hi fellas,

i did a search on this, but my problem with the PFC is slightly different than the answer I found...

look, i have a SI RB25 and run a PFC pro on it, and it has some issues with it memory... it turns on well, and the engine is also running smooth... i am running 550cc with z32 AFM and put in the figures (67% & 80mm) and the PFC memorized them... now, since the PFC is running way to much ignition in idle, i edit the ign maps so that it runs smoothly at 850rpm and knock levels stay nicely below 30...

now, when i turn the engine off, take out my key, and then turn it back on again, the newly entered values in the ign. map are back to the original settings, but the injector and AFM have not changed back to stock (still 67% and 80mm) ... so wtf is wrong? pin 58 has constant 12v from the battery, and there are 3 more 12v+ which are switch over relais (when ignition is on), and they also provide electricty to the PFC when key is in ignition position...

but why wont it remember the ign. changes??? also if i raise/lower the values for Rev limit/launch control, it resets them back to factory when I take the power away??

please help...

thx,

nico
