JDM VH41de ECU reprogram???

[nissman77]

Hi all. Can anyone tell me if its possible to re program JDM VH41de ecu ?? I am about to run one with factory ecu and 300zx 5 speed box and am sure it would benefit from re tune.

hey mate. You are better off sending your ecu away and getting one of the NICO ecu's which now come with 3 selectable maps all pre-programmed. Its pretty cheap for what you get! and the HP gains are relatively huge!

Actually the current offering for the NICO ECU's is 1-way, 2-way, 4-way, and 8-way switchers. Only for the 90-93 year 8-bit ECU's. Still not messing with the 94-95 16-bit ECU's...Yet.

Pull the cover off the ECU and post or email me a photo if it. Curious to take a look but I'm pretty sure it's OBDII and not doable using the current methods. I would like to delve into the OBDII models if I can gather up the right info.

Im pretty sure its from an early 90s y32 Cima. Apparently Nistune do a board to make it real time programable. Anyone heard much about Nistune? Sounds like the go for engines with big mods.

Very interested, as I've got same engine and ECU.

nissman77 do you have maybe any pinout for it?

[nissman77]

hey i used the wiring pinouts for the early vh45de and all the important wires are the same. looks like the connectors are the same between early vh41 and vh45 ecu
