I've heard good stuff about Hondata, it's a good deal cheaper then the AEM EMS if you go without all the extras.

Hondata is perfectly fine for what you have. Hondata is in the range of $200-$500, depending on what system you want. AEM EMS is around $1300, or so.

my hondata setup would run me about 1600 since i have a obdII car. I need the p28 with harness with boost. I have alot of mods in the car. So i think i need the tuning however............ im really stuck trying to pick one. They will cost about the same.

find a dealer: they can offer you better prices: They get them at discount and can pass the savings to you

Even if your accord is pre-OBDII wouldnt you have to get a Different ECU still. Also, Im kinda curious why if the AEM EMS is better for a heavy modded car with boost, wouldnt running high compression with boost be considered crazy enough for it, ive never had experience with either yet, just trying to learn alittle, correct me if im mistaken.

Yes with honda you have to chip a P28 bout a 150 dollar cost:
But if your pusshing high boost on the accord you better not have high compression, you should have already redid the block FOR turbo

Sorry, I do not mean to kill the thrill but I am trying to buy a hondata for a basic setup and the cheapest I have found with tuning is $1000. The Hondata is not so appealing to me anymore! The problem is the availability of tuners is limited in my state (2). So I guess they can charge what they want.. So I don't think the price should affect the decision. How do they compare in features and ease of use would be the main concern.

not really, people go with a setup of high compression and low boost as long as its tuned and done right.

...Doing a search on handata, and came across this topic... so i'll just comment on why i would like to go hondata.....
The thing that i like about Hondata is that it still uses the stock ecu from honda, it lets you keep the things that has made honda so great in the first place.
if you go aem ems then you are basicly get rid of everything and going with another companies idea and set up, now dont get me wrong i think either one is good. I have also heard that the aem ems is easier for the users to tune. the hondata takes a more experienced tuner.
i am not to the point where i can feel comfortable tuning it myself so for me hondata would be fine.
...good luck on your decision

Hondata sucks, nuff said. I'm not saying I like the EMS either, but I DOES seem pretty slick! Its like a baby motec and they keep adding things everyday to it. The one big thing it does have over using a stock honda ECU is the fact it can handle more than 4 injectors. Now you coudl hack in more injector drivers to a honda ecu, but you're talking way more work than its worth IMO.

Hondata used/continues to use quite a few incorrect formulas on certain items. Not to mention they're staffed by a bunch of tools and totally screwed a lot of the stage 2/3/4/4b customers with the s100/200 upgrade etc.

All I'm going to say is if you do your research and you're on the ball you can accomplish the same thing they do for free.... or near free. If you're not so much on the ball I really would sway you towards an EMS. I know a few people running them with great success now and it didnt take a rocket scientist to make it happen.

I think what bothers me most about Hondata is their insistance to keep tunes available only to the dealers. EMS users tend to share configuations and AEM encourges this as well. I'm not saying you should still tune on the dyno with/without help, but its nice to know you can get the thing up & running easy and without bribing a dealer.

Have you checked on tuning costs for the EMS? IT usually takes about 3 times as long to tune, so expect it to cost even more.
