4522.xdl First couple starts were good and it wasn't so bad, but after 10 or so it has the problem between 15 and 20 RPMs. It's like the PCM is making it worse every time its driven.

The tune is acceptable, not optimal.

There was an Injector Spike in the data log, not sure the spike is real or a glitch.

I researched what might cause that injector spike and pulled the injectors and changed the screens plus I checked the connection at the knock sensor, which was questionable, so I changed the connector. Every time I load a bin to the ostrich, I first disconnect batt neg wait a couple minutes, load bin then reconnect batt. So, I loaded the 2022 update bin and It worked great for the first drive but started hesitating between 1500 and 2000 rpms on the second and got worse on every drive. I hit the emulator button and changed linear egr to not set and no change. set- backpressure egr and the idle got a lot more steady. set- 32 egr and the idle smoothed out. I've been on several drives and its not digressing and it's running well. Now that I know this is happening, I will reset the pcm and load the bin before I record a log. might get good data before the wb02 perimeters start making it run bad. I'll post a log this evening for you to look at. Thanks dave w. Add it to the bill

Using WBO2 requires very specific .bin parameters for the AFR's to be included into the data log. The WBO2 hack repurposes the Linear EGR 0V ~ 5V for WBO2 data. Factory chips are either Linear EGR or Backpressure EGR. Mixing Linear EGR parameters with Backpressure EGR parameters is not a good plan.

Typically, when I'm using an Ostrich 2.0, I leave the vehicle battery connected when I update the Ostrich 2.0 with a new .bin file. Typically I upload a new .bin file into the Ostrich 2.0 with the ignition switch in the "OFF" position.

I changed my injectors from 61lb to the Rochester 17084327 68lb HO 350 injectors from motorman. I'm tuning for 300HP so I set FP at 19.5 and was going lean. I logged data and used the wbo2 worksheet and made changes to the open throttle VE table and it ran better but I have hours of work to do before I understanding how to use the wbo2 program. What does special paste mean? Does it mean to only populate the cells that you are going to change in the VE and data input area of the open throttle tap section in the spreadsheet? dave w I've got more ammo for the hired gun.Guess Work_2022-Update_02.bin414.xdl

It's a good plan to change the name of .bin files with every update. For example "Guess Work_2022 Update_02.bin" to "Guess Work_2022 Update_03.bin" after an update.

I posted an update yesterday, then realized "Guess Work_2022 Update_02.bin" had updates from the file posted earlier in this thread, which caused erroneous changes.

Different injectors and different fuel pressures can affect injector parameters and injector offsets.

The attached .bin has more tuning Guess Work.

I agree, I like to save as with a new name BEFORE I make any changes, so the generated log reflects the changes made.
I personally like to say briefly what I changed in the file name, such as" VE 3 ol "
