Good point and well made. The document will come to good use if anything ever goes wrong with mine! (knocks on wood) I forgot everything to do with wiring my car as soon as the engine started. It was a coping mechanism! ![]() |

I've added a further page (Pg 19) to the document today and uploaded to the same location. I remember it was hard to get my head around how the A/C and Radiator fan relays worked on conjunction with each other so the extra page details the current flow through the relay coils and contacts in various A/C and coolant temperature configurations. btw, The orignal document is in A3 if anyone wants a larger size. |

About sealing the cables through the firewall, you could use rubber blanking grommet instead of normal grommets and then drill a small hole through the blanking grommet. The centre of the blanking grommet is thinner which will flex to match the cables. ![]() You need to smear a bit of rubber grease onto the cable to get them to fit though the small hole and to slide along to the right spot. Sorry about your back. I get the twinges quite a lot these days and can't do as much as I want to. I try to bring he work up to my level but it is awful hard to do with a complex job like yours. Hope you are better soon. |

Alan, I am very sorry to hear about your back and I sincerely wish you a very speedy recovery. Back isues are never fun - but I guess Diazapam will tak that edge off! Your display looks great and a real credit to you! How come its reading two different A/F's?? With regards to the firewall penetration for the shifter cables - did you not keep the factory disamond shaped item that seals the firewall?? Its the best thing to use I reckon and if you havent got one well worth a trip to the wreckers to get one. All the best mate, hang in there!! Cheers, Tricky |

Tricky - I do have the Starlet firewall cable grommet & metal pieces ... somewhere. I just need to find it ![]() As for the display, the figures are only hard coded test numbers at the moment - hence the two different A/F's between the two photos. No thermocouples etc are connected yet. If there is enough memory left on the microprocessor, I'll also be implementing a peak value display and possibly data logging. Over the last 4-5 years, I've made kits for (and sold multiple of) a sequential shift light, intercooler spray/pump controller, overboost alarm, and 4 channel temperature display, but this one is the best yet and discards the need for lots of gauges in the car. Being able to monitor all the vitals of the car without the cabin looking like a pilots' cockpit is nice and doesn't scream "break into me and steal all my sh!t" ![]() |

I like it Al - reminds me of the Digidash I have for The Cat - very simple display!! |

So the dash cluster will show you what ever you need, custom to what you want it too? So if you have the right sensors and what not you could read just about what ever you want? Coolant temp, oil temp, ambient outside air temp even? If so that's somethig I've often wanted, cos the digi dash you can get are a little limited to what they can read. I'd like to have different pages with what ever readings I wanted on them... Make sense? |

This display (small @ 75mm x 25mm) will simply be supplemental to the main instrument cluster as I will be retrofitting the factory Starlet cluster (tacho, speedo) in the Mini. The sensors used for this are all standard K-Type thermocouples and what temperatures you can read - oil, ambient air, intake air, coolant, turbo housing, EGT, transmission etc- are only dependant on where you can fit a thermocouple. This design is based on a simpler kit that shows just four temps that I used to sell (but it was removed from the product lineup late this year) and is improved further to include Air-Fuel Ratio and a boost pressure sensor to alarm on a lean-out conditions of a high A/F under boost. It looks like a simple display but there is thousands of lines of program code for this display and although I have had customers in the past ask for customisations to what the (original retail) kit can do, the hours involved in changing the program and in some cases redesigning parts of the circuit board is generally not cost effective. |

From memory the top mount is roughly 300 x 300 square, still a top mount though and any cooling is better than none... |
