12:05 Garage- ’70 Duster build
I know I've been a little quiet lately. Lots of other things going on besides car stuff. Some may remember I killed an O2 sensor shortly after getting the hemi running. I replaced it and it worked fine for a very short time and that sensor failed. I didn't quite understand why since I had thousands of miles of trouble free service out of the same gauge and sensor. The only thing that changed was the bung. I replaced it when I redid the exhaust for the hemi. It turns out the bung I purchased was too short which was putting the sensor too deep into the pipe and I was cooking them. It was a 1/2" long bung. Some research showed me that Innovate Motorsports supplies a 1" bung with their kit. A quick call to them to confirmed my thinking. I had been wanting to upgrade to the dual sensor gauge so this was the right time to do it. Sticking with the same brand also allowed me to reuse the bezel that I painted.
The sensor doesn't even protrude out of the 1" bung. Both sensors are now installed. I still need to go drive it to see how even they are. Installing this did require some additional wiring. The second sensor has its own controller and it sends the data to the gauge via CAN bus. That controller needed power and ground. The second sensor also has 2 analog outputs. I don't have any spare analog inputs on my ECU, otherwise I'd split the fuel tables and have 02 correction for each bank individually. Maybe one day I'll get an I/O extender.
I am interested to see if there are any major differences bank to bank.
