I've been using the fuel-savers.org website up to now because thats where I ended up buying my efie, thinking they know their product well and could answer any questions. They've got high praise from most everyone, not cheap though. I've been helped here much more than anywhere in getting the best results for my efforts so I wanted to give the people here a chance to weigh in on this situation.
I installed the efie and mistakenly used the map sensor at first, it threw an EWL (engine warning light) Mike said to not use it until the efie is fine tuned so its now off. Reset the EWL and set the efie to 200mv offset.
Car ran fine next day, so I increased to 250mv offset...fine next day, increased to 300mv offset, then decided to increase offsets by 100. When I got to the 500 -> 600 offset ramp up it quit increasing at 565. All this time it never set off the EWL again. I asked Rick (fuelsavers) and he questioned my install, thinking I didn't have the correct signal wire. After rechecking and retesting I do have the right wire. During this testing somehow the EWL tripped so I reset it.
As a last step last night, I decided to ramp up the efie while everything was running and hot...I ramped it up to 520mv and heard a click...reversed a couple turns and ramped up again and heard another click, so I stopped there and emailed the fuelsaver tech. I did ramp back the mv setting to 150, a point that they recomend as a good start point. During this whole last ramping up the EWL never tripped! The tech from fuelsavers says sometimes they don't.
I left the efie wires more easily accessable (shrink wrapped them before) figuring I may be going back to them. I'm gonna run some tests and see if the offset from the efie is being applied...I know it may be hard since the setting bounces around heartily, but an offset may be detectable.
You guys got any suggestions? I want to get this efie figured out before I go from the water4gas to the dry cell installation.
Lastly...I know some may think I was moving maybe too quickly in ramping up the offset (daily/after drive home for work). I realize the car "learns" from your driving habits the STFT/LTFT thinking. I had originally planned to ramp up consistantly until it tripped the EWL, then ramp down to an acceptable level...the higher the offset, the higher the mpg savings. Its at this setting that was gonna be the START point after the dry cell switchover. The HHO output from the dry cell is greater and much stronger than the brick in a bath design.
Any suggestions appreciated.
