Ok. This is my first time that the wideband has read this far off at low rpm so it had me worried. Of course I haven't tuned nearly as many vehicles as alot of you guys. All of that makes sense. I'll...

2003 C5 6 Speed. Stock car, Cat delete, AEM 30-0300 wideband.
I tuned the MAF and VE tables separately with fuel trims off.

When I turn the FT back on the car pulls ~8-10% fuel out right away....

Bump. we got better injector data for what we have and that cleared alot of issues. Right not we can't get the adaptive idle to catch when we let off of the gas. I've tried using the follower, spark...

Current situation. Starts and idles good, beginning to take throttle better with every VE adjustment, I can not get it to catch the idle correctly after you rev it, and it hangs up pretty bad.
...

@5FDP .. The MAF isnt working because I have it unplugged. I ended up failing it and the car would idle and stay running.
The injectors are used stock LS3 injectors.

@serius.. I dont remember...

That made some difference but still does not run any longer.

I was told this pcm came from a dbc truck. I didn't even think to look at that.

Trying to help a friend tune his car.

77 Nova full swap. 6.0 block bored .060 over. BTR stage 3 cam, Fast Lsxr Intake manifold, Fast 102mm Throttle body(cable), Long tubes, Standalone Engine...

@Angordon3 is the owner of the truck, in case him listing the mods causes any confusion.

Little background, I've tuned several friend's LS based engines and I've had my own twin turbo Coyote Mustang.

This is my first Dodge that I am trying to tune, It is my...

Bump

Intermittently when I use my 2 step the car will go into injector cut.

Last night I made one attempt (2nd log) and it worked great. 30 minutes later I tried again and got an injector cut.(1st log)...

I went back a few revisions and the problem went away. Im working on adjusting the maf today and tomorrow. I must have made some change somewhere that it did not like, not real sure what it was.

...

Multiple spots in the log you can see when the car is dying that I am pushing the gas pedal, but getting no response. Tried to richer up the maf down low and made no difference.

I don't...

I believe it's about 3 inches.

If you look at the dying to hooters 3 log which is the latest. The maf doesn't look too far off.

Here are some more examples of the car dying. Made some tune changes to no avail.

Also thought that maybe my WOTBOX was having issues so I took it off and bypassed it, 3rd drive is with it...

2020 5.0 10r80 trans. On3 Low Mount turbos.

Fuel pump recently went out, Replaced it and had to redo my MAF transfer curve because the fuel pressure was dropping out before and I did not notice...

So I switch the "learn from BCM" to "use calibration" and just input the tire sizes? Do I have to do the change in the scanner also? I'll try it when I get home today.

2020 GT. Just swapped to 29.5 inch tall rear tires.

I see the editor and the scanner have options, I tried making the changes In the editor and my speedo did not change at all.

The scanner...

It absolutely makes a difference.
The stoich point of E60 11.28
the stoich of E75 is 10.45

Theres a pump here that pumps 83~86% every now and again.

If your tuned for 75% and pump 55% the car...

Is there any handheld device on the market that I can load my tunes onto so that I dont always have to carry my laptop?

I just started running pump E85 and would like to easily be able to switch...

The direct injectors have to be cycled even when not in use so that the tips don't overheat.

I tried turning off cylair anticipation and it deffinatly drove worse. I also turned off ltft.

In...

How much boost does a whipple start at? That seems like alot of timing on 91.

Ok I believe I found it. ENGINE>SPARK>ADVANCE>FUEL>LAMBDA The table is set to add 8 degrees of timing when the fuel is rich enough to make power. This forces the spark high enough to hit the cylinder...
