rb20det rom, injectors and questions

[Vkoslak]

So I recently bought some of these:http://www.witchhunter.com/flo...0.jpg

545cc at 3bar, which should be what the nismo fpr is with vacuum tube off.

I also got the z32 mafs to go with it. And then a rom chip came in the same package supposedly already tuned to run these injectors and the maf in a rb20det.

Here is the rom if any one is interested:http://www.vkoslak.net/ecuroms...2.bin

I got it from the chip by plugging in the ecu with the new rom, putting the key to the on position and hooking up the nissan datascan to the consult port.

I have been looking at live edit and comparing stock values, calculated values and the values on the included rom. I don't think the rom values are set properly to run z32mafs and 545cc, the tune looks like 570cc injectors would be a better match, but then it limits the injector max to 65. The stock tune is at 128. Live edit changes these values to 255 if you change the MAFS.

Anybody got any ideas on this rom tune? I've been trying to follow the advice available at ztechz but this rom just doesn't seem quite right.

I have a spare programable rom and my rom burner should be here next week. In the mean time I need to locate rx7 injector plug harness to run these things.

I'm trying to find a good tune that will run the car (until I can get it to be dyno tuned) with these injectors and a z32mafs. If at all possible with a hks gt2530 running 16psi.

Thanks in advance for any advice you guys can give me.
