Yeah, they swapped from 46 (not 45
![Laughing :lol:](./images/smilies/laugh.gif)
) to 60 litre tanks in 1991, with the introduction of the Phase 2 facelift model. Not exactly model year 1991, they started with the Phase 2 model from identification number 567600 onwards. So if you put an okder info centre computer in, it will calculate the range and fuel economy wrong. Or it might even be set for a different ECU (there are settings for B18E, B18F, B18FT and B18EP/FP/B20F) which will, when configured wrong, show no data at all. But the fuel gauge and temperatures will always show correctly, though pre-1991 computers show temperature in Fahrenheit instead of Celsius if the switch in the info centre switch is set to miles.
You could try and fix the board by yourself if you have good soldering skills and proper electronics soldering tools (i.e. 20-30W soldering iron and 60/40 solder with rosin core flux). I can fix it for you, most of the cost is postage, though there is pretty much guarantee it will work afterwards. But if you need a volt meter and a rev counter without the light shining through, I've just got a load of spares from Trevor and I'm happy to pass it on to a good home!
(Trevor, I've cleared the backlog so yours is now in front of the line
