| Innovate regarding temp issues with wide bands...... Taken from here:
[ http://www.innovatemotorsports.com/forums/archive/index.php/t-5256.html ] Customer of Innovate.... In the Innovate user guide, it mentions that if the oxygen sensor is exposed to temperatures above 500 deg C (900 Deg F) a 4” x 4” heat sink is required. A sensor timing error will result rendering the meter useless. PLX widebands DO NOT need a heat sink and will function all the way up to 850 Deg C (1550 Deg F). 850 Deg C is the recommended Bosch sensor maximum temperature operating range. PLX wideband will provide operating stability even in your most demanding applications where EGT is high. Owner of Innovate Wrong reading of the users guide. Bosch specs a max BUNG temp of 530 degC and a max EGT of 850 degC. The LM-1 and LC-1 monitor BOTH temps and error out if EITHER is exceeded. The max bung temp is more commonly exceeded in practice. A conventional wideband cannot monitor the bung temp. With the LC-1/LM-1 it is possible because of a peculiarity of the Bosch sensor that we exploit.
And to answer your question about temps.....I have seen many Z's with small turbo's running full boost with 2.5" exhaust with EGT at the turbo temps of 900c to 950c
Hotter than I would like to see, but thats what they make pushing the envelope.
800c is more common with 3 inch exhaust and larger turbos.
At any rate it is way over 900F with either set up.
installing the bung in the downpipe that is attached to something this hot is not what I would suggest (shrug)
