The spreadsheet is for the second generation TBI PCM, 16168625, 16197427, 16156930, & 16196395.
Information to upgrade the 1227747 to the second generation TBI PCM is here: http://www.gearhead-efi.com/Fuel-Inj...out-Directions!

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.

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?
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?
