Im pretty lost here im going h22 on boost actually h22 wit a f22 block the motor is built block and head only thing missing is the turbo and ecu I really know nothing about hondata crome aem my question is which should i use and why

 

If you are not tuning the car yourself, which it doesn't sound like. You need to contact the tuner that you are going to go to and see what he suggests you purchase.

You can't go wrong with NepTune or Hondata S300.

 

but can i just buy the hondata so far all i see is a chip that goes into my ecu that i plug up to the car but the rest of te things that come with the chi. do i need them or should a tuner already have the microsoft to tune the car

 

Lol. Are you buying the unit used? Otherwise, it will come with all you need and take it to the tuner to make it happen.

 

It doesn't matter what software you buy. If you buy it new then usually you can get a basemap loaded onto it for your setup.
