2005 US RSX Type S with K20Z1 engine - ECU part number PRB-A13
2006 US RSX Type S with K20Z1 engine - ECU part number PRB-A14

Well that is essentiall about everything I know. WHat else are you looking for...just K-series?

2002-2004 RSX (Base 5 speed) (PND -A0# ECU)
2002-2004 RSX (Type S) (PRB ECU)
2005-2006 RSX (manual transmission with adapter harness and modified 02-04 ecu)

TSX ECU with numbers RBB-A01, RBB-A02, RBB-A51, RBB-A52, RBB-A53, and RBB-A54

Now I have to find what those numbers go to, goal is to create the largest ECU guide for hondas, from the birth of the B series up.

I believe OBD1 ZC is P29

Wasn't there a PG6 in 1gen OBD0 tegs too?

PT3 = 89-93 Accord 5 speed
PY3 = 91-93 Acura Legend

Not positive......someone verify

Del sol -P1Z

96 Accord V6 - P0G
