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.

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?

Braineack

Here's the fuel injector harness:



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:



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.


MS3X Card:









Then to reward myself:

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.

I understand the sequential ignition part....but whats the benefit of doing fuel sequential as well?

richyvrlimited

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.

yep, ran seq. fuel only this morning. Was able to reduce the pulse width at idle a good amount, with a/c on from 2.4ms to 2.0ms. Throttle response was improved which was surprising because my EAE is already tuned very well. I'll get the spark firing order solved at lunch.

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?

At least I know my jumper connectors work to bring my harnesses back to batch/wasted. So that's cool.

This, crank trigger, VVT.

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

If you've already built out a second conditioning circuit, then probably not for this application. I would expect the conditioning circuit in the Expander to be a bit better than a simple jumper and pull up to JS10.

You know I'd forgotten about that, with sequential I've noticed you need barely any AE (can't get my head around EAE).

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...
