Chipset Posted January 11, 2011 Report Share Posted January 11, 2011 As mensioned in the help file - manual of the ecu the are 2 prefered Bosch IAT sensors wich are : 'The recommended sensor for turbocharged is a Bosch 0 280 130 085. On naturally aspirated engines this sensor may be substituted for a 0 280 130 039, which is cheaper and easier to fit.' But when you are going to setup an analog iput as a IAT sensor there are only the following choices -Std Bosch NTC -Bosch 0 280 130 017 -Hella 6PT 009 109 041 -Delphi AC -KTY83 -Cal Table 1 -Cal Table 2 -Cal table 3 - And 2 more for Yamaha FX/FZ My question is which of the previous recalibrated profiles are the right one for those 2 prefered bosch sensors, cause from what i can see in the specs datasheet those two have different characteristics ( Different temprature VS resistance ) so there must be 2 diff profile .. But i cant see none. Here is the screenshot for the details of those two (From the official Bosch datasheet) http://img213.imageshack.us/img213/9554/tempsensor.jpg I also attached the official datasheet for better reading Thanks in advance sensors_temperature.pdf Quote Link to comment Share on other sites More sharing options...
Chipset Posted January 12, 2011 Author Report Share Posted January 12, 2011 Someone must know about this ? Do we have to use the first profile for both of them even thought they are different? Im confused Quote Link to comment Share on other sites More sharing options...
Cameron Moore Posted January 13, 2011 Report Share Posted January 13, 2011 Hi Chipset, It's along time since we tested those sensors but our notes suggest they had the same calibration (despite the picture, we may have to revisit this). It seems the Standard Bosch cal should cover the '026, '039, '085, '070, '097 Bosch sensors. With the Std Bosch you should see 2.5kOhms at 20degC, the other Bosch sensor (017) will be 1.65kOhm at 20degC. Hope that helps -Cameron Quote Link to comment Share on other sites More sharing options...
Chipset Posted January 15, 2011 Author Report Share Posted January 15, 2011 Thank you for your answer . Maybe you or anyone else that have the tool and time can measure this cause from what bosch says those are different ;/ Quote Link to comment Share on other sites More sharing options...
Chipset Posted January 25, 2011 Author Report Share Posted January 25, 2011 I wonder if you have any progress on this ? Its crispy clear that those two have different ressistance VS temp curves and we need the right calibration to get the max from the open type sensor Bosch 0 280 130 085 Thank you in advance Quote Link to comment Share on other sites More sharing options...
Cameron Moore Posted January 25, 2011 Report Share Posted January 25, 2011 Hi Chipset, This is on my 'todo' list and should hopefully get around to sorting this out in the next couple of weeks. Will let you know when I've got an answer. -Cameron Quote Link to comment Share on other sites More sharing options...
Chipset Posted May 15, 2011 Author Report Share Posted May 15, 2011 Cameron ? any progress on this one =) Quote Link to comment Share on other sites More sharing options...
Cameron Moore Posted May 17, 2011 Report Share Posted May 17, 2011 Hey Chipset, I did look into this (and was then interrupted by a silly earthquake). The answer is yes they are different, but only 1degC out from each other so too close to justify a dedicated calibration. I verified this with testing as well. The different curves aren't actually that different if you adjust the scales to match (I did this photoshop style to confirm). Hope that helps -Cameron Quote Link to comment Share on other sites More sharing options...
Chipset Posted May 19, 2011 Author Report Share Posted May 19, 2011 OH ok Thank you Cameron Quote Link to comment Share on other sites More sharing options...
