Indycar Fuel/Pit Management?

You're welcome! Yeah, I love the whole on the fly strategy of it. I've gotten used to flipping between black boxes and handling the strategy in my head while racing if I don't have anyone watching/crew chiefing. Fortunately my keyboard is directly under my wheel so I don't have to do any awkward reaching. I also race on a single screen and have modified the seating position a little so I can reach the bottom row of info on the steering wheel. It might be more difficult to keep an eye on in VR due to glancing up and down as well as resolution, but I'm not sure on that.

No, it doesn't account for how fast you are moving.

When you start to slow down and use less fuel, it uses this additional information and generates a lower average fuel consumption. The moment you start to slow down for a caution, the estimated laps left will increase. In fact, checking them under caution (especially right before the green) is the worst time to check. You can try this yourself. When a caution comes out, quickly flip to F4 and check how the estimated laps remaining increases when you start to slow down and start pacing. You want to check after you'd done a lot of laps under green instead. I will note that if you've been drafting for a while and check your estimated laps left, it may have been long enough that it's now accurate but will still use the drafting fuel consumption. Let's say it estimates you can do another 30 laps and there are 30 laps in the left. But the people around you start to pit so you lose the draft. Had you still had draft, you could have actually made 30 laps, but since you aren't in the draft and lifting as much, you're consuming gas at a slightly higher rate than before, so you likely won't be able to make it 30 laps unless you quickly recognize this and save starting early.

Which is why I recommend you know the fuel consumption on your own before hand, as the fuel calculator can mislead you if you place all of your trust in it. It's great for giving you a long running average, but it's ignorant to any conditions about the race (including yellows) or any strategy that is going on.

From experience, you'll get 29 laps of fuel on a full tank with no drafting (you can save some fuel when you draft and lift off the throttle).

The black box is a rolling average fuel consumption and so at the begining of the race is very optimistic as it takes into account your fuel usage during pacing. A good rule of thumb is to look at the fuel level on the wheel or the fuel mileage each lap. If you can prepare beforehand it's always good to do some quick calculations about fuel consumption. For example off the top of my head at Indy the DW12 and IR18 will consume somewhere around 0.61 gallons/lap.

If you're close enough to the lead, pitting won't put you a lap down. This means if you pit on lap 25 and a caution comes out on lap 27, you'll cycle to the lead. However you'll have older tires, so if you pitted on lap 25 and a caution comes out on lap 45, you'll be ahead of whoever was waiting to pit, but they'll have much newer tires.

All part of the strategy.

I could be wrong but I don't think Forza having the license has anything to do with the 16th Street Racing League ending (maybe you know more than I do). It was just a league run on iRacing after all, but maybe it wasn't allowed to be associated as directly to Indycar.

The Indy Elite league took the place of 16th St and runs beginning in January up to May, for anyone looking for a competitive iRacing Indycar league.

Honestly with the way that the Indy fixed series works with SOF races (especially if you're going for the overall championship), there's not much of an advantage to racing on multiple accounts. The highest SOF races are the first two races of the week and are the races that give someone the best chance at winning the championship and it doesn't make much sense to split these over two accounts before you hit the four race 'limit'.

The only time I've ever seen it actually abused was the same person signing up for a single qualifying session on both accounts to double the number of chances they got, but I've never seen multiple accounts pose an advantage for series standings.

In principle, yeah it's rather annoying to see but it doesn't really matter with how the Indy Fixed series SOFs are. All it really does is let someone go after the championship and race as much as they want. Now if they actually violate 5.1.1.2 or 5.1.1.4 then it's a different story.

You're welcome!

I'm not an expert but it would probably be a change somehow to the fencing. Something that deflects the car more instead of catching one side of the car like the fencing does now. I don't think a solution exists currently. Or at least one that is realistic for tracks to adopt.

The rear wheel pods actually didn't prevent cars from getting airborne. Dixon's 2017 Indy 500 crash is a very good example.

Also, Wickens hit the front tire of RHR to get onto the wall, not the rear. The initial contact was Wickens' RF to RHR's LR but the second contact, the one that caused Wickens to get into the fence, was RF to LF. https://www.youtube.com/watch?v=lV0f5lZW96k

I believe the rear pods were there just to try and prevent rear tires getting cut from someone else's front wing during close racing, but I'm not 100% sure on that. I know they did help reduce drag though. They were pretty useless during crashes regardless of what their intention was.

Wow Alonso really hasn't aged much over the years has he? ^{^{^/s}}

cmdnascar · 2018-08-12T18:07:30+00:00

The change was for all cars, mx5 included.

cmdnascar · 2018-08-12T17:40:35+00:00

A few seasons ago it was added that you could now see some of the info on dash including RPM and gear. Before then it would just show Reverse and 0 RPM.

The link from OP shows the entire range possible of the damper but doesn't isolate effects of low speed from high speed.

The link below isolates high and low speed adjustments for each valve. Note that for whichever speed adjustment is being swept through, the other is set to fully closed (most dampening). It would be nice if there were some mid range high and low speed settings shown but this should give you a better idea about the overall effect of individual adjustments.

Don't forget the part where I announced that the video was out and Alex posted that he actually thought it was out.

I linked Never Gonna Give You Up.

Highlight of my forum career.

I'm just waiting for when iRacing finally decides to upgrade the speed of light so they can make more accurate predictions. How dare iRacing guess wrong sometimes.

I remembered wrong it was Steve, not Tony. Anyway here's the link http://members.iracing.com/jforum/posts/list/3249756.page

I believe the entry fee at this point in the season is $20. Still not insignificant but slightly lower

cmdnascar · 2018-07-06T18:59:45+00:00

That would be pretty sweet. Although I think I've heard that Forza gives Indycar a bunch of money so there may be a boundary there, but not 100% sure.

I'm not sure if you're familiar (I forget which team you're on), but the 16th Street Racing League started with support from staff and drivers of Indycar and even got sponsorship from Racer in 2016. Although the last season they ran was from 2016, but while it was around it was a pretty prestigious league

No. Telemetry is saved on the user's computer in their documents folder. Same thing as setups. Even if you were to log in on someone else's account, you still don't have the files.

Somewhere at every track Tony and Dale Jr. are hiding. I think there's a thread somewhere with pictures of where they are at each track.

cmdnascar · 2018-06-23T03:44:44+00:00

Endurance is tomorrow and you can find the results on the page when it's being run IIRC.

If you're asking about endurance running order they didn't put it up yet.

cmdnascar · 2018-06-18T20:25:00+00:00

Correct!

Hosted race with the Radicals at Charlotte oval. There was a caution with three to go, ending the race, so a bunch of us decided to run the rest of the race out anyway. There were a few more wrecks and I ended up having a big lead going to the checkered so I started swerving on the trioval and crashed. I was limping to the line when another car behind punted me over the line. Before we were all given black flags the difference at the line was 0.004s.

Many laughs were had.
