HHO on a already modified car

hi guys,
i am getting a hho kit for my car. My car (over here in aus) is a holden commodore, it has a 6 liter engine which has been modified.
Mods are:
Cold air induction MAF disabled
bigger camshaft
also rear o2 sensors disalbled
and of course ecu been tuned, i think the timming has been advanced too

with the electronic side of things is where im stuck.
i see on here some of you guys use the a chip or the FS2 and just lug in and away you go. would a FS2 still do its job even if my ecu is already enhanced?

or should i just get a digital efie and adjust to suit hho when hho is running.

or what i was thinking, seeing as my ecu has been re programmed, get my tunner to write a map for when hho is running

Getting an hho kit for your car is a good idea. Adding some modification and car parts will help a lot in improving your car's performance.

I wouldnt do anything to the car. 6L would take a lot of Hydroxy. Youd need a 3LPM setup to need to get an EFIE for the front o2. If you just have a 1-2LPM setup youd notice an improvemnet and might not even need an EFIE for the front o2 sensor. I like the setup. Less electronic devies do make it much simpler to improve mpg.

Hi, i am not getting the meaning of hho?? is this water ?
