Message: [QUOTE="Charles, post: 1339544, member: 103"] The cold weather timing seems fine. The reason I had to mess with the multiplier so much for pw is because the full power pw is so low compared to stock, that there wasn't much to be multiplied. In cold weather, most all that extra pw is not injecting fuel.... it's holding the poppet valve open while molasas tries to squish past it. So it doesn't matter how fast the injector is, most of the effort is happening before any fuel ever comes out. Since the injectors needed 8 to 9ms in order to crank the engine, and I only have 2.12 at full power.... there needed to be a lot of multiplication. Compare that with the stock injectors that run over 4ms at full power. Multiply 4ms by a factor of 2 and you get 8. But multiply 2ms by a factor of 2 and you only get 4.... truck doesn't ever even see diesel fuel in cold weather at 4ms. Timing is not affected by this problem. The rotella is just as slow to flow into an injector with a 400 nozzle as one with a stock nozzle, so the factory timing trim is gtg. [/QUOTE]
