I am curious as to what this problem turns out to be. It looks like you are logging what you need, but I don't get eq error when I run it, and my logs definitely show eq error properly.

This goes back to why Sirius asked for a map sensor part number. The linear and offset numbers will be massively different between a 1 or 2 or 3 bar map. Even between different part numbers of 2 ...

You posted this in your other thread 2 weeks ago. People made some observations and asked follow up questions in an attempt to help, and you never responded. Starting a new same thread will not...

Good thing it does not run yet. The spark tables are going to be problematic. Not sure why the ls7 MAF on a setup that would never max out the original MAF. Not sure why the switch to 2bar sd and...

This is how my graph for maf eq error is setup, and when I view your log it works correctly.

Sounds like a cylinder (at least 1) on bank 1, which is driver's side, is not firing. The unburned air makes the o2 sensor read lean, which richens the rest of the cylinders, making things even...

Sounds like the first person to have a legitimate use case for a factory ls9 cam in an NA motor. Cheap, not much torque, and likes to rev. Paired with a factory truck intake that does NOT...

Your fuel injector data is set up for a return style fuel system, so if you are running a deadhead system that will eventually be a problem. I say eventually, because your VE and spark tables are...

Now you understand my comment in his other thread, lol.

You have to post the tune before anyone can check it for problems.

Narrowband fuel trims will always try to correct back to actual stoichiometric regardless of what number you put in or what fuel you use. They are uselessly inaccurate at any other A/F ratio. Or...

It needs to be tuned. Is there a question?

The fuel trims can't work until you fix the oxygen sensor problem.

If you are willing to switch to a 12587603 OS, you could have a 2 or 4bar VE, a boost spark adder table, pwm boost control for a MAC valve, spark cut rev limit and launch control, and a few other...

Most people here refuse to click random google drive links. You need to upload the tune to this site.

Try this. No guarantees.

That would be for the best, because I can guarantee that the person who did that to your tune file has no idea how to fix it. It really looks like they just took pieces of other running tunes and...

So.... That is a totally bullshit excuse for a half-assed tune. It is like someone who did not know what they are doing pulled tables from boosted, non boosted, SD, and MAF tunes and tossed them in...

The stock tune is your base tune. Modify as needed. There are plenty of guides on here to help you figure it out.

Engine diagnostics>airflow>maf fail frequency high=0. That disables your MAF. Then set your maf dtc list to mil on first error. Whether you uncheck ses enable to keep the light turned off is...

This is the sort of reason behind why I always carry a fire extinguisher in the car with me on new builds until I am sure everything is 100%. Even a small gas leak on the exhaust, or a frayed bit of...

I would go the easy route and tune out the MAF until I got it running good in SD. Then log dynamic airflow vs MAF hz and plug the resulting numbers into a new MAF table. This gets you a very close...

Since this is one of the google results when searching this topic, I will resurrect this thread with the fact that I found an Edelbrock efi fpr that says it will hold pressure for at least 20...

There are many ways to end up at the same place tuning. However, I have found it to be most accurate and efficient to tune areas where PE=1 using the fuel trims, and tune areas where PE is not =1...

And now for something completely different...
