Possible to start engine without depressing on clutch??

JB-370z

The saftey wire would need to be grounded to something and then your done.

I am not sure about doing it with a push start vehicle, but if I had my old car in first gear, turn the key, and hit the gas it would start up. Obviously, this is not good for the car but it did work.

It's like that for a reason. Saftey! If you want an autostart they sell legitimate alarm systems that are costly but will give you autostart in a safe manner. Had a Compustar alarm system on my car about 700 bucks with autostart. You had a process before shutting the car off, but it was something you do anyway. Very cool so you didnt start the car in gear. If you opened and closed the door it will disengage the autostart. Again expensive but I enjoyed it.

just did this on my car. Installing relay provisions for my remote start i ordered. I used two relays as there are actually two switches on the clutch pedal.

Relay#1 - to open the circuit for clutch pedal position switch coming out of pin 99 at the BCM (a 12V input is normally found on this pin at rest which must be interupted to allow a start)

Relay#2 - to apply 12v to the clutch interlock switch circuit at pin 114 of the BCM. (this pin has 0Volts at rest and requires 12v to allow a start)

Following that just apply a ground pulse to the start button circuit at pin 89 on the BCM and voila, your car starts with no clutch, no push button.

I will be using a proximity key bypass module that powers up the key fob only for the start of the car then powers it off once started. That way the key fob is dead after the car is started and you cannot walkup to the car and unlock the doors with the door unlock request button.

Nice job.

How much did the proximity key module end up costing you?
Is it a regular fob that you removed the battery from or something else?
Did you do anything for neutral detection?

The bypass module cost $40. Its the type that you remove the battery from the fob and it powers the fob up through its own wiring. I have done anything for the neutral switch yet....still trying to think up something safe/creative.

ChrisSlicks

In the transmission section of the manual it mentions a park/neutral switch connector for the 6MT for vehicles with and without S-mode so that might be something you can tap into. See page TM-44 for the exploded view (item 6).

In the BCM section of the manual it is referred to as the "SFT PN/N SW". It appears to connect to pin 140 and is at 12V (battery voltage) when in neutral and 0V when in gear. See BCS-68.

I read in a paper column that modern cars you dont' have to "warm" them up because they are fuel injected. Not sure what exactly that means but that's what i've read.

The engine doesn't need to be warmed up before normal driving but it sure helps when your trying to get a sheet of ice off the windshield. I have remote start in all my Winter vehicles.

After thinking about bypassing the clutch pedal, I've come to realize that it would be absurd to bypass it. Bypassing the clutch would mean that the driver can start the car by a push of the start/stop button. But, that would mean that it would be impossible to go into ACC mode and ON mode. So, in summary, DO NOT bypass the clutch in your 370z.

To completely bypass it would be not so smart not to mention the fact that all switches are monitored by the BCM and ECM. As soon as the car moves above 40kmh for a certain duration and does not see the switch positions changing(ie shifting gears) the car starts to throw codes. Its all in the service manual.

Yet i think you might have missed the part where i said i was installing a remote start on my 6MT. That being said i am not "bypassing" the clutch switches(you cant without getting codes nonstop) the remote start will send out a signal to a pair of relays to "simulate" the clutch being pressed, and only for the duration of the start cycle. Once the car is up and running the relays go back to normal and all functions as per normal. interfacing with the push button, interlock switch, pedal position switch, as well as neutral switch takes a series of 5 relays. all non functioning when the remote start is not entering the start sequence. You can still use ACC and ON mode in my car. I may post my relay wiring diagram at a later date once i get everything finished up.
