Ok so with this problem I've been haivng with my Mi16 not sparking recently I've been looking for a guide to the ignition system.   The other day I was randomly searching for pictures of BX's and was trying to see if anyone had had a go at the styling of them, particularly curious to see what may have been done about the rear wheel half cover thing. I found a website dedicated to BX19 16V's and on it was a download for a program called CAPS. It's got literally everything you need to know about the 2 row ECU found in the BX and the Mi16   I don't know whether or not this program is known by people on here, but at the off chance it's not, I thought I'd post it up anyway.   Enjoy!   Edit - see attached file as link above is dead. caps.zip
