I replaced my antique LC-1 with an LC-2 yesterday as a) EXT.AD1 and EXT.AD2 were always showing as 0v and b) LMWorks showed my AFR bouncing between 7 and 20 both at idle and off idle.

The LC-2 is...

Yes - O2 sensors are close to the back ends of LT headers, one on each side.

This is the stock 98 LS tune, except for stoich has been set to 14.12 and we've altered the MAFFREQ table.

As...

I don't really know how to define "sane"; that was what was confusing me a few posts back - the averages seem to range from about 51 (2800 rpm at 15kPa) to roughly 81 (2400 rpm at 90kPa)?

Stock...

I don't know if the matching of PIDs in a log to the slot# matters; I suppose they do since I shuffled the numbers around and you ain't seeing what I'm seeing... on my end I'm seeing DYNAIRTMP...

Ok - so this would replace the values I already have?

For example - 20kPa @ 1600 rpm would become 61.9 instead of the existing 49.67?

I don't know that this is right, I must have done something wrong in here - the values I'm seeing in the CALC.VE_Table after a somewhat long log range from about 55 to 82, and it seems more like they...

I don't have DYNAIRTMP_DMA to compare against to make sure that the values are comparable, but I'm guessing that I replace GM.DYNAIRTMP_DMA.C in the Calc.VE_Table calculated PID with this new...

Sanity: confirmed. Brown is connected to pin C. The settings are the factory defaults for Analog Out 2, with the exception that stoich is set to 14.1.

This is a 98 Trans Am. DYNAIRTMP_DMA doesn't...

Even if I "validate PIDs" before I start monitoring/logging, DYNAIRTMP_DMA isn't considered a "valid PID". Is that maybe something that isn't in 19980100? Is there an alterate PID I could use?

Okay - altered B3601 to reflect 14.12 for the E10 fuel that's all we can get here.

Reset the LC-1 to 2.5v on Analog 1 and 3.5 on Analog 2.

First log is with power on but engine off -- EFILive...

Yeah - when I use the right PIDs, I get values, how wierd!

I had already reverted the LC-1 voltage settings back to the defaults, so the log should actually be reflecting reality and not the...

That's awesome.... (laughing at myself). I'm on V1.

Will try with the correct PIDs. Stand by.

The result was not what I was expecting - the output voltages were pretty close to what was programmed, using the tiny screws in the 3-pin plug as the test points.

Are there any diagnostics to be...

Heater calibration - I think I did that by accident when I was first setting it up, but not intentionally or since. Think that might be the problem, given that LW works?

Please sanity-check me...

Quick response from the Innovate support folks -- redoing the free air cal fixed the bouncy, but not the lack of analog-out joy.

Sigh... still no joy (I had such high hopes).

Now LogWorks reports an AFR that bounces around all over the place -- even with power on/engine off -- so now I'm thoroughly confused. Reconnecting...

Thanks, Joe. Does pin D also get connected to vehicle ground, or just to the green wire?

After a reboot, LogWorks can successfully talk to the sensor. However, I still get no data through either the yellow or brown wires. I've tried with white both to pin D and floating, with no...

Thanks for all the help, Shawn and Joe.

Should there be anything done with the MAF frequencies less than 2500rpm? Even if I turn off the empty cell hiding, there's no data in that map for thost...

Thanks, Joe. The ground made some difference; the programmer now can find the WB.

However, neither EFILive nor LogWorks reads anything from it. EFILive just reports 0.0 and logworks reports "No...

New logs.

WB still not working right (separate thread for that), but I've got the NBs and MAFFREQ in this one.

8618

Black wires go through the button and LED (in parallel) to ground.
White is connected to input D.

Will add those PIDs to next log.

Okay, I installed my LC-1 per the instructions at http://www.innovatemotorsports.com/resources/efilive_lc1_tutorial.pdf :

Red wire going to a free Acc port in the fuse box
Yellow goes to pin C...

Here's where the stream of profanity comes in.

I've had a new LC-1 sitting in a box in my garage for five years now. Finally installed it in something... and it doesn't work. Used the...

Reckon that might explain the bogging/jerking I feel when I first start off from a dead stop. Figured it was just that I didn't quite remember how to drive a standard (been years, just had the car a...
