US STi oem. I am 99.9% certain that my CR is 8.2:1.
In OLF, if AFR's are very near target and boost is not excessive, should modified ignition be exceeding that which the ECU wants to run? Again, I imagine this is a loaded question, with regards to Jon's post. I'm saying if you're without the means to validate maximum brake torque (in other words, lacking a dyno) and are just trying to normalize timing to a solid but safe level, is the table that the ECU is using a good standard?
I just got back from trying to tune, and I'll admit that my ignition advance multiplier is still at 8 since I reset my ECU. I know that when I get it up to 16, the ignition advance that the ECU will want to run will vary from what I saw tonight; it was just a question that occured to me.
