i cut the jumper wire in my compustar 2w900fm-as to put it into automatic mode.. but the car still needs to be set into reservation mode for some reason?

if i let it go to reservation mode the car will then remote start but if i dont, i get the 7 blink error (not in reserv mode).

shouldnt i be able to auto start my car at any time if its in automatic mode? did i miss a wire that i need? does the tranny wire NEED to be connected for it to see its in auto mode? i thought cutting the jumper was enough.

did you hook up the e-brake wire from the brain, cause that will cause it not to go into reservation mode

yes the ebrake is connected.. the thing WILL go into reservation mode.. but i set it to auto-mode by cutting the jumper to specifically not have to go into reservation mode. iv eheard that having it in automode will let me open the door to get something out of the car, and then still be able to remotestart the car at a later time.

its installed in a manual tranny car and 100% i leave it in neutral... and i will wire a relay from the neutral switch to the starter anyways... im tryin to avoid the hassle of reservation mode altogether but for some reason it wotn work without it

i have the compustar in a manual 05 mustang and I don't know about you but I find the setting of the reservation mode to be very easy, it doesn't take anytime at all to do

just out of curiousity why wouldn't you want to have it go into reservation mode, you will have the extra security of not letting it start in gear

you need to remove the parkbrake wire or turn on turbo timer mode.

with the jumper cut, you shouldn't have the parkbrake wire hooked up and if it's just a starter, not an alarm/starter, you should also not have the door input or trunk input hooked up.

You may need to remove power from the unit after cutting the jumper for it to recognize the change.

Shaughn nailed it. Disconnect the park brake wire as well as any other input triggers (save for the hoodpin) if it is a RS only.

ok thanks i'll get rid of the e-brake wire and try it out.

05gt: i know its easy to set the reservation mode, i used the system like that for a while.. however pretty often i have to go grab something from my car, which cancels reservation mode. if this happens to be at 11PM id have to start the car and wait for it to warm up then set reservation mode and turn the car off... all so i could start the car in the morning. very annoying. my solution to the safety issue is to set it to automode and then set a relay inline from the starter wire so that it only passes the signal if the car is in neutral.

How is it going to know if it is in neutral? What kind of car is this in?

its a mazda rx8 and it has a neutral wire coming from the transmission...

so, bobk, as i stated before i am bypassing the alarms safety but ADDING my own safety which i feel will be more effective since it would let me start the car without reservation mode and allow me to open/close doors... yet still provide me with the neutral safety that reservation mode is supposed to. tell me what the problem is?

extreme/jworm/forbidden: thanks for the help so far... but...i cut the parking brake wire and i unplugged the unit for 30 minutes... tried it out.. still get the 7 flashes aka reservation mode not set. i will also use this as my alarm so i still want the door triggers attached.

irfan, you have the location and color of that wire? I had a customer ask me about setting an RX8 up that way earlier this year but I wasn't able to find the info. I have the info for Subaru's and have done quite a few that way.

Recently, Compustar has gotten rid of the loop inside the brain that determines auto/manual mode. They are now programmed from the factory for a particular mode.

I only recently became a Compustar dealer. In my first shipment of units (about 10) only 2 of the units had the loop. I tried using one of them, but kept getting 8 flashes....which isn't listed in the manual. I ended up swapping it out for a unit without the loop and it started working. Maybe there was a time where there was a loop, but the mode is still determined by how it was programmed at the factory. Did you get the unit in the last few months? I think that is when the change was made.

ya i got it from ebay. damn taht sucks if that is the case... maybe i can still exchange it.

the neutral wire comes off the transmission underneath the car.. its gray.. there are two gray wires there i think i cant remember which one it is tho.. test them with a DMM.

You don't have to warm the car up to reset the reservation mode. Just start it up, turn it off, and get out. Takes less than a minute...

I believe the RX8 has a known flooding issue with the engine if it is started and then immediately shut off. I've never owned one or driven one, but it is something I have heard before.

yes the 3000m is the correct unit for an manual car nad this is what i have.. BUT i want the auto version apparantly.

yes the rx8 has a flooding issue and thats the reason i cant just turn the car off immediately. if i could then i would take that route but i dont want to risk flooding the car by turning it off before it warms up.

JWorm.. since you are a compustar dealer do you have an open box 3000a unit i could exchange this with you for?
