1g timing vs 2g 95 timing????

[Turbo Monk3y]

Was it the 1g cars that had a higher timing curve???(Keep in mind these questions are for cars with 5*BTDC) For example on a WOT run many 1g guys report 18-22 timing advance.. And well I have a 2g 95 and a 1g 6bolt motor.. I remember reading somewhere a long long time ago that 95s had a weak timing curve.. Is this due to the ECU?? or what controls timing? The reason im asking this is because i have my car set to 5 BTDC and when i make a WOT run with 0 Knock the higest timing i get is 16. I CAN use my dsmlink to raise the timing but i just wanted to know if 16 timing advance is normal for a 95 ecu with a 6bolt? Right now i have taken out 2 degrees of timing from 5K rpm to 8K rpm so the highest my timing reaches is 14 this is to compensate for the 22-24 psi i run on pump.. ALso one more question would i gain more power by running 24psi and taking out 2 degrees timing up top making it 14 with a more lean curve on fuel, Or would i make more with 24Psi on say 18 timing advance with a richer fuel curve up top to keep from knocking????? Let me know Im curious as to get a little more power on pump..

I believe the 1G spark curve is more aggressive than the 2G. It probably would be considerring the compression change (up to 8.5 from 7.8).

You will get more power from spark advance than AFR. You will get more power from boost than spark if you are in the efficient range of the intake system (turbo, IC, intake, etc.). Fuel really doesn't give that much power in most cases unless the AFR curve is extremely rich (or lean).

95 Ecu's on the peak timing curve, meaning flowing more than 2.1g/rev of airflow, should reach 16* at peak, so yes you are fine. The ability to have LOWER timing IMO is much better. Lower timing and higher boost creates more power than higher timing and less boost. When you see 16g powered cars flowing 22-23psi on pump gas, I believe youll agree that having a higher timing curve isnt always better.
