LC-1 install problems

[BowlingSS]

Worked like a charm.... Everything in there looks good to go.
Thanks Bud!

Maybe I am doing something wrong, But When I started tuning the PCM was commanding 14.7 to 13.1 the wbo2 read 10.6 for both. So I adjusted the VE table by the ben factor and set the EQ ratio to command 13.1, and now I am at 7.68?!?! WTF. Decreasing the VE table reduces fuel right?


EDIT: I just set the car back to be able to go into closed loop and where it was commanding 13.61 I would see that for the first 20 secs of my log, then as the pcm started to lean things out and gradually go to a AFR of 14.7 the wbo2 read 10.1. Anyone have any ideas?

I would try and re-cal the LC-1.

YEAH, sounds like something still isn't quite right.

Which output from the LC-1 are you using? By default, output 1 is a NB and output 2 is WB.

I thought I had the right pid but i didnt... I was logging External Analog Voltage 1 which I have hooked up to the LC-1's analog out 1. So I was logging the wrong one. Here I was thinking that it was that much off because I have the LC-1 behind the pass side cat. Thanks TAQuickness, why is it that we always overlook the simplest solution? I'll do some more logging tomorrow and let you all know how it goes.

That did it!

Now it is actually working. THe only thing that I have noticed is when the ben is say .8 and I adjust the ve table by that, the next time I would log the ben would be 1.2. So I increased the decimal place to 6 and that helped a lot. THe car seems happier running at 13.0 at idle as opposed to 17.6 Thanks for all of your help guys, I really appreciate it! I cant wait to do some more logging!

No problem.

It's funny you asked that questions because I had the that conversation with a process control engineer yesterday!

Sometimes all you need is a fresh set of eyes.
