Triumph ITB 2.7 MS2 EDIS setup/install Q&A

Nditiz1 · 08-09-2021, 02:43 PM

I picked up this engine about a year ago and am finally going to finish it in order to make an event in September. This will be going into a 74 914.

Engine - 2.7 from a 76
Twin plug heads
X-Factory ITB Triumph setup
EDIS
MS2

Here is my setup:

nice setup!

I have a couple tips i wish i had listened to when i was putting my setup together.

1. grab a granite countertop remnant an make sure both sides of your intake manifolds are good and flat. I am still chasing minor vacuum leaks and keep coming back to the manifolds.
2. you might want to check your power brakes setup for leaks. I notice my AFR goes lean when i press the brake pedal. I'm pulling vacuum from cyl #2 from that large hose barb. Causes idle to raise when at a stoplight and i get some pops out the tail pipe too which is a little embarrassing.

Thanks for the tips!

Also, thanks for the air cleaner manifold plates that I bought from you (at least I think I did) last year.

Regarding number 2 I will be blocking the vac port on the side of the intake manifold that would be for the brake booster as the 914 does not have power assist.

Nick,
greetings and good luck with the project. i haven't seen one of the Speed Triple setups in a while.
I am putting together some docs for you that will provide the basics for install and tuning...along with the associated M'squirt manuals, etc...Some light reading for you. The manifolds and, likely the linkage you have were manufactured by Clay at Closed Course Motorsports. His website is down, but I may have the docs he supplied for setting up the linkage. Also, good advice on the manifolds......I reviewed the manifolds from the 1st run and they were nice and flat....but i've heard that later runs were not, so pampadori's advice regarding checking for flatness is a good one....vacuum leaks are not your friend and a beeyatch to debug. Also, i've heard that setting up the linkage can be fussy...but Clay did provide good instructions and, I think i have a copy...anyway...I'll email you some stuff tonight.

regards,
al

Thanks a lot Al. The specific wiring diagram you sent over is already starting to unlock the mystery. As you mentioned I do have Clay's linkage.

Nditiz1 · 08-14-2021, 05:23 AM

Getting a little further along.

I think I have the wiring all figured out, just need to start. I think I may make a bar to sit on top of the fan shroud to hold the vacuum bar. Has anyone mounted the fuel regulator on the shroud somewhere, looking for ideas.

al lkosmal · 08-14-2021, 06:37 AM

I've installed the vacuum manifolds on threaded standoffs, threaded onto the breather mounting studs......

I would mount the fuel pressure regulator to the firewall.....if possible

PS: I know this pic is of a 911, but the mounting locations will likely work for a 914....

They make adjustable FPRs that screw into the fuel rails. It’s a nice little in-line solution.

Radium Engineering is one example.

@TeeJayHoward - Thanks! that does look like a clean solution. Ugh $150, but it does make things more tidy. Al what do you think about the one posted?

I have not used those, but I'm not a fan of hanging that weight off of the end of the fuel rail/fitting, due to the engine vibration. My preference is to solidly mount the FPR to the firewall.......

I use a Tomei adj fpr that attaches to the end of the fuel rail. It's been perfect since installing 4 years or so ago. Has stayed precisely at 42psi where I originally set it.
Small and lite weight too.

Any issues with running this type of mount plate? Is there EDIS/Coil Pack interference issues having them this close?

jpnovak · 08-15-2021, 07:28 PM

No problems running that close.

BTW, Twin plug or redundant coils?

If twin plug pick one of the EDIS controllers as the "master". Send the VR sensor to BOTH controllers. This master will then send the PIP signal (from pin3) to the ECU. the ECU will return the SAW (Spark angle) signal to BOTH controllers.

Jamie,
That is being done. i've supplied the wiring diagram for this install.

Hopefully 4 standoffs over the oil breather can support this load. Shout out to Al for answering my pepper of questions. Also, fun with wires. More to come. Hope to have its first test stand startup in 7 days.

Nditiz1 · 08-23-2021, 02:52 AM

Currently where I am at:

Wiring about 95% complete
Need to mate spare case to block
Install starter
Check if fuel pump is bad
Either use 914-6 oil tank OR purchase a 30mm to AN12 adapter for 911 one

HUGE update-

MS2 is RMA - I don't know, the injectors would not fire even in test mode. Al was awesome and sent me out a microsquirt to use. It came in on Thursday night and I quickly went to work redoing the wires. Got it all hooked up and the NOID light came on in test! Success! But now no RPM's registered. So I went from RPM's registering in MS2 and no injectors to Injectors and no RPM's in the microsquirt. Back and fourth with Al all day Friday and finally found that an additonal opt wire needed to be wired into ground. After that RPM's registered in TunerStudio. Today I battled some fuel issues. I wasn't getting any fuel pressure. A quick ask to Al instructed me that the regulator was not setup properly (PO). The side ports are fuel in, bottom is regulation. Boom! set it to 40psi.

Here is the first startup. She's running rough, but I don't have the ITBs synced yet and I was running off the battery, forgot to hook the alt back up while diagnosing issues.

Nick,
I'm glad that the Microsquirt did the trick...this is a great example of how someone with good DIY skills can install, wire-up and fire-up one of these EFI/ITB kits.......including keeping their head screwed on straight, while debugging the system. Nick and I communicated on a regular basis, to review his progress, setbacks, including replacing a faulty ECU...and eventual success in firing up his engine. Nothing is better than that sound of the engine firing up for the 1st time. I've done it many times now, but it is still one of the coolest things you can do....congrats Nick and good work! Sounds great and let the tuning begin!

regards,
al
