Question is can we actually overcome the ECU? I'm preparing to install and test on a 1998 Oldsmobile Regency. It has all the OBD2 stuff.
Will the Volo chip correct everything?
I've tested the chip it did not work for me. Get yourself a proven EFIE. Your Olds system is easy to overcome the ECU, it will take patient on your part, but with the help of others here with great sucess. You'll see good mpg gain. I recommend an EFIE from Fuel Saver (Digital Quad) model.
Does using manual adjusters work better than the Volo chips? Or do you have to use both and if so which ones?
Do not use botht he Volo and an EFIE. Manual adjusting will yield better result.
Let face it making HHO on the bench is one thing. But getting the benefits in the car is another.
Making it on the bence should be the same when install in the car or truck. It is the adjusting on the EFIE that will take time to find the sweet spot. To give you a good start, when you get an EFIE and identified the correct signal wire. Set you rear O2 to 250mv and the front O2 to 350mv. Drive with that setting for 300-500 miles. You should see a lilttle gain from that setting then report back here I have more to follow.
It seams that from 2007-2009 there were a lot of enthusiast in this technology. But it seams the numbers have dwindled down. I notice many of and probably the majority of youtube videos were from this 2007-2009 time frame.
I guess I wondering why the dwindling numbers and will I be beating a dead horse try to overcome the ECU?
It is because people who get introduce to the process wants a "turn key" system. You will not find that unless you are driving a diesel, even then you need to do some fine tuning towards max gain. then only then you have a turn key system, just minor upkeeps, like oil changes in your car.
The most challenging system are the Honda's with their wide band or AFR O2.
Thanks for any comments and guidance.
