Before my final solo trials autox run of the day, I noticed fuel gauge close to E but the low fuel light wasn't on. Being a clueless turbo newbie, I ran again. Ppl told me black smoke came out (running rich to compensate) midway but I didn't know. then I got fuel cutout/starvation. Car/ecu shut engine off to my surprise; ppl said it was self preservation.
I restarted and fuel gauge showed an impossible 1/4 tank. From this point on, car has 0 boost and it can't go beyond ~2000rpm. Also, sometimes it now stalls when idling. All hoses seem connected still. Race friends say the car could be in limp mode. I got some help and gas and was able to crawl home. I think fuel gauge is showing the proper fuel level again at least.
I was advised to try disconnecting batt for a day; maybe ecu would reset from limp mode. Thanks for any help/tips!
