good/bad AEM EMS

if you want to spend money on engine management, i'd get neptune or eCtune when it's publically available, you already have an ostrich so you'd be ready for an eCtune. Neptune is only $450 US compared to the $1500 AEM EMS and the Neptune RTP comes with a real time programming/datalogging board that gets installed inside of a stock ECU.
I've seen some rediculously high WHP setups running on Neptune, but they're all on race gas.
Or if you feel like blowing a bunch of money on a setup i thought u wanted to get rid of get the AEM EMS. I haven't really heard anything bad about it.

the greatest thing about the AEM EMS is just the sheer flexibility of the system. my buddy had one on his car and it was absolute magic. that being said, it has way more features and capabilities than you'll probably ever use... you don't need anything as extravaggant as the AEM EMS. that sorta thing is best for total custom engines where hardly anything is stock... I know one project my buddy was working on was using individual coils on plugs instead of a distributor system for the ignition. but he's since sold the car.

well, was thinking that since it can do o2 sensor when not in boost, i'd get pretty good fuel mileage.... i know zeeman's good tunes will do that too (i've only had tunes from zeeman on my boosted setups, plus he built my motor... one of few i trust) - i'd like something with solid knock protection, and fairly easy to use software.
ebay has the ems' for fairly cheap, i bet the guys at jrp will give a better price on one....
seeking reliability
edit: i've been watching for ECTUNE for a long time...still nothing....waiting :\

I have to mention megasquirt. We are using it on our 87 MR2 supercharged race car, full standalone.
It's very user friendly, has tones of functions depending on what type and version you use. Has datalogging capabilities with auto anylizer.
Has huge support through the megasquirt website and forums. Lots of guys running ms on hondas and toyotas.
Has an excellent interface program.
Can controll boost, can run off O2, can do 2 step, can controll VTEC, can do what ever you want it to.
And it's fairly cheap compared to other systems out there.

if you want the best gas mileage you won't want the o2 sensor enabled.
Simply b/c with the o2 sensor enabled, the ecu will be using the o2 sensor feedback and adjusting the air/fuel ratio to stay at 14.7:1, nothing more, nothing less. If the o2 sensor is disabled you can lean the engine out even more, to squeeze a little more fuel mileage out of it. Typically, when a customer requests, i'll tune the partial throttle/cruise portions of the fuel maps to be around 15.5-16:1 AFR if the engine likes it. Ever since i've tuned my car to run 15.5-16:1 AFR at partial throttle/cruise my mileage has been better than ever. Now if you were to enable the o2 sensor (run closed loop) the ecu would be adding fuel in to get the AFR's down to 14.5-14.7:1.
With the AEM EMS you'll pay easily twice as much for tuning b/c it'll take twice as long to tune and there is that much more room for error if something hasn't been adjusted properly, since there is so much flexibility in the program. Not to mention is additional initial cost of the hardware/software. Neptune will do everything you need it to plus tonnes more.
Megasquirt on a honda?!?!?! Why, when there are already so many honda specific options to use. Waste of time/money if you ask me.
And Ron....my car has been running on eCtune now for a couple of weeks.

MS works very well. MS on a Honda? Why not. Yes there are many other setups already available, so what. MS is not as expensive as you think. If you want full standalone, it works very well and its a force to be reckoned with. I'm not saying it's the best way for everyone to go. I'm saying it's there, it works really well, it's flexible, and its not expensive.

wow, i've yet to see a honda that doesn't jerk/hesitate at anything much over 16:1.
All of the other softwares out the designed specifically for hondas have the same capabilities that MS does is easier to setup/use IMO.
Ron if you wanna buy the neptune RTP i've got i'd let it go b/c its just sitting here now that my car is running on eCtune.
I personally like using a stock rom editor and keeping the ecu OEM, for reliability and ease of use, and have yet to reach the limits of editing stock code, so until then (or until i wanna ditch the distributor and run a coil pack or individual coils) i'll stick with crome/neptune/eCtune/hondata and enjoy not spending much on engine management and having a very easy to use, reliable program/hardware.
I can completely understand using megasquirt on something where there isn't nearly as much support for stock ecus, something like a cavalier or MR2 i guess.

if so, it may be the route for me to go..or can we do ectune on my next tune mr zeeman? or would the neptune be a good idea ? (esp if i move and need to make any lil changes later?)
