I'm interested in alternatives to AEM's EMS for my 99 Accord, while maintaining the flexibility and control offered by AEM. Simply looking for something that can be dyno/street tuned to reach the car's maximum potential.

In order to use Hondata/Uberdata, Chrome, or others, I understand I'll have to convert to OBD I. I know there's a conversion harness available somewhere, and I have to use a different ECU, but which ECU exactly?

What sensors, or systems might be lost by converting (as in the knock sensor)?

I've heard that all this can be achieved with a total cost of around $500?

I've got a few more questions, that I'll post as the topics come up. Any links would be helpful as well, since my search did not answer all of my questions.

 

you will need to convert to a 2-wire IACV to go OBD1 on a 6th gen accord.

you'll need a socketed OBD1 ECU (sorry can't recommend which one, P28 perhaps)

you will lose knock sensor functionality and your 2nd o2 sensor will also be useless (even more useless than it already is)

you will lose your OBD2 port functionality, which will be a bitch if you have to pass a computer check for emissions.

going this route also requires the use of EEPROMs for tuning - ie: when a change is made to the map, you need to remove and re-burn the ECU's EEPROM.

Ahhh... So that all seems to add up to another $500 worth of headaches, making me want to just buy the EMS.

 

you can get an ostrich and tune w/o the hassle of removing chips and burning and putting the chips back in, almost on the fly tuning.

-a conversion harness can be had for about $80
-a p28 ecu socketed and ready for uberdata/hondata/crome/neptune can be had for $140
-optional - ostrich $175

dont know anything about the IACV conversion, but losing the knock senor and 2nd o2 is no biggy.

but like notoriousb said, if you have inspection/smog checks it will be a bitch.

 

There's always GReddy E-Manage.

May not be the best, but it's still an option.

 

raceACCORDingly, can you elaborate on this 'ostrich'?

EDIT: Don't have to worry about any inspections/smog check here in SC.

bingo! that's exactly why I'm running AEM.

 

the ostrich is an emulator. it simulates a chip in the ecu. you can realtime tune with it. we used crome the other day for the first time on a civic with a greddy turbo kit. It is probably the best bang for the buck out there. The guy had less than $300 in a complete tuning setup, granted we had the ostrich and the chip burner
