hi guys i have a jaguar x350 4.2 2003
ive bought some software mongoose v131 sdd all seems to be working fine up until i try to configure the gearbox it asks for calibration files to be downloaded i cant seems to find any files can anybody help put me in the right direction

 

Not sure how to advise you, in regards to flashing the trans
Any Mongoose interface, other than a genuine Drew Mongoose.
Could be an issue, its a luck of the draw, from what i have read
Be sure to have plenty of clean charging capacity, going to your battery.
Good luck to you

 

Did you replace the TCM/Mechatronic? Otherwise you shouldn't need to re-flash or reconfigure it. Now, if you're wanting to reset adaptations, I've been able to do the adaptation reset with SDD and a Mongoose clone, without issue. And as Wing said, you want to have a stout 12v power supply connected while doing any programming.

 

You almost for sure should not be trying to reflash.

If you are, you MUST have the hefty kind of power supply (Midtronics) or expect to brick the car.

 

thanks i will check with the garage that changed the oil

 

I flashed my gearbox some time ago with a cloned mongoose. It took 1.5hours, which was hard to believe. This requires strong battery support, not to loose your 12V.
My hope was to get rid of hunting, which didn't work.

You should just re-adapt. For this, there is a procedure in SDD, which shows you a checklist how to do it.
It's quite fun to do it, but you need some lonely road to do it.
After adaptation, you need to drive some more, then you should have smooth shifting.

 

ok thanks will see if i can find that
