– – These options include weight penalty, fuel percentage, and tire sets.

– – Short Parade Laps are now available!
– – This allows Race Sessions with a Rolling Start to have the initial “Parade Lap” (a Pace Lap/Laps behind the Pace Car) be a partial lap, as opposed to a complete lap.
– – You may select this option during the Track Options step of the Create a Race process.
– – – Currently, there is one track configuration that supports this option: Watkins Glen – Boot.

iRACING MEMBERSITE:

Website Data

Advertisement. Scroll to continue reading.

– For those who scrape the iRacing Membersite website for data and are using the endpoint behind the “My Series Results” page (/memberstats/member/GetResults) we request that you switch to the new endpoint “/memberstats/member/SearchSeriesResults”.
– – Key differences for the new endpoint are that it has fewer filters and returns all results unordered rather than pages of ordered results making the query easier for our system and requiring fewer calls.
– – Request parameters:
– – – custid (Required): ID for the customer whose official series results will be pulled.
– – – seriesid (Optional): ID of the series to limit results. Excluding pulls the customer’s results for all series.
– – – catid (Optional): The ID(s) of the categories to limit results. This parameter may be included zero or more times. Excluding pulls results for all categories. Acceptable values are ‘1’ (Oval), ‘2’ (Road), ‘3’ (Dirt Oval), ‘4’ (Dirt Road).
– – – evttype (Optional): The type(s) of events to limit results. This parameter may be included zero or more times. Excluding pulls results for all event types. Acceptable values are ‘2’ (Practice), ‘3’ (Qualify), ‘4’ (Time Trial), ‘5’ (Race).
– – – Either ‘seasonyear’ and ‘seasonquarter’ must be included, or ‘starttime_low’ and ‘starttime_high’. Our recommended approach is to use ‘seasonyear’ and ‘seasonquarter’ for initial pull of a customer’s data, then using ‘starttime_low’ and ‘starttime_high’ where ‘starttime_low’ is the start time from the last session pulled.
– – – – seasonyear: The season year for which to limit results (e.g. 2020).
– – – – seasonquarter: The season quarter for which to limit results (e.g. 3).
– – – – OR
– – – – starttime_low: Include in the results sessions which started after this date/time, in milliseconds since the epoch beginning midnight January 1, 1970 UTC.
– – – – starttime_high: Include in the results sessions which started prior to this date/time, in milliseconds since the epoch beginning midnight January 1, 1970 UTC. May be no more than 90 days after starttime_low.
– – Example pulling Oval and Road race results (note that this returns no results):

SIMULATION:

Race Servers

– Open Practice Sessions can now utilize Run-Groups.
– – Previously, Open Practice Sessions were limited to having only as many drivers connected at once as the max field size specified by the Series. For popular Series with small max field sizes, this led to having dozens of Open Practice Sessions running during popular time slots. The display of all those Sessions was cumbersome, and made it overly difficult to directly register for an Open Practice.
– – Open Practice Sessions can now utilize the Run-Groups capability that was only used previously during the Open Practice and Open Qualifying portions of Heat Racing events. Each Open Practice Session can now have as many full-field Run-Groups as will fit, plus a fractional “orphan” group that is no smaller than 8 cars, or half of the full-field size, whichever is greater.
– – When an Open Practice Session is using Run-Groups, the Race Server will assign you to an open slot in a Run-Group when you connect. While on track, you will only be driving with the other cars that are in your Run-Group, and the @DRIVERS radio channel will only have the chatter of the drivers in your Run-Group.
– – – Once you have connected to the Session, you may use the Entries page to switch to a different Run-Group, as long as it has an open slot. The Entries page shows what Run-Group each team is assigned to. Above this information, a user may use a dropdown menu to switch to a different Run-Group. This allows a user to join a friend in the Open Practice Session and be on the track together.
– – – Please note that due to the rate at which the track surface changes for Dirt Racing, Open Practices at tracks with any racing dirt surfaces will not utilize Run-Groups.

Dirt Oval Racing

– The average rate of water loss in prepared dirt surfaces has been reduced slightly.

– The overall starting Dynamic Track state for non-Heat Events has been made slightly fresher.

Heat Racing

– Fixed an issue that would cause a driver that enters a Heat Racing Session during Open Qualifying to not be assigned to a Run-Group, thus preventing them from driving.

– Fixed an issue where the Dynamic Track’s cloud shadow information could become inaccurate with certain wind directions.

Cautions

– Lapped cars are now allowed to pit with leaders at Superspeedways and long ovals to help reduce the length of a Caution.
– – Now, a Caution at these tracks will always be 3 laps long, even if there are lapped cars.
– – The tracks where this change is in place are as follows:
– – – Auto Club Speedway – Oval
– – – Autodromo Nazionale Monza – Oval – Right turning
– – – Daytona International Speedway – Oval
– – – Indianapolis Motor Speedway – Oval
– – – Michigan International Speedway
– – – Pocono Raceway
– – – Talladega Superspeedway

– Fixed an issue where an additional Caution Lap could be added to a Caution period if the pace car is before the Start/Finish as the leader crosses the Start/Finish.

– Fixed an issue where a driver could get an early free pass wave around at some tracks, like Talladega Superspeedway.
– – The Caution period now remains in formation until the pace car has fully completed it’s first lap, not the moment it hits the Start/Finish line as it’s leaving the pit lane.

Do Not Count (DNC) Cautions

– Fixed an issue with DNC Cautions at tracks where the starting grid is on pit road, and the field is large.

– Fixed an issue that could cause some cars that pit during the Caution to lose a lap.

Penalties

Advertisement. Scroll to continue reading.

