Has anyone ever ran into a condition where if you have a tune on a chipped ecu and you drive it and it drives fine, the next time you try to drive it the cel lights and car runs very rich? Does this sound like a bad tune, bad chip itself or a bad ecu?

 

When it runs rich, is the cel light on and can you rev past 4k?

 

only time I ever got a solid cell it was because I forgot to do plugin, enhancements and disable checksum.

It turned out to be something with the basemap chip, i think maybe a magnet got to it or something. Not sure but have it straightened out now. Thank you for the help guys
