Talking about that technic, I aproach this thread to ask about it two things:
1.- Why people do it?, I mean... the only knowledge I've about it is that racers do it to not damage the engine while downshifting, because when you go to a gear under the one you're driving, the motor gets an impulse to rev up and if you do this technic you're like giving a bit of help to state the revs at the good point before depress the clutch. Am I right?
2.- If I'm right on the point from before, on video games it will be like a question of fun? because it's not a question about of life-cycle of your engine like on real life... and I don't see the point of better or worse times if you do or don't the Heel/Toe thing... because if you don't do it, the motor will rev it like always to get the right rpms for the downshift.. and yeah it won't be smoth but it works like always.
The heal/toe technique is to match engine and transmission speeds when downshifting. While I guess it could be to help with preventing engine/transmission wear or damage, it is mostly to prevent abrupt engine braking that could upset the balance of the car while braking and downshifting at the same time. Smooth = fast.
As to why do it in the game, since the GT series is more of a simulation, the more realism you can add, the better. I don't have the G25, therefor no clutch so I don't 'have' to heal/toe. If I did have a clutch, I would probably try it if I was having problems with a car getting squirrelly under braking/downshifting. In real life I have never 'had' to do it, but I did do in my old GTI (R.I.P.) and I wasn't very good at it. It take a lot of practice.
Put in 6-Speed mode and when you gain control press Triangle. Top button on shifter.
Also is this method correct. Say i'm going 5th to 3rd.
I press brake, Press clutch, select gear, rev, release clutch, re press clutch, select gear, rev, release clutch.
Thanks again
If you are going from 5th to 3rd and don't want/need any engine braking you can just skip 4th, actually you could just skip the heal/toe. In racing though it would be like this:
brake, clutch, neutral, clutch out, rev, clutch, 4th, clutch out, clutch, neutral, clutch out, rev, clutch, 3rd, clutch out.
Like I said before it takes a lot of practice.
