944meister

Through some research I have found a few alternative fuel injectors for the 1991 944S2, which use a high impedence injector compared to the low impedence of the 89'-90' model years.
1991 944S2:
Bosch# 0 280 155 003 - 15.1 ohms 264cc @ 3bar

VW Corrado G60:
Bosch part# 0 280 150 905 - 15.8 ohms 264cc @ 3bar

1995 Ferrari 355 3.5l V8:
GB Part#: 852-12216

The Ferrari 355 seems to use the exact same Bosch injector as the 1991 S2, Bosch# 0 280 155 003. I have provided the correct 355 GB remanufactured part#, because GB does not distinguish between the 89'-90' and 91' S2 model years. i will do a little more research to varify that the 355 injectors are the same.

Interesting. I have had to run high FP to get a decent A/F ratio and just recently learned the difference between the '89-90 and '91 FI's. Need to look tonight and see what combo I am running.
I also believe I have an early and late DME so not sure how that woudl impact the situation as well.
