Super AFC Wideband and SAFC questions.

Wideband and SAFC questions.
My questin is, does a safc monitor a/f ratio, and does my ecu 88 TII with the rtek 1.7 chip accept wideband, how exactly does all this stuff hook, up and how does the wideband work, and how does the wideband, and safc work together????
Sry for all the question, but alot of this stuff has been on my mind for a while now.
Thanx

they both compliment each other.
The wideband simply MONITORS your Air / fuel ratios
The safc tricks the air flow meter into thinking it sees less / more air, therefore the ECU can add / remove fuel.
Ideally a standalone is your best option... but an safc is a simple and cost effective alternative. You won't get the results you would with a full standalone though.

I think wideband replaces the stock narrowband computer, I guess its also possibly to run both if you make a new bung for it, but there is little point. Widebands are used with standalones to more accurately read the a/f ratios. I don't think they work with a stock ECU, as they have a different voltage range.

I think it is fairly simple to tune with the SAFC, but I wouldn't recommend just starting to mess with your fuel if you've never done it before. Try to find someone that knows about tuning to help.
On a side note, from what I've read, widebands read on a 0-5V scale, while narrowbands use a 0-1V scale. I wonder if it would be possible to design a voltage divider circuit to bring the output of the wideband down to the stock narrowband ranges for use on with the stock ecu.

Here is something like you were talking about, says it sends narrowband data to your ecu, check it out...
