If you're a NASA member, you should be able to get an account with Track Day Tire to get a decent savings on Hoosier A7, R7 and Toyo RR, RA1, and R888R. I believe they also take Toyo bucks, so if you're progressing through the HPDE ranks, you can get heavily discounted/free tires depending on your size.If you don't mind me asking, where do you get your racing tires from...?
I hope you're right, these 2nd and 3rd place trophies are looking lonely without their sibling... and I'm not a monster going to split their family upYou clearly have some talent. Wrangling a beast at 10/10 with non ideal conditions takes a lot of skill. I'm sure you'll finally get all the factors right sooner than you'd expect ;)
I haven't yet, still fighting too many things, but in about a month, we'll have our summer break where it's just too hot to race in our deserts and I'll have all this time going to waste and doing things like CAN mapping just might be a way to spend a day if I don't have anything else broken taking priority.Went through the entire thread - awesome effort.
Question (for my own selfish interest) - have you figured out CAN mapping (or another way) to get data from Race Capture ? I was thinking at least brake pressure and steering angle ?
Yeah, curious to see how that plays out. You're right that it's in that area. If you've taken your gigantic engine cover off, it's under that strange hard foam block and in a really hard metal jail cell of sorts, an attempt to shield it from a front collision and spray fuel all inside the engine bay at a really high psi. Auto Club just happens to be an e85 Coyote's biggest enemy, as coming onto the bank at a hard left will put all the fuel on the driver side, and if you're under 3/4 a tank, you're likely to starve it, under 1/2 a tank DEFINITELY starving it. Not only will you throw misfire codes, but if you're a total idiot, you can really make some bad things happen. The cam would be a bummer, but I think even if it somehow skipped a tooth or something, the engine would at least still start, but it'd sound like total garbage.Bummer. I believe the high pressure pump is driven off the passenger side exhaust cam. Hopefully the pump itself is the culprit and you didn't wipe a lobe from oiling issues.
The car runs 90% port injection on cold starts so it should still run (on pump gas), but I'm assuming the e85 needs more flow in all situations, so that doesn't apply here. Interesting how pump flow under lateral g's becomes an issue with e85. Ford used the 3.5 ecoboost setup with only one hpfp to save on cost and complexity instead of one for each bank. Guess you found the limits of their design, lol.Yeah, curious to see how that plays out. You're right that it's in that area.

My buddy checked for pressure at the rail the other weekend when I was running around, and said it just barely leaked out, so we're talking like 1# of fuel pressure. Replacing the in-tank unit, the FPCM, and now the high pressure pump, there's just about nothing left of the system, and the checking of fuses, relays, and voltages to the connector harnesses showed the rest working fine.
Honestly, I can not believe I've gotten this far without using it. I'll go as far to say that anybody seriously working or racing their car should at least have a laptop and the usb-obd cable. Being able to pull dataframes and watch the problems happen live is soooo valuable, especially when your problem won't trigger a DTC. I mean, at this point, I've bought two non-returnable parts that I didn't need to, about 25 gallons of gas for my tank, and a few hours driving up and back for something I could have known for a $50 cable and a free program. Here's hoping others can at least learn from my mistakes, they suck.Sad for the fuel pump but those DI engines have that problem happen from time to time more known issue on the F10 540i-550i's but hey you learn something new everyday. Hope your engine is fine. Also on the track I use forscan lite with the bluetooth odb2 that I use for data recording. And at home I have an ancient PC for more complicated stuff than reading trouble codes. Good for you that you learned how to use Forscan sorry to be in such situation. Enjoy your week.
I'm just guessing it's a freak thing, since they can run E15, and we're letting e85 work as a technicality somewhat. Sucking down 1/3 more fuel might be just too much demand for my system limping, but I'll know for sure when I swap the pump in and can verify what the pressure should look like on a normal start.The car runs 90% port injection on cold starts so it should still run (on pump gas), but I'm assuming the e85 needs more flow in all situations, so that doesn't apply here.

Thank you very much.Just finished the entire thread. Awesome read and build.!
