No mileage gains!!!
I am looking for some assistance in trying to get gains from my installation.

Specs:
1998 saturn sl2 1.9l manual transmission with 175000 miles.
Drycell that draws ~5amps. HHO output is T-d into the air intake just before the Manifold.

Replaced both O2 sensors, installed K&N air filter. Tried different weights of oil (5W-30, 10w-40).

I have the EFIE installed. I can tune for poor gas mileage but no increase.

I have to be missing something simple.

Any advice is greatly appreciated.

Thanks,
Mike

RE: No mileage gains!!!
This is where trial and errors comes into play. I get mixed signals from different sources. One says to run 8-10 amps others say 1-2amps.

This article is where I decided to adjust my amps to.

http://www.fuelsaver-mpg.com/how-much-hho-should-i-use

Before this I was drawing about 15-amps with no gains or losses. Read the section about "More is better".


Another question. What was your mpg before and after your HHO hook-up? I am trying to gauge what my target mpg should be.

Thanks

At 5 amps, you should definitely be getting good gains. Something is definitely wrong. Have you tried going through the HHO Debug checklist? You can find it here: http://www.dry-cells.com/dry-cell-debug-checklist

RE: No mileage gains!!!
I have many times. I have a scan gauge II connected to my car and it tells me that I should be getting better mileage then I am.

My EFIE is set to 150 in the front and 400 in the back. This is the starting point I believe you recommend.

I am beginning to wonder if the EFIE is actually working. The LED light flashes all the time (at different speed rates), this leads me to believe that it is working. Is there another way to test this?This is one I purchased from fuelsaver-mpg.com (Dual digital).

I can tune the EFIE to get worse gas mileage, just no gains.

Could there be something else wrong with my car? My check engine light is not on. It still has some get up and go behind it.

We recommend .2 or .25 for the rear setting. 400 mv may be too high and may cause the computer to throw engine codes. As for the front, if you're not getting gains, try other settings.

If the EFIE is flashing it is working, and you have it hooked up correctly.

Update:

With the new settings in place:

Front 02 Sensor 300
Rear 02 Sensor 250

It appears that I did gain about 10 miles to the tank. Engine now over heats rather quickly when in stop and go traffic. Double checked the AMP draw, it is now up to ~8.5 amps. It appears I really need to get a PWM put in place to keep the amp draw to about 5.

I will continue to monitor and update with results.

So, through another tank of gas. Yet again no mileage gain. I am at a loss on this. I am not sure what to do from here.
I will be performing a cleaning on the throttle body this weekend in hopes this will help. I am looking for any other suggestions I can try.

Current setup:

9 Place Drycell - Distilled water and KOH - Pulling just under 5 amps.
EFIE is configured for 300 in the Front and 250 in the back.

RE: No mileage gains!!!
Now that you have your amps working correctly, try increasing that front EFIE setting. Rear setting should be OK. The front setting is the most important for mileage gains.

The next thing to look at is the HHO Debug checklist. You can find that here: http://www.dry-cells.com/dry-cell-debug-checklist
