fb turbo ?
 

My friend has a fb with a s5 13bt in it. It runs a haltech e6k. It ran great from the time he bought it until about 2 months ago. We were out driving it and stopped at walmart and were just showing some buddies under the hood. My friend wiggled the vacuum line to the map sensor trying to see under the uim and it just started running completly lean. It wont even read on the a/f gauge, just lean. I thought that maybe a particle or something went into the map sensor so we went and got some vacuum hose and replaced them all. Still nothing changed, just real lean. Its so lean that it just runs like crap. When you rev it its lean but right when you let off it richens up then back to lean. No matter the rpm it just stays so lean it wont even read on his Aem uego. Its a gm 3bar map and thats what i run on mine so we went and got mine. No luck. Same problem. Only other thing is the tps controlling fuel. We are unable to hook up to his ecu ever since he got it. Wants a password and from my research you have to erase the map to get by that. We dont have a copy of the map so we have not gone that route yet as it was tuned by Ray Wilson. Its almost like it lost the tune completly. We are stumped. I told him not to buy a tps until i asked on here because wouldnt we have to calibrate the tps via ecu anyway? Anyway if anyone can be any help that would be great. I dont need any nonsense in this thread either. We have tried everything we can without having to erase his map to link to ecu. Any help would be great guys!

Thanks Skyler

WOW. Nobody has any ideas? All that happened is the vaccum line to map sensor got wiggled and it started running extremely lean. Weve tried all new vaccum hoses and a different 3 bar map and same problem???

Datalogs would help

I know they would. They would be great!
