Ok guys, i have read just about every thread about this as well as tons of internet research and im still not sure what i want to do. I have a h23a motor completely built and im in the market for a stand alone. I have heard nothing but good things about hondata stage 4b, but i am really thinking of going with the AEM, it just has more to offer. The thing about the AEM is it is new, and i wont get the support that hondata gives out. I am led to believe in the next year the AEM EMS is going to just plain out kick everyone elses *** once people start getting them tuned properly and figure out all of the little goodies that come with it. Haltech is nice also, so is motec. Any comments, theories, or anything else is greatly appreciated. Thanks guys-

 

which ever one you choose, remember to k.i.s.s.

 

I have used Hondata, Accel, Electromotive and Speed Pro. By far the best system is the Speed Pro. 90% of every 9 and 10 second Honda uses this system. The same guy who wrote the software for Accel and Holley designed the Speed Pro. There is plenty of support available and it has been around long enough for the manufacturer to have worked out all of the bugs. We just finished a street car the other day that idled close to stock with 96lb/hr injectors with this system. Besides it's under $2000 with the wide band 02 sensor.

 

Thanks for your input, speed pro sounds like a good system. Where is a good place to purchase this at? Can i get some input from the guys running hondata's, AEM's, or other systems? Let me know how you like the system and if you have any regrets by not getting a diff stand alone. I'm afraid if i get the AEM its going to take me wayyy too long to get it tuned and that they still have some bugs to work out. Thanks for the input guys.

 

All's that I know is when I hooked up my hondata, the car started right up and ran perfectly fine. Even after turbo it still boosts/runs great, even without dyno tuning. I am running 550's so its not like I am still working with the puny 240's anymore.
From what I understand with the AEM you will have a very hard time getting the car to just start due to it being a newer system and not being able to provide too many basemaps to just start the car.
As far as the others, I dont know.
I love my hondata!

 

I am a Power FC user...yes it does have a lot of parameters to adjust, but it also gives full control over the engine....you can even get a PC interface if you are the F&F laptop type of person. I use the P-FC commander, which is nice. it can help pinpoint exactly where on the fuel/ign map your engine is at, at any given time. So, for example, if you experience bogging at a certain RPM or boost pressure, you can pinpoint the point on the map and adjust it accordingly....nice!!

The only disadvantages are not being able to tune multiple spots on the map at the same time (unless you get the laptop interface -about $300)...and that there is a smaller user base in the States (which isn't much of a problem really) so very little info or support...I would love to see more users to exchange parameter info...

ok heres the thing...anyone who tunes with the o2 that comes with the speed pro is doing it wrong. There is a 20 percent error in that and it doesnt act quick enough. AEMs first programing efforts lacked, although they are very soon to release new programing. Might be pretty bad ***. Motec is greet to, but it is very expensive. Heres a system to think about. It is called Autronic and is the exact same thing as Motec. For all you guys that want to be tunners, it has a learning mode on it that can set itself up. Although if you want to tune it correct, set it up open loop. The map sensor is built in and goes up to 50 pounds. It also has a built in boost controler and wheel speed sensors...everything a Motec is plus more. It is half the price though. If you want more info on this one,(my recomendation) http://www.dynospeed.com They are a autronics dealer. It also has data loging.

Oh by the way, Haltech is notorious for breaking.

 

I can get you one for the type r (b18c) for about $1050 (ecu+commander)

Miraiz, can you get the power fc for the h23a prelude set up? I am not too familiar with the autronic unit, but i sent an email to that shop that was recommended to see if i can learn more about it. I am really geared towards the AEM right now, but like i stated before im afraid of all the bugs i have to work out of it and i dont know how long it will take AEM before it is running 100%. Has anyone heard of the PMS system? I believe that is what it is called. I would like the motec m4 but i heard their units are in the 3-4000 price range. Thats just a little too expensive for a daily driver.

 

GudeH23a, Please contact R&D Motorsports in Charleston who is more than competent in tuning an AEM system. You might also pick up the latest issue of "Honda Tuning" in which there is a comprehensive article on the EMS. You can check a prior thread where AEM has offered $200 toward dyno time for the initial tuning.

no, not really.

anyway, because your in south carolina, i'd get the speed pro and go up to north carolina. the guy that tuned the turbo neon's there. he just tuned "littlebluecrx"s (honda-tech)motor and did a great job. jason went 10.92 in his street car, so the guy can tune.

 

HEHE make your own like me. It cost me about 95 US total. And BTW it is still working perfectly after 2 years of abuse on 6 psi of turbo power. This is all on a d16a6 CRX Si

 

Actually, the Haltech is notorious for breaking. We have a graveyard set out for them.

 

i know sensors occasionally break/go bad, but the system itself?? i know a few people using them for different platforms, including myself, and no ones had any real problems. at least for the e6s and the e6k.

 

I have the e6s. We have like ten cars running with haltechs. Mostly e6k's. We have a rotary pickup that is running 30psi on a stand still. Well the guy who tunes our car was the guy who did the set-up for sakura. He is the best in philly that I know of. What have you heard wrong about the e6s??? I got mine cheap.

 

It is not the sensors that have the problem with breaking, its the actual unit itself. I am just speaking from my experience and the shop I dyno at. There is an actual tombstone in the front that says rest in peice Haltech. There is like 4 units sitting in front of it. I know there are people who have bought them and they are running for ever. Im just speaking from my own experience.

 

Yeah Well one burn out on us like three months ago. It was the one in the rotary pickup. He was pushing 30psi and trying to go more. He got it replace. What model have been giving ya problems??

 

That's right, the wide band 02 sensor is not to be used for tuning on the dyno. It's purpose is to adjust the computers parameters according to different conditions, at different tracks. They aren't that expensive, we sell them for about $1900.

 

cant find any for the h23...only b18c and b16b

 

We have had problems with all the models of Haltech. It seems like they can not handle any kind of abuse at all. Had one catch on fire even.

 

That's weird because I haven't had any problems with haltech. It seems to work great as well as easy to tune.
