Morning all! (morning in the UK)

I've seen on here that people have taken their cars to mechanics / dealers, and have had "tune-up" work carried out. Now in the days of carburettors and such, one could actually adjust the fuelling for the engine if they had gone waywood. But what can a mech do for our fully electronic fuel systems on the 850 besides replace rotor arms and leads and sparkplugs and decokes?

I didnt think there was much scope for tweaking fuel settings and timings.

Your thoughts?

When most people think of tune-up, it includes things like...

Spark Plugs
Spark Plug Wires
Distributor Cap and Rotor

Some folks add to the list...
Air Filter
Fuel Filter
Ignition Coil
Timing Belt, including tensioner and water pump
Serpentine Belt

Some folks add even more...
O2 Sensors
Send injectors out to be professionally cleaned (http://www.rceng.com)
Fuel Pump

Some folks add even more...
Vacuum Hoses
Intercooler Hoses
Clean Intercooler and Pipes

And I'll add even more...
Radiator and Heater Hoses
Wahler 87C/190F Thermostat
Replace Radiator Fluid
Magnetic Oil Drain Plug
Replace ATF
Hang a magnet in Power Steering Reservior to catch floating debris
Inspect Suspension and Engine Mounts

You are correct, an engine management computer controls the air fuel mixture. But, it also controls one other thing -- ignition timing.

Both of these functions can be re-programmed by companies such as http://www.ipdusa.com and http://www.rica.nl
