Weird Throttle Plate Closing Under Load

[ptharris]

Hi guys

I have a weird condition in 4th gear say from 1500rpm to 3000rpm at WOT, whilst logging you can see the ETC (electronic throttle) opening then closing, opening closing etc. You can also feel it in car obviously

Only does it in 4th gear between 1500-3000rpm at WOT all other gears are good.

Torque management is disabled

2005 BA MKII XR6 Turbo

4 speed auto

STD car

Tune to 8 psi and full remap on dynapac dyno, using vcm suite

Any ideas, have log but cant attach it here for some reason

Still sounds like torque control to me....

+1, whats your max engine torque set at?

[ptharris]

I also believe its torque control

Max is set at 525, didnt touch that table. Tried logging engine deliverd torque with HPT VCM, but didnt log

Tuned today to 247kw on dynopac, I was very happy with results, stock was 203kw. Just looked at the dyno reading, Im hitting 600nm of torque at 2600rpm, dont know if this helps with that table

Didnt notice this till I road tested it

Hiddeous, I have emailed you my tune and log

Cheers

Mines set at 752 you could try that and see how it logges.

This table?

You only need to log your Torque Source, Fuel Source and Spark Source during the condition - and the answer will be right there in front of you.

Then simply adjust the RPM to use ETC for Torque Reduction table. I have no idea if this table exists in HPT Ford tuning, but that will be most if not all of your answer.

Yes that table does exist

[ptharris]

ETC Torq managment is set to all zeros

Torque Source, Fuel Source and Spark Source is not avaliable in HPT (that im aware of, maybe named different)

Ive logged it and its definitely throttle plate closing, then opening, then closing. So definitely torque reduction

No the section was under Trans then Torqe Management and the figure I gave was 752ftlb or in metric 1020Nm.
