Can someone chime in on what the settings for Torque Management actually do. Sorry for the newbie question. Main thing I'm looking for is Spark A, Spark B, FSO A, FSO B, ETC A and ETC B. I understand the acronyms but not the "A or B"

Any links to previous topics would work also. Tried to search for any previous posts but haven’t seen any info on the subject. Also on the bottom description of the hptuners editor it says “dyno flag” on or off.
Thanks in advance
This is something I'll get to updating here when I get some free time. Some things in the section have poor labels and descriptions. When I get a chance I'll clean them up.
Dyno flag was a misinterpretation of what was actually happening.
The true input is when drive torque control requests from the transmission are being received or not.
"A" is when these requests are received.
"B" is when these requests aren't received.
A is going to happen when the transmission requests a torque regulation, i.e. reduction for shift.
B will happen if the transmission does not make a direct torque request (but the ECU calculates a need for a torque reduction regardless)
Awesome thanks for the explanation. Look forward to the updates.Originally Posted by Steven@HPTuners
On the ZF8HP, with ALL engine (PCM) tq mngmt switches turned off, the trans is unable to cut tq for a shift.

Why do some adjust these settings example turn on Use ETC B when its a manual car?
