I need to look into that one since I have not got this table on my vehicles. The assumption seems valid however since once TPS is above a certain voltage then it definately uses fuel map values. I need to check the condition where below TPS value and low RPM if fuel map affects injection pulsewidth and update my maphighlighting (next version) accordingly

Matt, problem is still there.
Newest nistune and still everywhere values 255.

I am interested in this issue as well.

My ECU is Type2 (Z32), and there seems to be just one enrichment table?
I'm still not 100% sure about the funtion of this table ..

Just replying to this one again since there was some concern when tables were swapped around

I keep a revision control system to track changes to all my files:

BASE_SR20_KA24_256_E
Nov 2009

TPS_ENRICHMENT_TRIGGER,&H0200,16,1,16,1,TPS volts before using fuel maps
ADD_FUEL,&H0230,16,1,16,1,Acceleration increase volume

Current

ADD_FUEL,&H0200,16,1,16,1,Acceleration increase volume
TPS_ENRICHMENT_TRIGGER,&H0230,16,1,16,1,TPS volts before using fuel maps

These two were swapped around. Add fuel jumps to last column of fuel map once TPS position has exceeded table value
