First I set my EFIE to 375mv and I was throwing codes all over the place. The Trac ran rough & at idle, it was jumping around.
Then I set my EFIE to 350mv and it ran better but still not right!
I lowered it to 340mv. It threw 2 DTC codes (0133 & 0153 Heated O2 Sensor Circuit Slow Response) and it ran sluggish.
I backed them off to around 310mv (it fluctuates between 307 & 312 mv) and it ran better.
This morning I was at a stop sign waiting to turn, there was a car coming about 15 car lengths away. I hit the gas & the Trac choked! Like it was not getting fuel.
Driving down the road it just didn't "feel"right. I've decided to drop it again, this time to 275mv.
It idles much smoother. I will take it for a test run & see if this will resolve the performance issue. Then I will evaluate the MPG at the end of the next 100 miles.

FIXED the DTC Code Issues!!!!
Well the new connections are solid! That fixed the code throwing issue.
Tomorrow I'll re attach the EFIE and fire up the generator!
BTW I found something interesting about the EFIE.
With all the fluctuation the O2 sensor does, when I set the EFIE to .25volts
I thought that was what I was setting it at. Being now able to check the signal at the ECU
I noted if the EFIE is on, you will read the voltage the oxygen sensor is producing [b]plus[/b] the voltage
being added by the EFIE.
Lets say you set the EFIE to .25 volts. Let's also say that when reading the oxygen
sensor in the previous paragraph, you saw a fluctuating voltage between .2 and .7 volts. When reading the
computer's input voltage you would then see a constantly changing voltage in the range of .45 and .95. This is
due to the .2 to .7 volts the sensor is producing, plus .25 volts that the EFIE is adding.

Throwing DTC codes
I did some investigating today.
I opened the shrink wrap on the EFIE connections to make sure I hooked it up right. They were correct
a code 1151 or 1131 could be associated with a vacuum leak or an intake leak after the MAF or an exhaust leak by the O2 sensors. So I sprayed carb cleaner around the HHO inlet hose, all good, I replaced the hose with a tighter fit one. I was worried the EGT probe may have a leak & causing this as well. I took it for a ride & throw an 1151. Ok I disconnected the EFIE and connected it stock. Went for a ride within a mile again I threw an 1151. I came home and connected the multimeter to the stock O2 connections the passenger side was all over the place 150mv to 924mv and everything in between (BTW I am using a $900 MS7212 Mastech and it still bounces around) Then I tested the driver side 38mv to 89mv! It never passed 100mv, very suspect. I checked the connections & they looked ok. Still I figured I would replace the connectors to blades. Of course my soldering gun craps out (cuz I dropped it) , I have to use a junky tip solderer. Ok all the OEM connections are replaced, everything soldered. Took it for a 5 mile hop. No DTC codes.
So it appears one of my connections to the driver side was fubar. I soldered new connectors to the EFIE now as well. I will take a ride to pick up my kid from school (12 mile round trip) If I don't throw any codes then I will reconnect the EFFIE & see what happens then.

I found leakage & clogs in my system which would attribute to the crappy mileage.
I used my eudiometer to check my production at the intake. For some reason it was .25 LPM.
Digging I found several issues. First my lovely reservoir leaked gas from the cap. I suspected in as much as that was the only part that was not in my bench setup. I swapped it out for the other one for now.
I also disconnected the circulating pump since my cell is relatively cool. Ok so then I blew air into the line from the reservoir to the bubbler, nothing. Can't blow the air into it. Why? The stone is clogged beyond use. I replaced it and ran the truck.
I see real good gas production at the reservoir. I test it at the intake... 2 LPM.
The scangauge is reading better mileage but still not as good as without HHO.
Filled up my mileage went from 15.5 MPG to 12.4 MPG.
I also threw an 1151 & a 1131 code (lean condition) My EFIE was set to 338MV I suppose this is due to the fact that not much HHO was getting into the intake.
I have to play with the EFIE now, maybe set it to around 355mv.
