Basic Engine Ignition Timing

[MJTru]

Is it true that tuners, on a turbocharged car will advanced the timing until they get a reasonable knock level.

i was told that on N/A car this method can't be applied because on a N/A car will reach torque drop off before high knock level and on turbo cars you reach a a high knock level before you reach torque drop off.

this is a ignition map for my rb25det can anyone give me any kind of suggestions for improvements. this was increased +2 deg.

from the stock Power FC ignition map.

thanks guy's

anyone please.

Any mods etc done to it?

Heres the ignition map of a stock rb25, by no means follow this as it could cause damage to your engine as the fueling will be totaly different!

the fist map is my whole ignition map that is in settings 2 on the datalogit screen i Had add +2 deg timing to the stock map.

this is the whole map was raised by +2deg. timing

the second map was a log in 4th gear at WOT.

and the resulting data.

i use crappy 93 octane fuel ( this is not good but with a knock of no more that 15 at WOT is not to bad )

what do you guy's think.

i though that tuner keep on adding timing until they reach torque drop off or high knock levels.
