Best ECU Mod?
I have an automatic 2004 Civic EX and have been trying to decide on what fuel/air management system to go with:
- AEM EMS
- Greddy E-Manage
-Apexi VAFC-II
-Venom 400
What do you guys reccommend, and will all of these work with an automatic transmission. I plan on getting turbo within a couple of months, if that makes any difference.
Thanks!

- AEM EMS not applicable to the 7th gen
- Greddy E-Manage definatly the way to go, Especially with a boost application.
-Apexi VAFC-II not that great
-Venom 400 this will advance your timing a bit.. bad for boost

Not available yet. The venom only tricks some sensors, and the vafcII gets reset by the ecu. So get the e-manage and the bypass that sends the ecu a fake "okay" signal under 1psi of boost.

Rep Power: 0 there is no point in getting an EMS unless you have some serious mods (i.e forced induction or severe engine work).. save your money and do your mods first.

unless you have some engine work done it would be kinda pointless to get any type of ems. put in some mods first

Rep Power: 787 vafcII is good for light mods. It doesn't work on 03-04 civic ecu. E-manage and ems are overkill, and venom plain sucks.

Rep Power: 0 that's weird, i can't get my vtec to kick in properly without the cel coming on with the v-afc2....
i was thinking about emanage, but does anyone think it's actually worth it for a n/a car?

Rep Power: 787 The e-manage has functions you'll never need like timing adjust, injector duty cycle, etc. Plus it's a pain to tune it. Most shops don't know how to do it right.
That's very strange about your vtec. Did you ever get a code reader and find out what the cel number was? That will tell you at least what's wrong.

Rep Power: 0 i've used the greddy system (with the e-01) on different cars and the apexi model. personally, i think they're both very good but I prefer the apexi. once you learn it's complicated system there is really no limit to what you can do with it. and if you got the boost controller they make it looks nice having the two together.
the e manage is easier to use, especially with the e-01 or the newer 02 model

Rep Power: 0 get obit by cartonics
obit is a great ECU designed for closed looped systems like the newer Civics
http://www.obitasia.com/piggyback_ecu_o-bit.htm
function include: http://www.obitasia.com/function.htm
recorded 15% bhp gain after dyno. i think is impressive for an NA car solely boosted by electronics & simple i/h/e bolt ons alone.

Rep Power: 265 im getting ems. and yes there is one for our cars. ems can do more stuff than e-manage. I would go with ems, but only if you have money and the mods to work it. I usually only see higher end vehicles using the ems, such as supras etc.
