i have a built d16z6 and im running a p28 ecu.
I wantt to put in a chip but i cant make up my mind.
i like chrome, and s300.

what will these do performance wise and engine management wise.

 

"chrome" isn't a chip, and neither is the S300... These are hardware/software programs for developing maps to either program onto a chip(for CROME), or upload to the installed hardware in the ECU(S300)...

Crome is the most basic (has it's flaws but is free)
S300 is much more advanced and has its price too..

Your best solution is talk to whoever you are going to have tune the car and have them tell you what they'd like to use...

Hondata s300 & Neptune are the way to go for the money.

Crome is out dated & not worth spending anything on...
