Many Nissans can use our tools to reprogram their factory ECUs.
Types of Nissan Computer
Trivially chippable Nissans fall into several categories:
28 Pin EPROM (VG30DETT 300ZX Twin turbo, KA24E 240SX, RB26DETT R32 Skyline GTR, …) – If you see a 28 pin EPROM inside the ECU, this is your application. Ostrich 2.0 works in almost all cases, but many of these applications will require a SocketBooster.
20×2 ROM Board “S13” (SR20DET Silvia/240, SR20DE Sentra, SR20DET GTiR, etc.) If you see a spot on the edge of the circuit board with two rows of 20 pins, this is probably the application. (also see below S14a) The Nissan 20×2 Adapter board is intended for this generation. Two Ostrich emulators can be used for realtime emulation.
20×2 ROM Board “S14a” (SR20DET “black top” VVTI, 95-97 “B14” Sentra, etc.) If you see a spot on the edge of the circuit board with two rows of 20 pins, this is probably the application. (also see above S13) These are not supported at this time. Future hardware may add support.
40×1 ROM Board (Late model sentra, 240?) If you see a single, extremely long row of pins that are very closely spaced together, this is your application. These are not supported at this time. Future hardware may add support.
Many Nissan ECUs are not trivially chippable (RB25 Neo, R33 Skyline, R34 Skyline, 350Z, …)
TunerPro RT has definitions for most S13/B13 platforms.
925style ROM editor supports most JDM ECUs. I’ve used sucessfully with S13 SR20DET and R32 GTR Skyline. It isn’t officially available anymore but you can find it easily with google.
CROME is compatible with certain Nissan ROMs, particularly those used in S13 based vehicles.
