Idle to full throttle help.

Zip the file.

Forum members will want to see your Config File downloaded from the ECU and a Datalog of this occurrence. Global Configuration Files (GCF) and Datalogs must be "zipped" (compressed zipped folder) in order to attach directly to a forum post ("Upload Attachments").
Overlay the datalog onto your Global Config File (GCF), and pay special attention to the center paragraph in blue print:

We need you to download your Config File from the Sniper. Use the Save As and rename the Config File as this will ensure we are seeing the actual Config File in Sniper memory. The Sniper does not actively maintain the tune on the SD card, so it must be downloaded.

If you have not corrected the always bad Sniper default Base Timing Table, you need to correct the low RPM low vacuum (high kPa) region. This can often create throttle issues. Review this article: https://www.efisystempro.com/efi-pro...timing-control

A new Sniper tune rarely does well with WOT stabs. The system will go into Open Loop, and since you probably do not have a well developed Base Fuel Table, the result can be poor operation. Slow steady throttle applications initially will help the system Learn and modify the Base Fuel Table. The full four barrels provide a lot of air for your engine, and in some cases too much air too quickly. If you do searches on poor operation when mashing the throttle you can also find some of the resolutions.

Once you zip and upload your Config File and your datalog we can overlay and see what's happening. Any excessive lean condition with heavy throttle application can cause engine damage, so adjust your testing methods until you have the system properly configured. No Learning occurs when the system is in Open Loop, so it's not going to Learn its way out of your problem area with WOT throttle applications.

Here's two datalogs and Config File car has been run a few hundred miles and Learn Table copied into Base Fuel Table and I've worked out my own Base Timing Table that's been working great. I guess I never did any WOT stabs while I was letting it Learn. I did last night go out and do about 15 WOT stabs and it seems to be getting a little bettter. I hope that's a sign that Learning is working?

Look at your Learn Table in the Sniper EFI software.

I Transfer Learning To Base every few weeks.

Probably the wrong way to fix it, but only thing I could think of to fix it, I made about 15 runs going from idle to wide open throttle, and then copied Learn file into the base file. Did this two times and now I have some improvement, but not perfect yet. I'm open for any help. Thanks.

The Learn Table is a modifier of the Base Fuel Table. These two tables actually function together as one, because the Learn Table values are directly applied to the Base Fuel Table. The Learn Table just indicates how much the Base Fuel Table has been altered (modified). The Base Fuel Table values don't change, unless you Transfer Learning To Base (which then allows you to blend the Fuel Graph so it's smooth). It's the Learn Table itself, that contains constantly changing values. When the Learn Table values stop making significant changes, the ECU is finished self-tuning. The purpose of the Learn Table is not to achieve similar values, high/low values (0% or 100%), or any value in particular. It's simply indicating the amount of tuning applied to the Base Fuel Table. Read this thread (LINK), that's what it's all about.

Thanks for the information. Can you advise of somthing I should try to change to help with issue? I wasn't sure if enrichment settings would help, so I didn't change anything since the car runs great except for WOT stab.
