I have modified my engine in the 911 2.4 T
with 86mm (2.5) JE pistons 10.0: 1 ratio of Comps, Solex camscafts, ported cylinder heads and racing headers, Weber 40 IDA 3C without vacum!
Bought a 123-Porsche-911-TUNE BIG-6-R V, but now what do I have to advance curve? Is there anyone here who has experience with this? Grateful for answers......................................
Hi Sven,
I would program the original curve which is stated in your service manual of the old distributor. Take a testdrive and try with different revs how the engine is running.
The basics is that when the engine under heavy load is pinging you need less advance in that rev area
When the engine doesn't have enough power you need more advance.
Best regards, Leen
