with stock timing, and 87 gas.. i sprayed a 100 wet shot with no problems at all. I got the diablosport for christmas, and since then, have not sprayed. I installed the "diablo tune" and ALSO increased timing to +9 (its measured differently then degrees, perhaps %). I ran 93 gas with this tune with no problems. If i wanted to spray again tonight, what should i retard the timing to, without removing the "diablo tune" which would f**k up my check engine light, traction control delete, and fuel curves. Shoudl i set it back to 0? or would that still be higher than stock due to the "diablo tune" Keep in mind that im now running 93 gas instead of 87 (which i sprayed with stock timing with no problems.) i dont want to damage my engine.

 

i i think its 1.5 degrees per 50 shot is a good number to go buy.

 

so lets say 3 degrees... anyone know what that calculates to on the diablo tune... im at 9 now and it goes down to 0 then to -10

 

[100/300]*3=.833%thats what i come up with

 

you ran 87 octane with a 100 shot?

 

yea

 

so basically ur saying retard it 8%?

 

u never had a problem running regular gas?? i thought nitrous required higher octane and you have to put 93 in.

 

nope never had any problems

 

You should always run the highest octane you can when spraying, just because he got away with running 87 does not mean you will. He might have been running on the edge of disaster, and not have even known it.
