must assemble and install, however, this project will require the use of a shop press and some specialty tools (or their home made equivalent :icon_idea: )
Glad you are happy!...4 wheel drifting in the rain :woohoo:
the computer that runs the MPT system want to see slippage of the front wheels before it sends power to the rearGlad you are happy!
How differently did it behave before the mod ? No 4 wheel drifting in the rain?
I 've read that no more front wheels spinning before the rears kick in but what about tight corner drifting?
How different is it now? Any snow/mud drift differences experience?
Can you explain the fuse thing some more? Do you usually leave the fuse in permanently with the VDC conversion?Well winter weather made taking the FWD fuse out a plus (the front tires were spinning in the rain)
but when I get on it in first gear it triggers the flashing AWD light....the "it thinks the tires are of different sizes" thing...
a new TCU out of a VDC vehicle is ~$500 and I don't KNOW that it would work, I think the wire to that light is going to get cut
but beside the flashing light it works great...4 wheel drifting in the rain :woohoo:
Driving fast an MPT N/A I noticed that when I was suddenly lifting my foot from the gas pedal in a very tight corner, the tail would feel very light and this enabled me to easily flick the tail out and turn the corner with four wheels drifting pressing fully the gas pedal again.... tight turns under hard acceleration is far more balanced feeling and doesn't have the binding feeling (and the rear will get loose if I want :biggrin:, which was almost impossible with the MPT)...

I have used that technique to get the ass end of 1 ton vans loose..... :biggrin:Driving fast an MPT N/A I noticed that when I was suddenly lifting my foot from the gas pedal in a very tight corner, the tail would feel very light and this enabled me to easily flick the tail out and turn the corner with four wheels drifting pressing fully the gas pedal again.
This light feeling was fun but it was not a consistent behavior and I almost went off a gravel road when the tail proved too lightweight when I tried the same technique.
With the VTD conversion how much different the above may be?
Is the behavior more consistent? More difficult to flick the tail while braking and easier when accelerating?
Differences when braking INSIDE the corner? (The MPT is supposed to disengage more when braking...)
Any differences when hard braking when going straight ahead?
Thanks for the feedback!
I suppose that this may happen because with the MPT there is no way that the rear axle can spin faster than the front axle (not the wheels but the axles towards the diffs which are sensed by the TCU sensors) while with the VTD this can happen so it thinks of the "different size" issue...but when I get on it in first gear it triggers the flashing AWD light....the "it thinks the tires are of different sizes" thing...
I am in the process of replacing the rear diff so the car is broke right nowAny news?
Have you hooked up the VTD clutch?
:icon_biggrin: hehe, going the simple and hard way! Electronics can make it easier and softer but if you have no-one around to fix this for you, it is better to stick with what you know.... I plan on grinding it down and using my wire feed to build it back up then cutting the same number of teeth as the MPT setup into it
I think that this must be so because with the MPT the rear axle cannot rotate faster than the front axle during acceleration while with the not-yet-connected VTD (and the MT models until the LSD kicks in) it can, so you can have power oversteer when the rear axle rotates faster than the front (although on low grip conditions, the rear axle may not turn faster for oversteer to occur). When you properly hook up the VTD clutch, the oversteer should be reduced....(and the rear will get loose if I want :biggrin:, which was almost impossible with the MPT)...
I do the same thing lol. The MPT also shifts power rearward with more throttle, but seems to shift it forward when you left off, so it behaves like a fwd car in regard to lift off oversteer.Driving fast an MPT N/A I noticed that when I was suddenly lifting my foot from the gas pedal in a very tight corner, the tail would feel very light and this enabled me to easily flick the tail out and turn the corner with four wheels drifting pressing fully the gas pedal again.

do you know where to get one ?a speedo calibrator box would do the same job.
stock execpt for the resistor , TC and VTDGood work andy. Just because I dont remember but are you still on the stock trans or are you ipt built?
I am going to keep the same diameter and hope that the teeth that I cut don't have to be too close together for the sensor to 'see':icon_biggrin: hehe, going the simple and hard way! Electronics can make it easier and softer but if you have no-one around to fix this for you, it is better to stick with what you know.
Have in mind, this must be a "hall effect" inductive sensor so your hand made teeth must be around 0.5 to 1mm max away from the sensor.
the pinout in the FSM shows the same for both in the 06 FXT but I am pretty sure the programing is different as the VDC cars have different modules that communicate with it over the CAN busI do the same thing lol. The MPT also shifts power rearward with more throttle, but seems to shift it forward when you left off, so it behaves like a fwd car in regard to lift off oversteer.
Does anyone know if the pinout for the VTD TCU is the same as the MPT TCU? I'm thinking if my trans goes I'll try a full VTD 4eat swap.
Only the 2007 - 2008 Forester XT VTD diffs are confirmed to workSo if I go junkyard diving for a VTD center diff... is the general concensus that any 4EAT VTD diff will fit?
AFAIK, a6n6d6y is the only person on the forum to do the conversion.Also, anybody have any problems after conversion, other than the nagging AWD light?
