Hi, just wondering if there is an ecu on this as I’m looking at buying a 1989 mk2 polo s. Been quoted insurance for a black box but I don’t understand how they would fit it if there is no ecu? 

Thanks for any help. 

they dont have an ecu ...not sure how the black boxes operate , might only need a ign live and earth ?

They normally plug in the on board diagnostics (OBD) port. A mk2 doesn’t have one of these, as it doesn't have an ECU. 

I thought some of them were GPS & GPRS (sim card) based so not needing any info from the ECU data ?

Cheers guys, found out they work off ignition.

Mk2f was the first to have EFI in 1990, quite rare for a small car.

 

I still get asked at mot times why does it have a lambda sensor
