Ok, so thanks to ADs and Naacs (and 3 hours of testing !) we may have found a way to get tire change pit stops to work glitch free so bare with me.....works like this.... 1. Set up a TUNE ONLINE LOBBY (with COMPULSORY PITSTOP SELECTED) and go into the EDIT PIT STRATEGY tab.....The tuning and pitstop option is ONLY AVAILABLE in a tune lobby.... 2. Select the default setting (press X) and then you get the screen below.....Move the fuel slider to 0, and make sure that "symmetrical" is selected for tires.....Hit X to save, and you should then get a NEW saved profile for the BMW Z4 GT3 as well as a "default" setting (2 profiles on your screen) 3. I then deleted the "DEFAULT" setting that was there, so all i had left was the Z4 one, and made sure the it has "YES" under "ACTIVE". To delete the "DEFAULT PROFILE" go into it, the press triangle. you should be left with just the Z4 one. 4. hit O to back out to the garage screen after confirming your left with just the 1 profile....... 5. Do a quick 3 lap race with "COMPULSORY PITSTOP" selected, and the Z4 active......(remember you are in a "TUNE" room, so when you enter the pits you need to select "CLOSE" when the pit options come up on pit entry. 6. When you enter the pit bay, you SHOULD get a fresh set of tires and no fuel...... 7. when the race finishes, your BMW PIT STOP profile SHOULD BE SAVED in the background... 8. Change the lobby to NON TUNE and do a 3 lap race, again with compulsory stop ON 9. Go into pit lane on lap lap 1, (will be prompted with PITSTOP message). This time you wont get any options, but you will still get a tire change, confirmed by the noise of the rattle guns working......and no fuel... I am planning on doing a race run at laguna tomorrow night at approx 9 sydney time to help confirm that these settings work....We did 3.5 hours and about 15 short races last night and they all seemed to work with no glitches.....would be great to get a full grid with 2 full chats (me and @Ad2mny to host a chat each) so that would give everyone the chance to see how it works and help others in prac rooms in the lead up to Round 1... The way i would structure the races would be as follows (just to be clear) - races will remain NON TUNE as per previous seasons.... - fuel will be determined as per previous seasons, IE either real or slow to get the desired race distance / laps....so everyone will have to select 0 fuel in the pitstop options or you will get fuel and a time penalty in the race ! - "COMPULSORY PITSTOP" will be selected in the race regs, so if everyone has the correct pit strat selected you will receive fresh tires when you make your stop. - This opens up the race strategy as i will select a tire wear rate (probably real) so the tires will last approx 75% of the race distance, meaning the "pit window" would be anywhere between lap 10 and 30 of a 35 lap race.... - With "compulsory pitstop' selected in the regs, anyone who doesnt make a stop would automatically be DSC in the results.... All sounds a little complicated, but once you have your pit strat sorted it seemed to work perfectly I suppose we need to ask is it worth doing ????
