I just got a datalogger and need helpreading some of the stuff. When idle or driving my intake airflow rate always stays at 0. Is that normal also both o2 sensors read erradic. They jump from 80...800...120...760...ect. The only time it read a steady number was when i punch it. One read 940 the other read 960. upgrades are 14b turbo, manual boost controller,3' downpipe straight threw to muffler,255 fuel pump,turbo intake,safc2,pods...ect. Engine has check light on when had it checked out it said maf was bad. Car runs like timing being held back. Got front mount for it and the gm maf is on order. Any input would be appreciated.
