d150 AB Tune BAS Queery

[ngarigo]

hey guys, what difference is there in off road performance with the 150 AB tune in a 2.4 puma....?

To make it easier for people to answer define "Off Road"
Do you mean dirt tracks (yes this is off road to some people) climbing sand dunes or pulling through sandy river beds fully loaded?

i was interested in the observed differences and experience driving the vehicle after the tune, off bitumen, whether it be shlepping through sand or tootling around fire trails... to be clear, i’m not so much interested in making the vehicle faster, i live in alice, 80% of my driving is unsealed road and track, stone and sand... i don’t tow caravans and could care less about hooning around on the blacktop.... the remap for me is about getting the damned egr shut and a smoother driving experience will be a bonus.... i am happy with how the wagon currently performs off road and was just wondering what changes, if any, folks noticed after the tune when driving in low box.... thanks

I went the 170 and bigger I/C from BAS. my bus: https://www.aulro.com/afvb/introduct...ml#post2634379

The torque increase is impressive and pretty handy. Sand is the only place I've noticed a significant difference though.

Also of note, when i got it the 170 was something like $50 extra and comes with the 150 tune too - so you can swap about standard / 150 / 170 as you please.

Hi

On my Defender Puma 130 the 150 or 170 tune - does not matter which - improves life off road mainly because the low rev/partial throttle (fuel delivery?) is far smoother.
As you have said outright power makes little or no difference in most off road driving - soft sand excepted.

In fact removing all the drive train backlash was the biggest improvement off road I have made to my 130. . The BAS tune helps by making it easier to avoid shunting the drive line when tackling slower off road situations.
For comparison my old V8 1985 County was far smoother (& better - engine low end response, drivetrain and softer suspension) off road than my new puma - but I'm getting the Puma there.

Great question ngarigo. Thanks for feedback all. I'm thinking if getting a BAS tune and I've been thinking similar questioning re off road performance. Feedback in all conditions would be great to hear. All the focus so far has been on on-road performance. ...Low down torque improvement and even better throttle control would obviously be great...is this everyone's experience with various BAS tunes?

One thing that's slowed me down re ordering BAS has been the fact that you no longer get a spare ecu with the package. I asked BAS but they said it's become too expensive. I wonder if a special group buy might help re-introduce the spare ecu? Anyone interested?

I have the 150 in a 2.4 130, mainly to bypass the repeated EGR failures. I don't find it hugely different to the standard tune, unless I really put the Welly into it, which is not my style. The torque is noticeable up in the high country, less gear changes as it hangs on while climbing, which it does remarkably well for a vehicle of this size. The rather erratic fuel consumption I had (up to 150 km's difference a tank for no discernible reason) has also evened out.
I had heard some rave revues about the tune and the huge change it makes to the 2.4 which did seem a little far fetched, and took with a grain of salt, so the tune has delivered what I expected.
Hardest part was getting my head around doing the actual retune, not exactly a simple step by step guide for the IT illiterate, thankfully I was able to handball it to my favourite Motorcycle mechanic. (thanks Kelly).

Thanks for the straight up feedback. Sounds like its been worthwhile. Cheers

thanks folks that sounds pretty useful still.... i was concerned it was all about improving on road performance... 👍🏻👍🏻👍🏻

I didn't have my defender more than a year and a half when I put the tune in. What I noticed first was how much smoother it was in low range over very uneven ground. It makes it a breeze. Never tried the standard tune or 150 on sand but in the 170 it scoffs at sand of any kind. On all kinds of dirt roads it seems to be more controllable but that could also be put down to more experience in the vehicle and the greater knowledge gleaned from this sight. Although you're not really interested in on road, the difference there is a revelation to say the least. Get it. You won't regret it, I promise you.

Also, the ability to clear faults is a major bonus, especially in your neck of the woods, I'd imagine.
