new beta with E38/E67/T43 torque management additions

[carneb]

Neither actually.

What happened was that I noticed a while back there was a PID for it in the scanner but it never shows any values other than zero, so I just assumed it was a feature that you were in the process of implementing but hadn’t fully finished.

I did however just discover that not being able to turn it off is wreaking havoc on the lockup clutches of aftermarket torque converters since the clutch material they use is not designed to withstand the constant on-off that results from PWM.

Can you consider this my official request or do I need to start another thread for it?

Thanks,
Christopher

I didn't think that the TCC solenoid used PWM at all? Not according to this anyway:

The Torque Converter Clutch (TCC) PC Solenoid is a "normally-low", electronic pressure regulator used to control the apply and release of the torque converter clutch based on current flow through its coil windings. The TCC PC solenoid regulates actuator feed limit fluid pressure to the TCC regulator valve, located in the lower valve body, and provides a signal
pressure to shift the TCC control valve, located in the pump, to the apply position. When the TCM determines to apply the TCC, the TCC PC solenoid is commanded to specific pressures, dependent on vehicle operating conditions,
resulting in a smooth apply or release of the TCC. The solenoid's ability to "Ramp" the TCC apply and release pressures result in a smoother TCC operation. When vehicle operating conditions are appropriate to apply the TCC, the TCM increases current flow to allow the TCC PC solenoid to increase PCS TCC fluid pressure, to move the TCC control valve to the apply
position, and move the TCC regulator valve to the regulating position to regulate fluid pressure porportional to solenoid pressure. Release pressure is directed to exhaust, and regulated apply pressure is directed to the apply side of the converter clutch plate/damper assembly. The TCM then increases the pressure to control a slippage of 20-80 RPM between the clutch plate and converter cover. This "Ramping" procedure provides improved dampening of engine vibrations and allows the TCC to apply at low engine speeds in 2nd, 3rd, 4th,5th and 6th gear.

Maybe we need something to tell the TCM that we don't want it to give 20-80rpm of slip when locked up?

But according to what I've been told, it's the "ramping procedure" that is what's causing the converter to lock and unlock repeatedly.

Or am I missing something here?

Can someone translate what 38/E67/T43 is?

[Bill@HPTuners]

E38 pcm in many late model trucks & vettes

E67 pcm in many late model 4 cyl, 5 cyl, 6 cyl, & 8 cyl vehicles from solstice to ZR1 to trailblazer SS

T43 TCM in many late model A6 equipped vehicles, TCM is located IN the transmission.

Ah, thanks for the clairification Bill. Didn't know if this was something that impacted me.

[CRASHNBURN]

Anything new for the LBZ diesels in this beta????

[bluessv]

With the new TQ Management tables relating to Tip-In, Flare and Limit.

Can someone please explain what these 3 are? And what's the difference between the different settings (None, Throttle Only, No Throttle)??

[bluessv]

Anybody?? Maybe Chris or Bill can chime in??

[Chris@HPTuners]

Tip-In is throttle tip-in, ie. when you increase throttle during a shift.

Flare is downshift to prevent engine flaring mostly when skip shift via neutral (eg. 4-2 shift).

I don't exactly know what "Limit Tq Mgt" is, i just made the name up and added the method to disable it.

The "method" is really a suggestion to the ECM. "None" doesn't necessarily mean it will not attempt tq mgt. post #1 gives exact details how to disable all Clutch based transmission tq mgt for upshifts and now also downshifts.

[kllrvet]

I am running 2.23.3323.27855 beta right now, is there a newer version?

Tony

[Bill@HPTuners]

Yes.

[jimbos'ss]

anything new for the p12/p32 pcms, we requested skp sensor cal a while back and i was hoping we could get that. along with more idle tables ie throttle follower/cracker so on and so forth.

thanks
jim

Has anyone with an LNF tried this BETA yet? Any useful new features/tables?

[Dan Wendling]

Any ETA on control over the PWM (Pulse Width Modulation) in the A6 yet?

Neither actually.

Please email support with exactly what you are looking for whether scanner or editor related along with your .hpt file and any helpful scanner logs and a vcm suite infolog while connected to the vehicle in question

....

HPT: Any idea if or when this will be added?

Dunno, from the looks of it I have 67 table requests in que for various applications, I would need to see the email that was sent.

New Scanner MPIDs
- ETC Source (tells you what is currently controlling the throttle)
- ETC TqMgt Type (if torque mgt is active what is requesting throttle)
- Spark TqMgt Type (if torque mgt is active what is requesting spark)
- Fuel Cut TqMgt Type (if torque mgt is active what is requesting fuel cut)

Where are these MPIDs located in the scanner? I have searched thru all of the available PIDs and do not see them

Bump for an answer

[Bill@HPTuners]

They are only available in the beta software.
