MSD 7765 Wide Band Sensor

What O2 sensor comes in the kit is it a Bosch. I need a extension cable the cable from the module is too short to reach my left O2.

Another way to do this is to move the CAN-Bus base unit closer to the exhaust so that the O2 sensor reaches. Use these 2’ , 4’, 6’ CAN-Bus extensions MSD 7782, 7784, 7786

It’s also possible (not exactly sure) that this cable can also be used between the 7765 and the 7740 CAN-Bus.

I’ve already mounted can-bus hub and both modules on my right door x.

I was wondering about this too since I just ordered one for my dragster. Ignition box way up front and obviously O2’s way out back...

How long are the leads for those? I’m pulling off my LM2 and going to the MSD ones. For my dragster.

the O2 sensor that most use (lm1, lm2, Daytona) is the Bosch LSU 4.2 sensor, msd states that theirs is the LSU 4.9

if your going to add a extension I would use a 4.9 cable. their are measurements on this site to determine which sensor you have.

Daytona Sensors made me two custom length extensions for my Wego. If I remember correctly one was 91" and the other was 105. Both of them to the door cost me 35 bucks total. May be worth a phone call.

Is the Red wire from the O2 Sensor Module connected to a “Continuous” +12v battery source?

only comes on when the ignition switch it on

Turning ignition switch ON to Grid turns the modules on attached to the CAN-bus hub for communication..

Select 7765 in Grid and go to the Gauge 1 tab. Select the Battery Voltage and Heater Voltage channels. What do they indicate?

Battery voltage is 12.6 off and car running was 13.8 I o2 read 6.4 and but it wouldn't change like it didn't read. As soon as you select the o2 setting the heater open fault would pop on. Clear it and come right back on.

What does the “Heater Voltage “ channel display for voltage ?

Prior to starting, unplug the Oxygen Sensor from the O2 sensor Module and look at the pins (qty 6 ) in the plug ends to see if they all look the same for position. If good, then re-seat plugs and try viewing the Heater Voltage. No work, call MSD. They’ll ask you some of the same questions.
