Ok so I've decided to go turbo on my 99 accord 5 speed. Ive got the kit (Drag gen3) and now I am looking for the correct boost controler and management sys to prepare for 11psi now and high boost in the near future.. I am also building the crap out of a 2nd engine F23a1 to replace the orig. as soon as I blow it up. I am looking at EMS , E-manage , and even hondata.. I am low on cash after buying the kit custom 2.5" exhaust high flow cat. Not to mention the pistons rings head studs machine shop billit rods. But I dont want to go cheap. because cheap horsepower dosent last.Help......

Oh and I work in the shop at a honda/acura dealer so I can do a little tuning myself.

 

Id say EMS or Hondata. If you go Hondata though you'll HAVE to go OBD1. With the EMS you wont have to go OBD1, you can stay at OBD2. Converting to OBD1 would cost more money since you'll need a OBD1 ECU and Harness as well as other things i believe such as the Intake Mani.

 

Ok Ive done the research on EMS and I have been informed it is difficult to tune. I don't have a DYNO within a few hundred miles so I dread the thought of retuning every month or so. I know there are some piggyback units that don't replace the ECM in its entirety and keep some of the stock settings to aid in management. Is the AEM EMS really worth the effort?

 

You can tune it with a wideband if there's not a dyno nearby.

should have gone open dp .....anyway...
edit: how much money are we talking here? tell me that and then i can give advice

 

Ive got about $900 left I can always wait a few weeks and save but my car is down and I am just dying to get it together.

Oh and I went with 2.5 high flow to keep it legal. and it will match the downpipe perfectly.

you haven't done enough research. i have a 99 turbo'ed accord too. get the AEM EMS w/ AEM wideband o2. you can do quite a bit of street tuning. you only need a dyno to get every lil pony out of ur engine.

give me ur exact setup. i'm on drag4 turbo kit w/ dsm black top injectors, stock honda map sensor. i can send you my calibration, then if you wanna proceed to get it fully tuned, you can then hit the dyno. all you would have to do is upload my calibration, set the TPS and sync the timing with a timing gun.

pm me.

btw, i'm running 7psi throught a MBC hallow a cat. with my street tuning, i run side-by-side with stock srt-4's, maybe a tad faster. have also run up against a 6spd G35(stock 280hp) with exhaust and rims, pretty sure he had other mods, but dont quote me on it, i never got to see them, but was almost side by side up untill 4th, by then i let off cuz i already lost....about 5,500rpms in 4th and he had maybe a car or a tad more on me, not much tho, i was happy! it was a sweet blue G35 coupe. this is in the DFW area.....ne one know this guy, i wanna know what he has done.

btw, u'll only need the dyno for tuning ur timing map, every thing else u can do with the wideband o2. i also reccomend going n surfing the AEM EMS fourms. my timing map is good tho, but its at ur own risk. i have had my EMS since January/Febuary, soo far my compression in each cylinder is @ 210psi, engine has about 22,000 miles on it. been boosting on this engine since it had 17,000 miles on it.

 

btw.....yes it is worth it!

if u needed to go back stock....like for inspection, it's a easy swap, unplug EMS, then plug stock ecu back in, of course u'll have to also change back to stock injectors too. if i can manage to stay off the throttle, i can get almost 350 miles with mix driving city/highway.

well worth it IMO.

also....why would u need to retune every month? u dont need to. the possiblities are almost endless with the EMS. BOOST CONTROL when i get to it is gonna be really cool.

if u can read, and you got common sense, u can do it, just read the instruction files, it'll take a lil to start to understand it, but you will. i did it, and if i did it, so can you .. expect to use alot of gas tho....i play with my EMS soo much its not funny.

 

At first I will be boosting the factory engine. The Drag kit didn't come with fuel injectors. do I need an upgrade??

Iguess I havent done my research.

and I been researching for a long time..

 

unless i missed, i cant believe no one suggested uberdata. its not an EMS, but i bet you can make it damn close. ive heard mixed emotions about it being used the the F22, but if you took the time to learn the rom editor and how to make the base maps im sure it would work perfectly. do a search for uberdata. may be a good choice seeing that you only have $900 left. you'll need to chip your ECU, a wideband o2 (unless you know someone who has one and can tune uber), a chip burner, and a laptop would be handy. im no expert on it so i could have missed something....feel free to bash me if i did!

 

You didn't miss anything. I'll be using uberdata when I turbo my accord. I'm still in the process of getting everything together but it'll end up being way cheaper than AEM or hondata.

p05 ecu==$15
chipping supplies==$20
Willem chip burner==$45
obd2 to obd1 harness==$80
wideband sensor and controller==$200-300

That's under $500, with a wideband. Aem's wideband set up cost around $500 all by itself.

And you can learn how to tune your own car instead of paying someone to do it.

 

dont compare the uberdata to AEM EMS, EMS will own uberdata by far. AEM's EMS is infinitely adjustable. btw....you dont need the AEM wideband, also, that big dollar number is for the gauge type, u dont need it. u also can just get any wideband and use that with the EMS if u want to.

yes you will need bigger injectors, you can go with DSM injectors, but dont expect to run more then 7psi on a t3/t4b, thats at about 80ish injector duty cycle, at 10psi ur maxing em out at 100% if u go with DSM injectors, get u a adj. fpr., u can run lil over 10psi with it, maybe 12psi.

btw.....to convert 98-02 accords to obd1, ur gonna need to do the IAC too!

 

"unless i missed, i cant believe no one suggested uberdata. its not an EMS, but i bet you can make it damn close."

no one compared the uberdata to the EMS. uberdata is FREE (to an extent), whereas the EMS is not (and is backed by a multimillion/billion dollar corporation that can afford to make it infinitely adjustable). BUT uberdata is a nice alternative that can bring much of the same results to someone who is going to run a low amounnt of boost. when he's running 15-20psi the EMS would probably be best. the point is that uberdata is a (hate to use the word...it makes it sound dirty) nice cheap alternative that lets you do just as much for the amount of boost most people will want to run. i mean honestly...would you buy an EMS for 7, 8, or even 10psi when you could go with uberdata and some time?

that, my friend, is a comparison

 

yeah i didnt really think of it as comparing them at the time, but i stand corrected

as a side note, and completely off topic to you
a real man can admit his mistake

 

so I guess I need more cash...AEM EMS.

 

I never said that uberdata was better than the EMS. I said it was cheaper<U></U>. Besides not everyone has $1200 to blow on an aem ems. It must suck to pay for something you can get for free.

that would be ideal. theres people that dog on it because of the price, and then theres the budget ricers that are just jealous they cant afford it. ive seen aem's ems do some wonderful things though

 

I think the only reason I am going to go EMS is so I can get down to bussiness on fuel management.. I want 400 HP. So I will need lots of room for adjustment!!
