Pal in the US wanted a modern engine ECU (MegaSquirt) built into the case of the original. It's a NAS spec Rover. Californian MOT includes a visual inspection for non standard parts. As well as an emissions check.
I've done just this on a couple for the UK - where an owner wanted it to still look standard.
Offered to send him instructions on how to do it, as it's not that complicated. But he wanted me to do it for him, and what's more send me all the bits needed. Which I could have sourced here, obviously. The original ECU having the same outer case as UK cars.
He had to search to find a reasonable cost carrier from US to UK. Package weight 3.80 lb. UPS wanted nearly £200.
It has arrived in the UK by FedEx. I've had a letter demanding 36.40 gbp for custom etc costs. VAT, etc.
Since it will be sent back, are these charges justified?
BTW, it really does show how nice it was to be in the EU. Done one for a chap in Germany. No extra charges involved, and easy cheap carriage.
