Mode 3 is a step type adjustment, not proportional to the Program knob as I think you are implying. Program knob only sets the direction. Read instructions carefully. I would suggest resetting both Mode 3 and 1 to factory defaults first. See instructions on how to do the resets. Then do Mode 3, then 2 (if needed), then do Mode 1 or 9 whichever seems easiest to you. The both do the same thing (adjust map table entries) but do it in different ways. Most builders find Mode 9 easier.

I tried to address this issue with Mode 6, the adjustable MP threshold= for the lower map table range.=A0 The idea is to have the lowest in-flight= MP select the 0 - 31 range and ground condition select the upper range (32= - 64). =A0 Being successful at this also requires the rpm threshold of the= low range be chosen correctly and everyone's seems different so it may= not be right for your installation since it is not programmable.=A0=A0 Con= trollable pitch props also complicate this issue, even on carbureted engine= s.=A0=A0 It's the same situation that causes P51's to fart, pop and= belch fire during this phase of flight.=A0=A0 Everybody thinks that's = cool tho....

I've never had the problem myself since I always plan my descents to av= oid windmilling the engine at low throttle (that's not good for the RD-= 1x drive).=A0=A0 It's also a waste of the potential energy in altitude.=

But, if the EGT's are the only problem during this condition, I'd i= gnore it because you can't damage anything in the engine at this low po= wer setting.

Published February 10, 2011

| Associated Press
A new drilling technique is opening up vast fields of = previously out-of-reach oil in the western United States, helping reverse a= two-decade decline in domestic production of crude.
Companies are inves= ting billions of dollars to get at oil deposits scattered across North = Dakota, Colorado, Texas and California. By 2015, oil executives and analyst= s say, the new fields could yield as much as 2 million barrels of oil a day= -- more than the entire Gulf of Mexico produces now.
This new drilling is expected to raise U.S. production= by at least 20 percent over the next five years. And within 10 years, it c= ould help reduce oil imports by more= than half, advancing a goal that has long eluded policymakers.
"That's a significant contribution to energy = security," says Ed Morse, head of commodities research at Credit Suiss= e.
Oil engineers are applying what critics say is an envi= ronmentally questionable method developed in recent years to tap natural ga= s trapped in underground shale. They drill down and horizontally into the r= ock, then pump water, sand and chemi= cals into the hole to crack the shale and allow gas to flow up.
Because oil molecules are sticky and larger than gas m= olecules, engineers thought the process wouldn't work to squeeze oil ou= t fast enough to make it economical. But drillers learned how to increase t= he number of cracks in the rock and use different chemicals to free up oil = at low cost. "We've completely transformed the natural gas industr= y, and I wouldn't be surprised if we transform the oil business in the next few years too," says Aubre= y McClendon, chief executive of Chesapeake Energy, which is using the techn= ique.
Petroleum engineers first used the method in 2007 to u= nlock oil from a 25,000-square-mile formation under North Dakota and Montan= a known as the Bakken. Production there rose 50 percent in just the past ye= ar, to 458,000 barrels a day, according to Bentek Energy, an energy analysi= s firm.
It was first thought that the Bakken was unique. Then = drillers tapped oil in a shale formation under South Texas called the Eagle= Ford. Drilling permits in the region grew 11-fold last year.=
Now newer fields are showing promise, including the Ni= obrara, which stretches under Wyoming, Colorado, Nebraska and Kansas; the L= eonard, in New Mexico and Texas; and the Monterey, in California.
"It's only been fleshed out over the last 12 = months just how consequential this can be," says Mark Papa, chief exec= utive of EOG Resources, the company that first used horizontal drilling to = tap shale oil. "And there will be several additional plays that will c= ome about in the next 12 to 18 months. We're not done yet."=
Environmentalists fear that fluids or wastewater from = the process, called hydraulic fracturing, could pollute drinking water supp= lies. The Environmental Protection Agency is now studying its safety in shale drilling. The agency studied use = of the process in shallower drilling operations in 2004 and found that it w= as safe.
In the Bakken formation, production is rising so fast = there is no space in pipelines to bring the oil to market. Instead, it is b= eing transported to refineries by rail and truck. Drilling companies have h= ad to erect camps to house workers.
Unemployment in North Dakota has fallen to the lowest = level in the nation, 3.8 percent -- less than half the national rate of 9 p= ercent. The influx of mostly male workers to the region has left local men = lamenting a lack of women. Convenience stores are struggling to keep shelve= s stocked with food.
The Bakken and the Eagle Ford are each expected to ult= imately produce 4 billion barrels of oil. That would make them the fifth- a= nd sixth-biggest oil fields ever discovered in the United States. The top f= our are Prudhoe Bay in Alaska, Spraberry Trend in West Texas, the East Texa= s Oilfield and the Kuparuk Field in Alaska.
The fields are attracting billions of dollars of inves= tment from foreign oil giants like Royal Dutch Shell, BP and Norway's S= tatoil, and also from the smaller U.S. drillers who developed the new techn= iques like Chesapeake, EOG Resources and Occidental Petroleum.
Last month China's state-owned oil company CNOOC a= greed to pay Chesapeake $570 million for a one-third stake in a drilling pr= oject in the Niobrara. This followed a $1 billion deal in October between t= he two companies on a project in the Eagle Ford.
With oil prices high and natural-gas prices low, profi= t margins from producing oil from shale are much higher than for gas. Also,= drilling for shale oil is not dependent on high oil prices. Papa says this= oil is cheaper to tap than the oil in the deep waters of the Gulf of Mexic= o or in Canada's oil sands.
The country's shale oil resources aren't nearl= y as big as the country's shale gas resources. Drillers have unlocked d= ecades' worth of natural gas, an abundance of supply that may keep pric= es low for years. U.S. shale oil on the other hand will only supply one to = two percent of world consumption by 2015, not nearly enough to affect price= s.
Still, a surge in production last year from the Bakken= helped U.S. oil production grow for the second year in a row, after 23 yea= rs of decline. This during a year when drilling in the Gulf of Mexico, the = nation's biggest oil-producing region, was halted after the BP oil spil= l.
U.S. oil production climbed steadily through most of t= he last century and reached a peak of 9.6 million barrels per day in 1970. = The decline since was slowed by new production in Alaska in the 1980s and i= n the Gulf of Mexico more recently. But by 2008, production had fallen to 5= million barrels per day.
Within five years, analysts and executives predict, th= e newly unlocked fields are expected to produce 1 million to 2 million barr= els of oil per day, enough to boost U.S. production 20 percent to 40 percen= t. The U.S. Energy Information Administration estimates production will gro= w a more modest 500,000 barrels per day.
By 2020, oil imports could be slashed by as much as 60= percent, according to Credit Suisse's Morse, who is counting on Gulf o= il production to rise and on U.S. gasoline demand to fall.
At today's oil prices of roughly $90 per barrel, s= lashing imports that much would save the U.S. $175 billion a year. Last yea= r, when oil averaged $78 per barrel, the U.S. sent $260 billion overseas fo= r crude, accounting for nearly half the country's $500 billion trade de= ficit.
"We have redefined how to look for oil and gas,&q= uot; says Rehan Rashid, an analyst at FBR Capital Markets. "The implic= ations are major for the nation."
