Ok, I'm currently running a 4-1 header on be obd0 b16 motor. This means I don't have any o2's plugged in, b/c as you probably know, there's no good way to run just one o2 on obd0. I've got my AEM wideband in the merged collector and i'm manipulating the a/f with a VAFC, which really doesn't work well as you can imagine.

What I'm thinking is this: from what I can gather, AEM widebands are heated, and will produce a narrowband signal to the ecu, while still displaying a wideband A/F ratio to the guage and datalogging unit (I'm nto using one right now). so theoretically, if I were to purchase one of these replica hytech headers, which conveniently have cylinders 1 and 3 merged, then 2 and 4 merged, and already have a bung on one of these collectors, I could weld a bung into the other one and rund the aem in one collector as the primary, and a heated 4-wire in another one as a secondary, connected to an ignition source for power, right?

I've searched and searched, and short of converting to obd1, this seems to be my best route. This way I don't have to spend money on obd1 hardware, adn I get a nice shiny new header.

Anybody see any problems with this idea?

 

Don't need to run a heated o2. OBD0 doesn't have provisions in the ecu for it anyway. Just use a standard single wire o2 in one bank and the wideband in the other. BRE can disable the second o2 very easily.

 

I've still heard that even when its disabled in BRE people are still having problems. In fact, not one person that I saw that disabled it did it with no daily driving consequences.

The reason I say heated is that because its so far from the block people say I need it...do I not? I guess I could try it with a one wire and if it doesn't work well try it with a 4 wire....

 

Ive never had problems and I ran with one sensor for years. Once I got tuned i just eliminated them both all together.

 

really??.....ok then YOU have to help me out, lol. Everybody talks abotu this **** and nobody really knows. SO I just need a BRE basemap with the secondary o2 disabled and it will run fine?

 

or wait, you ran with one sensor for years prior to using BRE?

 

I disabled the second o2 when I switched to BRE. Id advise that you sign up on pgmfi.org and read through the all the info in the BRE forum.

 

lol, I'm actually reading through it now. I'm not new to this, I've been researching it constantly sinc eI swapped the obd0 b16. My question to you is, were you able to get a one sensor setup working BEFORE you used bre, or only after? Thanks for all your replies by the way.

 

You NEED BRE to make one o2 work well. It never ran right before BRE with just one.

 

cool. thanks for the input. Now I just have to decide- new header with 2 o2's, or BRE with same header and one o2....
