The coast down spark is stock. Is that what you meant?
I went out to test it, and now DFCO basically doesn't turn on. It turns on after the pull I did, but then after I get on the gas at 11:00 and...

I put the rpm limits back to stock and changed what you suggested. DFCO is still going on/off.
It happens toward the end of the log.

I have played with the settings for a...
So I put that table back to stock and nothing changed. I also made sure every DCFO parameter should be triggering DFCO and it is but the issue is still there.
When DFCO enables at lower speeds...
Would I correct it by putting stock values in the "coastdown" under "idle spark advance"? I noticed those values are reduced compared to a stock ctsv file
I never asked for a burble tune on the...
I have noticed that the spark timing drops from 12-13 to 5 then goes back up and it makes the car lunge forward slightly when the converter is locked.
When the converter is unlocked the rpms will...
The car is a 2013 ctsv, stage 4 6l90 from Circle D, and a Circle D 3000 stall triple disk converter.
I finished breaking in the trans and I made some changes to the converter based on information I...
So my trans builder suggested I put a stock trans tune on the car and try it out. I did and it's still slipping.
The noise has progressively gotten worse as well so looks like something is really...
Yeah, I feel like the trans is probably going to have to come out and get torn apart.
I'll give that file a try soon and let you know how it goes.
I did another test and 4-5 is still slipping.
2-3 3-4 are perfect but 4-5 is just not having it. Here's the log 124880
I also logged the PCS pressure when it was making that noise and during the...
I haven't tested it yet. I'm going to drive it for a little longer just to make sure the trans has enough time to learn.
Also weeding out the issue of the fluid level possibly being the problem.
...
My trans has a modified valve body with the sonax parts from circle d. Wouldn't that affect overall line pressure and give a different reading than stock specs?
I tried to flash the tune you posted and it told me I don't have the credits to flash it, so I just flashed the "Tune (12)" file for the trans, did a write entire and reset/preset adapts. Only thing...
Ok the reason I ask is because when I had the engine tune corrected the tourqe model was changed and the maf calibration was fixed. So ill stick with what I have on the engine section because that...
Sounds good.
There has also been a frequent whining noise (kinda sounds like a dying power steering pump) in 1st gear when I turn the car on and give it gas. If I let it move while idling for like a...
Yeah after the rebuild the drive mode position sensor went bad so I did a full flush and fill a little over a month ago (barely drove the car because it sat for a month after). I did install a trans...
Not that long. The car was down for about a month and then it randomly started to happen about a week ago. Before that the shifts were mint. It's ironic 3-4 was bad now its good, 4-5 was good now 4-5...
Yeah still doing the same thing.124699
Here is the log Also if the shift pressure was increased shouldn't oncoming volume be increased? 124694
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.
Here's a log I just did. 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.
I tried the tune out today its great.
How can I fix the converter slipping alot for the 4-5 shift?
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...
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?
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?
Here's the tune. 124441
