Simple Question:

I'm hooking up a A/F gauge in anticipation of boost in the next few weeks. I'm leery of tapping into the ECM directly (I've seen the pinout on HLH0501.com)

Question is: Where is the best O2 sensor to tap? I believe it's a white wire if I used 'search' correctly.

I have ordered a FSM, but it's going to be a few weeks. The Hayne's and Chilton's manuals are no help (as always). I'd like to get this done today, since it's a simple mod. I already have boost and EGT gauges installed. You'd think A/F would have been first.

Any takers? Pictures would help if available.

 

N/M Got it.

 

That's an impressive collection of cars you got there. How do those Fieros handle with them big engines in them?

 

MUCH better than stock. I have upgraded the suspension significantly.

Keep in mind both the LS1 and the Northstar are all ALUMINUM. The stock V6 or I4 are all IRON.

I have actually REDUCED my curb weight by lightening in places that I could. I have also achieved almost a 50/50 weight distribution on both. Little things like relocating the battery... and big things like adding a fuel cell to the front of the car.

By far the best cars I have ever driven. I have yet to meet their equal.

I'm following the design a street-legal tubeframe mid-engined car based on the Fiero frame. Loaded without fuel: 1876lbs



I have the materials and no time... I'm using this body though:

 

I sold the Northstar BTW... guess I should edit my signature.
