330d remap compared to 335d

[lord trumpton]

Hi All

Just wondering if there is anyone who can give their opinion here....?

I'm looking to get either a 330d or a 335d in e9X form. I would prefer the 335d purely because of the extra poke but finding a nice one is harder than finding a nice 330d

Anyway my question - If a 330d was remapped then on paper it offers similar output to the 335d. Has anyone followed this route and how would the two compare in the real world?

Many thanks

I am thinking of pulling the trigger on getting my 330d remapped, as like you say a map will offer similar performance to a 335. I will be interested to read any replies to this.

I had a mapped 335d but couldn't live with the auto box. Its only available in Auto.
I wish I had bought a 330d with a manual box and mapped that.

The 330d and manual box is a good combination. I didn't get mine mapped though.

I had my LCI E92 330d auto remapped by DMS from 245bhp to 305bhp.

Having driven a standard 335d LCI at 286bhp ... the remapped 330d was definitely quicker but the 335d was smoother in delivery. Remap a 335d and you are obviously upping the game again.

The std 335d was easy to put the power down, My remapped 330d was altogether more aggressive in delivery, quicker but not so easy to use the power. I guess as it had an extra 20bhp over the 335d and was deploying via one turbo as opposed to two.

The turbos are sequential, so only one at a time. small for low down and big for higher up the revs. Its to overcome lag not more power.
With one you will get a surge of power higher up the revs but will feel lethargic low down, and in a diesel its annoying.
My 335d had an Evolve switch. 350 bhp and 510lb ft torque which could be switched to standard.
In standard with 286bhp it felt slow after the map.
The gearbox gave no control just an unnecessary kick down, which put it to the end of the power band and setting off from road ends fast resulted in nothing, then everything and flashing lights with power cuts.

How well did your clutch cope with the extra torque ? My understanding is that the 335 was auto only because the manual box couldn't cope; if the 330d is mapped to 335 levels, or higher in your case, clutch life could be a problem.

My understanding was the gearbox on the LCI 330d was in fact the same as the 335d. On the older 330d it wasn't - but that is only something I was told as opposed to know 100%.

The gearbox had no issues with the extra power at all - unlike my 320d that couldn't cope. You see people with remapped 320d's mentioning clutch issues but not auto 330d owners.

I don't think DMS would map it to the levels they did unless they were totally happy it could cope. People may moan about DMS's prices but you don't see anything negative about their mapping.

Sorry, I realise that - a 335d is not like a 335i where the 2 turbos are the same size.

The 8 speed auto is what you need .


However the power delivery from x35d is super smooth and really really grin inspiring when you put foot down - in D its fine in Sport (not even Sport +) its really really great fun.

OP said E9* series ... I wasn't aware the 8 speed auto was around then ?

I didn't know the 335i had 2 the same size.
Most twins are on a v configuration engine. That's not to say it isn't though.
They are developing a triple turbo. Nor sure how that's configured

I think Crackie was talking about a manual box as the auto obviously hasn't got a clutch and think he just didn't see the previous poster had mentioned his 330d Auto.
