Which Device First

[Pit-Man]

OK, I have a sound system to produce the hydrogen on demand, which sequence of order would you suggest that I use to start improving the tunning, I would rather tune them one at a time to quantify results and limit one time costs. What order would you recommend that I purchase units to tune the following sensors:

MAP
TPS
MAF
ECT
IAT
O2

O2 is the first sensor to treat. You'll get the most gains from treating it.

After that MAF. But note that most of the other sensors can be treated with a resistor or a pot, maybe a few parts. Very cheap. So cost won't be a factor.

I checked in my Chilton's manual and the wiring diagram is listing my sensors as "Heated Oxygen Sensor" with four wires, in the replacement instructions they are also described as oxygen sensors. I wanted to check with you before ordering your "Dual EFIE Deluxe" product to make sure you feel it will work on my 200 GMC Sierra truck, what do you think?

Yes, it will work. The other types are either 5 wire, or called AFR (Air/Fuel Ratio) sensors. They don't call them heated oxygen sensors. You only need the Dual version if you have 2 upstream sensors (before the catalytic converter).

Thanks Mike, I'll place my order.

Mike I have two vehicles I want to convert. One is a 1999 1500 Chevy Suburban with the 5.7 lt engine. Which sensor should be used on it?
Second is a 1998 Chevy Caliver with the six cylinder engine. Which one for it?
Thank you,
Joe

Will you be offering an EFIE for those vehicles that have AFR's and funny O2 sensor inputs (like FORD)?

What ford do you have?

OH great , so Ford has issues with tuning the EFIE ...

The more the read the more the worse it gets ! I have a 99 ranger sure hope I'm not wasting hours of my time adjusting something that doesn't do a darn thing for me

I have a 2008 Ranger, 4cyl.

And if you think Ford is bad, wait until you try working on a Dodge/Chrysler product....

IMHO, stick with GM, at least until more info comes in.

Also, I relocated the wife's IAT sensor from the fresh air intake tube to just dangling it below the tube so the radiator fan blows on it.

Scangauge indicates the inducted air went from 95 to 137F.

Fuel economy seems to have gone up 4 MPG, but it's way too soon to tell.
