UG and ECM Volt Too High

2176 Views 4 Replies 2 Participants Last post by  Kalpazan
Every now and then when I start the engine and Ultra Gauge will prodice "ECM Voltage Too High" alert. Measured ECM voltage at that time is 14.90. A minute later and voltage drops to ~14.50. This looks pretty normal to me and I would raise the UG ECM voltage limit to say 15.00 but wanted to make sure first. So, any opinions and spiritual philosophies about that?

Thanx! I just checked UG manual and there min alarm for battery voltage is off (?) and max alarm is 14.9. I think I will turn off max alarm and set min one to say 13.80 (found that on Internet).
