RX-8 Cluster with working EPS without ABS/DSC

[Wastgate323]

Hello

I'm new to LINK ECU. Before i only use MS ECU's.
But for my new Project (RX8 Track Car) i use a more professional ECU. I have read alot about the CAN Protocol from the RX8 here in the forum. The Dashboard has right now only ABS ans EPS  error codes. The rest has a Signal from the ECU (Engine, Coolant, Oil, Battery)

I have use the information from Adamw MAP. i try to test the ECT. but the Gauge does not work. (I use a Fury X ECU)
I had simulate a temperature above 95 degrees. But no reaction.

 

 

Thank you for your efforts

Attach your tune and I will take a look.  Much of the CAN scaling and enumerations has changed from G4+, so it will likely need some changes to work in G4X.

I'm finally back in the workshop.

i have all wired up. Power Steering and ABS without DSC. Any device has Power supply.

but the controllight are still on. (ABS, Handbrake and EPS)

Thank you for your help.

 

kind regards

I have also a problem with wheel speed sensors. I can not add parameters lf, rf, lr and rr wheelspeed that receive to ecu.

Update your firmware, then load this map.  The CAN Aux labels on stream 3 arent displaying correctly in this one but I think it will with current firmware.

Thank you so much Adamw. The Engine is finally run and the Cluster and EPS works. ABS llight is also off, but i can't test it right now if it really works

The Car was finally on the Dyno. Everything works betwenn the ECU and Cluster. But the Speed dosen`t work.

I have change the ABS Unit from Europe Spec (Bosch) to a US Spec (Sumitomo) without DSC.

The ABS light works correctly, i think. If i disconnected one Sensor the light goes on.

if all sensor connected, the light goes off.

Is something in my Canbus Stream wrong?

Your user stream 2 is sending out "Driven wheel speed", but you have no driven wheel speed source assigned in your chassis and body settings.  Set this to average front speed or similar.

Thank you Adam.

I try it, but it dosen't work. Should i try without Signal from the ECU?
I'm not sure, but the ABS Unit read all 4 Wheelspeed sensors, and send this Information to the CAN-Bus.

So the Gauge Cluster can read this Information directly from the ABS Unit?

 

 

Thank you

[Adamw]

The cluster gets its speed from the ecu, not the abs.  Is driven wheel speed reading correctly in the ecu software now?  

Can you attach your most recent tune.

Hello Adam

Yes i see 50-60Hz on the rear Wheel Speed in the ECU. But the Cluster dosen't work.

(at the moment i only can test on the Car lift, so the front wheels aren't turn. So i set the driven wheel speed to "average rear speed"

Speed should be in byte 4 & 5, you have it in byte 2&3.  Change the start position to 32.

Thank you, now it works
