Message: [QUOTE="Charles, post: 1338906, member: 103"] Okay..... got some REAL good cold weather testing. On top of Beech Mountain at 5,506' right now. Yesterday, temp was 19 with 32mph wind, do NOT underestimate the power of wind! With my tables set up at 4ms of pulsewidth and 2500psi for cranking the truck would sputter along but not lite off. I had to crank the pw multiplier at that temp so that my final output pw was 6.5 before the truck would spin and WACK... crank right up with a ball of black out the pipe. Fast-forward to this morning. Same elevation, but temp was .5 and winds were 32mph. At 6.5ms of pulsewidth the truck would not even sputter.... nothing out the pipe! I had to max the pw multiplier at 3.05 IIRC, and then toss in another 1 at and below 650rpm for a total multiplier of over 4, and a total pw of over 8.5ms before the truck hit and fired off with another roll of black. This is with the truck not plugged in, just sitting out in the yard getting bombed on the top of the mountain. And I mean TOP..... about 100 feet away is the sheer cliff off the back to the little town in the valley below. Reason for all the pw multiplier is that my max pw value in the file is 2.12 for full power with a 200 nozzle on a PMR. So for cold weather cranking, you waste a massive amount of pw just letting the oil get in and actually fire the injector. In contrast, at the same cranking icp for a stock AEB file, the pw is over 3.5ms. So the stock multiplier gets you plenty of fuel. I had to crank them up because multiplying 2.12 is hard to get up to 9 or so ms. [/QUOTE]
