Help a Tuner Learn more. Why

…do some tunes feel better but are not as fast it seems as ones that don’t feel as good?

EXAMPLE

I have been working on this tune lately and its pretty good but I’m wanting to push it even further and make it perfect(if there is such a thing)

I decided that having read a previous post that if you tune using the app and apply ONR RRs Tire formula and re-adjust the camber settings that this will give you a perfect tune.

So my tune based on feel is about a second faster than the tune from the app and other calcs.

The apptune feels better though/slightly. There’s just a lot less tire squealing and handling feels a bit better.

I’m confused?

I’ve deleted the app tuned version as its not as fast.

Is it my driving. I guess I’ve tuned around my own driving style with the feel one, is this it then?

Depends on engine parts/swaps you put on car to make it fast. What I said before makes the car handling as good as the car is capable of. You said it had less tire squealing & seemed to handle better. That’s a good thing. You probably could have beat your other build with a better braking point. Did your other build have stock tire compound & no weight reduction? I was not saying add race tire compound or full weight reduction. I was referring to making the car suspension and tires handle the best they can with in limitations of that build/car.

Most fast cars online/leaderboard might not have weight reduction & run stock tire compound. They also put the correct fastest possible engine swap/blower/engine parts to make the car very fast.

It’s a learning process. My comment before will have your tune handling as good as it can. I never said it would be the fastest. I don’t know why you lost 1 second. I was speaking in regards to chassis & tires (not necessarily street/sport/race compound). Take your current build & redo your tire pressure, alignment, anti roll bars, springs, & damping. I was not saying you got to add aero or different tire compound or weight reduction, then you probably had to lose some power because of PI. To have blazing fast tunes, you also got to know how to build the engine.

Here’s an example of a tune I made just for B Class Road America East in 35 minutes the other day. I spent a lot of that time on negative camber test driving. This isn’t the fastest. Some people have 3.8 handling. To low for me. This build is like a 4.0 or 4.1 handling. Some people’s build of this car has 900+ while mine has 800+. This is fast enough for me & this build won it’s first race online at RA East last night in No Collision B Class Hopper. Although I honestly don’t like cars that are a handful, this is if you don’t watch yourself. However though, with info I gave on that other post, this car is smooth on it’s handling. Well as good as a 4.0 car can in a turn lol. But alignment, sprigns, damping do have this running smooth in a straight line flat out. Wrong suspension set up & this car would be all over the place, even in a straight line.

My fastest time at RA East is a 01:08.947.
The fastest time for that car on Leaderboard by someone else using their own tune is 01:04:112. I’m completely happy with my time because most people I run into online aren’t running no where near even my time on that track. I ran into one guy who ran a 01:08 time at that track. However he was very inconsistent with his laps & came 2nd place. If he could have been constant he would have beat my 1:10 time car. This, made me do the Jaguar build, lol.

What matters to me? I used my build on that track in No Collision B Class last night. Fastest I ran that race was 1:09.272. My build is not the fastest. But is way faster than what majority of what people run in whatever car. I finished race 32 seconds before 2nd place.

That tune is a handful. I personally don’t like cars with handling like this. However I wanted a tune that can win online at that track. You have to brake way early & extremely slight throttle through a turn. Don’t stomp it till front wheels are straight. That is the only track I run that tune at. You have to know where to start braking at. I use ZERO assist & no line at all with regular manual clutch. Lastly, Thrustmaster TX no controller.

To go real fast, grip tires and weight reduction are an after thought for that track in B Class.

A comfy tune is often slower. I should know. Most of my tunes are the automotive equivalent of a Chesterfield. A fast tune is rarely dialed for much comfort It really is that simple.

My personal favorite fast car to use on speed tracks is 2011 Cadillac Coupe for B Class. The handling is a 4.8 & braking is 5.2 & 8.4 accel. with a top speed of 190 mph. I have no suspension issues & this car is easy to drive. I know just how hard to push it in various types of turns. I know when to exactly stomp the gas. It fairs extremely well online. Some cars might be a tad faster, but my suspension set up usually leads me ahead of them. You can have a fast car with a suspension that won’t have you all over the track.
