PostSubject: torque management, KR recovery rate, etc?   Sun Dec 13, 2009 12:11 am

So Devin and I have finally gotten my tune in shape for the moment. i have all the motor mods i want (for the moment) so except for weather change i should be all set.
Here is where i am at so far with the Powrtuner:
My LTFT's are within +/-5 all the time and always lock in at 0 for TP above 28%.
O2 readings show it locks in in the 920's (a little low for my taste, but it was cold out)
No KR unless it is really cold out, then i see a max of like 3* at shift points.
Ran the "shazam" program and it helped out my timing too.

So my question is what else can i change? Keep in mind this is for a 96 so most transmission settings (like line pressure) are not adjustable.
I have made some changes to some of the TQ management setting, but there are a few i dont know about.

Under supercharger/boost control/traction mode controlled by boost it shows a factory setting of 1%, devins zzp tune has it set at 100%. mine is at 6.99%, but i dont know what this does.
Also what is everyone setting their KR recovery rates at? i'd like to be able to recover lost timing as quick as possible, but is there any danger to doing this?
Lastly, the closed loop idle spark correction is still all set to stock, but devins is different from zzp. can i adjust how much idle rpm there is at idle with this? mine seems to fluctuate a good bit leading to a rougher than brand new feel.

Thanks for any explanations on these.
Matthew

Did you get your LTFTs in line with a MAF or VE tune?

I have not changed from stock any of the three settings you mention. Personally I do NOT want a "fast" recovery rate on KR. It recovers pretty quickly IMO and I'd rather not push my luck.

The more time you spend with the tuner, the more settings you can learn to tweak manually. I started out using the blattner's shazam tool but have decided I prefer to adjust my tables manually now. There are some risks involved in making global changes to your timing.

How high have you been able to take the fuel trim tune before PE sets in? I can get up to about 40% throttle in non-PE mode now (the Gen V blower made a big difference there) before I see any KR.

both. We did pretty extensive VE tuning before working on the MAF.

IIRC the stock TP% was 40% for PE to engage. i reduced that to 28% when i got the northstar b/c thats what the tuning guide told me to do lol should i have been going the other way with the %?

You want to get the PE setting as high as you can without encountering KR or boost... Once you start engaging boost, it's generally time to go to PE mode, if you can watch your MAP you'll know at what TP% you hit boost... that's where you want to start your PE. You can go a little bit higher, but not much. Sorry I have forgotten where this is on my car. I'll review next time I have a chance but it will probably be a few days.

Under Supercharger/Boost Control/... I have two parameters similar to the one you mention:

Traction Mode Boost Control by Torque - (stock 100%, mine 100%)

Traction Mode Boost Control Enable - (stock 4, mine 7 [came with DHP 1.5 BIN])

My KR Recovery Rates are 3 times quicker than stock (stock is .79 Deg/Sec, mine is 3 Deg/Sec). I don't see how this is harmful, because under sustained KR, it will not recover at all. After the "coast is clear", I want my timing back asap.

Closed Loop Idle Spark Correction is a mystery to me. Mine different (lower) than stock, as they came from DHP 1.5 BIN. They seem random to me, but I'm sure there's some order to it.

thanks for the info guys. i'll have to make a few adjustments when i get time and see if anything changes.
My hopes were to be able to reduce the amount of traction contol when it is enabled. kinda like in video games you can set traction from 1-10 to adjust how much it activates.
I feel like our TC systems pull timing, apply brakes, and reduce boost way too much when even a little wheel spin is detected.

That's a whole different set of parameters on my '98. What options does the '96 have under torque management?

Yes, I have those too. I can give you some decent things to change there. I don't have my computer with my PT here, if nobody else beats me to it, I'll post some up later.

most of those setting have been adjusted already, but i'd like to compare to yours too.

Can I get some help with torque management, please?
For all yall with stock trans 98+, what did you do with your settings? Thank you

Here's what I am looking at. All stock settings. Not sure how to proceed.

The Performance set you can ignore. That's preset into the PCM for Regals and GPs with the Performance Shift button. It's turned off by default, but the table is still there.

I have my entire Torque Reduction table set to "0". It does exactly what the Title says, takes away Torque at all of those shift points. I like my Torque....

so for the normal table; you think i can just start reducing it little by little and testing it?

This table is to protect our transmission for shredding themselves, right? So just a little off shouldnt hurt anything?

0 sounds crazy, but you have that built trans and you crrrrrazzzzyy razz

I think it's more for the Buick comfort factor than anything else. Even if you set that table to "0", the trans can still be mush if you don't change the shift time and line pressures. You probably wouldn't even notice it.

What's everyone running for their torque abuse speed/RPM/time/throttle enable tables?
