Hi, i'm new to Turbo stuff. Need some experts to help me out
If I turbo charge my 2004 EX 1.7L SOHC civic, do I need a piggyback ECU to retune the A/F ratio? Or change to a new programmable ECU?

you need to get a fuel management program......most decent turbo kits come with them. And also its ALWAYS a good idea to get ur car tuned after doin a turbo.

 

yes, you will need an ecu upgrade, either stand-alone (completely replaces factory ecu, not newbie friendly, requires dyno tuning, or non-dyno tuning by an expert), or a piggy back, something like the greddy emanagae, or i believe edelbrock is also including some sort of piggyback with their new kits. i have heard good things about the edelbrock kits, i would swear by greddy, but the only thing that sucks is, imo the emanage sucks, i like standalone however, so my opinion does not count, also, the instructions, if you get them, are in japanese. ouch!

 

Thanks for the infomation.

the s200 from hondata is good too.

 

a V-AFC from apexi is the piggy back controller you need but u need a stand alone boost controler also, which usually comes with if u buy a complete kit.(i think u knew that)

 

in my experience with civics, i have never used the hondata, but am looking at them for a possible solution on a 97 cx with b16 swap. anyone who has experience with them? love em? hate em? let me know

 

well anything tunable is better than something that is not.

 

from what ive heard, hondata is pretty reliable, id either get that or the VAFC (or VAFC G2) or the s200, all basically do the same thing.
