Default Enginuity: IAM jumps immediately from .8 to 1.0

'06 STI, using Enginuity 4.1 for maps and logging, stock exhaust, stage 1 tune.

I set the IAM at .8, the logs show 1.0 within 20 seconds of starting the car.

I figure this could be caused by a few things:

1. the location for setting IAM is wrong in the map editor
2. the location for logging IAM is wrong in Enginuity
3. the ECU legitimately raises IAM that quickly
4. I am an idiot

what cal id are you running (example A2ZJE11J)? Did change any table values in the 'Knock' category?

I believe it adjusts that quick on 06+. Mine will go to one in a few blocks and only a slight amount of boost

yep, that's the right cal id and all the knock values are stock.

For me, this happens while idling with no throttle blips. I don't see it move to 1, but as soon as the logger wakes up, it's already logging as 1. Maybe I should set it to 0.05 ?

That should not happen in my opinion. When you're idle it's probaby looking at 2 or 3 cells on any map.

I checked those definitions and they are correct. Do you see the .8 IAM at all or are you saying that it always shows 1.0? Remember, that your initial IAM will only take effect after a reset. Either a hard reset by disconnecting the battery or after a reflash. Other than that, it isn't used and IAM is dynamic.

factory iam is default value of 0.5.
so if it is set at 0.8, reset to 0.5.

exactly, I never see the .8
the logger only displays 1.0
Maybe it's running up that quickly? How can we be sure?

This is immediately following a reflash, but not a reset of the ECU, I guess I could try that.

thanks for the ideas guys

You can log IAM without starting the engine. Just turn the ignition to on after the reset and see what IAM is at.

Actually I didn't save the logs, just looked at the "dashboard" view immediately after starting the car. I'm going to try reflashing with a setting of .5 (but will have to wait until Friday).

veightkiller - what do you set your IAM to?
Could this be a bug or can someone confirm that this works on an '06 sti?

On some DBW cars, an ecuFlash reflash does not reset the ECU. So, if your IAM was already at 1.0, then it will still be at 1.0 after reflashing.

no kidding!?
Cool that may be the answer. I'll try it today.
Do other important settings require a reset too?

thanks x99

I have '06WRX with DBW and ecuflash does reset the ECU. I use "reset IAM" of 0.6 and after a reflash, it reads 0.6 until I drive it for a bit.

I've experienced the same. Plus my car drives like crap for the first few minutes until the ECU smartens up, it definitely is a reset.

Same here. I knocked my '06 WRX down to 0.8 and reflashed w/ Enginuity. A little -KC and crappy running, then voila a smarter ECU than I. It was back to 1.0, smooth running with a little quicker spool-up and better pull.

The ECU will reset the IAM after a flash. My car goes from .5 to 1.0 IAM after about 100 yards and the slightest amount of boost. This is perfectly normal for the 32bit ECU's, provided you have good timing maps.

I finally reset the battery and sure enough the IAM starts at .8
After hitting about 6 pounds of boost - IAM moves instantly to 1.0

Apparently some 2006 cars (STIs only?) need to have a full battery reset in order to "forget" certain values.
