That can't be solved in programming, that problem is purely physical. We are limited in terms of valve orifice size and working pressure as well as the number of valves we can use per cylinder port (one, max). The only remaining way to do what you want to do would be either to use a spring assist, at which point the cylinder would actually slow you down, which isn't good, or you could use multiple small cylinders each fed off of its own solenoid valve.

we have a solenoid that worked last year and doesnt this year but in a weird way. when programmed as a double solenoid, the double solenoid does not work on any of the plug-ins. but programed as singles, only one side works. you switch the plug-ins of the two sides and the opposite side is the only one that works. is this a programming, wiring, or some other problem and any ideas on how to fix it? help would be appriciated
