Hey Mark,
I know that they needed to be the correct part number CHT for each MY & engine in order to work properly - i.e.: -037 for the `73 2.0, -043 for the `74 2.0 (maybe 75 & 76 GC 2.0 too??), etc.? So will you be making them in the various "flavors" to match to the EFI systems in the different MYs & engines of the 914s, as did Bosch? (IMG:style_emoticons/default/beerchug.gif) Tom /////// |

Well I have the spec for the 012, so I can make it work. I'm not sure the variations on the others, is it size or resistance? Anyone know for sure?

They're physically the same, the only difference is the resistance/temperature curve. I think Brad Anders has some graphs on his website.

Mark,
MCMark had an alternative design he worked out for these. It is supposed to be a more modern construction alternative. You may want to contact him regarding it before you dive into production. Marty |

I think Brad Anders has some graphs on his website. --DD IIRC it is those + the reaction time is slower on the -037 with the factory in-line resistor, but the ECU, MPS, etc. are all set up to work together correctly, while mixing components generally leads to running problems. Probably Brad Mayeur or Brad Anders can explain the details better than I! (IMG:style_emoticons/default/beerchug.gif) Tom /////// |

I was mis-remembering the CHT sensor info. What I found on Brad Anders' site is the following:
Sensor Temp = 39 deg. F (ice bath with thermometer) Temp = 61 deg. F (room temperature) Temp = 210 deg F (boiling water at 1000 feet altitude) 0 280 130 003 6.10 K ohms 2.94 K ohms 199.3 ohms 0 280 130 012 NA 2.85 K ohms 191.2 ohms 0 280 130 017 3.63 K ohms 1.74 K ohms 124.7 ohms Not a chart, but a table. It comes from about 3/4 of the way down this page: http://members.rennlist.com/pbanders/DJetParts.htm The ECU page (http://members.rennlist.com/pbanders/ecu.htm) has charts showing voltage on one specific point inside the ECU versus CHT resistance. That may have been what I was remembering. --DD |

So are you probing (IMG:style_emoticons/default/sheeplove.gif) the community? (IMG:style_emoticons/default/poke.gif)
I'll probably need a spare for the white car's 1.7L (1.9L) |

Well looks like there is enough commonality that they may be interchangeable, but not identical based on this -
Available new. The ...012 sensor is in short supply. Either sensor should work OK. I'm looking at doing these again because I need them. Offering up the GB to those that are interested, but may raise the price to $75 after the GB if there's not much interest on these. I did ping McMark on the phone today, but will follow up if he has a better answer. I may have located suitable materials for the build but can't check til Monday. I don't have much of a choice as I do need one, so I will be working on a solution one way or another. Just really surprised that there's not much interest. |

I forwarded my info to Mark so he can proceed with this. (IMG:style_emoticons/default/thumb3d.gif)
If you're car doesn't run well until it warms up, you might have a CHT issue. Any stock FI car that's working correctly should run as well cold, as it does warm. |

SO,
As noted we will be making the Original Customs version of these. They will be 3-4 weeks out. I Like what Mark had going with these and we can make these available again. The key here is we need some quantity to get the price down, so hopefully there is enough demand to make these pencil out. Right now the only sources that "say" they have them are at least $80. The discussion I had with Mark was that most people don't realized these have failed as think as it's an old car it will run a little rough until it warms up. They just live with it. We will be doing a diagnostic video (once my car is back together to show you the effect of the failed one I have and the improvement. There is a good possibility that a few could benefit from having these and don't realize it. SO if you want in on the GB price you will need to bump the thread to get the code when ready. Given the costs these will be about $60 after the GB SO whos' in? |
