QUES; 2000 s10 2.2 LN2 flex fuel; wideband connect thru EGR.
Thursday, May 22, 2014 3:00 AM
I have HP Tuners Standard & I'm hoping to connect my LC2 Wideband thru the EGR pin in the ECU. Hopefully somebody will have the info I need & help me. So what I've read, & i just want to be 100% sure, that I connect the Wideband thru (pin#19c). I atached a pDF of the ECU pin-out of the EGR. Thanks if anybody can help.

As long as you have a +5V signal you should be good. I personally have never logged though the EGR wiring, but I know a few of us have. Also, you may want to use 32 instead of 19....not sure if 32 or 19 is the correct one.

Personally I would go through the AC signal wire, which is also a 0-5V signal, which I believe is 34 if I'm reading everything right.

Thanks man for the info. Yeah if Im not 100% confident with going thru the EGR then I'm gonna Def go thru the AC.
I'm guessing 19 cause of what I read on a diff thread but I am gonna try 32 & 19. I'm pretty sure it's 1 of the two. Thanks man.

Just installed the LC2 tonight. I ended up running it thru the 19B pin. On the 2000 ecu it's the 19b pin compared to 1998 19c pin. It's the EGR pintile position pin. The 2000 ecu doesn't have the EGR but there is an empty pin where the EGR used to b. I also tapped into the pink ign wire out the back of the ecu & i put a 15A fuse in line. It works like a charm. Everything seems to b accurate as far as I can tell. I only ran it thru the EGR because I didn't want a toggle switch for the a.c. Either way they both work well so I guess it's preference.

I have another question. Guess I'll just post it here. Just wondering why in the HP Tuners Editor closed loop fuel table I have 5 boxes for each coolant temp that can be adjusted? On the vertical axis, not sure if it is x or y, it says "none" & the top axis says "coolant temp". If anybody knows please school me on this. Thanks.
