Jodi, can you read this, im getting CEL
Jodi, this is cut and paste to what i posted in the 6.0L forum, im trying to figure this out... what i didnt post, is this tune is you tow brake 60hp, and that untill i loaded your tune my truck has never thrown a CEL-check engine light - ever..... I do love the program, works great, just hate seeing the CEL pop on ... i have put 400 hard towing miles on it with no issues, but i have only drivin it less then 100 miles without trailer attached, and have thrown the CEL twice.... details below... both times i just went back to stock, fired it up and CEL was gone......... please help. Below is cut and paste......
I got a new tune i have been trying its a tow tune, tows great... i have towed the 40 ft fifthwheel over 400 miles with it through a few mountain passes, no issues... however twice now(no trailer) when just gentle driving around town at a stoplight or when just driving at constant speed the CEL came on.... two weeks ago was first time, i pulled the code it was a P0004 which i have deterimined is no big deal... today while going 5mph rolling down the street the CEL came on with no codes??? whats that mean.... Both times i just went back to stock program and as soon as it fired up the CEL was gone... ideals? thanks
