Just buy the cheaper one and remap it....

One of the recent transporters comes in 84hp and higher power versions, no hardware differences resulting in huge map gains.
Do you mean they all remap to the same power output?k-ink said:
Interesting thread. I wouldn't be suprised if some car infotainment systems were artificially limited unless you pay a premium for certain functions to be unlocked. It would be cheaper to make all units identical rather than multiple different units. Just a theory mind you.
On a similar vein, my old mondeo didn't have motion autolock or one-touch windows or windows via the keyfob. Pressing a few buttons in the right sequence (found on the interweb) brought them to life.TheAngryDog said:
Mg Zt / rover 75 cdti 114 was identical to the 131 engine apart from a remap.
A lot of "remappers" don't realise this.

Started life in a 115 tune, then (supposedly once BMW had left) a 135 tune was developed. Same engine, different mapping only, no other differences.
Upgrade was offered as an optional extra (from the factory), or as a dealer-fit retrofit for existing owners.

BMW 114 f20/21
Remap from 102bhp to 200- 220bhp. wow
I guess same engine as 116 and 118.
Sounds do-able with a 1.6 turbo. Seems unlikely that BMW would leave the door open for people to buy a 1 series and remap it with the power of a much more expensive 1 series. Surely there must be some difference other than the map.Remap from 102bhp to 200- 220bhp. wow

from what I can see no difference beside a remap, it sounds stupid but makes better financial sense really, economies of scale.Just because a car will remap to the same power as a similar model, doesn't mean the car is identical from a mechanical perspective. Often the higher power output cars will have uprated and/or extra components to better cope with the extra power (larger intercooler, dedicated oil cooler etc.) that the remapped cars won't benefit from.
I'd like to know the differences in the engine between the F56 Cooper S and JCW as most remappers' stage 1 puts them both to ~289 BHP, can't be any significant differences?
The old VAG 1.9 TDI lump had larger turbos, injectors and stronger head bolts as you jumped from 130 to 150/170 BHP versions, the 110 to 130 was pretty much just a larger Turbo. You could get 170 BHP out of the 130 BHP unit, but the bigger unit could go much further as the injectors fitted to the 130/110 didn't have a lot of head room left.

I don't think Dodgy Daves Remaps are going to be able to increase the rating of one of those with an old lap top though
I bet they'd have a crack at it, how hard could it be?
i can picture a pilot sitting in the cockpit looking at a Bluefin handheld waiting for the map to uploadFlashing traction control light and airbag warning is on and its defaulted to limp home mode - better land it and pull the negative battery lead and give it 30 seconds and see if it resets. "think daves saxo had the same last week" the pilot expalins to air traffic control.

Not quite in the same category but the Rolls Royce engines on a new Dreamliner!

Jag XF?
The supercharged V8s are predominately mapping differences, although there are coincidental intake and exhaust differences too (the latter mostly to improve the sound). There are well published differences to front uprights/wheel bearings/hubs, springs & dampers, steering rack and gearbox between the R and R-S too that make a true conversion fairly unfeasible. The diesel engines don't interest me, but I do know that upgrading a 3.0d non-S to S spec is also fairly impractical on the face of it because the S model came with adaptive dynamics function (the Dynamic button) which changes damper rates, accelerator pedal and gearbox mapping and it wasn't standard on non-S models. It was expensive as a cost option, and most people who went for the cheap engine weren't interested in driving anyway. The S models also got much better seats.
The XFs can be remapped to increase the power, but that's all. Certainly from the perspective of the V8s - the difference in performance is all down to the steering and suspension improvements. The gearbox upgrade is nice and the engine power difference is irrelevant on the road.
The different power outputs of the Rover KV6 involved different camshafts - the tool set for locking the camshafts to change the timing belts has different tools to fit the camshaft sprockets depending on power spec.

I had a look out of curiosity and there's at least one company claiming 210 from all the 2.0 tdi transporter engines after a remap. I would be absolutely astounded if the 84 has the exact same internals as the most powerful version (but I'm not saying it definitely hasn't as I just don't know). 250% uplift in power seems far too good to be true (and reliable)
IIRC there are two engines, a single and a twin turbo. The 84hp is single, and identical to the 102hp motor except for the map. So they will both map up to around the same power. The 140 & 180hp motors are twin turbo, I think. ModernAndy said:

looks like they just chop the maps off at different points, the 114 runs out of puff at 4000 rpm !
