Steering Lock: cut one wire. /switch optional

LMBmikeZ · 06-04-2012, 07:32 PM

Forgot to post last week I have been super busy past couple weeks.

Any way, I got my harness (one of the original beta harnesses) last week and installed it that day. I notice no delay like others have stated in other "for real" threads. Thanks again for the harness Brian!

I was hold off to comment but figured WTF I will now. IMO the reason people are experiencing a delay when starting the car with a pulled fuse is because the computer has to go through extra steps to ensure the car is safe to start. Those wires I commented on in an earlier post have a purpose. Without these the computer will then have to run more tests (this all happens within micro seconds) to ensure the car is in a safe state with no faults before proceeding. The CPU runs in a car runs the same as a CPU for a PLC program (I use at work all the time, I am an electrician) CPU's run off of ladder logic and buy disconnecting this wires and creating more work for the cpu only means it has to run through more rungs in the ladder system. So in turn this means it will feel like the car is taking longer before it turns over and starts.

The beauty of the plug and play harness is it can easy be restored to factory state either by re-connecting the brown wire (as you did) or completely remove the harness. There are so many other variables here that could be in play (fuel, temp, driving conditions, the throttle pedal is close to where you are installing etc) and when measuring something subjective this is also even harder. Temporarily installing a switch would allow you to compare with and without brown wire connected much more easily and also remove some of those other variables. It will still be a subjective measurement but at least the n will be higher. With a switch you could even do a blind trial with a passenger controlling the state of the switch and scientifically put any psychosomatic theories to bed

Thanks for the suggestion, bdl99. However, the thought that my unconscious projections were coloring my experience was put to rest shortly after I reconnected the brown wires and drove off. The perceived loss of throttle response was gone and so was the more pronounced lazy shifting that had developed--I have an automatic. I know what I've described sounds weird, but it is my confirmed experience. But I do intend to try some things before abandoning this steering lock solution.

It would be quick and easy to wire up a temporary switch with long leads to the passenger seat if you really want to test it.

How would wiring a switch in make any difference, I am not following? It's convenient but connecting and disconnecting the brown wires achieves the same end.

Simply for the purpose of a scientific test should you want to carry one out. The switch can just be wired as a temporary setup and held by the passenger. That way the switch state can be changed under various conditions without the knowledge of the driver to rule out any perceived effect.

Thanks, that is why I suggested a few more tests. I wasn't saying it didn't happen but rather something else may have been in play.

Simple install and I can rest easy that the Z will not leave me stranded

If anyone is in the West MI area and needs this installed, PM me.
I will install this for no charge. Well, maybe a beer.

ETA on the next batch of cables?

To those who responded, thanks. I'll comment at a later time if/when I get this issue cleared up.

I have two spares in stock and have just updated website to reflect that.

After they have gone the next batch is due to be complete in 2 weeks.

I see your point. However, from my point of view a scientific test is that it can be subjective as well as objective. My method just happened to be subjective in this case.
I don't tend to dismiss a "perceived effect" if it makes a continued impression. I very often notice things that other people just don't perceive. For example, the satellite radio reduces the throttle response when it's on; when FM or AM or CD is on, I notice no appreciable difference.

Nothing wrong with being subjective as long as it is objectively subjective, a double blind test would be just that. You give subjective output based on unknown input parameters. The results are then objectively analyzed.

Beyond that if an issue continues then you may have a grounding issue or potentially an IPDM issue. You can also evaluate the data on the ODBII port for throttle pedal position as well as throttle output to rule out any issue with the pedal output voltages.
