Well I finally got around to buying a wideband, so I got the AEM UEGO.
Just have a few questions about install.
1.) Where exactly do I want the exhaust shop to weld the bung at?- I have included a photo of where I think it should go, am i right?
2.) Where would I run the sensor wire thru to get up the the A-piller?- Would I run it thru the firewall, or under the frame like the rear o2?
3.) Running the gauge in the a-piller, wheres a good place for power and ground?
4.) I have Evoscan to log with, How would I be able to log the wideband with Evoscan?- Would I splice into a ECU wire?
I have read threads and instructions, I just want to make sure I understand everything.
Thanks for answering my questions!
From AEM:"Mount the O2 sensor in the exhaust system at least 18 inches downstream from the exhaust port. If you anticipate high EGT's (over 800C), run a turbocharger, run at high RPM for extended periods of
time or plan on running leaded race fuel then you must mount the sensor at least 36 inches or more downstream of the exhaust port as all of these can cause the sensor to overheat. On turbocharged engines the UEGO sensor must be installed after the turbo charger, if not, the pressure differential will greatly effect the accuracy of the unit. For accurate readings, the sensor must be mounted before catalytic converters and/or auxiliary air pumps. To prevent collection of liquids between the sensor housing and sensor element during the cold start phase, the installation angle should be inclined at least 10° towards horizontal with the electrical connection upwards"
