Here's three sites to keep you going

http://www.diagnostic-assistance.co.uk/mech_inj.htm (http://www.diagnostic-assistance.co.uk/mech_inj.htm)

http://www.users.bigpond.com/INTERJECT/ksitepln.htm (http://www.users.bigpond.com/INTERJECT/ksitepln.htm)

This last one has some good diagnostic info.

When you get through those and need more search out the Volvo, Porsche, VW sites, all used K-Jet.

I purchased the book on it some years ago in Perth but can't find it these days.
If it turns up I will PDF it.

The M-100 site has the K-jet diagnostics available but accessible only to members.

It is a very bloated PDF file chopped up into several sections to make it downloadable.

I was amused by the simplicity of this demonstration.  It really is a simple system.  The more the air mass sensor opens, the more petrol floods in.

Its all the other stuff (not seen in this video) like idle controls, warm up regulators, cold start valve etc. that complicate the simple system that K-jet is.

It's a beautiful system that just needs clean fuel and almost no adjustment except idle mixture and replacement of injectors when they start leaking.

I prefer "masterly inactivity" as the preferred method of maintenace with the exception of fuel filters.
