    Is it possible for some of the Aliens to post short replays of some quick laps? Especially with apps on showing the pedal positions.

    I watched a lap onboard with @Cherno last night around the ring driving a RUF rt12 and wow :thumbsup: No way I would be able to get around even 1 corners at that speed.

    Would love to be able to see the throttle and brake position just to learn and see where I and other drivers in the drift-server need to improve. As the discussions with David around braking technique shown there are some interest in these.

    Thanks for the shout out Mael, that was a hairy lap!
    ill try to load something up but my internet has dropped down to a third of its normal speed so uploading could be a nightmare.
    can i upload the replay file from AC or do I need to make a youtube vid?

    The thing i really want to see is how you managed to go so quickly! During the last season I heard people discussing on TS having an app showing the pedal positions and was hoping someone knows how to include it in the replays :)

    As to which way is the best to post replays, no idea!

    NOT an alien but lets see if I cant help out a little.
    Here's this afternoons best lap -Bands Indy in the Escort- managed 6th on on rsr :)

    https://drive.google.com/folderview?id=0B9mHWBn2h_4GeTNhQmlXU2RwZTg&usp=sharing

    Link has replay file (goes in documents\Assetto Corsa\replay) then access from AC
    and the setup used (put pt_autosave_00_54_356.ini file in documents\Assetto Corsa\setups\ks_ford_escort_mk1) load as normal

    And the first piece of advice, you've all heard before but it really is the starting point...
    SLOW IN, FAST OUT!!! (proof - you cant know your braking point until you can hit 'max speed' on the straight)
    You WILL lose down more down each straight than can possibly be gained in braking areas by not getting this right.
    Approach this literally and cruise in to corner at 'low' speed and find the absolute earliest point you can get back on the throttle (not full throttle, just enough to shift the weight back and start getting power down, then find the point for full throttle). Watch the replay and note the 2nd, 3rd and last turns at brands show this quite well, brake early, back on the throttle to hold the rear down and maintain/gain speed, to much throttle and the rear will start to slide (wheel spin is fine so long as its forward, not sideways).

    I HIGHLY recommend using ptracker for its ACCURATE delta timing, taking a quick look at this mid way down each straight its easy to see whether your last exit was bad,average,improved.

    Extra Point... AC does a really good job (IMO) with 'weight transfer', the escort seems prone to looking up the front end with my brake balance setting, BUT
    applying the brake 'gently' so the weight shifts on to the front wheels gives better grip, allowing more brake (its a fine balance tho :D).

    Cheers

    Hi Mael,
    I put up vids a while back for a couple of the hot lap challenges with pedal inputs indicators in the replays.
    I used a combined F1 style app in the Nordshliefe vid, and just the Kunos pedal app in the Sierra.
    The wheel inputs are 1:1 with what you see in the cockpit view as well.

    A tip I guess I could give is always think of EVERY corner as a triangle... Going around a corner like a sweeper (circle) is not always the fastest way around it. Usually to get faster is you brake LATER (means less time braking, and slowing speed), and roll less, rolling may be quicker than braking at first, however you are still dropping speed while rolling, if you brake later you can still be accelerating for that split second or two and you will gain a extra tenth or two... If you average that over a lap it could work up to over a second quicker, it is better to be on the brakes as late as you can.

    You WILL have a slower mid corner speed, however you will also be on the accelerate earlier.... Keep that in mind... Also in saying this everyone's driving style is different. For me I try and be as smooth as I can, A. It's kinder on the tyre's and B. Smooth is fast. My style I always am braking INTO the corner most of the time (to the apex of the corner) while I am still turning in... Regulating the brake, and on the accelerate as soon as i can... I am either braking or accelerating (even it is only slightly of both)

    I am not the fastest, and this type of driving style may not suit you... However it will help somewhat.

    Also just another tip on keeping your speed and still being close to racing the guy in front of you, I always, ALWAYS lift off before my braking zone... So yes I roll behind you and I adjust my braking to your braking and maybe later if I have a different braking point than you (which most of the time I do) I hope it helps somewhat.

    Good one, will have to test it for this upcoming season as I'm often running into the back of people whom I'm racing.

    HIGHLY recommend this:

    http://www.assettocorsa.net/forum/index.php?threads/tire-psi-helper-thingamajig.31864/

    Some who drove in the last season (5... Escorts :)) would have heard my advice to run the pressures at 45psi.
    I would have never 'guessed' the optimum pressures were that high, I just got it via word of mouth, and it took 'a lot' of time off my laps.
    Just ran my 'test combo' (cobra@barbagallo) with correct pressures as the only setup change. Good pressures seemed to give about 0.5s per lap (65s) over the default setup and I beat my best time ever by 0.2s.
    Even beat one of Ben Cornett's times on RSR :D (too be fair... I ran 60 laps thats just on rsr, he ran one timed lap :eek::alien:)

    Thanks QC I will try. Definitely tyre pressure can make a big difference. I generally tune by temperature, and feel (by laptime) which takes quite a while to hone in on desired pressure. Having an app to tell you straight off the batt is great!

