They are tiny pots that adjust the trim. They are like a repackaged, Two Bro racing maybe their on their website you can read up. Search "Dobeck" for the one I use.
Basically they are 4 tiny pots that you adjust with a pocket screwdriver.
Tfi = Adds fuel only. Has a second pot to close the low to mid so that pot does not layer over the mid to high pot fuel and double spray like over it in the mid to high. Only pot remaining is the accel pot.
Power Commander = Has ability to add and subtract fuel trim at rpm ranges. The Tfi is like a faucet with hot and cold handles. Cold will blend with hot say< Or there would be no way to let the hot water flow on it's own. Power commander can flood the low to mid rpm range. Then look at the mid to high and cut fuel on that side to run lean.
See how they [half 2] cut in signals in have you got that? Pg. 3-44 Note: Method splits in 2 feed the generic fuel injection signal.
Think: Idle circuit - (choke) - low to mid - mid to WOT and those are 5 circuits that are in the system.
Tfi ~ bleeds into idle.
PC ~ Can be left out or not (+/-) my idle.
Tfi ~ Needs no map or lap
PC ~ Makes map and needs a laptop to make/install map
Tfi ~ Can be shut down bye closing pots when wired direct to 12v and ground
PC ` Is cutting fuel as soon as you send the key to 12v, the unit cannot be turned off if wired direct.
Note: One website charges for maps and has the dyno to change all sorts of pipe/air cleaners to no cleaners and open pipe is a lot of models and a lot of money for something you can learn on your own. One map is $75 and there is a small window that you can work in. So, trim is trim is time to plus the minus or pot to foul out and stall it. Say you back it up a twist or a minus the plus I know jack about the Pee See; I told you I am no expert is clueless is if you expect me to pay for how to shit in a toilet is I think I will pooper my scooper is deal with my own shitandcabootle is doodle it up your trip pull ah map is members only too, you have to pay the premium. So you have to pay to be a member too is closing on you?
