Re: 929 cam pulse
When I sit on the bike, left is for left or #1 cylinder is who starts at what side for TDC. So when I set my 1-4 to the " l " mark next to the T, I want my #1 cam lobes to be pointed out. So both narrow ends of the cam lobes point out to the exhaust and intake ports. That's where your timing should be cam to crank position #1 TDC.
Notice I stand on the right side to line up the crank to TDC, and I continue to be on the right side of the bike, I point my #4 lobes outward is no, wrong cam position is that you assembled the cam sensor 180° out of phase. Get it? No spark then... is caught you on a perfect catch22. The bike only assembles one way.
Can RAM be Flashed or erased? That's a yes and no kind of watch how I believe how it works something like this:
RAM = Is volatile, meaning, erases when the key is turned off. What was saved goes to ground. The tach/speedo needles swing when key is on. This too erases anything in the way is to zero out itself to... The bike starts at 0. In ECU speak or in the binary process of the language is 0000 in machine speak. Your last move was to turn the bike off at idle. The crank is dead-key off = 0000 or no idle number saved is a dead engine is not matching crank speed. Why save an idle number for start? No way... Sort of make sense?
Flash: = This is a saved binary number to calc off of. The pc would be an example of how you would change the air to fuel ratio. This is a flashed map from base zero or say the ECU is set to ROM and you'd look at that being saved, no can flash. So instead of flashing the ECU to set the fuel trim, you reset the fuel by flashing the output signal from the ECU that was set to ROM @ 14.7 AFR. You however flashed a map to 13.1 AFR.
Can RAM be flashed is yes. Think of the radio in the car. You sort of flash your stations to the buttons.
Can flash be erased is yes. The flashed RAM is about to meet ground. Once the battery is removed, the radio reverts back to ROM or that flash you cannot touch or reflash sort of no you cannot flash the radio to your stations and battery off keeps them? Radio wise, no. This is the yes and no of it = Catch22 style.
How many can decipher this out is the processor only works one way and I'm stepping to the music.
a. So if my interpreters are out there, we are looking for 180° out of phase = No start.
b.We are looking for the swapped ECU that made no change is that sounds like both are good?
c. We are looking elsewhere like the processor needs 5v and if 12v or more at the battery is not there, bike only works one way is 12v into the ECU and 5v out is where is the battery if we are cranking with charger or just kept on cranking and never put a charger on it yet sort of got me by the testicles??
d. We did not swap ex cams with the cam sensor positioned degrees off is to look to see if the cam to crank sensors line up equally?
