Will a 16197427 out of a S-10 or V-6 application work? Or do I need to get the V-8 one?

The basic difference between the V6 16197427 vs. V8 16197427 is the Memcal, the blue thing in the pic below. The Memcal has three functions, PROM Chip, Knock Filter, and Limp Home Mode. If possible, I would try find a 16197427 with a Memcal for the same size engine I am installing the 16197427 PCM to operate.Originally Posted by Tbrendal

Hi Dave,
I'd like to try and use your Wideband spreadsheet but I'm having a problem. I'm guessing your spreadsheet is designed to take the original "WBO2 AFR" .csv info from the "Data Log" but I'm using an Inovate MTX-L WB AFR gauge hooked up to my Autoprom, while I've managed to set up a history table showing my Wideband AFR's I haven't managed to get that information into the "Data Log" for export to your spreadsheet.
I'm not using the hack where the Wideband O2 sensor output is supplied to the PCM via re-tasked EGR output and I'm guessing that's thats what the Data Log is expecting.
I'm not sure how to get my MTX-L WB AFR outputs into the Data log in the "WBO2 AFR" location so that your spreadsheet can then use the data or is there another way to get the info into your spreadsheet?
The use of the Autoprom is not required to get the WBO2 information into the data log. The 0v ~ 5v output from the MTX-L has to be wired directly into the computer, pin B16. See attached screen shot.
The MTX-L will need to be re-programmed for 0v = 10 AFR / 5v = 20 AFR

Hi Dave,
So unless I want to disable my EGR there is no other way to use your spreadsheet?
Can you post a .csv file with the Autoprom data? I might be able make changes to the spreadsheet allowing the Autoprom WBO2 data.

Hi Dave,
That would be great if you could.
I've attached the full .csv file from a logged run, the "MTX-L WB AFR" output is in column "EV".
Hopefully you can successfully unzip the compressed .csv file.
Im gonna try this with my lc-2
Hi Dave, I'm wondering why are you filtering only closed loop data for WBO2 corrections? It doesn't make sense to me, as BLMs will change WB readout in CL.
I use WBO2 data from open loop AE and PE when the computer locks the BLM's to 128. CL WBO2 data will validate the corrections to the VE tables for rich or lean BLM's. A VE table causing rich or lean BLM's will also cause rich or lean WBO2 data in CL. BLM corrections have a limited ability to correct for rich or lean conditions. I've tuned several vehicles with AFR's. The WBO2 tuned vehicles run better, have fewer emissions, and achieve better MPG using CL WBO2 data.

HI Dave W, I've seen in many of your posts you're referring to screen shots, which I cannot see on my viewer. Any suggestions on how to enable that?
I am logged in.
I have set my "general settings" to show images.
Earlier this year there was a issue with some files / attachments missing after an update. What thread and post do you need the screen shots for? It's likely I need to report the missing screen shots.

Thanks Dave W.
It's this thread, your posts, #5 and #15.
I'm interested in your use of the ECM as a way to use WBO2, as I'm about to purchase either a BURN2 and Ostrich 2.0, or a APU1. I'm leaning towards the lower cost BURN + Ostrich, especially if I can use the ECM for a future WBO2 sensor. Thank you for sharing your tools an expertise on this forum!
