  1. MAF change in Nistune Warning: Noob hackery I have swapped out stock MAFs for Nismo MAFs, then used the Nistune Change MAF function to update from BNR32 RB26DETT (290 HP) to Z32 VG30DETT (500 HP). This causes a slight change in profile of the VQ map and changes K from 233 to 401, which is same ratio as 290 to 500. If I now try to start the car its too lean (leaner than my WB can read). As an ugly hack to get it to idle, i changed K from 401 to 880, and it idled at 17:1 and if i take it to 1100 it idles at 14:1. If I then drive its really rich off idle eg 10:1 as would be expected. Now i want to see if normal driving is ok at K=401, so i need to richen up the idle. I've changed the bottom left cells of the fuel map (all originally around 0). I tried 3, 6, 12, 24, 48, uploading the maps to ECU after each change, but the idle stays way too rich. No idea where to go from here...
  2. Hey all! going from pink label to r35 maf when my stagea goes for a tune. Running nistune. just wondering if i should go through the extra effort of wiring the maf into cooler piping or put it in the 4 inch intake? Car will have no BOV and max flutter so not sure if thatll affect it. expanding on that! If in either location where in the piping should the sensor go?
