i am finally at it again push start

Nov of 2008 i posted up about push button start. https://www.the12volt.com/installbay/forum_posts.asp?tid=108961&KW=rutcgr18

Well it time strart back working on it again.  I am using the basic stamp as my controler   THere will be rfid for securty.  I have pretty much have all the code written. I have put in place leds.  So my qetion is i have remote car starter in my car.  For the start function can i some how pulse the remote carstart to start the car?

THanks

Mike

?

Lets try that again.  I am converting my car to push button start.  I am using the basic stamp as my control.  The stamp is a micro controler.  I have written all the code.  Example yellow light turns on when the starter would turn on.  Green led shows that the car is running ignitoin.  The leds represent what the parts of the car would be on.  So my quesiton is that i have to find a way to start the car from the stamp.  I was hopeing since i ihave remote start in the car i could some how send a pulse to the remote start brain and start the car. 

Here are steps of the car starting
1. Get in
2. RFID check
3. Push button to start car
4. Car runing
5.Push button again car shuts off.

I think i follow...Some remote starts have a - input to activate remote start sequence...Like the Autopage 602/603...Can be used as an add-on remote start...Chech install manual and see...Will peruse the old post ...Did you use the diagram from the old post...Wiring up one more relay to pulse input of remote start ...off button...?

I have not gotten to the part yet.  I have not built any hardware.  Just got the coding down.  The remote starter i have is Viper 5701 Responder

My ohter quetion is once the car is started how can transfer from the starter to the car. like when you hit the break?

ok, i see what you are doing now. so here's my question, are you planning to somehow use the remote start to just do the start sequence and then somehow have the ignition circuits taken over another way? or, are you planning to just use the remote start to power all the ignition circuits as well as crank the starter and just try to run the vehicle like that?

Just want to use it for start seqence.

Why don't you just code the microcontroller to do everything?  It would be a much cleaner install if the system you are building controls everything.  It won't take much more code to monitor a tach signal and in the end you'll have a much more OEM like system.

That makes sense hmm do you have any experice with basic stamp

I've never touched a basic stamp, but I do have quite a bit of exposure to Atmel AVRs and a minimal amount of PIC knowledge.

My RFID based pushbutton start system in my G35 is completely self contained (two Atmel processors) and operates like OEM (down to the IGN/ACC switching and the "push and release" tach based starting).

you and i will def need to chat.  I have my stamp coded the same way push once with out brake pedal is acc and push a second wiht out brake ign and if you push brake and button should start.  So i think i am going to run the whole thing from the stamp makes more sense.  I was thinking for the ign should i make a latching realy setup.  What are you using?  Also do you have any pics? What did you with your key ignition removal?

Thanks

Mike

Why would you use a latching relay when you have a microcontroller?  When the brake is pushed down and the button is pushed turn on an output and keep it on until the brake and button are pushed again.

I went a step further since my Infiniti doesn't have RAP for the radio and I keep the ACC on until the door is open.

I like the radio feature may have to add that one.  So you keep your pin high which is attached to regular relay which has the wires for the ign correct?

Mike

Well, it's not attached directly to a relay, it goes through a Toshiba Darlington transistor array first, but yes, I'm using standard Bosch style automotive relays.

My hardware is basically a copy of every remote start / alarm system hardware out there - uC -> transistor -> device

I just tried to send you a pm says you can rescieve them
