Ok to repeat heres what I Have:
GTiR Base ROM:
For the ~440cc Z32 K value I took the DE 370cc K value: 53E3(hex) or 21475(dec)
To convert to Z32 Maf: 21475(dec) * 2.2 = 47245(dec) or B88E(hex)
To convert to 4bar (~437cc): 47245(dec) * (380/437) = 41083(dec) or A07B(hex)
Plug this value of A07B into the GTiR Rom, and then Loaded the Z32 VG Maps. Since ~437cc is roughly equal to 440cc this should work, with the possibility of some minor tweaking with fuel pressure.
Now we need to remap the TP axis (with the U12 axis scale) for the fuel and ignition timing maps. I read the values from the stock U12 ECU and multiplied them by (380/437) = ~.87. I replaced each of the TP axis values with this calculated value.
Then I just need to go thru the Fuel and Ignition timing maps and make them a bit more safe, especialy since I'm running a 9.5 DE engine. These maps should have been tuned for the 8.3:1 CR of the GTiR block.
Awesome, really appreciate the walk thru Calum.
One last question, from reading devins HOWTO on ztechz I understand (or think I do) the knock maps. For the timing map, any value over 128 or h80 is considered part of the knock map. A timing value of 0 also starts at this value.
My question is, for timing these knock maps are along the max edge of the TP scale. So if there is NO knock detected what does the ECU read at these points, the last value just to the left of the knock maps?
The fuel maps appears to be sort of opposite. The knock maps are located on the low end of the TP scale. So under WOT/high load will it just ignore the fuel knock maps?
I couldn't really find much information on these maps, seems as *** most just take em out.
