| Blue 2007 Honda Civic si Left Side View |
So I have had the 2007 Honda Civic si sedan for four months now, I think it’s time to continue booting the performance. I already have a cold air and an exhaust system, people are telling me to aim for chips, so which is the best?
Answer: Well dont chip it you want a standalone ECU
such as AEM or Hondata. If you have the money go with Moots, but just be
prepared no base map is shipped and there is no easy tune. Best bang
for the buck is AEM, Or get a hold of Xenocrom tuning. The Si computers
are pretty much tuned already and if all you have is an Exhaust
and a CAI, don’t waste your money. Now if you are running under boost
or ITB’s, Bisimoto cams, adj cam gears, etc… Then start thinking about a
ECU swap. I ran a P28 Stock ECU on my Civic running Custom ITB’s a custom ground cams from Web-Cam Skkunk2 cam gears Bisimoto header, Stage 3 head from Exospeed, and only gained 20HP when I switched from factory ECU to a Hondata, and it took over 4 hours on a Dyno.
