ECU tuning

[CivicTypeR]

Hello all,

I have a JDM EP3R running completely bone stock except for a Mugen intake. I was just wondering if buying an ECU (e.g. KPro) and flash tuning my car at its current state would make any significant difference?

Not with just an intake dude

If you wanted exhaust and headers, do that, then consider tune

[CivicTypeR]

Oh okay. Just wanted to keep my car a sleeper though, headers and exhaust would make it louder.

loud if you vtak it, otherwise find an exhaust that is quiet down low and on idle.

The problem with tuning with minimal mods ie just Intake, you've only potentially derestricted the factory intake [Mugen intake should be an improvement from what I've seen] however on the other side of the power equation, the factory headers & exhaust [possibly your compliance CAT too] are bottlenecking the potential gains to be had by the intake. Result is the tune will only give you a more aggressive mapping against the factory's usually conservative tune.

Like NeedVtec mentioned, there are exhaust [Headers don't amplify sound as much as exhaust] that are quite civilised like the FGK Legalis-R [Link (http://www.fujitsubo.co.jp/prods/detail/000000000000001353/00000000000000003030/00000736)] and the FGK RM01A [Link (http://www.fujitsubo.co.jp/prods/detail/000000000000001354/00000000000000003031/00000736)] is louder but not by that much =)

Ohh okay. Cheers :)

of course a tune is worth it, but as the others have said, you need other mods

the Kpro IIRC has inbuilt settings for different mods so you should be able to tune/retune easily

[butterfingers]

I/H/E and then tune.
most efficient order of doing things to get power out.
still wont be anything extreme.

Yup, like butterfingers said, its not like a massive jump in peak power or torque, but rather with factory limitations removed, the last factory restriction is the factory ECU and its mapping. With I/H/E, the factory's ECU will most likely be out of its parameter to automatically adjust to the mods, in fact depending on the ECU, you could be experiencing loss in power due to it retarding and running rich =|

How about jsut getting the intake and catbakc alone without headers? Will that cause any problems with tuning?

[butterfingers]

wont cause problems
i heard ep3 headers are pretty good already
but you never know

Still will make your car loud.

Won't cause problems, just the potential gain might not be so great, depends on the factory EP3 Headers how much they can restrict... And the CAT too... Best to check what CAT has been installed, if its a cheap compliance CAT, it could choke your car like they did with my AE111. Change it to the JDM CAT and all was good in the world lol
