I USE win 7 and win 10 is used by others, so you will have to update your opinion on operating system
As far as “GLOBAL” adjustments made by handheld “tuners” there is no fair comparison
Hand held tuning is not the same as opening memory addresses on a memory chip....you are on PID level with a laptop, and i think prom uses a laptop interface?
We can debate WB and NB usage, but that will get no where, the math is done within the chip on both anyhow
And the EECIV does not use NB info as in the fast and furious.......the strategy drive lambse around stoic for catalyst usage, the changes seen are then corrected for
It’s a precise and effective method of adaptive fueling, you can verify it with a third party WB as i and most do.
You have never said what EEC system you are using, Which one do you have?
I don't think a narrow 02 can't work efficiently. It has been proven it can.i just feel there is better technology out there and if I am going to spend money on buying an engine management I would like to get one I feel will work best for what I am trying to achieve. I an open to considering an EEC based system, but all you have done is try to convince me it is the best way to do it. Rather than give me info on which EEC systems you think would fit my needs and which ones still have a lot of support, as alot of them do not have the support they used to have like I have said about Anderson and the PMS.
I think a wideband is a better though. Based on what you have said I get the impression you don't think a wideband ECU can tell the exact A/F ratio.
A coolant temp sensor sends voltage, based on the volatge the ECU knows the exact coolant temp.
A intake air temp sensor sends voltage based on that voltage the ECU knows the exact air temp
A mass air flow sensor sends voltage to the ECU based on that voltage the ECU knows the exact air mass
A throttle position sensor sends voltage to the ECU, based on that voltage, the ECU knows the exact throttle angle.
A wideband 02 sends volt to an ECU, based on that voltage the ECU knows the exact A/F ratio
A narrow band 02 sends voltage to the ECU, based on that voltage the ECU can only tell if it is at stoichiometry, leaner than stoichiometry or richer than stoichiometry.
