As I look down the list, I see some interesting possibilities. The engine load function could really help with economy. Find what load your engine is most efficient at, then set cruise at that speed. In hilly areas with little traffic, turn off cruise and monitor engine load. Some of the guys at ecomodder have come up with load based cruise control systems. I wouldn't use them in traffic, but they're a great idea in some circumstances.
I'm really looking forward to using the transmission slip function. I see my rpm stay steady while my speed rises, but have been told by one of the transmission sponsors that these transmissions sometimes do that up to 3000 rom or so. I certainly hope so, but I'd love to compare slippage rates at a given engine load with other members here.
Obviously, the vacuum/boost function will be a great thing to have.
It says it also measures inlet temps after the blower. Well, it says after the intercooler, but since I don't have one of those I'm assuming it measures after the blower. Looking forward to that.
Injector pulsewidth and duty cycle. I'm not sure what the difference is. I would assume pulsewidth tells how long the injector is open, while duty cycle tells the percentage of time it is open vs the designed limits for it to remain open. Not sure, but looking forward to learning about it and putting it to use.
I think the record function is going to be a huge help.
And let's not forget the toys. 0-60, 1/4 mile, and horsepower.
In short, what's taking Santa so long, anyhow? Shouldn't he have been here by now? Sleigh troubles? Maybe he should put an aeroforce on that thing.
