Anything going on that would lead the 02's to read incorrectly? AKA are you running the supplied manifolds and have exhaust on it at this point? I'm unfortunately not informed enough to make other...

I would hesitate to monkey too far with the tune in that case and look for a mechanical / setup issue, I would hate to see you compensating a huge amount in the tune for an issue like that and have...

(Yes, you would then save and write that to the ECU)

did you buy a kit like this: https://www.summitracing.com/parts/nal-19258004? And if so, are you running the supplied manifolds/cat pipes with...

working for me!

Ah, nice I will change that and do some logging. Thank you yet again for the guidance.

So I went for a drive yesterday and am noticing some KR in some places. I can easily force KR jumping into the throttle from cruise. The Flex Fuel Advance (logged in this scan) is very low or...

Now to clean up my wiring get it all together and go fill up with e85 and get going on the headers and catback.

Well, I guess I'm good!

Excellent. I see why people mis-seat/have issues getting the pin in there. Just grabbed 5 gallons of e85 and am off to toss a couple in and see what it says!

Okay so sensor in and I *think* wired properly. Getting that pin to sit properly was.. uh, fun. I added Fuel Composition Sensor to the scanner and it's reading 50hz (no ethanol) which is correct...

I assume he's pointing out that you're "good to go" as long as the car is CAN BUS compatible and not VPW, which is true, yes.

So are you tuning 2003-2005 Dodge Cummins 5.9L engines that you want to keep using the lock feature on? If so, you're good! If not, you've lost that feature.

Nice I think that provides ample (pun intended) options for power connection withing tracing a dedicated line back to the battery.

No doubt, that's super annoying. Best explanation I found: http://www.obdtester.com/obd2_protocols

mine is an 08 so it should be good to go as I understand it...

Just got mine, I like that everything but the power connection is pre-wired/terminated in plugs. Screw the sensor in, plug everything in with 12v power and off you go. Still need to find a spot for...

I don't know if I'd pull from the ODB2 port. I would suggest a switch letting you warm the car (and thus the o2 sensor) up prior to turning it on since I'm sure most of the pull is during heating the...

Is the power pigtail coming off the ODB2 connector? Meaning, you would hook sensor to extension to gauge and ODB2 to gauge and ODB2 to power?

I think I bought a day or so before you and mine isn't going to be here until the morning! Dang it!

Just an FYI For anyone following along I did submit this to Support about a week ago, got a ticket number back but no response. Not sure if I should expect one or not but hopefully they'll add them.

Sevinn- what volume did you come up with for the fuel rail if you don't mind me asking? That'd be about the volume I'm working with.

That is how I understood it after reading, thank you for confirming. Like you said, a tiny amount between the sensor and the injectors in my setup so I'll set that very low.

they appear to be compounding values, if the tool tips are to be believed. I assume this is post-sensor only because how else would the ECU know about the change

Delay Volume- [ECM] 3147 -...

Mike/Schpenxel - I too was eyeing up those values. Seems to me that that is the time/flow the ECU waits to move after the sensor detects a change, correct? We should be able to turn that way down...

Thanks Mike, This is basically how I understood it, and I understand "pointless to add" as "Maximum add before detonation" isn't "Maximum horsepower"

What is interesting to me is that in stock GM...
