Hey guys, i'm just wondering if any of you haven't installed a Hondata ECU for Air/Fuel mangement. I'm looking to buy one for tuning on my 01 Accord 2.3L so that the engine can handle the amount of boost i'm running but I'm not sure which type to use (Hondata s100, s200, s300 etc). I don't know the differences between Apexi and Hondata... and i don't know if Hondata will fit my accord. IF anyone has installed one in his/her car either a Hondata or a Apexi, can you tell me which type will be good for my car and can i tune it by using a computer or take it to a professional. BUt tell me which one should work better and how to work it. Thankx

 

Unless you have a dyno you cant tune it yourself safely. Call Hondata to see what your application would be. You will have to convert your car to OBD1 which a Boomslang conversion harness will do the trick. I would go S300 because burning chips gets old after a while.

 

If you're going to have a professional tune the car for you, then I would recommend this:

1. Find a reputable tuner in your area. I say "reputable" b/c you can spend all the money you want on engine management, but if the tuner can't tune, well...
2. Consult with that tuner to figure out which system he prefers and is most comfortable/confident tuning with. After all, he's going to be the tuning.

 

is the car obd2 still?

are you looking forward to have it convert to obd1 so it would make tuning 120times easier? which is lead to another the following question.

is smog required in your state?

how much is your budget?

you cannot etune your setup, you need to dyno tune it by professional.
there's no universal formula for car tuning(yet, hopefully)
every motor, setup, driver's perference is very different.
some might want rubber burning torque over high rev'ing horsepower and vise versa.

if you need to get some tuning done in SOCAL, autolink(LA), autowave(huntington beach) are some great place.

see, i'm very lack on the Electronic devices... when i hear Map Sensor, Check Valves, Missing Link, OBD1 2 3 etc...i'm not really sure..Yea, my car has stock internal..i'm not really sure what kind of Map Sensor that would consider. I just happened to find a Local Tuning in my area (no, i live in Memphis, tN and he has been tuning Hondas for the past 15 years also. I found his shop off of Hondata.com. I haven't really talked to him cause his assistant said he will call me back on that one to tell me exactly what i need for my application and what i need for tuning. In the mean time, if you guys can explain what exactly i need and i'll compare to his Tuning tools to see if there's any bid dfferent in price as well as electronic devices.

LIke i said, i'm only using 450cc DSM injectors and FMU 12:1 and i don't know if i really need those parts at all for Turbo Set Up. I haven't installed them yet but i bought them anyways cause i saw most of the turbo set up Upgraded with bigger injectors. If anyone knows what i need exactly to have a COMPLET FUEL SYSTEM SET UP/ TUNING please advise.

 

I dont know about you but my 6th gen they said they couldnt run Hondata on it, something with the ECU...

If you can't find your answers there, then give up.

With an EMS, you won't need the FMU.
Fuel wise, you'll need a 255lph fuel pump, injectors (450cc DSM's will be fine on a stock motor), and a good adj. FPR (fuel pressure regulator). You may be able to get away with the OEM FPR.

 

you can get away with the OEM fuel pump too if you want to be cheap about it. a walbro is good insurance but a stock honda pump is fine for low boost.

it's OBD2. you'd have to convert to OBD1 and a 2-wire IACV then you can run hondata on a 6th gen no problem.

With Hondata you do not need an aftermarket regulator. You adjust fuel pressure through the honda-logger program.

 

what? how can you possibly adjust static fuel pressure (which is maintained mechanically) thru the ECU?

I am not 100% sure, but I have been helping a friend tune his car (he works at a shop that has a dyno) and when he had an adjustable regulator on it Hondata did not like it at all. So now when we are tuning the a/f ratio it is all done on the computer, nothing mechanical at all.

 

Adjusting the AFR doesn't change the static fuel pressure. You don't have to adjust fuel pressure to tune the AFR, it's always done thru the ECU. Your friend's adjustable FPR was just probably not working or not adjusted right.

I'm running 750cc injectors on the stock honda FPR, no problems w/ tuning, idle or drivability.

Stock FPR is ~43 psi at the rail and you really don't need to adjust it unless you're trying to squeeze extra power out of undersized injectors.

 

Ok like I said I wasn't 100% sure about that. I have never heard of people adjusting the fuel pressure when running Hondata, like you said it is really not necessary, but then why did you recommend him to get an adjustable fpr?

 

He didn't. I did. But I said he may be able to do without it. The reason I did suggest it was because I had talked to a few tuners before, back when I was planning to turbo my Accord, and 2 of the 3 different tuners said that they would like to be able to adjust the fuel pressure while tuning. The 3rd tuner didn't mention it.

I only know a little about tuning... at least not enough to do it myself. After talking to those guys, I was under the impression that, although not necessary, it would have been a nice option to adjust the fuel pressure. Then again, that was like 3 years ago. Maybe the art of tuning has changed a lot since then.

 

WHOOOs..Thanks for all the comments guy... Well, i found that that Hondata will work on th 6th gen Accord but i'll have to do a lot of swapping like harness and crap. Well, i found out one method cause i just talked to some guy who has an 01 accord also and he had it for 2 years running at 8PSI making around 213WHP. He told me to get either a S-AFC2 or V-AFC2 and get me a missing link and i can hook up the wires to the ECU 6 or 7 wires i belive and be able to tune it with my Electronic A/F gauge already installed. Good thing that i don't have to take it to a shop to tune it pro and that'll safe some bucks on me. But when i'm done tunign the AF system, i'll definately take it for a Dyno , will be running at 7PSI first and see how it works before going to 8PSI. (that's the max planning to go to). Thanks for all the helps.

nahh it's still like that, every tuner has their own techniques, that's all.

VAFC and missing link??? Do you mean along with your FMU, or without. If without, don't let that guy touch your car at all.

And this guy is going to tune the car against an AF gauge? Meaning a narrowband, light-show, POS gauge I'm sure.

On second thought, don't let that guy touch your car regardless. Narrowband AF gauges are USELESS for tuning.

I also caution against using an AFC <u>at all</u>. Here's why:
