Butt tuning for S-AFC II

[Gimmegimmes]

Anyone did the above? Is it possible to do so? Risks involved? Additional equipment required?

[Elfenstar]

Not advisable at all. If you don't know what you're doing you're more than likely to kill your engine.

 

If at the very least you cant afford a road tune with a wideband O2 sensor stuck to your exhaust pipe, don't bother. If you can afford it go get it done on the dyno first then on the road to finetune the settings.
