I'm about 99.9% sure that the Honda 216 and diesel-powered cars that use the RF transmitter (starting from 94.5 MY, ie all cars who have BD as their last letters in the VIN) don't have any form of EKA. Their engine ECUs were not as "advanced" as MEMS and are not paired to the 5AS (you could actually replace those engine ECUs with one from any similar donor car with no need for reprogramming). A friend of mine with a 94.5 MY 216 SLi not long ago had his fob out of sync with the car, I told him how to sync it again by pressing down on the fob 4 times but in the interim when he only used the key, he never had to use any form of EKA to get the car started...the car has the 3-round plug with green cap in the engine bay.

In fact, the 94.5 MY diesel and Honda-engined cars, which again use the same RF fobs, have a specific immobilizer unit, one used in many other Rover cars, such as 600 and 800, its part number is YWC103630 and it looks like this. It's a Lucas 3TH unit. The K-Series engined 94.5 MY and beyond cars don't use it.
