Did you ever finish this project???

ramius665

Not sure if AZbanks ever finished (or got started?) on his project but mine is still progressing. It's been a long, long road to get to this point. Building the engine was generally pretty simple, the biggest difficulty was getting the Speed Force Racing intake to play nice with everything else. It's not a bad piece but I don't know if it justifies the cost.

I've been working on the wiring harness off and on for over a year. It's required a mountain of research, planning and organization. I'm about 60% finished with the harness, the vast majority of the wiring is complete with the exception of the grounds. I opted to split the grounds from the COPS into two separate grounds for ease of construction, plus an additional chassis ground for everything else in the harness. Those all run to the ground on the bellhousing. The signal ground is still it's own ground on the block. I had an issue with grounding on my 944S which was cured by running a supplemental ground wire from the cylinder head to chassis, so I'll be mirroring this as well to help keep a good signal.

Truth be told, it's actually far faster, cheaper and easier to go with a pre-fabricated wiring harness than build your own. I've probably purchased $500 in tools and easily $350 in wiring materials. I haven't purchased heat shrink yet because I'm still on the fence about buying $250-$300 worth of DR-25 or $125-$175 worth of V-25. I know it's a huge upcharge for pretty markings because they're both built to the same MILSPEC but I'll be damned if it doesn't look the business when you see it laid over an engine.

So to all of you VEMS fans out there, while I think the ECU itself is a bit long in the tooth Peep does provide a true plug and play solution that removes literally hundreds of hours of research, planning and fabrication. That alone is worth the cost of purchase. But I'm happy with my route.

I don't know what you mean by long in the tooth, I don't know the history of VEMS before I bought it, lol...
but it's still a whole lot newer than L-jet Motronic

Love mine...

With Microsquirt, you get a 8ft flying lead harness. All the wires are labelled and color coded, and pre-terminated on the ECU side. It's somewhere between fabricating a harness from scratch, and plug-and-play. Took me a few days to finish the harness but it's definitely worth it - you only need a handful of sensors to run the engine compared to all the wires actually included in the harness.

Thanks for kind words.
ECU itself has been that way for several years because hardware was very advanced when it was designed and software has caught up in last 4-5 years.
Works with very advanced modern engines also (BMW S65/S85/S54) engines also with quad-VANOS, electronic throttles and idle valves over CAN bus) so it still has some punch

Just a short update and for future info for searches, the VAG TFSI coils fit perfectly on the 16V heads. They're about an inch longer than the VAG 1.8T coils and it's the right length to get them up and out of the head. The seals on the coils aren't ideal for our cars but you can repurpose the seals off of a set of ignition wires to seal them up well. Or you can leave the VAG seals there, they do keep the coils from moving around just don't environmentally seal the spark plug holes.

I received the last of my harness materials this week so I'll be finishing the harness soon. None of it is rocket surgery but it does require attention to detail and prior planning.

off of what engine?

ramius665

Any of the FSI/TSI 2.0T motors. The specific ones I bought were: Volkswagen 07K-905-715-F on Amazon for ~$25/ea. The "F" designation doesn't appear to have any of the quality control issues like the 1.8T coils did.

It was actually harder to source proper connectors for the coils than it was to find the coils themselves.

V2Rocket

what model years were those made?
VW has been making 1.8/2.0 T for hundreds of years now and the revisions/updates/replacements are indistinguishable to non-VW folks like me

NGK part number is U5015, been using those for ages on my 2.5 16v turbo.

I sourced the proper connectors about a year ago. Just wasn't easy to find the connectors by themselves.

But they fit well!

FYI
I pick up a ms3x this summer and installed it into my Supercharged 944s2. After figuring out a few bugs, the worst being an issue with the crank VR signal, she ran like a top. Smooth idle and pulled like a raped ape at 6500.... That setup was sold with a supercharger kit to a gentleman in north Carolina, who is putting it on his track car. I included an adapter cable that plugs directly into the Bosch motronic, to make everything an easy plug and play. I'm going to install a microsquirt into me car this weekend, and give that a shot too. Obviously, I have this figured out now, and would recommend it. If anyone has any questions, feel free to give me a shout
