I am visiting my brother in May who can answer your question.He is an auto mechanic and installed a hho unit on his truck.I am sure he knows the answer to your question.I will try to get him to post a reply here.Also I'm sure that that there are auto repair books on your car that will tell you how.If you don't want to wait till May.triffid

had to try again.triffid

ok it works now.hope this will be helpful.triffid

hello,
 I use the megasquirt system , low cost and will run any motor. hope this helps,

Hi - I noticed quite a few people running HHO systems on older hondas.  I used to do performance tuning a while back and there are a few ways you can accomplish tuning on OBD0 and OBD1 Hondas.  This will allow you to completely remap the fuel curve and ignition timing if you choose to do so.  The process requires you to "burn" bin data onto chips which you insert into a ZIF socket that is soldered into the ECU board.  These were meant to be used on high performance engines but since you basically have complete control over the fuel and ignition curves you can pretty much use it for whatever tuning you need.

NOTE: This involves opening and soldering to your current ECU so make sure you're comfortable with that.

http://www.superhonda.com/tech/honda_ecu_programming.html - This link gives some information on the socket you'll be soldering in and also mentions one of the few tuning softwares out there to accomplish this.

Software:
Turboedit - OBD0 honda ecus - http://www.turboedit.org/
Crome - OBD1 honda ecus - http://www.tunewithcrome.com/
Uberdata - OBD1 honda ecus - http://uberdata.pgmfi.org/ (seems to be down at the moment)
Hondata - http://www.hondata.com/
I believe they also allow datalogging to help with the tuning process.

As someone else mentioned, Megasquirt is also a good alternative if you're not comfortable with physically modifying your ECU.
SDS is another one which allows generic tuning (not honda specific) http://sdsefi.com/ - I personally have not used SDS but have seen it run some very high performance motors (500hp+) so I'd guess it might work in an HHO tuned atmosphere.

http://www.xenocron.com/catalog/index.php is a link to a place I used to use for chips and the actual rom burner also has a bin library for basemaps although most of them enrichen the mixture due to the fact that most people use these programs for turbocharged applications.
http://www.pgmfi.org/ - also a great source for information about doing tuning and fuel maps yourself and also a decent forum. (Link seems to be down at the moment but perhaps it'll work later on.)

Again, if you choose to look into the above products PLEASE do your research before jumping in to make sure it'll work with your application!  This is only meant to be suggestions! Tuning is critical to engine performance and if you screw something up it could seriously damage your motor.

I hope this is of some help to someone!

Hi All

 Check out the Holly Commander 950 system. They sell the computer separately.


I use it in my Motor home. you can set and forget or use a laptop wile you drive like I do.


Before you just mess with the timing you need to understand the Flame front of differant fuel types.

With gasoline, Leaner burns slower. so advance the timing

At 65 MPH my 454 runs 15.7 to 1 AF ratio  50 BTDC. as soon as the map sensor senses a load (hill or lead foot) the A/F ratio starts to drop ( run richer ) so the timing will drop also.

I have a knock sensor so I know if I am pushing the timing to much.


ALSO  GM and Toyota said the Fuel Cell cars will not work for them and they are going with Battery's.

So say goodbye to the IC engine in a few years.


Thanks, Rayco
