For those of you that would like to install an EFIE - the ECM is under the passenger dash above the feet area.

It's Painless's fault!!! He made me build that!!! LOL :D :p

I just added a few more plates, hammered them as flat as I could & use 1/8" neoprene gaskets .....

BAM! An inexpensive genny!!

I have a 2000 Lexus RX300 and ive been looking to install hho for a while now. Im not comfortable building my own system, ive been loooking to buy a complete one but dont know which is best for my car. Since you have a Lexus i figured id ask you. I also dont know if i should go with the HHO mileage chip or the efie.

Hi, just reviving the thread, don't know if you used a Pulse width modulator. I see there's no mention of it, I have the same car, and am about to experiment with this project and see how it goes. Just looking for some feedback if possible.

Thanks, John.
