Remapping a 30i MSport

ProfCJJ - Do it! Remap gave me 18 BHP. Some say it's not worth it. I say it "optimised" the car. No Black spots, CLEAN progressive power and a definite additional grunt to the exhaust. It also removed the take-off delay at roundabouts/junctions (worth it alone for that!).

Interesting - more grunt sounds nice!

Where did you get your remap from please if you don't mind me asking?

Cheers

What's take off delay?

I’d assume some kind of lag whilst pulling away?

Exactly. you cant escape the CDV delay without removing it but there is an additional electronic lag which is reduced once mapped. The car becomes far more responsive on take off (I drive a manual).

...which sounds just like throttle linearity mapping as mentioned above.

How do you know the map gave you 18bhp, did you have it dyno tested before/after?

It's a generic map. Done properly you can squeeze an extra 1-2 extra bhp over the 18bhp I believe unmodified. (I read somewhere that a guy managed to squeeze 282bhp out of the N52) I didn't bother with all that. I just did it for optimisation sake with a pessimists head on not expecting much but was pleasantly surprised...but now you mention it. I'd be keen to dyno it just for the hell of it.

Just getting a post-map run isn’t going to give you an accurate picture of any increase, you need a pre-map run (preferably on the same day) to give you an idea not just of the peak figure but comparing the output the whole way through the rev range

I don't disagree but the whole point in this post was to acertain if a remap on a 30i is worth it and speaking first hand for optimisation purposes it is 100% worth it.

I had the offer of getting mine remapped cheap via Superchips so I took the offer. I'm really not fussed for the dyno before and dyno aft. Infact I wasn't overly fussed about remapping it at all for the same reasons highlighted in this post.

I am just communicating that, in my experience, it's 100% worth it to make the car more responsive, linear and remove throttle lag.

For what’s it worth, having been out on lots of Z4 runs over the 2 years two observations..

Probably a total of 500 cars on runs..

The astonishing reliability....never seen one stopped bar one with a ripped tyre carcass.

Two E85s with minor issues but were either fixed or carried on undiminished ...

Other observation

Irrespective of type/size all the cars on the road seem to keep pace with each other unless the driver doesn’t want to..

Seen one really slow E85 driver and slow 35is E89 driver..the rest kept adequate if not good if not fast speeds up!

Then it was 100% worthwhile

The removal of any 'take off delay' is worth the map alone even if you don't belive in any power gains. It's not the same as pushing the sport button (which still has a delay) and even if it had instant response the sport plus mode is still very intrusive.

Agreed. I've had some scary near misses in the past at junctions and roundabouts due to its unpredictable hesitance to take off before the map.

Now I have 100% confidence in its take off- it's pull out game is strong, lol.

Well, I have gone ahead and booked remap with Celtic Tuning, they will come in just under a month. I am aware the any BHP gain are likely to be small, but I gather that the other gains mentioned above and on other discussion fora make a remap and positive experience. Worst case, if I don't see any sort of change that I can detect I can opt to have it put back to stock and get my money back

Cheers all,
