Nissan 64pin ECU design done for a client, supports the CG10 through to the SR20DET by adjusting a couple of link wires to suit the engines ever so slightly different pinouts, VR conditioner option in case they went to crank VR setup.
onboard wideband.
oil & fuel temp inputs with adjustable bias.
oil & fuel pressure inputs.
fuel tank level input with adjustable.
spare output on the diagnostics plug.
spare input to switch tables on the diagnostics plug.
EML control (sync warning / shift light options)

speeduino or EPIC-EFI firmware using the STM32F4-Mega100

Speeduino (arduino mega 2560 MCU) or EPIC EFI (STM32F767GT6 MCU) hybrid board for the nissan 64pin ecu range in the making, CG10DE through to the SR20DET supported :-)

Created a copy of the little black box board last night to be igntion only dual channel (with IGBT option) and wideband controller for 2cyl bikes with dumb coils and cars running a single dumb coil with a distributor (V6/V8), or you can use a wasted spark smart coil without the IGBT's fitted for 4 cylinder engines.

My own version of the speeduino 0.3 but a fully loaded version with IO never featured on a speeduino board so far by default.

left top we have outputs for Boost, 2x Idle, VVT, 2x grounds, Injectors 1-4.

left bottom we have 1-4 Ignition, 2x grounds, 4 wire idle (optional 4x IO if needed).

bottom left vwe have Tacho, Pump, Fan1, Fan2, Spare 1 and Spare 2, 2x grounds and 2x 5v.

bottom right we have 3x grounds, 2x 5v, clutch, D21, Knock, Fuel flex, Idle up input.

right bottom we have 2x 5v, VR1, VR2, VR3 (VR VSS), 2x grounds.

right top we have IAT, CLT, TPS, MAP, O2, Fuel level, fuel temp, fuel pressure, oil pressure, oil temp, all temp inputs and fuel level input have variable bias resistors to suit all types of sensors.

top right we have 6 pins for an LSU 4.9 wideband, 1x wideband 12v input, 2x grounds and 12v main power input.

onboard BT 4pin port for direct fitment of the HC-05 BT module, selectable serial 0 or serial 3 jumpers.

spring loaded terminals or screw type can be used, fits the clear lidded Hammod RP1275BFC case that measures 186 x 146 x 55mm and cable entry gland can fit bottom centre of the board.

Well done Very catalog for selling poorly assembled electric trikes 👌

For a 3 month old item that’s failed you will be getting a nice complaint!

Wondered why it had stopped charging, control module stuck on with no bolts or screws to hold it so it’s pulled the charging wire off when it fell off

Time to fix it and mount the controller properly and secure the wires correctly
