I agree with Chris, why anyone would go through all the trouble of all that motorwork and use a piggyback system is beyond my mere mortal comprehension.

 

Not just a piggyback, but a piggyback that cant control timing.

 

To be honest guys, it boggles my mind to drive my car on a stock ECU and a VAFC, at the same time minus an occasionable stumble in the fuel its really not to hatefull at all for 300 bucks. The motor will defenetly get to 9k after its broken in. Unfortunettly today i culdnt drive it, the battery is shot, i ordered an Optima yellow top today, i figure its a little more expensive then stock but has more cold cranking amps 500 opposed to 410 stock which i hope will help the start up. It will be here tommorow after i get out school. If the weather is good im going for a nice long drive tommorow. The reason i cant drive more then about 100mi. a day is because i just dont have that kind of time to go on cruises like that during the week.

thanks

Well I'll offer my two cents... I thin you should be running a stand alone on that engine as well. A stand alone and somebody that can tune it properly, will be the safest thing for the longevity of that engine.

You have significantly changed the dynamics of that engine. The rod/stroke ratio, piston speed, VE, etc.. Even with a piggyback, the stock timing maps probably have way too much timing.

I have some experience with the AEM EMS on two different civics, one of them is my daily driver. It's easy to get overwhelmed with AEM's software and it seems to still have a few bugs.. but their support has been pretty good, they won't help you tune it over the phone...

I would consider the AEM EMS an entry level stand alone. I have been researching what it's going to take to set up either an AEM or another stand alone in the s2k. I do know that you will need an extension harness because the case of the AEM unit will not fit in the stock ecu location.

If you are interested in learning more about tuning, check out:EFI University

I have attended their 101 class and am looking forward to attending their advanced level class.

 

cool stuff. congrats


i also agree that you should go EMS.

 

any pics during the build up?

 

I would always recommend the AEM EMS with a modified engine. I guess a K series Hondata could work but is it worth the conversion.

Although I can't help thinking that, excellent components and engineering aside, it is just an F20C displacing 25% more volume per cycle. So would 25% larger injectors on the stock ECU come close to tune? 440cc is pretty close to the mark and you can fine tune pretty well with an E-manage or even (am I even saying this) a V-AFC. No, I'm going to stick with the E-manage as my minimum suggestion as at least it gives you control of timing.

Is that Val Kilmer?
