The following notes cover my exploration of retrofitting fuel injection onto a previously carburetted
Land Rover Series III fitted with a 3.5 litre V8. I used the Lucas 14CUX 'Hot Wire' fuel injection system
and have been very pleased with the result. In the links below I've included the original Lucas workshop
manual along with schematics for two dash mounted fuel injection monitor systems (FIMS) along with my
complete project notes for the fabrication and installation. Note that these cover the in tank fuel pump
fabrication. The MK III FIMS is built around a 2.4" LCD touch screen and microcontroller in a small box
a little bigger than a mobile phone mounted on the dash. It is designed to read and display live telemetry
(including fault codes) from the 14CUX ECU via the serial diagnostics port. Additionally it displays raw
analogue voltages from both lambda sensors as bar graphs. In fact, being able to see the state of both
lambda sensors is I would argue the most important diagnostic tool required for a healthy 14CUX system.
The firmware took me about 4 weeks to write and so far has passed through three different types of
microcontrollers, and five different versions of the hardware.

Scientists and Engineers have been waiting for a successor to the magnificent Hewlett Packard HP 42S calculator for years.
In the interim, a bunch of smart chaps got together and repurposed a different HP calculator to create the interesting WP34S or WP 34S
reverse polish notation calculator based on the HP 30b (financial) calculator.
Version 3 of the original WP 34S manual written by Paul and Walter is available below - but if you struggle reading that manual (like I did)
then by all means have a look at my beginners guide. Originally this started out as a personal study aid as I explored the WP 34S and grew from
hand written notes into a more formal user guide as I delved deeper into the machine. Its an open source device, so it does feel right and proper
that community ideals should be respected and so I decided to make the guide available freely across the web.
It is very much a work in progress and is being extended as and when time permits. Not all sections are completed, and some haven't yet been
drafted (for example there is no matrix section) so do keep an eye on my site - and feel free to share links. The document does contain a draft
number on the footer of every page, and a summary change history table tucked in at the start to make clear what version changes have been made.
The guide is useful for me, I'm hopeful that you may find the same thing.