    Do you know if this app returns different optimal pressure depending on suspension setup e.g. camber?
    I assume the TAR figure returned is hot pressure so may be different to what put in at the pits (cold)

    Thanks for this mate, getting the correct pressures have been doing my head in.

    NOTE: app has been updated (1.1)

    AFAIK, optimum pressure in AC is only a single value, the tyre definitions can be found in 'assettocorsa/sdk/dev/v1.5_tyres_ac'.
    TAR, was the 'target psi'. The app has been updated and is a little cleaner. Well worth reading the OP and instructions.

    Some quick points:
    It wont select the type of tyre automatically, use the spinner (+/-) to change s/m/h etc.... (Will only show available types)
    F.Ideal/R.Ideal are the optimum pressures. clicking the small gray box on the center-left will change the dynamic values (coloured) through options of:
    Current P.S.I -> (real time value)
    Setup+- -> (shows what you should 'add' in garage)
    Ideal% -> (shows actual vs optimum in %value)
    Ideal+- -> (shows how 'far' you are from optimum)

    ill add onto what other people have been saying
    if you want to improve braking performance and consistency, buy a Load cell or hydraulic brake upgrade.
    In a real car, you judge brakes via pressure not distance.

    thats why stock g25 brake pedals with pots suck for this.

    also just practice and practice. its normal ill be on AC for about 1hour everyday. (more so for these league races, you guys are fkn fast lol)

    also watch youtube videos of pro race drivers if its a track you dont know (i do this)

    i run the pedal app purely to see if my pedals are not acting up. i had issues with my wiring that made the brake stick at 5% without pressing it, also my accelerator would only go to 95% on full press. thank AC developers that they added the pedal range option to tune this out lol.

    +1 had similar issues and did the same.
    I've stiffened up my brake pedal by stuffing the spring centre full of rubber. It breaks down after a while and is probably due for a change out but gives the pedal a more familiar feel.

    This must have been the best advice I've received. In the last few races I have been able to stay close and have decent battles with drivers for a number of laps all without crashing into the car in front of me. Thanks R0TOR!

    I stumbled across the manual for the original Grand Prix Legends by Papyrus. Has some good stuff in there! :thumbsup:

    1) Don’t go too fast. At most of the corners on all the circuits, you will need to begin
    slowing even before you can clearly see the corner.
    2) Learn the circuits. There is no shortcut here. Before it is possible to go very fast
    at a circuit, one must first know which way to turn, when braking is necessary, and
    where to place the car on the track. There is no substitute for a lot of laps at a track.
    You will pick up a lot of visual cues that help you find your way around-the groove is
    helpful in showing you the right line.
    3) The throttle and brake are steering controls. In a road car, on the street, you steer
    with the steering wheel and control speed with the throttle and brake. All this changes
    once the tires start approaching the limit of adhesion. At that point, the steering wheel
    is no longer the primary steering control. Instead, the weight of the car on the front and
    rear wheels will more directly control the car’s rotation. Applying the brake will put
    more weight on the front, which will make the car want to turn more, up to a point.
    Conversely, applying the throttle will put more weight on the rear, which will make the
    car want to straighten up, again up to a point. An added complication: too much
    throttle, or too much brake, and the opposite will happen. You can try an experiment
    in a long corner (Curva Grande at Monza, for example): go through the corner fairly
    fast, using about half throttle. Without moving the steering, let up on the throttle. The
    car should turn more to the inside (or it might spin). To master the simulation, you must
    learn to anticipate these steering effects and compensate for them with the steering
    wheel. One important note: since the throttle and brake are steering controls, be very
    smooth applying them. Jumping on and off the throttle and brake will give the same
    results as jerking violently on the steering wheel. At racing speeds, that is not good.
    Squeeze the throttle and brake gently.
    4) Don’t lift off the throttle in fast corners. This follows directly from the previous
    experiment. These cars are designed to be driven through corners on the power, so
    when you lift they will get very nervous and twitchy-which will likely lead to a spin.
    In fast corners (3rd gear or higher), slow down before the corner, then get back on the
    power as or before you turn into it. Stay on the power (not necessarily full power) all
    through the corner. If you still can’t make the corner, slow down more before turning.
    If you are using too little throttle through the turn, the car will be hard to control-it’s
    better to go in slower and use more throttle through the corner.
    5) Look well ahead. Try not to focus your attention on the road just in front of the
    car. Look down the track and visualize where you’d like to go in the next four to eight
    seconds. You will more quickly notice when things are going wrong-when only a small
    correction is required.

    #4 is most true for the wingless rear engine '67 GP cars simulated GPL (and now AC :) yeew just need the Brabham and got the 3 best cars out of that lot in AC), but not always for modern high grip cars. Although examples of modern season cars where IMO it remains true are the Audi TT RS VLN, and mid engine machines like the Audi, Ferrari 488 GT3, McLaren 650S GT3, Lotus 240R and Audi R8 LMS Ultra.
