Please send some install pictures. Check the underboard settings are matching the above drawing just in case.

Is this wiring diagram applicable to the 2011+ N18 engine?

I looked into this briefly. The N18 DME is still made by Siemens I cannot verify the the pin out compatibility.

N14 Engine - N14B16AC (171hp / 177 ft-lbs)
* infinitely variable single VANOS (intake only)
* Siemens DME MED17.2 engine management

N18 Engine - N18B16M0 (181hp / 191 ft-lbs)
* infinitely variable double VANOS
* map-controlled oil pump
* variable valve timing (Valvetronic) with 3-phase servomotor and integrated eccentric shaft sensor
* composite camshaft construction
* new piston design
* Siemens DME MEVD17.2.2

Hi Richard,

Excuse me for being the first post I've ever made on this forum, but I've had my HFS-4 installed for about 3 weeks now and I wanted to know if I have this set up correctly...

I have a '10 MINI Cooper S and currently I'm running without any type of restrictor and a 0.7mm jet. The injectors in in a R56-S is rated at 380cc. I'm also running a 50w/50m. Have I set up my system right?

Here's an image of my board...

Welcome to the forum.

I think you should put in the 0.7mm restrictor.

The setting looks good. if you have any slight mis-fire at high RPM, please up your meth ratio.

Can you tell me where are you putting the jet?

Thanks Richard. I have the jet located just after the MAP sensor. I wanted to place it where Jeff Howerton had placed it in his guide on the hard plastic, but knew it was going to take a bit more work to get the hole set up and it was easier access to place the jet.

I was running a 50m/50w, but now trying a 70m/30w mix.

What would cause the mis-fire at higher RPMs?
