Thanks for the Digifant link.

I read once before I think either here or on Vortex that you can swap a MAF sensor from similar era BMW's (with some modification) and it helps to increase power?
Any advise or opinion on this?
Is it it worth it for the power gain? (If any)
There would be heaps of BMW's around in the wreckers.

Absolutely spot on. The 535i series uses the same Air MASS Meter (not air flow meter) component which provides a voltage signal to your ECU . The diameter of the AMM intake and outlet is greater in the 535 therefore it allows more air into the engine. However because the AMM from the bmw is driving a 6 cylinder not a 1.8l 8v the spring tension in the AMM needs to be adjusted. You also need hosing to connect it to the throttle body and look into 1.5bar FPR.That in itself is alot of work not to mention the tuning!!

As for the revving I would...
1. Check vacuum lines - especially the ones connected to the FPR (Brass thing found on the end of the fuel rail - usually left hand side tucked under the throttle body.
2. Coolant temp sensor.
3. CO2 screw (brass screw on front left of throttle body pointing out horizontally)
4. Dizzy and lead to the coilpack


Good luck!! Let us know how you go.

Hi Gavin,

what can you do to make an RV engine a proper GTi?

The exhaust manifold and downpipe are total rubbish. That's where you should start.
