Dear forum members,
do any of you have any thoughts about setting up the turbo table - TC Duty Cycle Pilot Control and Target Load Setpoint.
I can't understand the relationship between these two tables. TC Duty Cycle Pilot Control table has the same values, but the values in Target Load Setpoint ...

My stuff wouldn't be very useful to you.

As I mentioned, I'm running a WBO2 Modulation bin, so I don't have a VE map. It's an AFR Target map.

Also, my turbo control parameters probably aren't spicy enough for you. I'm only at about 12-13 psi. Mainly because I haven't had the time to really mess ...

Volvo 850 1996 T5 Auto

I have flashed the 607 bin on a M4.4 ECU 0261204449 from a S70 Automatic HPT 2.3.
Calibrated injectors to the Bosch orange ones according to the M44 Wiki.
AC mod, turned off the diagnostics for SAS etc. disabled rear cat check - I got CEL with it enabled: rear HO2S EFI-153 ...

I'd have to dig back in the VS thread, but I think the base "DIY M4.4" stuff has the selectable maps, but I could be wrong.
I know there are alternative maps listed in the XDF. I don't remember how you select them though.

In run all of my turbo cars on the 93 PON octane. This is equivalent to 98 ...

I know VAST has an option in his ECUs for an alternate mapset-

Alternate Mapset: A second map set, allowing you to switch injector calibrations, fuel map, ignition map and boost maps on the fly, without the need to flash a new tune. Usually this is used for a gasoline and E85 map, but can be ...

Hello everyone! :!: :!: :!:
Does anyone have an opinion on how the ECU works on different types of octane fuel?
Does the ECU understand the different octane number and is it possible to make adjustments for fuel with a lower octane number?
Maybe it is possible to introduce some kind of correction ...

As I understand it, this post pursued the same goals as I did. But I thoughtfully read the algorithm several times and I also don't have a complete understanding of how to properly configure the turbo for the new one TCV.

Dear friends, Hi!
I have a question to ask you. I recently made several upgrades to my 850.

Firstly, I replaced the TCV (Turbo Control Valve), put it from V70. The same valve on the XC90, etc.

After that, I flashed this firmware, - 607_ rev5c _test-tcvhack-850_tweak21.bin

In this firmware, I ...

A PWM option for fan control would be a great upgrade.

Can you post a screen shot of which fan parameter you changed? Like I mentioned, I recall several different fan control parameters.
Perhaps one of them could also be used to turn on the fan in low-speed mode (like when the AC is engaged ...

Hello everybody! The interim results are as follows. The basis for the fan operation parameters was to take XDF "REV6-RadFan-Control.xdf". From it, I copied the fan operation parameters into my working XDF. I have changed only the switching temperature so far. Instead of 102, I put 90. Now the ...
