probably best to ask the person you are gonna use to tune it.

depends on the mods you have as to how long it will take them to clean up the AFR's

think most places are like $100 -$150 an hour for dyno time..

so budget at least 2 hours minimum id say

safc's are pretty simple to tune, expect far less than a proper computer (fuel & timing eg. powerfc etc.). Basically what they will do is run it up on the dyno (or road tune), and tune the fuel map. that's basically all the safc can do (apart from removing speed/rev limiters etc.). You'll probably get a bit more power, but the main advantage is it ensures you aren't running too lean, which can save you from blowing an engine! If you have an aftermarket turbo, i'd suggest at the very least safc. Though, stock ecu remap is far better.

it would take me 1-2 hours to tune one (i've never done it before but it's like an 8x8 map for fuel only or something, so how hard can it be...), i've never seen a quote by an actual workshop so that could vary.

Why don't you just ring a few tuning workshops in your area??

    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
