I would use my injector data (minus the flow rate). It's basically stock 2001 z06 data with slightly modified pulsewidths. I've tuned 5 sets of different size injectors with that same data. You...

You're welcome , good luck man.
I'm at a loss at this point. Sorry
Ahhhh now we're talking. You've converted to DBW, that changes things a bit. Torque management -> General ETC limits -> ETC TPS MAX -> Set all to 100 ETC INJECTOR DISABLE -> All 255's ...
What make/model/year truck was the PCM from?
Here's a stock 2003 Silverado 6.0L tune ... load it as a compare and copy the all the Cranking Fuel values over to your tune.. There are some big differences there. Also take the Cranking VE...
Holy poop on a stick! In your log I'm seeing 40 pulsewidth while cranking , and that's with the settings I gave you I took 50% out of your ve. Unbelievable. Cranking PW should be 3 or 4, if I'm...
Ok,put your IFR back at all 52's and change the tables in the spreadsheet I've attached. You should be able to copy and paste everything:
I still think your wideband has it's head up it's ass, ...
You still need less VE , can you post your latest 2bar tune and I'll revise it for you. See how your injector pulsewidth skyrockets as MAP increases even at low rpm? PW should be around 2 during...
Setting it to 60 ifr will decrease total fueling, and the injectors are likely rated to 60lb/hr at 43psi fuel pressure, so its gonna be the correct setting anyways
Ok , set your IFR to 60 across the board. Then copy these values from my tune (2007 lq9) that I've posted below: Under Fuel -> General: Copy the Injector offset , short pulse adder , default...
18-20% throttle at cranking/idle is not unreasonable. Your wideband might be ok , its just reading max rich which makes sense given how your plugs look. So the problem is probably your injectors...
Is your stoich afr set to 14.6-14.7? And o2 sensors are plugged in correctly ? I think its possible mix up pre cat and post cat o2s. your wideband might be right. Log your commanded afr
Mine is PLX wideband , too... but it's hooked up a little differently. I don't use the cigarette lighter , I wired it into a switched 12v source in the passenger footwell. I forget exactly but I...
You set it up like this , right? :
48718
I would take a stock lq9 tune , flash it in and go from there. If you get your wideband working , it will be easier to diagnose. It's probably just not configured properly in the scanner. What...
Your maf and your wideband aren't working. The values aren't changing at all in your log.... They should at least be bouncing around a bit
