Anyone got any suggestions for the acceleration pump settings with the pcv?
Thanks for the infoAny time on lift an engine will go lean. Nature of the beast. Even fuel injection suffers this issue.
The accel pump feature is to combat this. It uses the throttle input to determine if you 'snap' it open and it adds whatever fuel you input for a certain amount of revolutions of the crank on that 'snap'. You determine the amount of sensitivity it uses to determine if you are crackin it open or just cruising. In theory, the sudden rush of air on lift will be offset by added fuel. So this feature is not just for cams or turbo setups. If you understand what it is for, you can set it yourself. It will be a lot more accurate if you monitor your AFR while setting it, but you can play with it. The max amount of revolutions you can set it for is 90 revs of the crank. Very small. It actually does help out with them throttle snaps when you are coming out of a corner, or showing off for friends. Gives ya that lil edge. Takes the slump out of jackin the throttle and takin off like a rocket ship.
Play with it. You'll find where it is fun. I set mine a wee bit rich, cause not like the bike needs it, but the poof of black smoke when I crack it open for the homies sure is funny.
So far I haven't had any problems, bike is running way better than stock, if it keeps running how I want it and the plugs don't get fouled up I'll keep the afr by gear and the acc pump enabled, almost no fuel gets added at idle just enough so it runs sounds smooth.I didn't read that book you wrote, but carbs did it to have an idle circuit. Many race carbs didn't have one because it was wide open most of the time and didn't need to idle. Now if you needed an idle, you bought a carb with accel pumps.
With EFI on these bikes, stock bolt ons, I see absolutely no reason to implement that setting.
AFR by gear, accel pump enabling, etc. is just a way to screw everything up. It will never run right and you will foul plugs like crazy. Nothing worse than dumping fuel at idle and part throttle to an EFI bike that has that already programmed in.
