does @Rob have a spare to play with?
Rob
I have an auto turbo 4.4 ECU if you want it @jamesinc
Rob
My C70 is already 4.4 and has an ARD tune in it for the moment so I am not to worried until bigger mods come.
I am interested in doing the 850AWD, I assume it has 4.3 but have not yet checked. I do have a Manual LPT AWD 4.4 ecu from the V70XC handy, it would make the ideal donor.
Rob
Les, I believe that all Turbo charged 850's are 4.3 with the exception of the Manual R which is 4.4.
Ex850R
That would have been my R then....

@clinton are you flashing new maps or are you editing the map? Also I'm guessing that you get a real time readout with 4.4.
clinton
I am flashing new maps. Almost all of the original maps are available for download, so you can start with what you have provided that is not custom already (e.g. ARD).
The real time readout is much improved in the modified version of the binaries that can be downloaded from the wiki. That whole dashboard in my first post is updated as you drive, and can be played back at a later time also. This is not possible on a normal ECU, even with special software, as the bandwidth for datalogging is very low.

Would it be possible to convert a non turbo 850 to 4.4 or are the harnesses completely different?
clinton
Some of the non turbos had different ECUs altogether (denso I think) but others had motronic, so maybe... Not 100% sure, sorry
Ex850R
Some of the NAs had 4.4 when the turbo hasnt , i saw that in a forum post i looked at this morning , just depended on the year!? Not sure the NA is going to gain much from it....But , ye never know!

I'm more into n/a performance these days, I think it would be interesting to see what sort of power they could make. The atcc 850's made 300 odd horsepower, albeit full house motors, but there is obviously potential.
nickm
@jamesinc are you game?
The BTCC did make that power but at very high rpm and the head had the valve angles modified. I'm not sure what cams they ran. So options for NA more fuel timing and up the limiter I guess...
Ex850R
And the usual exhaust and intake?
I think there is a thread in VS for NA upgrades.
jamesinc
@nickm game for 4.4 conversion? Yes.
nickm
Will @Rob donate a ECU? So we can sort the AC control..then on to boost.
Rob
@nickm @jamesinc Mmm... I see an opportunity here.
I will send you 2
1x 4.4 HPT Auto for James
1x 4.4 LPT Manual for Me
Once you have James' successfully working without frying the a/c, you can do mine.. oh, and I need the little switch installed :)
jamesinc
I am good with circuit boards. Would you be interested in a key switch (i.e. the switch is you putting a key in and turning it). I like key switches.

With a red flippy up thingy on top? Those are cool.

nickm;45289 wroteCan't you just mod the vag cable? Next would be to decide what map to up load early V70R?

can this be used?
Yeh, you can use those bins - you might need to modify them though. Some will be setup to use different sensors, based upon region, etc, but it is pretty easy to turn such stuff off.
Why not start with the 607/608 binaries, as these are modified to provide good logging. You can then pull maps from anywhere (including making your own) to try different settings out. It is easy to replace a whole fuel/ignition/load map.
