We have a one year old 970 with about 125 hrs. We understand that this year's models will have 400 hp. We asked the dealer if they could "chip" ours up to the new level. They said no, only new models will have this. Has anyone else heard anything similar?

The lexions actually all have a power bulge and they bump the power up all the time.

480 got boosted from 365 to around 400 plus a power bulge.

580 got boosted from 400 to 425ish

470-570's have had power increases over the years also.

Unless you mean that the lexions have plenty of power to throw grain over the rotors then you may be correct in some conditions.

There is still talk that a future dealer software package for one of the CCM units (supposed to be sometime this summer maybe) will change the max HP curve so that max rated power is avaible at 2000 rpm instead of 1800 rpm on both Cursor engines. This will not be a engine controller software change. Which means in reality that the engine controller had a 3rd fuel map set installed originally but was not active. The engine controller runs on its basic program normally. When the unloader is engaged the one CCM unit sends a signal to the engine unit that activates another part of the engine software to give it the unload boost. So for the CCM to signal a HP curve change and still have an unload boost that means they had this software on the engine controller all the time. Thats enough to p__ me off.

BTW a power bulge is basically a safety margin where when you push the machine past its programmed max torque(power) rating the controller actually allows a further increase in fuel metering so as not to stall the engine, up to a certain point.

Muddy,

We have a Lexion '580 +' which runs out of hp all the time, as do the Lexion 600's in UK conditions. HP is still the limit for them.


If you're running out of power on those two machines, then you have got to be nearly airbourne compared to other brands of combines.

Quote:They can hook their laptop up in the cab and increase the horsepower. They turn the unload powerbulge on full time. This takes the HP to 425 on the 970's (or 420, not sure) and 450 on the 9070's.

The 9070 can be programed from the monitor, 400 plus boost of 25 for unloading, or 450 continuous. 07- 8010 same. It's hard to load a combine steady at engine power limit to get a good reading but the 400 setting uses about 87 liters per hour, 450 about 92. So you get 112.5% power for 105.7% of fuel, all the parasitic losses handled by initial 87 liters. Same reason it says 16% power level sitting idling. By the way these readings were taken well above normal engine load but I was in research mode.
Hope you find this as interesting as I did.
I wouldn't have swagged those results.
