Only the fg 6 speed auto cannot be tuned. It makes no note of bseries 6 speed auto so I think it would do that too. All other transmissions seem to also be covered

HPT can't tune any ZF 6sp.....period.

Trana do you want the 4 bar data for your injectors?

The ebay guy doesnt say that on his ad about b series six speed but I am not surprised

If you really want to split hairs, ZF's are supported to the same degree they where supported by SCT (ie very limited) until SCT released the TCM flash capability. Ie the trans tables can be edited in the PCM, but the TCM will still have the final say.

Thanks heaps, I PMed my email

Just thought I would post my Theoretical calculations for Tuning. I know that this will differ from reality as to what can be done but it is just a case study to see where I start off (as being green to Ford Tuning) to where I end up.

This is my Theoretical calc sheet for the Bosch G302 GT500 injector

The base information was derived from the Injector calibration sheet. However I feel there may be a couple of errors on this sheet with the offset multipliers at 30 and 60 psi where they dont fit nicely into what is expected. So I have used my own interpolated figures for this.

Yeah this is one of the few calibrations where the Offset Multiplier doesn't fit the usual trend.

I have another calibration which doesn't have this unusual data. In addition check the HP tuners website for a stock GT500 file.

Thanks Toady. I did look up that GT500 file and it certainly is of help. It did bring up a question as follows.

I am trying make sense of the FNPW_HSCOMP and FNPW_LSCOMP tables.

The definitions in the HP Tuner are as follows

• Injector Flow Rate High Mult vs. Pressure: Injector flow rate multiplier used to compensate injector flow rate for fuel pressure differences.
  
• Injector Flow Rate Low Mult vs. Pressure: Injector flow rate multiplier used to compensate injector flow rate for fuel pressure differences.
  

So I can clearly understand how it works if we have a returnless fuel system which I think would have a pressure sender somewhere in the fuel line to electronically measure fuel pressure.

However we don’t have a fuel pressure sender in the fuel line in the Ford turbo nor a returnless fuel system.

However in the Ford extracted HP tunes for both the BA/BF/FG these tables read as follows.

Injector Flow Rate High Multi VS Pressure

Labels Multiplier

0.0kpa 0.000

8.6kpa 0.044

17.2 kpa 0.063

25.9kpa 0.077

103.4kpa 1.225

103.4kpa 1.225

The label colum is in KPa, so 103kpa us around 15psi. So this cant relate to fuel pressure and there is no fuel pressure sender.

Somehow could it relate to manifold pressure. Otherwise why wouldn’t there just be 1.000 in the multiplier column??????

I might also ask this on the HP tuner forum.

They're not active

Thanks again
