The best in my specific case should be having minimum speed into the ECU as it is for the rpm, I will put 3000 rpm on the ECU. The minium speed on the TC is not relevant since the car is not moving and see confusing speed on every wheels, the TC is not able to see that i am stopped. But as soon as t...

I started to have a small issue last 2 weeks ago. When the car is not moving, the TC see weird speed, with big fluctutation, like 40 to 200 km/h with all wheels reading different speed. As soon as the car is moving, the speed is good, as soon as 2 km/h without problem. The effect is a stopped, I am ...

I am taking few minutes to give a feed back. Everything works fine, the TC look like working pretty well on street. I did not tried it at the race track yet, but I will soon. The only minor point is in order to communicate with the ABS, I need to remove the power from the TC and input. Not a major i...

Please see my TC wiring diagram, and please confirm that it is switched the right way, and well done.

Thanks

Change on my order from Bosch, I will receive the ABS M5 updated version which have output directly from the controller. Now, it is not clear at all for me. I will copy the text from the manual. Option 2: Wheel Speed TTL ABS M5 delivers wheel speed Hall signals for FL, FR, RL and RR wheels as output...

Ok cool.

The waveform is a square pulse, and I suppose is 50/50. The voltage is just shown Ux V, but based on my experience on Bosch industrial stuff, it is probably the actual voltage at battery when the engine is running.

Based on what I can see on the manual, the output look like a straight +12 V, one wire per wheel with a one ground for all. I suppose it needs to be connected as active sensor with no ABS controller, with a 270 ohms. The switch turned "on" on the TC box.

This is my bet.

Thanks

It sound like I will need to do some trials... Bosch are answering not cut the hardness, and use the output from the optional speed sensor box. Typically, those outputs are going directly to the ECU like used on Motec as well as on the original ECU of the Lotus Elise/Exige. And they said you need to...

On the help menu it is indicated to splice the wire between the ABS and the speed sensor. My question is to confirm how to connect the the TC to the ABS output, I suppose it is just straight forward, please confirm. Please see attachment, with the outpiut interface. The link to the original document...

I have a question about the wiring for the TC when used with an ABS Bosch M4. First, recap about the ABS Bosch M4: it is the ABS made for racing purpose from Bosch, programmable for the car, with a yaw sensor, and pressure sensor. The ABS is using active sensor. Now, my question is how to connect th...
