My IAM will not move from 1
I've been logging my car and my IAM will not move from 1. I've always had this problem and I'm not sure why. As far as I can tell I am not getting any knock, my knock correction is always right up by 9 at WOT. Never dips below 5 in probably 20 logs over the past few weeks. Anyone know what's up?
Thanks!

its supposed to be on 1 (100%)
if you reset it it will drop to 0.5 (50%) I think you thinking in 16bit ecu terms and looking for a 16(100%) you got a 32 bit ecu and 1 is the best it gets |

yes, 1 = best for 32bit (04+sti & 06+wrx)

Another IAM question...I have increased my IAM to 26, due to use of high octane fuel. Do you think is a good idea if no knock is present? Or are other implications that can damage my engine?

not to be a dick but you have zero information in your profile and you've provided zero information to us about your car...so it's going to be rather difficult to help you.

Without more information it is hard to tell what you are doing. BUT there is such as thing as too much timing, even if you don't get knock it will kill your rod bearings if such a case was present. What octane fuel are you running by the way? |

Sorry about the lack of information.
No. I have change the IAM using enginuity from 16 to 26. Also change wastegate and turbo maps to give 0.69 bar instead of 1.2 bar to put less pressure on fuel. Here is my log (please, use download as... to prevent explorer exe the file.) I am using a 2002 JDM STI. My question is if this IAM increase have any other effect more than detonation or misfire. |

I am running a home made fuel using methanol, toluene, a bit of heptane and a bit of lubricating motor oil . Also I use to mix it with a little of regular gas, but is difficult to know the octane rating of the mix. Probably 108 or higher.

Oh are you getting boost spikes at all? you may not see knock in the logs but you should see some timing being pulled. Also if you have a wideband post the logs showing ign timing and also your afrs so we could best evaluate the problem. |

Yeah someone answered my problem earlier, I have a 32 bit ecu so the max my IAM can go is 1! I've only logged on an 04 wrx before this so I thought 16 was the highest for my car as well.
I'm not getting any spikes, the boost is progressive and builds up to 21 and then tapers to 16 or so. My wideband is not working, I can't get the stupid serial to USB cable to work on my laptop. I installed the drivers but it's not recognizing it! Quote:
