Stuck in crank state
Hello there, new here but i recently got an fitech 30003 (go street 400 i think) installed last weekend. It was running great until last night, started sitting on 10.4 afr with the iac pegged over 100. I noticed it wasnt adjusting trim at all and was getting stuck in 'crank' run state despite the handheld showing ~840 rpms. Curious if anyone has some tips for me. Right before this it was running great with the IAC adjusted properly (3-8 was its range)
Usually caused by electrical interference. Move your blue tach wire and see if anything changes. Also make sure your battery ground is directly to the block.
Here is a video that may help.
thank you for the speedy response. i was on hold with fitech while writing that, after talking to one of the guys there he said its a known issue if you get a low voltage condition with an older firmware (t198h). Mine was running t198i and he said he hadnt heard of any issues of the 198i getting stuck in crank, but sent me over the most up to date software and thus far its seemed to have fixed it. If it happens again ill be double checking the tach signal/grounds. Sorry for the rather pointless post now if it stays fixed, but maybe itll help someone in the future.
Good deal
