As mentioned, AFM is GEN IV thing, and are you really worried about 1/2 qt per 4000 miles?

Ok, excuse my igonrance, I was clearly misinterpretting the whole EQ ratio thing. To change the PCMs stoich value I got Engine>Fuel Control>General>Stoich AFR, I think I got it now.

I really...

OK, so the only time I want to touch the EQ ratio then is for my commanded PE. You are telling me there isn't enough error between E0 and E10 to make a drastic difference. I want to keep 1 for all...

Right, I understand that, the trims deviate because of variation in fuel from the set stoich point right? Hence if you are tuned for 14.13 E10, but what you filled up with is really E5 and has a...

Does this sound correct, or am I misunderstanding the function of some of the tables:
Set main AFR to 14.4
1. Tune VE and MAF in OL SD with WB as follows.
a. Set OL EQ ratio to 1 for...

Agreed, but why would you want to tune your VE and MAF to an AFR that you won't be running in CL? Also, did you give enough time for your LTFTs to settle? If your LTFTs are still off after you dial...

Is what I said correct?

Stoich for e10 is actually around 14.13 or so, so people use 14.3-14.4 as a median between 14.68 and 14.13 to allow for variation at the pump between fillups etc. The O2 sensors do vary in response...

Wouldn't you want to tune your VE and MAF to stoich for your fuel, with PE commanded to 1.27 (14.68/11.5 or so) for turbo applications. Then it was my understanding as well that your trims...

In order to cammand 14.4 AFR, I would have to set the OL & CL EQ Ratio table to 1.019 rather than 1 for columns 140-230? Then set the PE EQ table to 1.11 in order to command 12.95.

How does something along these lines sound?

I am going to set my commanded AFR as 14.4 (for variation of e10 and tank to tank variation. Median between 14.7 and 14.13), and 12.95 (lambda 1.11) for...

Thanks, that's the plan. I want to tune for 91 as well, as it is readily available around here. I haven't found an answer as to approximately how much timing advance for higher octane. I know on...

I have searched but to no avail. Does anyone have a How To for setting up an Innovate WB with HP Tuners, so that it can be set up as dual signal and send NB to the PCM, and WB to the HP software? ...

I am going to start tuning my 06 Sierra with the 5.3L L33 in a few weekends, and had a question regarding wideband tuning while running stock manifolds. I have read that you can force open loop, and...

Good point.

Thanks

That would be a better idea. I was also wondering, are there any benefits to HP Tuners vs. EFI Live?

How much is a one truck license, I don't quite understand how the credit system works.

Also, both of us are fairly new to this, but I am totally willing to learn. he bought it to tune his LS1...

A buddy of mine has all the HP Tuners stuff, and I really want to give it a shot on my truck. All I would have to do is buy a license.

What I am wondering, is what exactly can I gain, and would...
