Hey guys just pit a converter in my car and now my cel flashed at idle and it doesn't throw a code when I hook my scanner up any ideas guysi

 

check the history codes. usually a flash indicates a misfire if you have a smaller converetr it may cause a low rpm miss you will need tuning to get it cleaned up basically idle spped raised and misfire reporting turned off maybe. I am not a tuner but from watching some tuning this is what I have seen. Remember the converter rotational mass is meant to help get the motor to the next firing cycle with smaller converters the dyanmics of that change.

 

Yea that's What I'm thinking hopefully a tune will help but I love this Fti converter

 

yep FTI does some good work.
