It's a good product. There's a few parameters to monitor all at once. throttle position vs a/f vs rpm. Gets complicated trying to remember everything all at once. It just takes time and patience. Most important part in any big bore setup. Never tried the forcework yet.
you talking about the JB PRO? oh yah defiently it's a great product. many people had success with it.
the forceworks is just for people who dont want to deal with maps/laptop (forceworks has 3 maps imbedded, stock , +5%, +10%) then +/- 16 increments of adjustments. cheaper due to built in a/f meter. problem is im pretty sure it won't work well with race cams or more extreme setups since u can't tune the fuel maps with a laptop. maybe they will come out with one in the future? then that would rival the JB pro.
so right now those two units are on a different level.
so for now in taiwan all i see is forceworks for street (stock,mild,sport cams) and some race (depending on engine build). most race engines (race cams) still rely on full adjustable ecu like a JB pro.
