IIRC, my '89 Carrera manual says use 91 Pump Octane.



The FQS -Fuel Quality Switch is a small rotary switch inside the DME box, accessible via a hole in the metal DME box (about 1/2 inch diameter). If one hasn't open the box up to see it, be careful. Don't go sticking stuff into the hole or you'll be just like the kid who let his buddy drill into his ZX6 ECU.

A small tool (triangular tip) can be made from a long golf tee to insert and make adjustments.

Here are the settings:

SwitchPosition/Fuel Correction/Ignition Correction
0/0/0
1/+3.1%/0
2/+6.3%/0
3/-3.9%/0
4/0/-2.79°
5/+3.1%/-2.79°
6/+6.3%/-2.79°
7/-3.9%/-2.79°
