The new update to version 1.85

Our latest update offers many benefits to G3 customers.

Please take time to download and update, you’ll be glad you did.

NOTE: For GPS interface you must have software Version UPDATE 185 in G3

DISPLAY FLICKER

The first thing you will notice is the display is flicker free under all conditions. We changed display manufacturers to improve viewing angle and other display specs but it caused this problem. It has taken enormous effort to remedy, but now it’s done.

LEAN BOXES

We have suppressed the lean boxes below 2000 RPM so you won’t encounter them during run up. Some users found this confusing or inconvenient. Now you won’t see them until you need them. 

KNOB SENSITIVITY

The knob sensitivity problem has been solved. You will notice a vast improvement in both knobs. You will also notice we add another feature to further aid control in turbulence. When you reverse direction the instrument will require two clicks instead of one. We have found this to be a very effective feature.

HORSEPOWER

The horsepower display has been improved and requires explanation. First the HP display depends on three configuration parameters and these need to be set correctly.

The (1) Max RPM, (2) Engine HP and (3) turbo configuration are set to match your engine.

(1) Typically max RPM is 2700.

(2) For turbo’d engines we have a new configuration identifier - a digit followed by “B”. You may choose 0, 1, 2, 1B, 2B. The B means boosted.  When absent it implies turbo-normalized. If your engine manifold pressure can exceed 30 inches then choose boosted.

(3) The HP calculator has takeoff and cruise modes. Any RPM within 125 of max is considered takeoff. Anything below that is cruise mode. As we have said before this is theoretical HP not real HP. It will not identify engine faults. Without a torque sensor on the engine there is no such thing as a real HP reading.

If the Engine HP parameter is set incorrectly it will distort the percentage HP calculations.

The HP algorithms do the best they can to predict engine power even though some essential information is missing. The display now shows power in either yellow or white. When the incoming information is favorable and will yield a good result it will display the value in white.

So what are the favorable conditions?

The instrument needs fuel flow, RPM, peak EGT and all the configuration data set correctly. If it doesn’t have peak EGT because you haven’t leaned yet, like during take off and climb, then it assumes you are leaning correctly on the way up. Once you reach a good peak EGT the HP calculations will work well. Peak in this case means you have all the lean boxes displayed above the columns. Once you reach this point, leaning past peak or going back to the rich side of peak will still produce good HP indications. The value will display in white. If you operate outside of normal parameters the HP will be less accurate even though the display may still be white. When you change manifold pressure the fuel air ratio will be approximately the same but to the extent that is not the HP accuracy will compromised. The HP calculations work best during leaned for cruise operation, where they are most useful.

GPS FUEL FLOW

The G3 will now send fuel flow information to your Garmin GPS.

If your GPS is configured to use the Shadin Fuel Z format it will display fuel flow rate.

NOTE: For GPS interface you must have software Version UPDATE: 185 in G3
