do you now how many Nox is produced when you burn that 0.8 in a bad way ( more ) and what you produce when burning 1 gallon in the normal way? ( less )
i think you need to burn only 0,25 or 0,5 a bad way to come close to the 1 gallon of normal burn looking at exhausted stuff like nOx etc etc

I personally applaud jtcsd, Bob Wilson, The Force, ccdise, Ken@Japan and many others who are pursuing innovation. In my book, they are heroes with enough courage to continue their quest to make all of our lives better despite the naysayers trying to berate them for their work. I hope this post will embolden them to continue their projects and keep all of us informed of the progress.

I can only assume that the "thermocouple or thermistor" used in my 2004 are not equal to my friend's 2007 or mine are out of tolerance, I'm leaning more toward different production components.
I replaced the Potentiometer to 1K Ohms and the drop resistor to 270 Ohms and theses new values give me a range of 95 to 185 F to fool the engine temperature, just what I was looking to start in full EV mode for her short commutes with out starting the ICE

Mr Big
Could you make one me?
I will pay the necessary cost and fee provided I get DIY instruction setup and general operation procedure.
