I am looking for a decent engine management, for a turbo setup....I keep seeing stuff about hondata and neptune? anyone have a preffered setup for tuning....

 

Everyone has their own opinion on each ems.
Your best bet is going to be to review all of the systems your self. Such as options, interface & most importantly what your local tuner supports if your not tuning your self...

The best systems on the market: Hondata, eCtune, Neptune.
They have the most stable software, best features & support.

 

Ectune for the well develloped software and serial connection with Innovate product, no more O² sensor offsets
Hondata is a bit more expensive
and sorry never use Neptune, i hope i will

 

neptune connects with the serial as well

 

hondata s300
you can update the s-manager......>3
check out first w/ your local tunner
