All kit PCBs come pre-programmed and verified. No firmware upload required right after soldering. Actually your microRusEFI would
communicate via USB if you solder just USB connector or feed USB via 48 pin connector.

Re: tight connector area and traces on PnP boards and talk of smaller drill size:
Random JLC support quote, interesting stuff: "for the size of 1.1mm in the original file, they will become 1.25mm after making compensation, then the spacing between holes to lines will be only 0.108mm, our limit is 0.2mm" I assume 1.1 becoming 1.25mm is drill sizes.

I've been playing around with my MRE for about a week now off and on, just on the bench.

Have to say I really like the RusEFI environment, this board is just cool, small and versatile.

Ive been adding a few wires to the main connector to eventually hook it up to a simulator to fiddle with some knobs.

One issue i had, and this is completely on me, I seem to have used the wrong connector. I had a couple of that 48 pin connector lying around from other cases i bought ( plastic ones from alli-express ) . The crimp connectors and plug are not all the same. The crimp connectors that came with the MRE case I ordered are
square, and the crimp connectors that fit the connector I soldered on are round.

Not sure if anyone else has run across this issue but sure had me banging my head for awhile.

An exercise in panelization is currently taking place, mostly for fun really.

PSA: Fully assembled microRusEFI price will go up next Friday or after next four units sold, whatever happens first. There is also a good chance that kits would now longer be offered or maybe similar price bump. https://www.ebay.com/itm/333532119947

microRusEFI was a major success and I've learned a lot with it. Next phase would be to adjust with all the knowledge we've gained with MRE and Proteus.

Quick question,
Is there a way to add a second VR input? We've got a WRL/Champcar miata and possibly wanted to bring in the Speedo (switched to NB style VR)

You would have to buy a VR board on eBay if you really need two VR.

I believe you do not need any VR. NA and NB miata both use Hall signals, please note that my primary test mule is NB and somehow it runs on microRusEFI as is, in hall configuration.

To the best of my knowledge, the VSS signal fed into the ECU on NB Miatas is a TTL-level square wave generated by the speedometer electronics. You don't need VR for that.
