throttle follower fuel vs tps AE

Can someone explain the "trigger" of TF fuel. It seems they(TF vs tpsae) resemble one another.

I would presume the TF fueling is miniscle so as to not trigger a change in BLM yet compensate for the increase in MAP occurring with a movement of TPS.

I would think an adjustment in TF fuel would be desireable if one has a larger TBI unit ?

This will be the first thing I change this upcoming tuning season to improve throttle response.

Re: throttle follower fuel vs tps AE

As the IAC is stepped open fuel is added. This can be from stall saver, TF, or idle control. The amount of fuel is the PW value for IAC fuel added. This PW value is compensated for RPM & temperature then added to the sync PW for injection.

Each 1 or 2 steps of IAC opening this fuel is added.
