Advance Mutiplier resetting on restart?

[feldy]

So I got a new flash in the other day from fa20club. It had some fixes in it from Ecutek. We were unsure what the fixes were.

Also now I have been noticing the Advance multiplier is resetting to .7 on every restart of the car and it builds it self up back to 1 as I drive the car. But it just resets when I shut the car off. I don't remember this happening before. Am I nuts?

[King Tut]

That does seem nuts. It should only reset to 1 after a reflash and then should settle to whatever it needs to be and change in small increments over time as it needs to. Perhaps they found a different way of calculating it or a different location in the ROM to datalog it. @FA20Club.com

The default IAM setting on the stock ROM is 0.70. Looks like it is unchanged with that flash.

[feldy]

It goes back up to 1 over a few miles of beating on the car. But when the car shuts off it restarts at .7

I did get logs last night to @FA20Club.com and this morning as well showing the Value reset.

Wonder if Ecutek botched the patch.

My car has done this since day 1 as well. It will keep the learned multiplier for a few mi utes after I key off but if it sits too long (couple hours) it will always reset to the initial IAM value set in the rom, be it 1.0 or .7 or whatever I set it too. The fact that it is working its way up to 1 is good though.

Glad Im not the only one seeing this behaviour. My original to. ID was ZA1JA00C


Ohh and I have never used ecuwreck, only brzedit and open flash. Seems very odd to me because IAM is long term k rock control. If you live in an area with crappy gas its gonna have to knock before the I am works down every day....

Hmm... I don't know why I never noticed this before. maybe since I normally do my logging in the afternoon after the car has been driven on and warmed up.
Hey @mad_sb can you pm me your email. I would like to send you some logs from last night and this morning and see what you think. I have the same logs off to Tony to check out. But dudes so damn busy making front pipes for me and turbos and what not for all you ballers. hehe He needs a clone.

Interesting. I have never seen that happen on my ROM, but now I will check it to verify.

[feldy]

Yea its weird I have had a flash on my car since March and I don't ever remember it doing that. I guess I can reflash to a previous tune and see if that does it as well.

[feldy]

just went and looked at my old logs... nothing to see here. it seems like its been this way the entire time at least for me since march.

[mad_sb]

Do you happen to have any logs of the car before it was flashed? I have a hard time believing this is the factory behaviour.. Perhaps if it works its way down low enough it will stick or switch to a lower initial value..

[feldy]

No. And even so the IAM values are hidden from what I can gather on the stock rom are they not?

I have logs from a stock flash but nothing before I flashed in march .

I sent tony a email saying never mind after seeing all my old logs did the same thing. Hope he still takes a look at it and let me know whats up.

Nahh, brzedit logger can read iam on an unflashed car i believe.. Just thinking it could possibly be something that both ecutek and brzedit change in the roms they distribute as "stock" Then again i think all brzedit does is embed your username in the header area of the rom so.....

Did you ever check to see if this happening to you? I'm wondering if all the ecutek flashes do this? I haven't heard back from Tony @FA20Club.com about it yet. So I want to assume this is normal? maybe from a safey issue? Start it at .7 and if I have bad gas no harm no foul? but if the gas is good and the car likes what it seems then it raises timing back up?

[DSTL]

Not sure the cause but on Visconti tunes I've always had both min and max of 1 except when I had a bad fuel. Never reset to .7 though, always starts at 1. I have seen it as low as .52 on bad gas.
