, intake, etc and turbo'd. He needs to go step at a time, so we might do "i" intake, TB, crank, sensor, injectors, etc...basically, an M20B27 motor in block and head only, then build a motor to slip under that.

Thanks for answering all of my dumbass question so quickly.

another interested if made for the m42.

$150 if you are wanting me to mount the board in the case etc... Ya I could dump the code into the board and your stock cluster should work fine.

[xLibelle]

how much if i just want you to make me the harness? I'll send you the case for you to gut and solder. Since youre doing it assembly line fashion, it would be best that you hook it up for me. I have all the rest.

asside from the hardware, can you provide the bits of code or entire flash ... i assume this will accomodate my stock cluster?

wow amazing ill be buying one shortly.

yeah im down,pm sent

This is very cool! Nice job!

[StereoInstaller1]

Hokay, 'nother question.

Maybe a couple...

If this were done to an ETA, would you need anything more than the crank position sensor? Would it be wise to add the entire "i" harness, or could you rock the ETA wiring?

Is the ETA ECU the same size/pin configuration?

Thanks, man.

Great job, BTW.

Hokay, I gots more questionz.

1. Can you lose the AFM? What woudl you want me to do instead, use speeed density or MAF or what?

2. Is a different TPS required? Wasn't it the E36 TPS that bolts in?

3. How far can you take this one? As in can you change the MAP sensor adn be turbo-ready? Can you control a wastegate with this?

4. Is it possible to add a knock sensor on this? I understand that an M20 is too noisy to use one, but what about an M50?

5. I cannot seem to find a picture of the LCD. Do you have one?

6. If I were to have a car-puter, would it be able to display tuning data (RPM, A/F R, timing, whaddevah) adn show it on a monitor? Can you make changes while driving?

Thanks!

1. Ya no AFM, or MAF needed. Megasquirt uses MAP pressure instead. All you need is an air intake sensor somewhere in the intake tract, either the oem bosch one or an GM sensor. So basically no restriction from the airfilter to the throttle body
2. Yes you have to have some sort of variable TPS, the e34 auto m20 one bolts right in and just needs wiring. Or the e36 one can be used and you can make an adapter bracket
3. You can go as far as you want(as long as it all fits inside the box). The board has a good size prototype area where you could set up boost control, fan control, vanos control etc...
4. Yes a knock sensor can be easily added( a knock controller is needed, I personally really like the viatrack unit)
5.
6. Ya you could set up a car-puter My friend has one in his car and can view all the engine functions real time and adjust any parameter. He mounted a 7 inch touchscreen panel down in the center consul.




As for the M50 again it depends on space, I have a non-vanos ecu sitting here and it's too small to fit the megasquirt board in and still conceal all the wiring. For some of the smaller ecu's I can make adapter harnesses to adapt the megasquirt db37 plug to the stock engine harness.
