Default Python Alarm system help

So, I have a 2005 wrx with an 05 sti drivetrain and a Vipek standalone ecu.

On the stock ecu, the car runs just fine, no issues.

On the standalone ecu, the car has an unknown rev limiter at 7k, the buttons on the 2-way are switching commands, and the alarm is going off after you start driving.

My question is, is python security systems compatible with a standalone ecu? Are they hard to disconnect/rewire?

Any help will be greatly appreciated! This is the only thing standing between my car running and being back in my possession or remaining at the current shop it resides.

Mods:
2.61 liter- bored, stroked, sleeved
272 cams
ported 2.0 liter wrx heads
rotated 3076r perrin kit (soon to go bigger)
Perrin fuel rails
Aeromotive fpr
walbro 400
Vipek standalone ecu
full 05 sti drivetrain
Python security/car starter
many more but these would effect the car running.

Once again thank you for viewing this and any feedback is more than appreciated!

-Ben

The alarm system is in no way related to the ECU.

Put the factory ECU in and take the car somewhere to troubleshoot the alarm.

That's good to know! What could be failing that's making the car constantly try to start or have the alarm randomly go on? Could it be the remote is bad?

Can we get a little more background info? Has the car ever been running correctly with both the alarm and standalone ECU in the car? Which was put in first? When did the issue start happening?

Did you install the alarm yourself? What alarm related wires did you connect at the ECU? Tach is common there, but there could also be connections for the Neutral Sensing Wire and maybe others.

When your alarm goes off, if its a two way remote system, they tell you what zone is going off. Whether it be hood pin, door trigger, shock sensor, etc.
Find out what zone is going off then we can be of more help (:

Alright so here is the dealio with this car. I bought the car with the alarm system in it. Don't know if the previous owner installed it or if a shop installed it. Car was a basic stage 2 2.0l wrx, nothing special. Most of the wiring he presented us with looked like it was done by a 10 year old. I recently just "finished" building the car. Now it runs on a stand alone. It was fine until the shop I brought it to found out why my ecu had a 7k limiter on it when all the parameters were set past that. So, a day or 2 after they solved that (xmas eve night) the car randomly tried to start itself with no one near the remote. Since then while the tuner was driving it, the alarm randomly started going off and the doors locked. On one occasion when I was driving home, I had to make a quick stop. I shut the car down and the starter just started turning over trying to start the car. I didnt lock or arm the vehicle and the driver side door was still cracked open. Even with the car idling the starter was still trying to turn the motor over. Once I put it in first and started driving the started stopped. As soon as I got the car home it hasnt done it since. The car has a competition twin disk clutch and they recommend disconnecting the clutch pedal switch so your not pressing on a dry thrust bearing. But its confusing because at a high rpm around 7k-7500 the car will completely cut under heavy acceleration. The tuner data logged it and the fuel delivery is perfect except that one instance where it cuts the fuel goes very rich leading us to believe its an electric cut. Could that happen with a bad alarm system w/ remote car starter?

Not sure if it could be the wiring the previous owner did/had done. If its the system itself. If it can be run with a stand alone. If the transponder is on its way out. I honestly have no clue.

Also there seems to be a constant electrical draw. Brand new battery will last 3 days if the car doesn't get ran or charged.

Yank it out. Then rewire it if you still want it. If its giving you that much headache and you've built everything else, take half hour and yank the bastard out. (:

Well found a local dealer who reprogrammed and fixed some wiring. Still have the ignition cut so going to start troubleshooting.

May have found the cause of the cut too! Used the remote start to warm the car up yesterday leaving a friends house and what do you know. The car was constantly cutting out in all gears at any rpm. Gotta check all the wiring in the dash to make sure its not a loose connection or something.

Could be a cold solder joint on the tach signal.

check all your grounds and verify all connections. go to www.directed.com and find a copy of the install manual.. you will need the exact model # of the remote start in your ride to get the correct manual.

When I troubleshoot someone else's spaghetti-mess.. I take a sheet of paper or a spread sheet on my laptop and list every wire color. then as I find where they are going I note them on the spreadsheet. then I go back to Directed's wiring look-up and verify.

the random lock/unlock and oddities scream bad ground or poor main harness connector.

Thanks for the info rob! Ill definitely take the spreadsheet idea! I had a local shop clean up the wiring but I am not sure if the did or not. Ill be tearing it apart and checking the connections and cross reference the wires. I hope they still have the manual for my model.

So come to find out the alarm system is a dealer install only. They won't release the wiring schematic... -_-

But we did find the main harness and pulled all the fuses. Guess what! No more ignition cut. So good news is we solved the cut.

We found the issue. When the cars battery dies constantly, the car and remotes communication becomes disrupted causing the wrong signals to be sent and read. I just had to reprogram my remote and it was fine
