Running sequnetial injection & ignition through my MS3X
MUHAHAHA.
fuel injector harness modded from batch to 4 separate inputs, with the ability to go back to batch if I ever need to plug in an inferior MS to my car. Onto my COP harness... |
You dirty dog. I think I will order my daughter card just because of your thread. Thanks buddy for the motivation.
|
I'm doing it cause I just picked up the MS3X expansion card. I didn't want to have to build additional drivers for everything, so for hardware it's pretty much just plug and play. As far as wiring, I need to run 4 additional wires to my engine bay (2 for each) and modify my MS batch harness...
|
MS3X...you double dirty dog. I'm so jealous.
|
Good god man quit dragging your heels!
|
I'm working on the MS3X wiring harness now. Going to stop for dinner soon, then I'll run wires tomorrow into the engine bay and try it out...
|
all done with the external stuff finally...good lord that took all day. I completely redid the COP harness so that took a big chunk.
|
Very nice, whats some of the benefits of the MS3 board over MS2?
|
Here's the fuel injector harness:
http://www.boostedmiata.com/gallery2...3x+052_001.JPG added two inputs so all four channels have an individual input, then added a connector so I can go back to batch if necessary. reworked COP harness: http://www.boostedmiata.com/gallery2...2/ms3x+057.JPG same thing, all four cops are on four different inputs, connector that can bring them back to wasted. I did an awful job building it the first time after tearing it apart, I replaced the connectors I build with factory pigtails.

Unsuccessful first attempt. I'm unsure if I have a wiring issue or setting issue. I'm sure I have sequence correct and the injectors wired the correct firing order. I'll have to test one at a time later, it's 97*F out and feels like 105*F so I'm done for the day, I'll mess around tomorrow in my parking garage.
EDIT: Went back over the documentation and I did in fact wire the coils up wrong. I have cylinders 1-2-3-4 as A-B-C-D where it needs to be A-C-D-B. I think that should solve the issue. |
Firing order fail...
Otherwise looks awesome and kudos for attempting. In for driving impressions. |
Set both ignition and injector outputs in firing order. 1 3 4 2. That should fix you up.
Are you bringing cam in on JS10 or through the 3X? |
that always screws me up.

Say hello to Frankensquirt.
|
I understand the sequential ignition part....but whats the benefit of doing fuel sequential as well?
|
There are more benefits to sequential fuel than ignition. You can run larger injectors and maintain a steady lean idle is the big win, mild improvement in town driving mpg and smoothness too.

This, crank trigger, VVT.
I like this a lot, there is a lot of good stuffs going on with MS dev at the moment. |

No, Ben I did not run the cam signal in through the MS3X, I left everything else but fuel/spark as is. Is there a benefit, I'm running a dual opto circuit

. Infact I have precisely zero AE atm in the hunt for an irritating half misfire, and throttle response is virtually identical, I've half a mind to leave it off completely... |
