One I'm sure has been discussed before but does anyone know for sure what, if any, the differences are with the engine between the 3.0d 237hp and the 3.0d 271hp versions?

I've read that the injectors and some exhaust parts are different but otherwise the main engine is the same. However I've also heard that there are no differences are all and it's all down to the ECU.

A long time ago in a far away place, Spires wrote that the injectors were different between the two versions. Not sure if the gearbox would need to run a different program as well though.

I read that as well however it's not stated whether they were both from the same MY.

Also difference with the 300hp version. I presume there will be more differences as this is Euro 6?

With my old 140hp Ford diesel it was supposed to be possible to change the config to the 163hp version. When you then went on Ford IDS it would update it with the 163hp PCM download and you would then have a 163 engine. Can something similar be done with the 237hp engine?

Not so easy as on Ford IDS, in JLR SDD needs Engineer Code for ref lash ECU with different firmware.

I would drop Spires a message Chris, they should be able to give you a definitive answer :)

@MickAdams you ask a good question on Facebook.

"Why do the two engines remap to different values of the engines are the same."

Sorry we don't mean why are their different power output engines, that's a given.

The question is why when you remap a 237hp engine can it only really achieve 300-310hp (based on the remap companies I've looked at) whereas the 271hp engine can be taken up to 350+. Surely both engines can be tuned to the same level.

Who me? Nope. Someone asked on Facebook and, as here, there were conflicting answers. Some say they are the same, some say different.

Oh, the "friend" ;)

As far as i know - it's injectors & exhaust for sure, but maybe valves too.
