Running good on AEM EMS PNP with 3 bar map and 550cc
I just wanted to inform everyone that is considering buying engine management that I have got my car (99 civic si) to run well with the AEM EMS after spending probably around 4 to 5 hours with it. About 4 hours worth of just reading and playing with the software and another 1 hour of either idling or driving. I have a drag III turbo kit running at 7lbs right now, along with 9:1 JEs and eagle rods. The head is stock.
I was very surprised at how easy the tuning was to set up the 550 injectors. Everything is very user friendly, its just scary to a lot of people because of all the options and parameters you can mess with, if you choose too.
I have no prior standalone experience.

Please keep us informed as things go on. If I ever go standalone AEM will probably be it... in the end its cheaper then hondata for my car odbII.

good job.........now turn up the boost.
Hopefully once I get it street tuned pretty well with the wideband, I will take it to the local dyno and maybe add in some timing advance back from what I took away, and of course play with the fuel while I am there.
I will be happy with 300-325 wheel horsepower on 15 psi and 93 octane and shooting for 350-375 on 22 psi and 116 octane. I will let you guys know what happens.

Re: Running good on AEM EMS PNP with 3 bar map and 550cc (CovertFI)
yeah you are right. how much did it cost you?
This is why I choose it over the hondata. The hondata is a great product with great support, but it is expensive for OBD II cars and it does not have nearly as many controllable things as the AEM, but for some that is good and others its not. Plus by knowing how to work the AEM for my car, I can help other cars that are not hondas, which the hondata of course is only for hondas.

One more thing I wanted to add is that I have emailed AEM 2 times about my system and their response has been to reply with an answer in less than 2 hours both times. They seem very eager to answer any questions. That is very rare in this industry.

Re: Running good on AEM EMS PNP with 3 bar map and 550cc (fatkid)
Good to hear someone else is happy with the system...what version of the software/firmware are you running. I just upgraded from 3.07 -> 3.10 w/ firmware v73 and there were some significant changes...the user defined units are a pretty nice touch.
IIRC the autotune feature is still not "implemented"...I had been told it was supposed to be in the newest release but I haven't seen it as of yet.
Keep us posted. I've been reading alot of the various auto forums as of late to see people's experience with the system...for those that are looking for more info I'd suggest searching on supraforums.com. It seems one of the guys at AEM has a supra and likes to post some internal docs and tuned maps for supras.
BTW, I have dumped the maps for my prelude onto one of my servers ( http://ian.clendaniel.net/car/aemems ) and was looking at possibly making a repository where people could post maps and possibly a discussion forum...if anyone wants to contribute/comment shoot me an email.

The AEM in conjuction withe a wideband O2 allows for autotuning itself. Set the Air fuel ratio you want and it will manipulate the fuel to reach it.
Hopefully once I get it street tuned pretty well with the wideband, I will take it to the local dyno and maybe add in some timing advance back from what I took away, and of course play with the fuel while I am there.

I am going to download the newest versions now on my computer here at work and then I might download them on the laptop at home later, well see. I would be interested in sharing maps and having a discussion forum.

Isn't O2 feedback is autotune? Jeremy Powell at AEM told me that O2 feedback is close loop operation. It stuck in my head for a while but then I kinda realized that if wideband O2 is in use, isn't O2 feedback will autotune the fuel map at any parameter even at WOT?
Like the AFR map, you set the A/F ratio value at any load and rpm. Base on that, isn't the fuel map will be tuned by O2 feedback? or else what does AFR map for?

o2feedback is an adjustment to the mixture in realtime but not really autotuning...unless I'm wrong the o2fb doesn't modify the fuel map, it simply corrects as it goes.

Re: Running good on AEM EMS PNP with 3 bar map and 550cc (clendaniel)
I see, so, O2 feedback will need to have the wideband O2 constantly plugged and be used at all time. Is it accurate and fast enough to conpensate at WOT?

Good to hear. 
7psi was fun, but I'm going to need another ride or three at 15psi.
