Did a few searches but didn't find much. I wanted to know if any of you guys know of some good engine management systems that are still OBDII compliant. I don't care if it's a stand alone, piggy back, reflash..whatever, just as long as it's a good system. I've heard of the EFI PMS system but don't know much about it. Still trying to decide if I want to stay NA or if I want to turbo the R, but I want to know what engine management options I have first. Any help would be appreciated!

 

AEM EMS or just a VAFC...why would you wanna stay with OBD-II

Emissions I would go with the EMS, but it converts to OBDI.

 

does it???? you must live in cali., what year do you have, if you have a 98 this might be of interest: http://www.inlinefour.com/ecurep.html other than that (and still maybe) a VAFC would be right up your alley

 

hmmm, that doesnt make much sense. If you are planning a big buildup, either NA or turdblow, chances are you are gonna throw emissions right out the window anyway, even if you stayed OBD2.

and what do you mean by convert? Im running the EMS and it plugs right into my OBD2 harness.

 

vafc

 

E-manage.

That way you can actually tune ignition timing as well.

 

whatever you get, you can just plug the old stocker ecu back in for emissions...

 

I thought about emange. Seems like a decent, inexpensive way to go. But from what I have seen so far, I don't think Emanage can raise the rev limiter. Someone call me on this if I am wrong. With JUN 3 cams more of the power is made in 9000-9500 range. So that would be a must if I stayed NA.

 

That was actually another question I had. Could I actually put the stock ecu in just for emissions? I assume the car would run like crap for the time I have the ecus swapped, but if it passes....

Thanks for the link. I'm actually in Utah which seems to be getting closer and closer to Cali emissions every year. Anyway, I'm looking for a more tunable system than the VAFC. Something that can not only adjust air/fuel ratios, but vtec engagement, rev limiter, and possibly seperate octanes (ie. different maps for premium and race gas).

 

The car will probably run like dogsh1t on the stock ECU with a mild NA setup on JUN3s.

Depending on set up, the JUN3s can make power and hold it up to 9-9500 pretty easily.

 

Nope, e-manage can't raise rev limit. But no piggy back can, including the S-AFC. (except the now discontinued shogun).

I was doing a little more research and found another system called motek. Anyone know much about it?

 

You could get the E-Manage and the MSD 6al and have fuel/ignition and revv limit control, while retaining OBD2.

But why bother when it would be cheaper, easier, and better (IMO) to convert to OBD1 and run Hondata, and switch back when necessary.

 

MSD 6al can set a soft rev limit control, but it can't remove the stock one.

 

i don't think it will matter if obd1 or 2.. if they can't read ecu then it won't pass. i don't think theres a system for our cars that will pass the ecu scan.

the only one i know that has emmisions support is hondata for rsx

 

obd2 diagnostics can read a chipped OBD2 ecu, unless if the programmer removed some of the diagnostics (such as the 2nd O2 sensor)

and where can i get that chipped OBD2 ecu?

Do a search. Many people can.

HINT: Check out the link posted a couple of posts above.

I know (and recommend)Dynospot can reprogram it, so can Comptech, Yoshio, Ericks,Tectom, JET, etc...

BTW, I have seen a chipped OBD2b ecu also. Problem is not reprogramming it (its the same as programming any Honda ecu). Its obtaining the blank OKI 128 pin OBD2b chip that is the problem.

 

Does anyone have information on where to possibly get one of these blanks from??

 

I don't think it's locating one that's the problem... it's the cost! The obd2 rom is integrated into the board much more so than obd1 - so you have to buy that whole piece and it's hundreds of $'s, iirc. Dynospot Racing should be able to tell you exactly why.....

 

you're right.. its not that its impossible to do.. its the cost that makes it much more expensive than obd1

The "whole piece" is just the chip. I believe it was $150-$175 a pop for a one time burn blank chip.


Actually locating the chip is the main problem why it cost so much The Oki chip was made specifically for Honda use only. Unlike the OBD1 chips that have many uses in many different things.

Plus OBD2a (& OBD2b chip, which is a different chip) is no longer used in Honda ecus thus no reason to keep producing them. OBD2b blank chip was extremely hard to obtain even when Honda was still using it.

 

So really there is no reasonable option that will pass emissions by OBD II plug in testing...

...but if the car is tuned and will pass emissions sniffers, then you can be deferred to the dyno and get the sniffer test done?
