Has anyone tried the Fuelsaver wideband EFIE on a newer Toyota yet? I found it on this website:
http://www.fuelsaver-mpg.com/store/index.php?main_page=product_info&cPath=76&products_id=189.
I have built my system and have not got past the AFR. There is no point to me to have the system if I have to constantly reset the computer.

Well from what I know there are no news about anything on the AFR. I've had my system waiting for the update on AFr for a year now, about to throw it out. or maybe sale it.

Probably be better to ask some of those guys on fuelsaver forum.

The wideband AFR efie from fuelsaver-mpg.com WORKS - I have two of them, and they work like champs. Great product, great service, works when properly installed (follow their directions!).

You have pre cat wide band AFR's asd post cat narrow band O2's. In all likelyhood 4 sensors in all. They all have a decision in the fuel mixture. Today they are a bear to get around but with some patience it can be done.

You will need both pre and post cat enhancers as well as a MAP/MAF enhancer to get it done. There may be more but take it slow and let the ECU rewrite the long term fuel trim.

Hi

I was able to get a 30% gain in a 2007 by adding some resistance to the MAF sensor. I tried EFIEs all over and wasted my time. AFRs are a real pain.

Any info on req'd mods for 2002 Toyo Avalon? It has an O2 sensor on each exhaust manifold. k1sdl(at)aol.com
