Hi guys I just bought an Ultra Guage off Tomc612. I like it alot, im just seeing if anyone here has one. Im seting up my gauges to view, Hp and Tq are one i wanna view. My question is, when I set up hp its set at 200 and the gauge knows the car is 3.5 L. Do I leave it at 200 or manually adjust to 350? also it has engine % efficency at 24. Any one know what this means?
scott: got one on my chally. when i set it up i don't remember it being that smart. i think you have to put in all the values. i got all my screens divided into 1/4 & see a lot of values but not tech savy enough to know what some of them mean. i watch air input temp versus real air temp closely. load. pedal positon & a few more. main reason i got it besies a few of the gauges was for the performance end where it can track times although with it being winter & the chally being rear wheel drive not much chance to use till spring. but amazing it does work considering the price.
From the user manual (http://ultra-gauge.com/ultragauge/support/Ultra_Gauge_EM_Plus_3_4_14.pdf):
Horsepower 1 and Kilowatts 1 are derived from the vehicle's Engine Control module and based on a percentage of maximum Torque. This gauge must first be configured by setting the maximum torque for the target vehicle. The maximum torque is a common parameter that can be found by searching the internet for the engine specification for your vehicle. The torque is commonly specified as a Torque @ a particular RPM. For example, 200 ft.lbs @ 3200 RPM. The Maximum torque is set via the menu system: MENU -> Vehicle Setup.. -> More.. -> Set HP1 Max Torque
The torque may be entered in either fl.lbs or N.m
Horsepower 2 and Kilowatts 2 are derived based on the amount of energy being consumed by the engine and the engine's efficiency. By default the efficiency is assumed to be 24%. This means that only 24% of the energy contained in the fuel actually produces power or torque output. 24% is an good average for typical modern vehicles. This value can be adjusted if more specific information is available via the menu system:
MENU -> Vehicle Setup.. -> More.. -> Set HP2 Efficiency
So you should put in the HP/TQ for the tune you have. If stock, it's easy. If tuned, you need a dyno to get these numbers.
Efficiency: Probably is a number out there for GTDI vehicles. It will be an average, as the manual says, as efficiency of conversion of fuel to usable power is over a range of operation. Most people care only about mpg as a practical measure.
