Default ID injector values

Trying to dial in some new injectors and I'm just not sure if I have all the new values plugged in. The spreadsheet from ID shows tables I can't find in Accesstuner. Not sure if the tables are called something different.....or maybe a different spot.....or maybe 16 bit doesn't have them, only 32?

Info:
02/03 wrx 16 bit ecu
ID1050x injectors

I have the scale and latency values plugged in, but can't find the tables the spreadsheet calls:
-"Fuel Injector Trim (small IPW)"
-"Fuel Injector Trim (Max. Small IPW)"
I have screen shots of the tables from the spreadsheet below, and also a link to the spreadsheet.

You need to go on speed density mode to get that option. You can tune maf through there so you don't have to deal with the maf limitations.

Awesome, thank you. Was looking for that table all week.

I knew about SD/maf hybrid mode, but not the MAF only mode. Gonna have to look into that more because the additional tables seem very useful.

Default ID injector values

The "small ipw" table was very helpful for idle. Wasn't too bad switching my map to the SD maf-mode, most of the tables are the same or only slight differences. Thanks!

Just have another related question:

For larger injectors, ID1050's in my case, I need to adjust pretty much all fueling tables with pulse width values, right? Initial tip out, overrun, cranking, fuel pump duty cycle pulse width, etc??

So...since the stock wrx injectors were 440cc and these are 1050cc, would reducing those tables by 50% be a good place to start? Just seems excessive.

I've already reduced the overrun initial value by like ~50% to help with the gunshots erupting from the exhaust....but haven't gotten around to the rest too much yet. I definitely think the fuel pump duty cycle "high" pulse width values need to be lowered. Takes a while for it to switch over from mid to high now.

Am I on the right track, or way off here?

50% is ball park and a good starting point and if you want you can probably reduce it less on the cranking. Important tables to touch upon are the cranking tables, tip-in enrichment, Closed/Open Loop Transition with Delay (Min. Base Pulse Width) and etc. Fuel pump you will have to play with just depends on the pump being run. Also set your afr learning#1 to never learn on the last range. You seem to have the grasp of it just experiment and see what works best.
