Edit: I have a ms2 v3.0 going to run ms extra
So i understand where to jump the u2 chip and remove R21,C20,C21,R22,R23,Y1,C24,C25 from the clock circuit.

Where I am confuse is that it says that pin 4 and 5 can now be used for injector 3 and 4 but then it tells me where the 4 injector channels are at.

Do i need to run my injector wires to these 4 channels? or can i just run from the normal injector bank 1 and 2, and pin 4 and pin 5.

Is there any additional hardware that need to be installed?

and yes i did look for answers lol non were present.

Which megasquirt? Which board rev?

I was planning to use the Jbperf board for full sequential.

4-Channel Ignition/Injection Driver Board

Sequential Injection Code for MS2

Good board, ran my low-z injectors off the peak and hold board.

You do have that board, right? Right? Because if I'm understanding you correctly - no, you can not run your injectors directly off the megasquirt board by doing that mod without having the injector driver board.

dannymo

ahh this is what i needed to know. I will have to order up the board. it looks like you can run spark off of these too.

Thank you tons!

I so don't miss hacking up a v3.0 board to run the simplest of functions.

dannymo

lol i am assuming you are running ms3. Kinda wished i just had saved up the little extra money and got the ms3 but ooohhh well. lesson learned

it's all just so hacky.

dannymo

ya it is but im almost done making it then i get to put it in my car which im sure is another set of problems will arrive

I understand it's hacky but is there anything about (Jbperf board for sequential) it that makes it less effective vs MS3? Serious question.

dannymo

lol i don't really know this is my first ms. It seems like you can do a lot of things with the ms2 just easier with the ms3

less effective, no. Modding a v3.0 ms2 board is just a PITA.


The circuit for injectors is pretty darn easy, if you have a clear proto area you could easily add all four drivers in there.

this picture shows how I add two extra drivers on a DIYPNP:



You'd have to build all four on a v3.0 Ms2.

That's one of the funnier things I've heard in the last month.
