To bump an old thread. My 92 SVX LSL is a 6/91 build. It has the ROM chip, no tan resistor and the noise suppressor is absent. The loop is there, just not the black bit.
That sucks since mine has a bit of a hesitation when pulling away from a dead stop. It feels like the ECU pulls timing (quite a bit at that) for s split second. I may have to buy the ECUtune kit anyway in order to run 87oct. No sense in running premium since I drive like a granny anyway.
