Sharpie Posted July 23, 2003 Share Posted July 23, 2003 Just got my car back from having a FMIC fitted and the internal Clock/Thermometer, which shows the external temperature seems to be well out, where previously it was spot on. I was driving back to Reading on the motorway at a steady speed (not fast, really) and the external temp went up to 38C, the weather reports for that day were a max of 29C. I suspect that the FMIC is blocking or warming up the air to where the temp sensor is located ?? Anyone know where this is so that I can try and move it into a free flowing, air flow ? Is this shown on the EPC ? I do not have a copy. Cheers Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted July 23, 2003 Share Posted July 23, 2003 Theres something with an H on it near the bonnet release, is that it? Quote Link to comment Share on other sites More sharing options...
Geezabloke Posted July 23, 2003 Share Posted July 23, 2003 Peter Where did you have it done? Which one did you go for? Have you noticed any improvment? Costs? Cheers for any info as im looking into getting one fitted shortly.... Dave Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted July 23, 2003 Share Posted July 23, 2003 There is, what looks like a temp. sensor just inside the large opening of the front bumper. It's on the drivers side at the top of the opening. You'd need to be on your knees to see it. Not sure if that is it, as the J-spec has it too. (J-spec's don't have the temperature display in the clock). Hope that helps... Quote Link to comment Share on other sites More sharing options...

That's the High pressure cap for the air con. Al. Temp sensor will definately be under the front bumper where it will be shielded from the outside air flow ,or it will pick up a windchill reading.It is probably near something that is hot or warm now,during the IC fitment.

Nathan Posted July 24, 2003 Share Posted July 24, 2003 Originally posted by Supra_Al Temp sensor will definately be under the front bumper where it will be shielded from the outside air flow ,or it will pick up a windchill reading Oooh...thats interesting. I thought inanimate objects didn't suffer from wind-chill. I thought wind-chill was the effect of quicker evaporation of water from the skin. I could be totally wrong though! Either way, yes, the temp sensor is clipped to the metal bash bar behind the front bumper. I think Matt is right about being just able to see if by getting on your knees. You might need to take the bumper off to get it back in though! Cheers Nathan. TDI PLC Quote Link to comment Share on other sites More sharing options...
Sharpie Posted July 24, 2003 Author Share Posted July 24, 2003 Thanks for the help so far........ Do you think it is this ? (The undertray has been re-attached btw ) Quote Link to comment Share on other sites More sharing options...
Nathan Posted July 24, 2003 Share Posted July 24, 2003 Peter, Yes, I think it is, although I can't actually see it in the pic. It should look like a little black plastic probe...? As long as it's location never sees direct sunlight I think that will be the one. Cheers Nathan TDI PLC Quote Link to comment Share on other sites More sharing options...
Sharpie Posted July 24, 2003 Author Share Posted July 24, 2003 OK - Thanks again all, I should get the car back today (Heater matrix replaced) and I will have a good look around to see if I can find it. I guess I could test it by using a hairdryer on it to confirm that this is the probe. I'll let you know how I get on. Quote Link to comment Share on other sites More sharing options...
400BHP Posted July 24, 2003 Share Posted July 24, 2003 when i get in tonight, i'll photocopy the page out of my workshop manual that shows the exact position and test readings if you want it?? Quote Link to comment Share on other sites More sharing options...

TDI PLC I thought wind chill was the temperature differential caused by cold or fast flowing air passing over something causing it to be chilled by that process...? I dont believe water evaporates quicker the colder it gets, which is in theory what you are saying, what you are describing is in fact... perspiration (sweating) Quote Link to comment Share on other sites More sharing options...

Cheers for any info as im looking into getting one fitted shortly.... Dave Dave, I do not have much to go on at the moment as I only had the car 3 days before it went into Toyota for a new Heater Matrix and Diff Oil cooler and have not got it back yet. I did not push the car becasue of these leaking items and so, can't tell really just yet. For the other stuff, I will post up my findings so that everyone can see when I have had some time with it. I have other items to report on too Quote Link to comment Share on other sites More sharing options...

Nathan Posted July 24, 2003 Share Posted July 24, 2003 Originally posted by 400BHP I thought wind chill was the temperature differential caused by cold or fast flowing air passing over something causing it to be chilled by that process...? Agreed. But I thought that only something that actually had heat contained within it could lose it faster via windchill. Perspiration is indeed exactly what I meant My point was that say a fan blowing air on you in the summer will feel colder because it is evaporating your sweat faster. Thus, you can feel windchill on say your face because the airspeed is helping to remove your heat faster. A similar thing happens even if you're not visually sweating. Something made out of plastic, metal or anything inanimate doesn't have any any heat to lose so it will always be what the ambient is. Airspeed doesn't have much effect (unless you start going REALLY fast...and heating things up) I guess what I'm trying to say is that the surface temperature of a plastic ball held out of a car window whilst stationary will have the same surface temperature at 100, 200 or even 400mph. What do you think?! Sorry for the thread divert! Cheers Nathan TDI PLC Quote Link to comment Share on other sites More sharing options...
400BHP Posted July 24, 2003 Share Posted July 24, 2003 I would say, that you are correct, something moving through the air will not loose any latent heat if it does not have any energy contained in the form of heat within it, however its ambient temperature (say room temperature) will be reduced if it was held in air flow? The point at which the air flow speed will affect the temperature of the said object is a very valid point for discussion i feel! I would think that the temperature is read by the air immediately surrounding the probe and warming the probe to the same. If the air is passing fast over the probe will this not affect a temperature differential?? God knows! Hijack complete!! Quote Link to comment Share on other sites More sharing options...
400BHP Posted July 24, 2003 Share Posted July 24, 2003 Right, having consulted the manual and gone completely through the electrical chapter I can confirm that the temperature gauge for outside temp does not exist...wooo hooo! good old toyota!

Sharpie Posted July 26, 2003 Author Share Posted July 26, 2003 Dave, I had the HKS R-type fitted by CW. He did a great job a usual. Things to consider when fitting a FMIC on UK Spec - It blocks the rad a lot but, I did not have any issues at all for the 2 days I had it, the amb temp on the M6 home was around 25-29 deg C that day and the car was fine but, did not drive at WOT. The FMIC does obstruct airflow or heat up the airflow to the AC cooler and so, the normal very cold AC was kind of cool ish, somthing I was not aware of before I purchased it so, if you really need a cold AC system then IMO a FMIC is not for you. The temp probe is affected as per this thread but, I was going to find it and relocate it. You loose the active spoiler and the front part of the undertray which, is incorporated into the active spoiler but, there is a mod you can do to fix this http://www.mohdparts.com/mohd_bottom_panel/install/index.html not sure if this can be done on the R-type though. The Auto box cooler which is located in the front passenger side air scoop on the F- bumper has to be removed to allow fitting of the FMIC, not sure of the issues, if any, this causes, I understand this is not on the j-spec. That's about it, I can not say anything about the performance of it as I did not have it long and did not test it. HTH m8 Quote Link to comment Share on other sites More sharing options...
imi Posted May 7, 2011 Share Posted May 7, 2011 Trying to get the Clock Temp to work on a Jspec TT. Got a UK Clock with the UK clock plug. Located the Temp Sensor (behind the front bumper grill) - Question is - how do I wire it up? Running separate wires to the sensor doesn't result in a reading. Anyone have a circuit diagram or some tips as to what I need to do to get it to work. thanks Quote Link to comment Share on other sites More sharing options...
