Mine is a 2017 150bhp 2.3
Quite a few people with these, both on this site and elsewhere, find them either underpowered or too high geared. Mine certainly is compared to my previous 2014 150bhp Ducato which flew along motorways without the need to change down on hills.

Has anybody any experience or knowledge of remapping these particular engines? There are many companies listing them and showing expected performance figures.

Hi, i would give Celtic tuning a ring and have a chat with them, they will come to you to do it, ours is an earlier 2.8 jtd but the remap has made it a different vehicle and so much easier and quieter to drive, and on a trip round South Wales recently it was giving near 30 mpg. If your not happy within 14 days they will put it back to standard foc.

I used Celtic Tuning and was very happy with the result. But it appears from this thread that I could have saved the money by just getting the ECU software update to v32, which appears to give similar results. 😐

My 2016 Euro 5 engine in 150bhp spec has returned a whisker under 32mpg on my Carthago 138 Compactline A Class over the two years since I acquired it and that is running at it's plated weight of 3500Kg. I doubt it's worth fiddling with (If it ain't broke...) to try and eke another mile or two and might mess it up. My 2016 Majestic 125 with the 150bhp Euro 5 Pug engine which ran at just under 3300Kg produced virtually identical figures over a two year period.

I suspect it doesn't give the same results, but it seems to be better than it was and I was suggesting it might be 'good enough'.

I have a 2018 150bhp with comformatic. Never heard of this "up" button 🤔. What does it look like and where is it?

In front of the gear lever, it holds gears longer before changing up or down, essential when driving in mountians.

Thanks for that Lenny (y):giggle:. I actually looked in the handbook :whatthe: and found the reference to the "UP" function. Wasn`t very informative as to what it actually does! Previously, when mountain driving, if the gearbox was constantly shuffling up and down, I`d wait `til it shifted down then flip the gear lever over into manual, this forced it to hold that gear. Worked for me but I`ll give this "UP" function a go next time we`re "up" a mountain :cool::giggle:

We have had two Fiat 2.3 150 bhp powered vans and found they were plenty powerful enough we even towed a car trailer with the last one it never missed a beat😊

It seems to be the euro 6 lump that lacks the umph

So have I. But it seems to apply to specific year/engines

I have the same spec engine and year with comfortmatic.
Found it difficult on inclines or behind lorries trundling along at 57 mph.
Had it remapped by Quantum for £230 up to 180 hp once the 3 year warranty expired.
So much improvement-can breeze past lorries uphill at 65mph in 6th gear. Slightly better fuel consumption and a pleasure to drive

Nothing to do with Fiat but ....... I had my Merc V6 auto motorhome done by Quantum a year ago. It wasn't lacking in power or torque but I thought it could be better. I'm very happy with it. Idling is smoother and it holds rpm much better on motorway inclines. Using cruise control at 65mph it didn't change down pulling trailer & Smart car from the Lune Gorge to Burton Services heading North on the M6. Before tuning it changed down one gear under the same circumstances. (just an example of somewhere I noticed a marked difference).

Delighted with my 2016 model, remappd by Celtic in 2017 and going well at just over 20,000 miles

Had my 2020 non ad blue 2.3L 130bhp re-mapped by ACE done a few months ago as it seemed pretty gutless. A major difference now in the 55-65 speed area without the changing down for slight hills!! I've had many with 2.3L 130/150 and 180bhp and never thought I needed a re-map. This one as mentioned did! I think some engines either have it or they don't, maybe how they were treated from day one but who knows??

Comes up too often so I think the common denominator is this engine, not how it's been treated. Also 16" wheels play a part.

Had my 2019 Euro 6 Pre Adblue done yesterday, early signs are very positive, the guys at quantum tuning here in Spain dome a great job. Took it for a spin last night on some known roads where it would need a change down to 5th and all good, managing to stay in top gear. I can feel the difference very early on. We are going to take it inland over the weekend as some more challenging hills there so will update my post once we have done that , but as I say early signs are very good.

Good news then - same as mine - it makes quite a difference!

Surely depends on tyre size rather than wheel diameter?

You'd think. But the tyre side wall ends up being nearly the same. From Fiats standard fit tyres, the biggest 16" has a rolling circumference nearly 10% bigger than common 15" fits... No wonder the speedo is so far out on some vans!

And everything was designed to run on the standard 15inch wheels. The gear ratios, final drive ratio are changed by 10% on a 16inch wheel. My solution is to drive one gear lower much of the time and not use 5th much below 50 or 6th below 60. Yes the engine will pull those gears below those speeds but if you watch the instant mpg readout it works harder and drinks fuel as soon as there is even the slightest incline. I live in Scotland where there is very little flat road and after testing on the same journey several times have come to the conclusion that trying to use high gear with 16inch wheels uses more fuel.

I do agree that 16" wheels seem to make the gearing too high. And that it was probably optimised for delivery vans that run the cheapest spec, so 15".

I did a rough calculation. A motorhome has 25% more frontal area than a PVC. So not surprising that high speeds are more work.

If you have a Comfortmatic the UP button helps to achieve similar results. It holds lower gears a bit longer and changes down a bit sooner.

so you would reccommend staying on 15" wheels

16" wheels look nicer. And I think they have a higher load rating if you're running a big van? Might be a better tyre choice too?

But they are heavier, accelerate slower, and the larger diameter isn't so good on the 6 speed box.

the only reason i was concidering changing (steel) was for load rating and better choice of all seasons .
