How to: reading Early EJ series ECU error codes

[Joel]

Here's just a quick video I made a few weeks ago demonstrating how to read the ECU error codes on early EJ series engines

The advice you receive on here is worth the paper it's written on.
Your experiences are worth shed loads to others, including the f'ups - live and learn.
Wouldn't YOU rather learn by someone else's mistakes? So would they.

'78 Bay, 2 litre 091 box, EJ20 NA & the ashtray's on the 'right' side.
I don't lean forward for hills any more
Bugger, missed out on "Live fast, die young"

Very nice.

Loved the part with the error code sheet.... Appears in your hand outta no where
