am about to get my tow vehicle remapped. looking for thoughts from those who HAVE done it.
current vehicle 2013 BT50 XTR Dual cab. NO DPF.
Previous van was 2t loaded and achieved approx 13/14l/100klm fuel economy and towed well. New van 2,5t loaded fuel economy dropped [ as expected] to about 17/18l/100klm.
Not towing fuel economy very good just did a 1200k drive on the M1 and achieved 12.5klm/l
looking to get more torque than HP and talking to the reputable tuner this can be done with no pain to fuel economy.
My father in law has a BT50 2016 WITH a DPF had his done at same place and LOVES it, fuel economy improved noticeably and tows a van same weight as me and says its also noticeable.
Wondering what thoughts other on here that have done it are?, have heard all the nay sayers [ who don't tow] talked to my mechanic as well [ who also has had it done] and says its ok.
And am planning to keep the vehicle for some time.
Are you anywhere near Brisbane? Fella tuned my V8 Landcruiser Ute to give heaps more power,heaps more torque,and I get 5.8km/litre at 6800kg GCM. Cheers

No further south NSW. yes am hearing some pretty good numbers from many who have done it, just curious as to the nay sayers what they say.
I wonder you were getting 13/14l/100k towing a 2T van now towing a 2.5t van and it getting 17/18l/100k, I presume your vehicle has an auto transmission I hope you dont just put it in Drive and off you go, because if that the case then there's your issue.
I tow a 2.6t GTM van with a 3ltr 4 cyl diesel with a manual gearbox and in normal conditions fuel consumption is 14/15l/100k.
Do it. But do more homework.
Some people spend a lot of money
for little return, and won't admit it.
I had my 09 D Max done last year here in Adelaide, after much deliberation. Very happy.

How much is it to have the engine re-mapped ?
Yes its an auto AND YES I drive in D NOT S yes yes have heard it all before the good old debate of D v S mode, I have proved enough to myself it makes NO difference. How did I do it simple recent trip filled up at Barckely homestead NT and drove to tennent Ck in D recorded fuel economy on the way home filled up Tennent Ck drove to Barkley Homestead this time in S fuel economy almost to the same decimal point, and yes weather and wind the same and same speed maintained [ cruise control]. I do put it is S when going uphill or under a load but cruise in D.
I put the difference in economy down to the effort needed to get it going up to speed, I sat on 90kph the whole way to Darwin and back 8000klm round trip, previous van we did almost same route just turned south at the three ways not north to Darwin, same speed same vehicle compared fuel economy same driving methods.
As I said in original post my father in aw has same vehicle but with DPF was NOT impressed with its performance when towing [ or even when not] fuel economy wise, got a re-map and totally changed his mind.
costs seem to be about $1200-$1500 depending on outlet. am hearing the folding stuff gets it cheaper

Have been pondering for some time, not a quick decision heard all the nays and yays sought pro advise and this forum as well so far nothing has scared me off.

I'm not gunna try and alter your driving habits, because thats a waste of time. The proof is in the pudding even Mr Yobarr has great fuel ecom for his cruiser because its a manual, its easy to attain good fuel ecom with a manual.
You may get away with it driving in Drive, but one day it might bite you on the ar$e and cook you gearbox because Drive is not for towing, I'd reckon your owners manual would mention using the correct mode when towing.

All I know is what I see and 250k on the clock and serviced every 10k and still goes well, had all the fluids checked before I left [ especially gearbox] and when I got back from 8000klm of towing and all good, I purchased this vehicle for just towing the van, its currently stock standard, I find in D it goes back to 5th on its own when required and when its in S will go into 6th whilst towing so why stay it S?
And way way off topic

You do not mention what you were getting before the re map, also units for economy are totally different and V8 v 4 cyl??
Just found figures for you! Power went up from 160hp at wheels to 197hp at wheels,so around 25% increase,while torque went from 450nm to 650nm,so increase of 45%.Cost a couple of dollars,but improvement is amazing,with maximum torque all the way from 1200rpm up to 3200rpm. Mate attests that he used my car to tow his 1.5 ton camper trailer from Penrith to Orange with only one gear change the whole way.Out in the bush at night,the sound of the little V8,through twin 3" pipes,echoing through the trees,is music to the ears! Nothing like a V8,and at 5.8km/litre ,or 17 litres/100km (16.5 mpg)when running at 6800kg GCM,I'm more than happy! Cheers

"Drive is not for towing" .Good point,Graham,and not only will towing in Drive likely "cook the gearbox",it also results in more fuel being used.Sad, inconvenient truth,understood by few.Cheers
I often wonder why some members ask for opinions on something then when someone points out a few problems that can occur, end up defending the decision that they apparently, have already made.

Our average towing our 2300-2350kg full sized van over the years has been around 12.5-13.5L/100km, including our trip to WA. Our issue was more that we are struggling down low, so asked for a specialised remap to address the towing from a standing start. Result has been no accelerator lag, through the first 2 gears more smoothly & no struggle off the line. Also in 4th we find we have just a tad more free acceleration for when needed.
Fuel results from recent trip:
Going there 16.2L/100km into a headwing prior to the remap. Previous same identical trips 12.5-13.5.
Return after remap 11.1L/100km. Acceleration from a standing start was effortless. On the freeway we were stuck in a long line behind a caravanner doing 75 in the 110 zone. Saw a mini gap in the outside lane, indicated & went past the convoy with ease without any impediment to other vehicles in the fast lane. in fact, we put a gap between us & them in aceelerating from 75kmh until we passed mr slow.
In relation to towing & gear usage, I always use S mode from start, when on the flat I switch to D. Any climbs, straight into S mode.
