Need a little clarification on full sequential injection
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?
|
oh shoot sorry
i have a ms2/v3.0 going to run ms extra |
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. |
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.
|
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.
|
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.
|
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

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: https://www.miataturbo.net/attachmen...ine=1415193494 You'd have to build all four on a v3.0 Ms2. |
