Default Good news ECU tune possible on S-Type as well!

Hey guys!
So I have been doing ECU tuning for XK xkr and XF and R cars, 4.2 and 5.0 for a while now, but have not had an S-Type type during all this time to see if I can do it. Well I Just had an '05 S-Type 4.2 and did a successful tune . Reflash done through obd2 So no need to take out the ECU. Good amount of torque gain on stock 4.2 S-Type And of course there's more gain on the type R.
Can can do custom tuning request such as mass air flow rescaling , cooling fan temperature modification and more..
Probably easier to reach me on Skype SeekerAlex ..

well that’s cool. I have a 2006 STR. I’ve got the induction tube changed to the smooth metal one, the smaller supercharger pulley and the bosch supercharger pump. What parameters do you change and what are your final goals with the tune- what are the adjustments? How much hp/tq do you think you can make on a supercharged 4.2 like mine?

The adjustments are based on my 4.2 XKR which is very similar so I would expect similar gains as you can see I'm at near 100 horsepower gain with basic bolt ons. And as far as parameters there's a lot but the basic ones is spark, air fuel ratio, pulley ratio, boost and many many torque limiters and such, I can also custom adjust cooling fan speed and kick on temperature for better cooling. Also if you want high flow catalytic converters or a decat I can take care of that as well in tuning.

II guess what I can do if you want to be the first person to do before and after Dyno or track time we can discuss a discount

well my cars running pretty good right now with all of the leaks sealed and good o2 sensor data. So lets talk a bit. Heres from today when I was chasing a weird speed data fault on various modules.

You take your life in your hand programming these cars. One slip up and youre hosed.

Hell yeah

No faults yet....... cross my fingers

Looking good!

I have spent hundreds and hundreds of hours working on these ecus. At this point have been doing it for years now, and have spent way more time than others developing and testing on my own car. Lots of very happy xk Xkr , xf xfr owners so far. You don't need to tell me about slip-ups send me a message from Skype or WhatsApp we can discuss.

Hello! What can you say about the ability to tune models before 2002, with an ECU from Ford?

Default Remapping for S Type Still Available?

I have an 03 S-Type with the 4.2 NA. I've added an aftermarket cold air intake (like a K&N), free flow cats and mufflers. Will your tune get the engine to make the most of these mods?

If helpful i can provide the live OBD2 data i have.

Thanks
