Jim Wolf's socketed ECUs are the same for years 1990 -1992. Their 1993+ ECUs are different. However, I've read that the ASH-Spec socketed ECU is the same for 1990-1994. We are assuming equal comparison: 5 sp, Fed emission, single PoP, 370 inj., 91 octane. Will a upgraded Ash 1993,1994 ECU run correctly in a 90-92 twinturbo ?
