Ok everyone, I need a little help. I want to tune my car for 100 octane. I have tuned it myself so far. Cleaning up afr's is no problem with freelog and free crome. I have never messed with timing. just the simple retard per #. I do want to take advantage of more timing with the 100. Any help of where to start and what kind of egt readings I'm looking for along with anyh other info. I can get 100octane for less than $250 gallon 1mile from my house.

 

I would suggest renting a dyno to dial in your ignition timing.

 

I wish I had money for a dyno, but I don't Probably why I'm running free crome. Can I get away with just retarding a less per psi in the options? maybe I could just retard ignition .50 degrees/lb boost. make a little ore more and have a more consistant fuelo of much better quality? I know how to use all of crome but know very little about ignition timing. Anyone have any good links to help me learn bout timing.

 

You are not going to learn anything until you spend the money on dyno time & tune the vehicle in a controlled environment.

understood, I was hoping I could find a couple people with experience using the 100 to see what worked for them and then take it from there
