I don't have a P/N limit anywhere? Am I just blind? 08 Z06. Working on no lift to shift.

Thank you very much sir!

Anyone have a file for a 2008 Z06?

Good eye. I wasn't looking at the voltages. I disabled the MAF and the voltages were in the 890-900 range, along with the KR going away, and the fuel trims falling in line. I believe the MAF is...

Here's a log that's showing the LTFT's and KR. It looks like as soon as the vehicle enters PE, and the fuel trims stop adding fuel, the Kr comes in. So it seems like this is a fueling issue of some...

Stock 2006 C6 LS2. 60k Miles.

Stock timing/Tune.

Seeing 10 degrees of KR at WOT. Is this false, real? Running 93 octane. Hasn't checked plugs yet, I'm guessing that's the next logical...

Got it! Thank you, it's been awhile since I've dabbled in it.

What I should say is the table is there, but the entire axis is just 14.6, there is no 9. So there's no Air-Fuel ratio for ethenal in that 21320 - Flex Fuel Ethanol % Vs AFR table.

I shot that...

Any idea on how to fix this, or what I can do?

Interestingly enough this table isn't in the 15, or 16 mustang file either and people appear to be having success with them. Am I missing something?

I'm also noticing on my 2017 the ECM 21320 - Flex Fuel Ehtanol % vs. AFR is all 14.6 on the left, on the F150 it's 9.0 and 14.6 on the bottom. Is this causing an issue?

I have a 2017 and enabled everything and copied the tables from the f150, but my alcohol percentage never changes in the scanner. Are there any issues, or tables missing for the 2017?

I'm curious if there is some kind of switch or something missing from the coyote's PCM vs. the F150's... Like to enable the "virtual sensor"... I see there's a bunch of alcohol tables that are and...

Yes of course. The WOT lamda is fairly rich, and the timing table isn't aggressive at all. If you're running 91/93 octane instead of 87 you can pickup a fair amount of power. I ran E85 on both of...

Do new fords 2011+ use a virtual or physical flex fuel sensor? Did the 05-10 use a virtual or physical? Does anyone have any of these table values, or know if filling them in/enabling them would...

Yes, I'm in pure MAF. I don't think I have an vaccuum leaks, I gave the hoses a once over. Any other ideas?

2009 G8 GT, Headers, and Vararam, only mods. Running E85, or gasoline I have the same problem. At idle, like the 2 idle maf cells the car his the car just ADDS fuel. I've added 20-30% in the idle...

Yeah, but think about this, if you don't' change the command AFR from gasoline to E85, you're going to be MISSINg 33% of the fuel the system needs to get to stoich, and your fuel trims are going to...

The stoich AFR isn't the same for E85 vs. gasoline. Therefore your commanded AFR has to change, or your fuel trims and what not will be WAY out of wack and line, and you'll eventually throw a rich...

They're talking about this table:

Stoich AFR Table: This table is used for vehicles with the dual fuel option (alcohol)
The base stoichiometric fuel/air rate is determined by a returned value...

I'm assuming this didn't work on your TBSS?

Interesting info:

Flex Fuel Option

{B0178} Flex Fuel Option Yes
{B0184} Flex Fuel Sensor Type Actual Sensor
{B0185} Flex Fuel Default Percentage 50 %
{B0186} Flex Fuel Sensor...

Anymore info on this, and exactly what it does?

Doesn't look overly rich/lean anywhere to me. The LTFT's are pretty funky though, and are adding 7% of fuel downlog, and taking away 5% or so up top, have you done any VE/Maf tuning? I'm not sure...

BTW be careful running a E85/93 mix, as it will run quite lean. E85 requires 30% more fuel than 93, so you're probably killing your fuel trims to get you where you need to be, hence the lean code.

Thanks for the quick response. I've already adjusted for the additional fuel. Just needed to change the stoich value to E70's stoich instead of unleaded. The fueling is all good, and all trims are...
