A couple weeks ago i installed the Split Second ESC1 on my 97 4runner S/C. For the first couple days, everything worked fine. The video below shows what is currently happening.

To explain what the ESC1 does, here is the info sheet from Split Second
http://splitsec.com/products/datapdfs/esc1ds.pdf

"The ESC1 EGO Signal Conditioner alters the signal from EGO sensors under boost conditions. Under vacuum conditions, it outputs a signal which is identical to the EGO signals that appear at the input. Under boost, it outputs an internally generated signal to allow open loop operation."

Basically under boost, its richens the AFR so you make more power and have less chance of pinging.

However, mine appears to be doing the opposite. It worked fine for awhile. Then it started randomly leaning out the AFR's. I disconnected it a few days ago because i didn't want it to run lean. I reconnected it tonight and i can't get it to operate properly at all. I have double and triple checked all my wire connections and boost lines. It runs normal and does not lean out with the ESC1 disconnected and when i go full throttle, it still goes into open loop fine and doesn't lean out.

Here is the video. Yes i know its kinda long.

I know most people here 96-98 owners here are not supercharged and even less(if any) have or are familar with the ESC1. But i figured crossposting it here wouldn't hurt.

Anyone have any input?
