Default newbie EMU guidance..

Hey guys and girls...im sure this has probably been discussed before...

I will eventually be getting a complete exhaust sytem, and induction system, with a freer flowing element...hardly exciting. Once alll these items are fitted, i would be looking into getting a EMU..just to tinker around with basically..and smooth out the fuelling across the revrange and hopefully optimise the fuel and ignition maps. I know this wont make much power if any..its more about me wanting to tinker about with my car, and hopefully just get it running a bit sweeter. Eventually the AFM will be removed hence the reason i want the ultimate.

I know this probably sounds really silly to all you guys running turbo setups and serious NA setups..but does this sound like a reasonable way to start getting to grips with learning to map?

hey, EMUs are more easily available here in the UK. Not sure if i wana ditch the oem ecu either. My understanding is that the EMU will basically put a map over the standard ones (or something to this affect)..allowing me to keep the startup idle maps etc.

Are you asking what EMS to use or how to learn to tune?


Basics of tuning can be easily picked up here:

Its about the obd-I honda ECU, but the principles are the same.

Speaking as someone that's running a EMU.

Go for the MegaSquirt

The EMU itself is a good sturdy consistent solution.
The problem is the stock ECU.

Because it's a piggyback configuration you end up with a constant battle between the stock ECU and the EMU.

This gives very inconsistent fuelling in closed loop.
You can drive to work, faff about and adjust the fuelling, get it perfect (in closed loop) then drive home and find it completely different because the stock ECU has applied some different correction somewhere.


With a standalone you don't have this.

You have complete control so it gives a far more consistent solution.


The other thing is, 8 years ago the EMU was a half decent solution.
Today with car EMS's getting more and more advanced and prices coming down it'd be pretty much pointless to have to sit down and learn about tuning what is already an out of date system (EMU).

It'd be like spending 4 weeks reading up on windows 98, rather than the current MS version.


Lastly,
As more and more people move away from the EMU help and support is getting rarer and more difficult to find.
To the point that although a new software version has been released in Japan by Greddy over 1 years ago, no one has yet translated that upgrade into English.

MS on the other had has an absolutely massive support base that seems to grow daily.


As i say i'm running a EMU and have for around 7 years now, it's really a no brainer though a standalone is THAT much better.



Cheers
Mark

but the emu has a feature where you can force the stock ecu into open loop in the parts of the map where it would usually be closed, and then you can set the ignition and injection maps just as normal? so the ecu and emu wont be fighting?

or am i wrong??

just started playing with mine today lol...

yeah, it seemed to crap out about half an hour ago. we might get wrong for going off-topic here, but im just planning on getting a t25 running with FM manifold/downpipe (when i get round to ordering them) using the EMU. bigger injectors and stuff will follow down the line. check my thread for all the info once nutz is back up.

There is no built in feature like that, but if you were so inclined you could make a EMU activated O2 clamp.

In reality it'd make absolutely no difference as the stock ECU would still need to be in closed loop sometimes and whenever it is your going to get inconsistent fuelling.

Unless your given a EMU free of charge i honestly wouldn't bother, the difference between a well set up EMU and standalone is night and day, the standalone is THAT much better.

As i say i've run the EMU for a fair few years now and 10's of thousands of miles and as soon as i get me **** into gear i'll be replacing it with my Adaptronic.


My advice is, if your thinking about buying a EMU invest your money into a Adaptonic or MegaSquirt.
If you already own a EMU sell while there is a small chance someone might actually want to buy it.