– Drive-Through Penalties are now in place!
– – The Incident Count Black Flag penalty has been changed from a Stop-and-Go to a Drive-Through penalty.
– – Drive-Through Penalties may also be applied manually by an Admin.
– – – The admin command to issue a Drive-Through Penalty is done via the usual, “!black” command, but is appended with a “D” parameter.
– – – – For example: “!black <drivernumber> D”
– – To clear a Drive-Through Penalty, a driver must enter the pit lane under green track conditions with no other black flags, and pass through the whole pit lane without stopping in their pit stall. This action will clear the Drive-Through Penalty Black Flag as the driver passes the pit exit.
– – A Drive-Through Penalty cannot be cleared if entering the pits while the track is under Caution, but if a Caution comes out while a driver is already in the pitlane trying to serve a Drive-Through Penalty, the penalty will still clear successfully.
– – Getting a pit speed or other pit lane penalty while serving a Drive-Through Penalty will still clear the Drive-Through Penalty, but now the driver will have the extra penalties that were incurred during the process, and will need to clear those separately.
– – If the driver has other penalties in addition to a Drive-Through Penalty, the Drive-Through Penalty cannot be cleared via driving through the pitlane. It adds to the other penalties with the usual 15 second increase per combined penalty and must now be cleared via the usual stop and hold.

– Calls to clear penalties should now respect invalid disqualifications to keep the penalty rules state consistent with black flag handling.

Qualification Conduct Scrutiny

– The Qualification Conduct Scrutiny System has been updated to cause fewer false positive detections.

Physics

– Side-drafting parameters have been improved.

Tires

– Limited tire sets are now available in iRacing!
– – There may now be a limit on the number of tire sets you may put onto your car during an event. Tires may be replaced on an individual or group basis; for example, replace left-front only, or replace left-side, or replace all four.
– – Some Official Series will now utilize tire sets, thus limiting the number of tire sets you can use during an event.
– – When creating a User-Created Session via the iRacing BETA UI, during the Car step, users may specify how many tire sets are available for use by each car during the event. You may select a value from 0, meaning no tire changes are allowed, to 250.
– – – A Tire Set includes one new tire for each wheel.

– Tire parameters for Oval cars have been updated to a new archetype. This should improve racing for the following vehicles:

– Processing times for collision and physics have been improved on multi-core CPUs.
– – This fixes problems experienced on multi-core systems where previously the C-bar could overflow, causing the Simulation to fall behind.
– – Heavy loads during large wrecks and when multiple cars have severe damage should see significant improvement.
– – By default, the system will utilize half of the available logical processors (4 on a Quad-Core system with hyper-threading).
– – Users can change the number of processors by adjusting the “num_processors_to_use_for_new_damage” value, found in the “[Tasks]” section of the “core.ini” file.
– – – Values between 2 and 8 can be set to find what works best for your system.
– – – A value of 0 restores the default behavior.

Auto-Exposure Camera System

– Cameras now automatically fine tune their exposure based on the image they are capturing.
– – This system is only available when HDR is enabled in the Graphics Options Menu. It may be disabled by using SDR, or by altering the “AutoExposure” setting in “RendererDX11.ini” file.
– – There are two exposure modes, “Center” and “Normal.” Cockpit, Gyro, and Roll-bar cameras all use Center mode, they attempt to look outside of the cockpit by analyzing a fairly wide area near the upper-middle of the screen. Other cameras, including TV and chase cameras, use Normal mode and analyze the entire screen. For three screen configurations, these modes only consider the middle screen.
– – All cameras, even when auto-exposure is disabled, now support a manual exposure adjustment, this slider is accessible in the camera editor.
– – – To access the camera editor, press CTRL + F12 when viewing a Replay. This can be useful to fine tune the camera exposure for a screen shot or video capture, or just to set some cameras differently than others.

After winning their first title together in 1986, Earnhardt returned with a vengeance in 1987, winning the championship by nearly 500 points after throttling the field with 11 victories and adding a win in the All-Star Race with the fabled “Pass in the Grass.” Take to the track with one of Earnhardt’s most dominant racecars of all time and see if you’ve got some of “The Intimidator” in you.

– NEW CAR!
– – The NASCAR Ford Thunderbird – 1987 is now available for purchase in the iRacing Store!
– – – Prior to the advent of restrictor plate racing, Bill Elliott’s Ford Thunderbird, with engines built by his brother Ernie, hit speeds that no other NASCAR Cup Series car could touch at super-speedways. After breaking the 210 mph average speed barrier at Daytona in 1987, Elliott followed it up with a lap of 212.809 mph at Talladega later that year, before safety concerns forced NASCAR to slow down the cars. Get behind the wheel of the fastest car in the history of NASCAR, as Elliott’s iconic Melling Racing car has been painstakingly recreated for use in iRacing. Competition History: Fastest qualifier for the 1987 Winston 500, Talladega, Alabama, at 212.809 mph. This remains NASCAR’s fastest official lap ever. Winner, 1987 Talladega 500, Talladega, Alabama.

– – – Why race pick-up trucks? For starters, they’re arguably the most popular automotive vehicle in America, with upwards of 2 million new pickups sold every year in the United States. And they’re a blast to race, particularly the trucks of the NASCAR Gander Outdoors Truck Series. With 650 horsepower pushing their 3450 pounds around super speedways, ovals, short tracks and the occasional road course, NASCAR’s trucks are fun to watch and challenging to drive. Back in 1994, the very first exhibition race in the history of NASCAR SuperTruck Series competition was won by PJ Jones driving a Ford F150. More than 25 years onward, the F150 remains a staple of NASCAR’s truck competition, scoring its first title with Greg Biffle in 2000 and powering Matt Crafton to the Blue Oval’s most recent championship in 2019. Multiple teams now campaign the F150 in the real-world NASCAR Gander RV & Outdoors Truck Series, now’s your chance to join them on iRacing.
