Potless Remap

[GBZ4]

Having had it pointed out that I'm a couple of cylinders adrift would a remap return me a crum of credibility or would I still be seen as deficient in the pot department?

If yes, does the collective, both those with all faculties and those with deficiencies have any suggestions as to what would be best.

I believe there are big gains for you - turbo's are just waiting it be remapped and the 1.8i E89 is perfect for big gains in BHP :evil: I know Rob (Smartbear) has considered it, he can tell you more.

An extra 100bhp (or even more) is but a change of software away gbz4, ignore the naysayers as they will surely be in your wake :wink:

grab MHD, pay for the license(s) and you can have your car mapped within the next hour using the most up to date maps available (I'd use the 7.1 95-98 ron map)

What gains do these maps bring to the 18i out of interest?

oh yeah, good point it's not an n54, ignore me im hugely hungover

I'll go off and see if MHD supports the 4 pot and report back dreckly

 

[R.E92]

MHD only works on the N54 and N55 engines. Probably not going to be supporting a 4 cylinder engine in the near future as I expect the next development will be for the B58 engine. Good news for future Z5 owners I suppose.

 

[Maniac]

Totally potless if you ask me (see what I did there?)

 

[buzyg]

Enjoy it as it is.

I think a remap is always good if done well.

Interesting choice of cars though. Given the choice between a 335d and an 18i for the weekend I would be in the 335d! My pick would have been a 320d for the daily and a 35i for the weekend. Or just daily the 35i like I currently do and stop at every petrol station on the way

I'm sorry but I don't see how you'll get 100bhp from a map. Nearly everywhere I've looked states the 18i is good for around 200bhp once mapped, the 20i will go to 240bhp and the 28i will go to a smidge over 300bhp.

These can't be the same engines. There must be something other than the tune that makes it possible to get over 300bhp out of the 28i mapped but not the 20i.

Engines are identical across the range Steve, turbo is also the same-100bhp is a conservative estimate-

Others offer even more (superchips for example)

Fair enough, I wouldn't question Evolve to be fair but why do they offer a stage 1 map for the 28i which takes it to 300bhp then?

If they're exactly the same why does every company quote different stage 1 figures for the 18i / 20i / 28i?

On another note, 100bhp from a remap is definitely worth it!

I think the dme is slightly less sophisticated on the 18i which would explain the lower potential, as you say though Steve it's a massive hike in power from just a software change

Thank you all for the input, I have looked at Evolve and if the dyno print is to be believed then a boost of 60% is remarkable. But I'm really a sceptic and a more modest 30% is more likely and I guess that would do fine.

But then again Superchips are bandying big increases around too. These guys are £200 cheaper, is there a reason?

:dizzy:

With superchips you don't get before/after dyno runs, because of this you don't really know what you're getting.
They also charge £50 to reinstall your map if it's wiped off by a dealer, Evolve will do this free of charge.
I've read evolve maps are conservative claims, some of the other companies claim as much as they like without it being substantiated. That's how I see it anyway

They don't claim 300bhp, they claim an additional 40bhp & if the car makes as much as bmw say (245bhp) their map would take this to 285bhp

Yes sorry, it was DMS who have quoted "over 300bhp" to me.

I'm not fussed about the headline figure, I just want it to be as driveable as standard and work with the auto box.

I have always respected Evolve but DMS also get very good reviews.

I've had remaps from AMD and Revo in the past on VAG 20VT engines and been really impressed, but I am stalling with the Z4 as it is plenty quick enough, but more is always nice.

Plus, the way the boost comes in its hard to imagine more boost (which is ultimately how they're upping the power!).
