Well it is together and ready to drop in. Any more inputs on the tune before I get her ready to fire? I'll probably be turning the key in the next three weeks if things go as planned. Thanks.
Your O2 sensor looks like it is only picking up one cylinder.
Some people might think it excessive, but I run both the stock and wideband O2 sensors in a short tube after each header.
This is the time to plan the location and install the wideband sensor(s).
Nice looking engine. Where did you find the black valve covers? They look great.

It's after the merge in the collector but I hear what you are saying and am doing just that. I moved to off-road pipes with two bungs. So the collector will feed the factory narrow band sensor. The first bung will feed the Innovate wide band. The last bung will be plugged but available for dyno tuning sensor.
The valve covers are factory. I just did a little prep work and then painted them with wrinkle black Duplicolor. Coil brackets also factory and painted with VHT victory red. Very happy with the results for little money. Did have to spring for tall gaskets to clear the Yella Terra rockers but they look and work fine.
Just a quick bump for anyone willing to comment on the tune. Will start putting the engine in this weekend. Probably firing it up next weekend. Thanks for the help.
Well she fired right up. Runs rough though. Had good oil pressure. Which is the first thing I checked. No leaks. Data log AFR reads differently than my Innovate Gauges so not sure if that is an air leak in the exhaust or something else. I was in the high 14s for AFR when holding the rpm at about 1500 according to the wideband. Going to load the scan tomorrow for comment if anyone is interested in popping in. One step closer. Thanks.
Doesn't your logged AFR come from the Innovate wideband controller?
How different is the log and the gauge? I presume less than 10%.
I had a similar problem:
My AEM gauges were displaying about 5% different from the logging. Assuming the gauge was correct and the 0-5V output a bit off, I therefore made a custom input to the HPT scanner and used an offset and divider to make them match at both ends of the AFR range. IIRC instead of a typical offset of "10" and divider of 0.5, I ended up with an offset of 9.8 and divider of 0.51 for one gauge and 0.52 for the other gauge.
To verify that the wideband sensor/gauge/logging is accurate, also log the stock narrowband O2 voltages. When those read about 0.500 volts, the corresponding wideband should read about 14.7 (lambda 1.0). When they do, you can be confident that the wideband is accurate (at least near lambda 1.0).

I hope this all makes sense.
I didn't connect my gauges to the Flash Scan yet. Still monkeying with the cable, null modem, DB9, flux capacitor stuff (yeah its foreign to me) So I am tracking on what you are saying with respect to comparing inputs. I'll have to play with it some over the coming weeks. In the mean time maybe I'll run an EFI Live scan from the OBD port and log the widebands oil pressure/temp separately using Innovates scan software. Thanks for the input.
Here's the startup scan. I cranked the engine with the accelerator to the floor for about 10 seconds to build a little oil pressure then fired it up. Started immediately and ran ROUGH. Took the rpms up to around 1500 and kept it in that area for about 15 minutes while I checked for leaks, monitored pressure/temperatures, topped off fluids, etc. Took the coolant up to about 175. Oil pressure was solid 70 psi and the oil really never came up to temp enough to see it come down.
Anyhow, scan attached if anyone's interested in critiquing it. I'd like to try and dial the tune in a bit more to get it on the road for some break in time before hitting a chassis dyno for a tune. Thanks.

Also log these pids: SAE.LAMBDA, GM.ETCTP, GM.HO2S11, GM.HO2S21.
Drop these pids: GM.TP, CALC.VE.
Which wideband do you have...?
Is it connected to your FSV2 using analog or serial comms...?
Depending on your answer, you also need to log some wideband pids.

Hey joecar! It lives in part do to help from forum members (you included) so THANKS!
Copy on the PIDS. I got a little excited to start it and realized I had not changed them appropriately. I will run another scan tomorrow with the changes.
I have the Innovate Motorsports DLG-1/LC-2 wideband.
It is NOT currently connected to the FSV2. Still trying to figure out the serial/null modem/DB9 setup. Not my strongest suit so this run was just monitoring the gauges. I'm pretty sure I know how to make the adjustments for wideband logging but my understanding is I can only do one bank. Sound correct?

Thanks again.
for example, you could do this (LC-1 shown for example): see 1st pic.
or you can fabricate a cable like this (eliminating the DB9 connectors)(see how Rx/Tx swap): see 2nd pic.
If you can talk to your LC-2 from your PC (using LM Programmer or LogWorks), then you need another cable like this, replace the end with an RJ12 and swap the Rx/Tx signals (FSV2 can read from the LC-2 and it can tell it to calibrate, i.e. bidir).

No worries, take your time.
When you go to tune this, you will have to drop another pid or two to get the sampling rate up high (24 pid channels samples at about 40 frames/second).
The wideband goes in one bank, but the VE/MAF tables operate on both banks. If you are concerned, then FSV2 can read serial comms data from 2 Innovate widebands daisy chained together... but typically this is not necessary, people place the wideband in one bank and tune from it, and then swap it to the other bank and do a sanity check.
Daisy chained. So I was hoping I could read both banks from the connection to the DLG-1. It's supposed to work with their LogWorks software but not sure if it will work with the FSV2. I'll review your posts regarding the connection this evening.
I just look at the user manual for the DLG-1... it looks like it connects to an LSU sensor... i.e. the DLG-1 is a whole wideband with a display on it...
we'll have to investigate if FSV2 will see both the LC-1 and the DLG-1.

and you would then also connect the OUT port of the DLG-1 to the RJ12 port on FSV2... i.e. FSV2 should be able to read both
