Zf Tuning...

[The Jizard]

Ah thanks for that info Headsex.

[The Outsider]

so what will be the advantages of the zf tune?

[Headsex]

Increase shift pressure into 2nd to stop hitting the rev limitor in first gear when you have increased the power.

Improve longevity of the box by overall increasing shift pressures.

Typical things which have been done in the past to handle more power.

But I also see alot of broken input shafts. Considering we're already seeing twisted(and broken) input shafts with higher powered vehicles!

The ZF input shaft diameter is tiny, like something you'd see on a 4 cylinder barina.

The 4 speed auto has a input shaft diameter nearly double in size!!!

Is there a way of using the FG injector cut strategy on high load shifts on BF series auto's?

To me this is going to be of greatest value in reducing fatigue failures and reduce clutch wear/degradation.

[kartman]

Yes you can, I did it on a G6E some time ago, its sound cool too as it missfires on shift, it's a catch 22. If you want to ET fast you need to have the shift occur fast with no torque reduction. The ECU employs a number of torque reduction strategies that can be adjusted such as throttle, timing and fuel cut. The manufacturer uses them in order of the severity of reduction required. Timing first as it is fast reacting.

The FG injector cut is done in the PCM, nothing to do with the ZF..

I've turned it off on the FG's, as well as enabled it on BA/BF's for laughs..

There is 4 torque control methods used in the Ford strategies.

Spark Retard

Air/Fuel adjustment

Injector cut

Electronic throttle

Large torque reductions are done with the following priority -> Injector Cut, Air/Fuel adjustment, and then Spark retard.

Each one of these 4 methods can be adjusted, as well as enabled or disabled individually.

[rob82]

So you have been able to enable injector cut on shift in BA/BF auto's PCM's??

[Headsex]

Well. Yes to bf, haven't tried in Ba, bit the same tables are throughout all models, just disabled in Ba and bf

[IH8TOADS]

Yeah he's even re-scaled the t-MAP calibration!

Have a look at the requestors.

[Headsex]

Yes. Im running a 4bar Tmap AND 5bar iap.. And those values are not available in any software on the market!
