Timing Advance

[kongo127 0]

I always use 95 RON good quality gas!

How much timing advance can i get in my 1990 Corrado G60 without knocking or detonation? I have a timing light to do it, so i guess it it would be easy to set it!

Best thing to do is read the diy section of http://www.snstuning.com. Basiscally you set the timing and then keep advancing it until the pinking starts. Then back it off a bit.

 

As all cars are different, there isn't a set figure for the best performance. It is a trial and error thing.

 

Another factor is the weather, pinking is going to occur early(less advance) on a hot summers day over a cold winters one.

you can run more timing with 98ron optimax

I advanced a lot the timing! Now the car is running much better! I felt the knocking and the a retarded a bit! It worked just fine! I love the G60 driving now! And the muffler is not so noisy! No more popping when i shift down the gears! But now the MFA (in the hidden mode) shows a boost of 74 at idle (normal values should be between 84 -104 readings). And the it shows less expense fuel! What does this mean? The car is running good! What can i do for this? :?

Watch and learn! :mrgreen:

This was all about grounds!

Problem solved thanks to Henny and all the other "Corrados"! :D

Correct timing advance for a G60 (PG) engine is 6 degrees, plus or minus 1 degree.

 

In other words - anywhere between 5 and 7 degrees. Without the correct test equipment, it's a case of trial & error until you get it right. :? Best thing to do is follow H100VW's advice

 

Higher octane fuel enables more advance but the optimum setting will depend on how the car is setup & exact octane rating of the fuel used.
