This is my point. If you enable TCS in the tune, but try to turn it off with the TCS switch, it seems to remain active. I only noticed this after applying the two patches. Removing "Clunk Control" and "Throttle Tip In" does help a little, but I still get some hessitation on quick changes. I've tried adjusting CFCO settings and this had a small effect, but not enough. I think I need some more testing to see if I can work out the exact conditions when it occurs.

Can you please confirm those table numbers?Originally Posted by dynarex
B8034 = Estimated MAP
B7902 = Low Baro threshold for VVT control

I no longer monitor the forum, please either post your question or create a support ticket.
The table shown in that thread is related to Brake Torque Managment, whats that?
Standing still, put foot on brake, floor accell pedal. On the Holdens if you turn off the TCS then it ignores that 'feature' anyway. It should only be active with TCS on.

Ross mine started this when I applied the patch as well. I can't, but maybe one of you needs to try and load a stock unpatched file back into the vehicle and see if it still has the hesitation. I didn't have this problem when the car was unpatched.
I don't see any reason for this table to have any impact on the problem that we are seeing. Like you said, its just used when braking the vehicle.
tables-
Engine Operation.Airflow.General
{B8034} Estimated MAP Maximum, was out of range when loaded.
Engine Operation.Camshaft Phasing
{B7902} Low Baro Threshold, was out of range when loaded.
{B7903} Med Baro Threshold, was out of range when loaded.
{B7904} High Baro Threshold, was out of range when loaded.
this is what i get at every opening-if i try to adjust the truck will not run past 20% throttle-tcs/abs/reduced engine power and every other warning comes on

This is th point I was trying to make. Even when I switch off the TCS via the TCS switch, I get the hesitation on a WOT change. Disabling all TCS settings ( activation RPM set to 8000 ) seems to make the hesitation go away.
I'll have a go at this. It's an 11min reflash to remove the patches so I'll see when I can get it done. I'm almost certain that removing the patches restores the full functionality of the TCS switch, but I'll also need to plugg the MAF back in.......

Ok, I had to drop one of my daughters friends off home this evening so tried a quick test. I had the following settings and it was shifting fine, though the TCS switch was pretty useless....
B0515 and B0517 set to yes.
All other TR yes/no options were set to no.
B2501 and B2502, maximum and minimum engine torque were set to 1000
The rest of the settings are pretty much stock.
Tomorrow I'll try setting the torque settings to something more "reasonable"...
My problem wasn't on gear changes, this is a manual car, the problem was it was activating spark retard traction control as a CONSTANT speed say 45km at 1800rpm in 3rd, lightly press down the throttle and it spark cut even harder. Once I turned that setting from 100's to zero's which deactivated TCS completely the problem stopped and the car drove normally

Hey Swingtan, any luck with the TTC issues yet, has any one else had this problem with spark retard happening at a constant speed caused by the TTC system?
