q45 g50 ECU/TCU part numbers

[zspanners]

Thanks to all for your previous response.I have a JDM 1990 VH45 with ECU Nissan part number 23710 61 u02,A18-000 p00 and TCU number 31036 61 u02,A64-000 p11. Are these numbers correct for this engine / year and are they the same as US spec.Could anyone tell me the 1994 ECU/TCU numbers and what the spacific differances are.( I belive the 94 TCU has 1 st gear start ,is this the only differance ?).

Thanks Ashley.

To match the earlier gear ratios, you want a US late 1993 TCU. Unfortunately, this was an abbreviated run so there are not may out there.After 1993, first and second gears are shorter (lower numerical ratio).
