IPW would have be off too.
IDC
[IPW]*3.90625*x/1200"
IPW
="x/1000"
So IDC comes from IPW.
In evoscan under Eval will say this.
x/1000

Meaning??? You can't view or can't read it?
RPM/// PSI/// Timing/// Load/// IDC/// AFR
6500 /// 20.4899/// 12/// 217/// 92.1267/// 11.0838
This is MAX IDC I see.
@ 7100rpm its at 88% so drops little.

Man about ***** on the same besides IDC. Now I turn down a lot stuff for winter here on top end timing and my bottom end some but not a lot. same and try keep boost spikes down (I play in snow every once in awhile lol)
I know Im at 5000' but don't know if that has anything to do with it. I know if go south I will make more power so maybe you are topping them out...

See that is what I initially thought and everyone called me crazy....
As far as your altitude, doesn't your load also take into consideration altitude?
Meaning a load of 209 at 5000' is the same as a load of 209 at 300' right?
If load is the same and WBO2 readings are the same, what the hell is causing the higher IDC's?
However if altitude is considered AFTER the load, I can see how I am maxing them out...
I'm as confused as ever, but do know that larger injectors will at least allieviate the high IDC's
Oh, what is your target A/F in your tune for that rpm/load? I'm looking for disparity here....

tsitalon,
I'll go through all my other logs once I get to my tuning laptop, but here is some data for you:
2008 Evo MR - GST Boost pill, TBE, HFC, drop-in filter, FMIC
6543 / 21 psi / 225 load / 98 IDC / 11.1 AFR

Your load is the same as mine, not sure about timing, but from 98 to 103% IDC is close to me...time to buy injectors.. Do you concur?

On our dyno I usually max the injectors out around 310-315 whp on GSR's. Which is right about where the Evo 9's would max out the stock injectors as well. Keep in mind this is on 91 oct where timing is lower and AFR a little richer then 93 octane so the power is a little lower as well.
I'll get the other samples up once I get back in town, I am currently in Tahoe.

You know not going lie, I seen one guy on the other forum have this happening and thought he was crazy too lol. But that is when I went did pull with my IDC (But was de-tuned at time and still am) seen was low 90% so was not worried about it. But even when I was running more timing and everything I never log IDC but I could still control my AFR so I did not worry about it.
Correct me if Im wrong guys but if you can still control your AFR (Not say MAFR is 10.0 AAFR is 11.5) why would you worry about IDC being little over 100% then. Seems me they are doing it well still. I understand if running into lean problems and cannot get your AFR richer and your IDC is 120-130% changing them out.

Think about the ECU safe guards. If the ecu senses knock it could try to lower timing AND add fuel. Hence the problem, can't add fuel when your injectors are maxed.
It's nice to know that my tuning experience and gut feelings are to be trusted At least in this case....
