Quantum Remap on E89 20i
Hi guys,
Just picked up my E89 Z4 20i (2012) yesterday, looking to get a stage 1 remap done on it but i'm told it's not an easy one to do by the guys at Quantum. They tell me it's because of the way the ECU is positioned/ locked down by BMW. Been quoted £500 so wanted to hear if anyone in here has had their map?
How significant does the jump from 180 to 260bhp feel behind the wheel?
Cheers, Alex

It feels substantial
It's the torque that forces you back in the seat, it's increased by virtually 50%....
Ps, mine isn't a quantum map-I went to see Imran at evolve automotive Rob

A rolling road session before & after any remap is a good idea, it lets you see where any gains are made and how much of an improvement over standard output has been achieved

Nice one, you had any problems with it at all? MPG suffer much?

180bhp - 260bhp... crazy from a remap!
Are the brakes/gearbox/clutch ok to handle the extra strain?
If so seems a bargain at £500!

It was nearly 280bhp not 260
The engine/gearbox/clutch are identical to the 28i model, so not under any more undue strain than its design limits

I believe the 28i has different pistons and compression ratio. possibly different injectors . This explains why I will be looking at 290+ hp when getting my 28i remapped tomorrow (hopefully).Front brakes also a bit bigger on 28i. I am a bit concerned myself with this engines strength.

These guys really pushed the engine beyond its limits though lol.

They had 350 hp at the wheel when they destroyed the engine.
My local tuner will be 290 ish hp at the crank. Nothing to do with the link. The link shows that some tuners consider the n20 engine to be quite fragile.

Well, I had my JB4 on for 3 yrs and running 308 Bhp 30K+ Miles - no issues - touch wood.
However, I have avoided going down the meth injection route
