This image sums up my weekend. So what the hell happened?As of now… it looks like the hydro e-brake may have played a role. I was advised by a BMW tech that I could pull ABS fuses, and not trip the car into limp-mode. He said ABS electronics run independent from the motor, so I’m fine. WELL… ABS has 4 fuses… which (I think two) are shared with DSC. I pulled the fuses, and tested the e-brake. It locked up the rears… no problems, right? Wrong. I didn’t get a chance to really test the car out until I was at the top of the hill at Road Atlanta. The e-brake worked fine… but the car was totally in limp-mode and wouldn’t rev past 5K.I rush back to the truck, we replace all the fuses and reset it with a battery disconnect. The car ran fine the rest of practice. Problem solved, right? Wrong. My first qualifying run… I floor it out of the gate. The car was in limp-mode. I flipped a bitch right back to the truck. From this point on… we can’t get the car out of limp-mode. We reset the ecu, clear OBD2 codes, and think we get it out of limp mode… allowing me to redline 1st-3rd gear into 10a… then BAM… back into limp-mode. I almost threw the car into the wall (on accident) because of this shit. VERY VERY DANGEROUS.Why does something go wrong with this car EVERY YEAR at Road Atlanta? I’ve had this car since 2001 (new)… and it has never… EVERRR gone into limp-mode. Not once. Then I get to the top of the hill on race-day, and I’m stuck with an inoperable car that was totally killing it the week before during practice.Every project with this car has basically been a giant pain in the ass, and I’m pretty much furious with it. I knew running that e-brake was going to cause problems… it was too easy. Standalone seems to be what I need to bypass all the computational over-thinking I don’t even want in the car… but at this point I don’t want to spend any more money on it. All I want to do is thrash and have fun… but I am so pissed at the car right now.If I drove poorly and fumbled it… fine. I can live with that. But to have the car shit out on me and not let me make a single qualifying run is a spit in the face.
A killer snap through the shoe at Road Atlanta from the locals-only practice sesh.
