Lately, I've been getting a 4-5 flair only at full throttle. I think it could be because of the converter but I'm not sure. Here is the log Attachment 124416

Yep, genuine slip. Reported torque is low. Also needs more shift pressure. Then an adapt reset / preset.
Just as concerning, did you notice your O2 switching lean half way through 3rd gear?
flare
Is reported torque being low bad?
How much should I increase the shift pressure?
I just looked at 2 previous logs and it shows 4-5 shift tcc pressure drops to 92psi, and another it drops to 94psi. Compared to this log it drops to 79psi. This log a lot sees a lot more TCC slip max of 101.9 vs 19.4 and 13.4. Should I raise the desired pressure to fix it?
Yeah, #2 spark plug shows lean so I'm getting the engine tune checked soon.
Post up your tune. I'll adjust it for you.
Here's the tune. Attachment 124441
You will need to adapt reset / preset
Thank you, I'll give it a try once the lean issue is gone.
I see just the shift pressures were increased. Will the increase of shift pressure prevent the converter from slipping too?
More than just the shift pressure was done. Converter not touched.
Ok I see I didn't look in the engine section. I sort of understand the changes in the tourqe model, but what is the purpose of the changes in the tourqe management area?
? Didn't change anything there cuz.
Here is the compare log from the changes you made to his tune.
Am I reading this wrong, or are there changes to the 'Engine'?
Thanks,

Yeah I see this. Last night I opened the 2 files up and some stuff was changed in engine TM and this morning I checked again and nothing is changed. Ill look again because I looked at the files on my desktop, then on my laptop its fine. Weird lmao.

This may depend on what software version that you are using, and what software version the file was saved with.
That's great!

I tried the tune out today its great.
How can I fix the converter slipping alot for the 4-5 shift?
Show me a good log please. Sometimes there is nothing you can do, and it may also be a bit of noisey data too. I'll have a look.
Here's a log I just did. Attachment 124669
The first message in this thread has another log you can check out.
I also know its supposed to slip but the rpms flare up a noticeable amount.
Still a slight flare at the end of the 4-5. Have bumped up the 4-5 shift pressure a little more.
Torque converter. I have put in some experimental settings. If you are able to do another 3-4, 4-5 run like you just did I'd be keen to see if there has been an improvement. Would like to see the log ASAP just to make sure its healthy. Basically the jist is it should apply full pump pressure to the converter.
Did you mean to attach a tune? Because I don't see anything.
- Ok got it I'm gonna drive it for a little so it relearns and I should have a log up in a little.
