Engine Management ECU's Hondata -- DC2R

What do people thing of Greddy Emanage piggy back system?

What exactly is the difference between a stand alone ECU, and a piggy back system, apart from a Power FC or the like, being a total replacement.

What are the pros and cons of each?

Pro piggyback..

Your stock tune still works. can install it yourself. (only if you know how), drive it to a tuner to get tuned.
cheaper
not sure what else.. but those are pretty major Pro!

Con piggy back
possibly less tunability??
limited, generally people who start doing hardcore stuff use standalone. generally...

Pro for standalone
well most of it would only show if you do hardcore mods.
more tunability?

Cons standalone
usually expensive,
most of them you goto pay someone to install and Tune a base map.


the only reason i put thoses ECu up is so people have a look at what else is outthere..

if everyone just kept saying Power FC and get Adrian to tune it.. its not really an OPTIOn anymore is it..

i dont doubt the power FC been a good bang for buck.
especially for small mods. but if somoeone asked for an OPTIOn give them atleast a few choices to look at.

hondata,powerfc,emanage are not the entire list of ECu out there! there other other affordable ECu as well. even some free ones if anyone dares try.. Crome or Uberdata..

with the standalones if you did it right the first time even tunning it for just IHE. later one if you did cams and other internal mods atleast then you already have the ECu. you wont have to change it.

assuming you ever plan on going further. most people are happy with IHE and a piggyback.

There are 2 types of "piggy backs" that I know of.
1. uses stock ECU for cold starts, water temp compensation, air-con idle up etc... and uses ignition and fueling maps from it's own ECU. Technically you could say it's a semi piggy back. (HKS FCon Pro, Greddy Emanage Ultimate)

2. adjusts the inputs the ECU see's to get the desired outputs. This will mean you are pretty much limited to the boundaries in the map. Basic I/H/E would never see these boundaries reached. (SAFC, VAFC, Emanage Blue)

Everyone will keep saying PowerFC because it's proven to be the best bang for buck. One thing not mentioned with some wire in stand alones is that specific sensors will need to be installed.

errr. isnt PFC open loop only?

apexi is out of business... therefore, they dont sell the power fc.. this doesnt mean u cant get it, but if u do and it fucks up on u, ur not gona get any money back (warranty or anything) i would advise the hondata s100, its what ill be doing when i get cams, itb's (i only got exhaust, cat, extractors atm and it is not really nessasery just yet)...

This isn't entirely true. It is my understanding that the parent company of apexi has declared bankruptcy. Apexi is, however, still operating as usual - i.e. producing and selling powerfc and a range of other apexi products.

I'm also not sure about the warrenty issue. However, with complex electronics, it was always my understanding they either work from the beginning or don't work at all. They don't have moving parts that are put under stress, etc, which break due to use. So from the very begining after you purchase it you should know if it's faulty or not (giving you time to claim warrenty). I could be wrong though.

a'pexi PowerFC's main advantages include price and the fact that many tuners in australia are familiar with it and can do a decent job tuning it compared to say HKS FconVPro, Greddy eManage etc..

when changing ecu i decided to get Mugen N1 as i did not have faith in any tuners in SA. unlike the eastern states there are almost no tuned hondas in SA, the local tuners mainly do nissans, with a handful of rotary specialists, and some working knowledge of toyota, subaru, mitsu etc..havnt heard of anyone having more experience than 1 or two hondas of any sort ie not confidence inspiring..the mugen n1 option is a simple swap and not tuneable. from my research it gives the best power gains compared to other 'plug in non-tuneable' ecu's eg spoon and j's racing.
disadvantage is that it cant be tuned and only suitable for light tune type of setup..but thats exactly what i wanted and i'm happy with it!

errr. isnt PFC open loop only?

IIRC it is closed loop at stoich and also when water temp is below a certain temp.

[tinkerbell]

errr. isnt PFC open loop only?

errr, no.

it is closed loop as well.

PFC runs off the oxygen sensor when water is warm and not at WOT...

i get 8l/100km on freeway and 10.5l/100 around town + about 25-35l per 100km on track...

often called a "DOA return"...

if a ECU breaks during use it is usually due to user error e.g. wrong impedence injectors, short circuit a sensor etc...

good to see a constructive thread about peoples opinions on ECU's...

myself, along with alot of others im guessing, plan of doing ECU sometime in the future and i need all the help i can get hahaha

I got Hondata S200. Love it.

I got it over the S300 because I don't need boost yet (easily optioned for $50 or so) and I don't need onboard datalogging.
