Haltech Launch Control
#42
Kevin,
If the you have this activated with the clutch pedal ie: hold 3000 rpm while depressed what happens when you go and change gears after the launch? Wont it limit the rpm back to 3000 rpm when you depress the clutch to change gears or are you saying that before changing into second you will flick the override switch.
Seems a bit like rubbing your head and tummy at the same time
Also I assume this should be a normally open switch not a normally closed as indicated above as the instructions say that "To activate the Aux Limiter, connect the AUX Rev Limiter Input to the ground wire" which would mean if you use a NC switch then it would be grounded and restricting RPM
I have attached below a crude diagram on what I understand. If it is wrong or you have done it differently then please post a simple diagram. Maybe it is too late and i'm missing something.
EDIT: To make sure we are on the same page when you say B12 you are talking about the AMP 2 POS connector and mean Pin 1 (Input) and Pin 2 (GND) or do you mean B12 on the white middle ECU connector which is labeled "Vehicle Speed" according to the diagram I have.

If the B12 is grounded, it will the by-pass the aux. rev.( rev to 7k) or whatever redline is. If the B12 is opened from ground the aux. rev will kick in.
The clutch switch is a normaly CLOSED switch, so unless the pedal is to the floor and switch opened to ground it will not free rev.
I'm not worried about between shifts that the clutch will tap the swtich, it won't make any diffrence.
Does this help?

Kev, Yeah it does.. I will need to confirm something with haltech as the instructions I have been given is that the AUX Rev Limit is controlled by the 2 AMP POS connector hence my confusion when you say B12.
See below.

Im sorry I had a incorect diagram, I changed it, it is now correct.
Hal sent me a pin to put in the Haltech connector B12 location, he said some units had been wired and some had not. I bet yours is pre wired. Can you trace down the wire from the 2 amp pos, and see if it goes to the B12 location on the harness?

Okay tested it this arvo using my 2 POS AMP connector
With the circuit open between pin 1 and pin 2 it will restrict rpm. So to get this to work on the pre-wired harness you will need a normally closed switch as what Kevin used. The instructions to me are a bit misleading. I have included a diagram below to help anyone with there own DIY.

Just to clear up any remaining confusion, there are two harnesses. The old ones did not have the auxiliary rev limiter position populated (such as yours Kevin) and we have those pins for anyone needing them. The new harnesses have a two wire connector containing the wire from B12 and a ground.
When the auxiliary rev limiter is enabled in the software, the trigger wire (B12) needs to rest in the grounded position. To trigger the auxiliary limiter, the connection to ground needs to be broken.

That combined with the fact that individual wheel speeds and calculated wheel slip values are coming through now will lead to the more advanced traction control features in the future.
