What kind of gas did you get?

A lot of cheaper gasses will make your car stink like that- like Arco is pretty cheap.. Never had any problems with Chevron.

Checked TSB's for civics the other day, rotten egg smell can be caused by a clogged catalytic converter. Just a thought... But either running rich OR a clogged cat, you're spitting too much fuel out the tail pipe. Probably due to the tune...

either bad gas, too much sulfur. or cat is going byebye. or your flashpro settings are incorrect. its not a good idea to use basemaps cause every car is different. dyno tune is the only way.

just check your local shops. usually most place with a dyno will know, but be sure they have experience with flashpro.

I used to get this smell on my car when it was new. How many miles are on it? The smell is probably the catalytic converter getting hot. When you got flashpro you were probably more prone to rev it out a lot causing the excessive heat. From what i've noticed its not a bad thing.
