FGX G6E TURBO BUILD

[bossmang]

oh I didnt even know haltech could do that!

Tune switching is available on the stock pcm which can have multiple tunes. The stock pcm can also tune the ZF transmission, which the haltech can't.

 

If you run a plugin haltech you have to use another program to tune the ZF transmission, which will be PCMTec if you are going to a workshop.

 

Stock pcm = good.

Haltech = good.

 

They're different things for different purposes but imho there would have to be a compelling reason to switch from the stock/custom os pcm to a haltech.

Im not completely across the PCMTec stuff but I can tell you that line pressure can be adjusted through the modification of the torque model table within the Haltech software. Shift point load can also be adjusted along with torque reduction responses.

 

You cant adjust shift schedules or overlaps.

You can’t adjust any torque reduction requests.

That needs to be done directly through OBDII writing to the TCM. You can turn off torque reduction although I think this is ignition cut for smaller reductions rather then larger cut requests.

 

If you run a stock rev limit and run a stock TCM tune you can actually make some changes using the Haltech. Although this is not directly writing to the TCM, its just modifying advertised torque data to the transmission to get it to respond differently.

 

Im hearing some of the best ZF tunes run surprisingly stock files. 

 

Im curious to know how the PCMTec stuff writes to the TCM through the ECU? Or is it a direct flash to the TCM.

@rollex can field this one for the most part.

 

In my experience the ZF file doesn't get changed much for stock hardware.

I know of a dead stock TCM tune being used on a $10000 built box. 850hp engine. All the “tuning” as such is done from within the Haltech!

don't quote me but haltech will be able to do zf stuff soon that is what I been told. 

PCMTEC has come a long way.

The reason I went haltech is I got EGT in my car, staged fuel setup, nos, co2 boost control.

if any one is going haltech just remb that plug in play ecu does not come with many input and out put I had to get two I/o box to make sure I had enough.

That's fair enough. With the power you're running you really want the most amount of tunability and safety features possible.

on the money!

I think that switch thing is a bloody ripper idea havent seen it before I want it. 

 

back in the day we had to pull over and flop out the xcal and sit there for 15 minutes in a servo and upload different tunes lol

[k31th]

15min is a slight exaggeration, but yeah... xcals are fine.
