Hi Eric,
I drove right through VT. We spent 3 days on the coast in Maine and then drove up I-89 and camped at Little River State Park in Waterbury. Beautiful spot for sure! We then continued on 89 to Burlington and took the Champlian Islands route (highway 2) up towards the border and crossed into Quebec via a very short jaunt back through NY (one right turn and done).
I can definitely see why Vermont got its french name from the Green Mountains. Gorgeous lush scenery.
Now, onto your questions.
The EFI system is based on the Microsquirt platform. That's the ECU. There is no AFM. Load sensing is by a MAP sensor which takes a vacuum reading from the intake plenum. There is also a TPS and intake air temp sensor. For timing, it uses a crank trigger ring and sensor on the back of the pulley (the kit includes a modified 3 groove pulley). The factory 2.1 idle control valve is retained. It is coil-on-plug and has an ignition amplifier. The harness is pre-assembled and plug and play. You literally can't screw up the install (well, at least not easily). You don't even need to set timing. It's all done ahead of time by Marco in the software.
Not sure what you mean about upgrades/fixes with a computer upgrade.
You cannot connect a Scan gauge (or I don't believe you can).
The software used to tune is TunerStudio. The paid version has an Autotune feature, however Marco ships the ECU with his own tune that I'm sure has been battle tested over the years. After I installed it, I connected the laptop and setup a log file for a 1 hour drive. I sent it to him, he checked it over and made a few minor tweaks based on my specific setup and sent it back to me. Been running with that tune ever since and on my entire trip and it worked out great. I don't see the need to mess with the tune ever again unless I modify something major on the engine.
The website has some info, but the best info is on The Samba and there are also a couple of good YouTube videos. Marco is also very responsive via Facebook Messenger if you want to pick his brain further. I've probably bugged him more than I should have, but he's always been very helpful. All of his products (I've now bought most of them) are well put together and high quality.
Hope this helps.
Andrew
