I have a Link G4 Extreme wired into a JZX100 running a 2JZGE+T forged engine. I have used the coil method to up the tacho voltage for the tacho without an issue, and can drive the speedo using an IGN output as the dash sweep when switch on works. The issue I am having is that I cannot read the left front ABS sensor to get a speed into the ecu to be able to output. I first wired the wheel speed signal into digital input 6 with sensor signal and sensor ground. this was unsecuessful with or without the pullup resister. I have now tried wiring the sensor to +8v out with a grounding resister of 1.15kohm which gives be a sine signal 1.6-1.8v which i can see increases frequency with speed but the ecu will not read anything. do i need to increase the ground resistor to up the voltage or will this not read anything into the g4? Please someone help me get a wheel speed signal in the ecu. Many Thanks Brad =)

After a little further reading would it be possible to input and output all signals as per the inline 6 by using the following: Trig1 - Crank Trig2 - RHbank Exhaust cam Digital1 - RHbank Intake cam Digital2 - LHbank Exhaust cam Digital3 - LHbank Intake cam Then Use Analog load inputs 1&3 for MAP and TPS Aux 2 RHbank Intake advance solenoid Aux 4 RHbank Intake retard solenoid Aux 5 RHbank Exhaust advance solenoid Aux 6 RHbank Exhaust retard solenoid Aux 7 LHbank Intake advance solenoid Aux 8 LHbank Intake retard solenoid Aux 9 LHbank Exhaust advance solenoid Aux 10 LHbank Exhaust retard solenoid This still leaves Idle control via AUX 1 and all 8 channels of injectors and ignition through 2 4 channel amplifiers one for each bank, and Analog inputs for 0-5V map switching through a simple switch. If this configuration would work will the CAS 12v sensor power be able to cope with 4 CAS powers? I will complete a wiring diagram after I get the wiring pinouts for the S62 engine, so any feedback anyone can provide would be a huge help! Many Thanks Brad =)

Hi there, I have been reading through the forums looking for information on the Link ECU's as I have a G3 ecu in a competition drift car however I am now changing engine to the BMW M5 V8 S62 engine which has dual vanos on each bank. I have the wiring diagram for the dual vanos on the S54 M6 inline 6 engine using Trig 1 for Crank sensor, Trig 2 for exhaust cam angle and digital input 1 for intake cam position, then 4 aux out signals to switch the soilenoids to ground to activate. My question is wether it would be possible to have an additional 2 digital inputs on the G3 ecu, and if it would be possible to change the AUX outputs from a switch to ground to a positive output of either 6 or 12v so that I could build a simple logic board to use one aux output to control 2 relays based on if the input signal is 6 or 12v thus allowing me to control 8 soilenoids through 4 aux chanels? if this is not possible is there any way of combining the intake cams and exhaust cams for both sides and linking the soilenoids so that both soilenoids are controlled via a drift of either left or right bank cam sensor and use the vanos as a single RPM switching point to go from full retard on both banks to full advance and hold? Would it be possible to find out how the Vanos control is performed? is it just switched to ground and hold? Many Thanks and apologies for the long first question. Brad =) g09.pdf
