the smallest amount possible, maybe 0.2 AFR in the map..

you will probably need todo at least 5 pulls before you start seeing the change.

as long as the cruise trim stays at 4% then thats ok, otherwise you will need to factor that in as well..

 

Scaling has nothing to do with the actual IDC calculation.

The calculation for IDC is:

rpm x IPW / by 1200

- Bryan

 

yeah there was always some contention on why IDC's could be greater than 100%...

 

From what I have seen, the numbers in Evoscan are way off for the IPW/IDC compared to ECUTek Deltadash. Evoscan always showed around 15% more IDC than ECUTek.

 

well IDC=RPM*IPW/1200 can't lie

Perhaps ECUTek factor in a 15% error to stop people asking questions?

 

Yeah, could be

 

Tephra,

Small changes made, ~.2 (pushed the "[" key twice on selected items 180-320 7000-8000rpm.

IDC reduced slightly from 115 to 110-112.

Logs and screenshot attached

 

Did the AFR stay the same or change? ( can't see the log right now )

- Bryan

 

Hard to say Bryan, if it changed, it didn't change much. I'll have to wait until you can see the logs.

 

Just looked. AFR looks the same if not richer.

Keep leaning out the fuel map.

- Bryan

 

[ or ]?

which is leaner? lol

just keep going until the afr starts leaning out - then report the IDC back.

its starting to sound like a bad pump

 

finally i get some reading on IDC guys, but it's weird numbers ....
i;ve put in function in evoscan for idc = 31.25*x*x/1000*x/1200
maybe i'm inserting the wrong formula ???

 

yeah thats wrong...

it should be something like [RPM]*[IPW]/1200

 

tried that didn;t work. had to use numbers instead of [RPM]*[IPW]/1200.

i'll give it another shot.

thx tephra finally u are here to save me again ! weeeeeehhhhhoooooooooo

 

Opps yeah I mean "]" leaner.......

I don't have my logs with me and can't upload them now due to company policy, but I leaned the map some more this morning. I leaned 6500-8000rpm 180-210 load cells by another 4 steps.

So now, the fuel map from 6500-8000 rpm should be roughly .6 A/F leaner..

I made one pull and plan to make a few more for you, but initial logs indicate its leaning out a bit. I actually saw 11.6 in the log this time.

I'll upload logs as soon as I get some more pulls after work, unless I get arrested for all this damn "tuning"
