Well, it's been a year since I last worked on or posted any progress on the Locost. Between settling back in to Wisconsin, trying to finish my Cobra replica and health issues, I have placed it on a back burner.
My Cobra is almost finished and will (hopefully) soon start the process of getting it inspected and licensed here.
As to the Locost, I had been chasing trying to obtain a Microsquirt for the EFI conversion. Since the pandemic, they have been in short supply. But I saw an ad for one -new, in the box in the Chicago area. A fellow (my age) was working on an old Porsche 911 and was installing a 3.6 with the intent of using the Microsquirt for the EFI. He realized it was not going to do what he needed.
So, I purchased it for the price of just the ECU, but included was the 30" cable, the USB converter cable and a 1 BAR sensor!

I think I will mount it on the firewall. It is the right length for the cable. Most of the functions that are available will not be used as I will follow the design that Moss Motors had for the MGB EFI conversion. The difference is, they used Borla throttle bodies, and I am using converted (gutted) SU carb bodies with a machined adapter replacing the dash pots to fit GM style low pressure injectors that squirt fuel into the throttle chamber. The program is already downloadable from the internet for this configuration. It does not require the ignition or crank speed sensor to be used, just MAP and spark timing since it is batch firing the injectors. This even eliminates the old manual choke during warmer days!

I am very pleased. Now, I have to wait a little time too tight to start back on the car until the weather improves enough that I can move the patio furniture back out of the workshop and reposition the car.
Stay tuned!
