i got a 2oo type sh and i want to run all motor car. i was doing research on what i should to do to the motor but i get confuse with stand alone system and a piggy back. so im wonder which one is better for me and what are the diff between them?

 

A standalone is programmable replacement for your stock ecu, while a piggyback works with your stock ecu, modifying your ecu inputs and/or outputs. In your case, the use of a standalone would cause your ATTS to not work. To function, the ATTS requires the stock ecu.

 

standalone would be better for all motor

 

you are screwede by the atts. nothing out there offically supports it.

i will be working on a turbo SH in a few months (waiting on parts) that will have the aem ems. i am going to make it work. not sure what im gona have to do but ill figure it out.
