I'll let you know how it goes

So how is it going?

This is a link to a thread I created to try raise awareness that (at least the BAS 150 Autobiography tune) is not just about the power/torque boost.

Improvements to TDCi driving experience

If anyone here gets into the Autobiography tune and find a similar experience - please do share in the thread above.

I am thinking this is a bit of a paradigm shift. Apparently validated by LR themselves in that they do a 150hp smooth tune for their Celebration edition Autobiography Defenders.

As tact quite rightly mentions it not all about power power power.

I hilighted and showed publiclly to all its readers and Landrover where the driving problem was starting from way back in March this year and have been working on the solution a lot longer than that part time in the back ground and had to be "koi" about what I posted at the time so I didnt get bombarded with when will it be ready questions.

It does seem to stem from my original post that all of a sudden every other tuner is working out the smooth problems within their maps. I wonder where they saw the problem hilighted

To get the full understanding of mt quoted reply I paste here but will need to read the thread.

Note that at 0.781% throttle and in some cases 2.344% throttle their is a minus torque request figure as standard, the jerking will no doubt be coming from the transition as you throttle between 0.781% no throttle and upto 5.859% where the request goes from a minus NM request to a positive NM request with quite a jump.

1st gear difference between the two is 35.284Nm jump
2nd gear difference between the two is 46.406Nm jump
3rd gear difference between the two is 46.406Nm jump
4th gear difference between the two is 46.406Nm jump
5th gear difference between the two is 49.562Nm jump
6th gear difference between the two is 121.594Nm jump. This is the one that when cruising on the motorway at speed gives you the drivetrain clunk when you come on and off the the throttle.

Other maps also change things about a little but a tuner worth their salt should know that and so more changes may be needed to find a work round and fix the quirk should they wish to tackle it.

BUT the point im making is to jump between a minus Nm figure and a positive Nm figure on very small throttle action can give a big jump in Nm the engine is producing and so make a jerking action as it makes power then not then does then not etc etc.

The above said its not the tuners responcibility at idle speed as I personally feel its a fault built into the factory calibration. If eniough people complain to LR correctly about it they should be forced into making a real fix for it and not just leave it with unhappy people and cars.

Normal remap tuning is not designed or aimed to fix all LR factory quirks especially at idle speed type rpms if im honest, especially with no throttle action going on and so really its not your tuners fault or problem in the politest possibile way. Providing they have not messed with something in that area at the time of your remap they dont understand

Its also may be worth having done on the car the PCM service adaptation reset.

Hope that all makes sense.

PS who did your remap ?

EGR commanded closed now as standard within the 150bhp AB remap, as well as fast write option for tuned files which only takes 65 seconds to write and not the full 4 mins 40 seconds.

Click Firmware update to B2444 and it will update/overwrite if already on this build the BAS2 main firmware and re apply the tuning files to the tool. Enjoy...


More good news coming very soon for 2.4 Puma owners... back to the Matrix for me now

...

2.4 owner here, looking forward to your good news then.

Not disagreeing with you, I don't need more power, that's not the reason I'm thinking about it, but as you yourself said....

[/QUOTE]Just think of the extra poke as a bonus. When you do tap it ... its a nice feel too.[/QUOTE]

Here's a thought,
With the Autobiography massive 150 hp being endorsed by LR in an upspec model, we may have an argument to make in a warranty claim if we do the same to a lesser model , or i could just swap the ECU at service time.

A quick reminder that the BAS Group buy offer finishes tomorrow Sunday 5th at midnight AEST.
