Can you have 2 wideband sensors to monitor both banks on the Ultimate DL Playback Tachometer

Asked by: HEH#
Thank you for contacting us. Unfortunately this would not work. We would advise you to use one of our full data acquisition models if you want to do this.

Does the 5" DL tachometers come with the pinion magnet ring, driveshaft sensor, cable to the driveshaft, and the bracket to hold the drive shaft sensor.

Asked by: cobalt #2061
We do not include a bracket for the drive shaft sensor. This is something you would need to fabricate/provide. We also do not include a Drive Shaft Collar with magnets. We offer a few size options on the collar. You can see each of those sizes under the respective model numbers; ST269389, ST269387, and ST269388.

Does the driveshaft have to have 4 magnets? Are the number of poles adjustable?

Asked by: Krusty
Hi Krusty, Our Ultimate DL tachometers use 4 drive shaft magnets. This is not adjustable. Thanks, Jim

I just purchased this tach. Why doesn't the usb cable come with a nut so I can mount it in a bracket or dash?

Asked by: Tony A
Hello Tony, thank you for your question. The nut was not previously available with the tach, however, we do offer send it with our tachs now. If you got your tach before the nut was available or ordered a tach that came without a nut, contact our tech support team here: They will be able to help you with your situation.
