Different sensors for plugin G4x ecu

[Yvo]

Hi,

i want to wire in the following sensors in a G4x plugin ecu in an R34GTT:

EGT, Turbo Speed and wide band lambda, can they be wired direct to the ecu or do i need some

converters?

Thanks for advice

Indeed, you will need "controlers" for each of thoses sensors thant cannot be pluged directly on a plugin ecu.

for EGT you will need an amplifier that either sends 0-5V to the ecu or through CAN

turbo speed, you could theoretically wire it directly to the ECU but the signal frequency will most likely to high for the ecu so you will need a frequency divider circuit according to Adam its fine as G4X can do 10kHz

wideband lambda will need its own controler either giving the signal through can (link can lambda) or through analog signal (aem x series for example)

G4X DI's are all capable of 10KHz, turbo speed can be connected directly.

Ok, thanks for this info, so i know now what to do

Hi, have another question,

have a stack wideband gauge with the sensor and there is a 0-5v output on it, can i use this and wire to the oxy signal in the ecu and use as wideband?

thanks for advice

Yes, wire to any analog input.

ok, thx
