What Pin at PCM for wideband to AC input?
#18
Thanks for the info. Buying just the LC1 is still cheaper than buying the LC1 plus and then trying to do 2 different data logs at the same time. This way, I can do everything in DM and not have to worry.

It is very nice however to have everything time synchronized in the same log to export to Microsoft Excel or playback in Datamaster. Otherwise all the transient throttle changes, and how they related to a/f, will be very difficult to relate to any other parameters that were changing (MAP, RPM, throttle position, BLM Cell). With just a standard a/f readout it is nearly impossible.
It's a simple formula change in Excel.

Not to mention the $100 savings from just buying the LC1. $100 isn't huge, but with gas prices the way they are, it's better than nothing. Again, thanks to everyone who participated in this thread.

Or you can use MSII ecu piggybacked on the stock PCM to drive the injectors and leave everything else the the stock ECU.
MSII can actually tune itself with a wideband wired to it. Just input the A/F ratio desired .. drive .. done.
Just have to use stock ECU for timing...

I dont know what its not working for me. I kinda gave up once the 90 degree days got here and I havent been driving it. once it cools down again ill be taking it out and trying to figure out what I did wrong. The method seems solid, the AC input is 5-volts and the wideband output is 5-volts. the guy on the impala forums seemed to get it to work.....

I scrolled through the thread and didn't see anyone post up this link.
This is what you need to read to get it running right.

I'm picking up my LC-1 on Thursday... and should have it installed next week. The wire to the PCM is probably the easiest part of it. I went through the steps to configure the Datamaster as well... and it worked... now I just need install the bung and get the kit wired up.

The wire you should use for feeding in the wideband signal is the A/C pressure signal, which is the red/blk one on the a/c pressure sensor connector, which goes to pin D12 on the PCM.
Hope that helps.
