for those of you who advanced timing to a radial degree.

ever notice this. run about 5 gallons of 110 octane in it. {without cats prefered} see what happens.

for those of you without knock sensors {why i don't know, but you need to be shot} do the same.

that is my final secret.

if need be, do a dyno run.

but i will say this. it does help

no detonation/knock = happier ecu = more agressive timing curves.

112 is too much and you will lose power. 110 seems right for the motor with happy timing.


just thought id share...

 

Thank you

 

 

Bryan.. ever play with Toluene?

 

hmmmm...place nearby sells race gas...might look into that...ill post how it goes

 

I tried this at the track last time. I was running consistantly 14.80's and 14.90's all day while hotlapping. I tried many different things to get my car to run faster. All my numbers were identical... 60' and trap speed.

I tried removing my cone filter with my ram air setup... didn't make a difference. Didn't help and didn't hurt. I ran 3 times with this setup.

I dumped in 2 gallons of 100 octane at the track. When I got there, my fuel light has been on for 20 miles. So, I estimate my octane rating to be around 96.

I ran 4 times with timing set at 20*. Then I ran a couple more times with timing set at 22*. Then, I bumped my timing to 25*. All this didn't make a difference at all. I kept running those consistant times.

Now, I think that my knock sensor was consistantly doing the same thing no matter where my timing was set. So, that could be the reason.

A few weeks ago, I bypassed my KS with a resistor. With the timing set at 20* with 93 octane, it knocked. So, I immediately shut the car down and put my timing at 15*. No more pinging. I drove around town like this for 2 weeks. It definitely made a difference. My low end was back. So, that leads me to believe my KS is bad.

It never occured to me to bypass my KS while I had 2 gallons of 100 octane in the tank with the timing advanced to 20*. I wish I would have tried that while I was at the track.
