hey,

so my car was getting harder and harder to start because of my mongoose mx40 immobiliser, so one morning it stopped working (i only have 1 remote) and so i pulled the battery out, its a23 battery only had 6.5v so i was like well i guess that is the problem, bought a new battery and it would work first time everytime,

then about a week later went to start my car but it wouldnt work, so i fiddled with the battery but still didnt get anything, left it for 2 more days as i was pissed at it and it worked straight away,

so what could be wrong with this? the remote maybe? anyway of getting a new 1? the red light does come on when pressing the button, so i really dno what it could be?

any help would be good,

Cheers

hey found the problem, it was only a flat battery. i had 1 volt left on it lol.

anyway the alarm guy also told me everytime u change the battery u have to arm/disarm the little black box thing (dunno what its called) thats next to the battery with the little key that u got with ur alarm. (kinda looks like a steering wheel lock key but smaller).

otherwise ur car won't start.

hope this helps.

I've just recently encountered a similar problem with the M80 immobiliser.

The range at which I could open my car (Since the remote serves as both arming/disarming the engine aswell as opening/locking the doors) significantly decreased over time, indicating a fade of battery life.

Sure enough, it eventually stopped working however, luckily I was at home and I was able to get my spare remote.

After reading this thread I was intruiged as to what "key" you are speaking about? Is it not simply a change of battery and away you go?

I was simply given two remotes with a safety card and pin incase I ever cannot use the remote.

Unfortunately I cannot send PM's yet (since I roam the forums and never post :)) - Hoping someone can help :)

I guess he's talking of the small key to turn off the siren.

Without that key, you can't easily remove your car's battery. The siren has its own on board power and it will go right off as soon as you remove a battery terminal.

And with the alarm within 1m of your head its frikn loud as fk lmao. Remember having to change the battery in my old car and forgot that key much fun.

With the battery backup sirens, its quite painful doing any battery disconnecting without being able to turn off the siren.

I have a problem with my M80, when I turn the car off it should time out 20 sec before the immobaliser kicks in and the display LED flashes fast, then bam it immobalises it self. But some times after turning the car off the LED doesn't flash or come on at all for around 1min and when I get out the car it won't lock, have to do it with the key. Strange much?

Having the same issue, randomly started. Alarm rings but dies not lock or unlock the doors. Led flashes rapidly when unlocked and then it immobilised and resutns to normal flashing. Any help guys?

Often fast flashing led after disarming is a sign that the alarm had been set off and needs resetting to clear the code, my old alarm the number of flashes told you which sensor was activated. Not sure this will fix the issues or if its relevant to your alarm, but search for how to do this and give it a shot.

Thanks to another member on this site who PM'd me, my thoughts were confirmed. The twin connector bit that connects the door lock rod and the actuator rod had come loose and so the alarm didn't know that the door had locked or not.

What I did was:

Take the door panel off,

Replace the missing screw on the double connector

Enjoy the locking/un-locking door :yes:

You would be better off finding an N15 pulsar door catch assembly and swapping it in. You will not need to adjust that at all.

Been told this a few times. Perhaps when it breaks next time, ill change it out.

      By GTSBoy · Posted

      You've done it wrong. I don't have time right now to type up enough. I'll have to come back to it or maybe someone else will in the meantime. The boost signal has to pass through the MAC valve from boost source (turbo outlet - effectively anywhere between the turbo outlet and the throttle body will do, but closer to the turbo outlet is best) to the wastegate. What you have done is connected it sort of like the stock solenoid. But it doesn't work the same way as the stock solenoid. That Tee piece that you have connected the solenoid to....? The solenoid itself serves that function. You should look up a typical MAC valve connection diagram for a single turbo internal wastegate application. You'll find one easily enough. Every single boost controller manufacturer that uses MAC valves will have one. Bugger it, I'll just grab the HP Academy one. The other thing you have to get right is that the boost source has to be connected to the correct port on the solenoid valve. This is because the solenoid makes the valve switch from connecting 2 of the ports when it is unpowered, to connecting one of those first 2 ports to the third port when it is powered. One inlet, two outlets. You will note from the diagram that the common port is port 3, the port to the wastegate is port 2, and port 1 is the vent (where the boost signal escapes when the solenoid pulses ON). As to the BOV.... the vacuum signal for the BOV simply has to come from the plenum. It must register boost when you're on boost and vacuum when the throttle is closed. That's all. The original location on the plenum is best. Best practice is never to interfere with the vacuum line running to the FPR. Just leave that one alone, as you will avoid causing unintended problems that might occur if you mess something up.

      I was able to complete installation of the G4X ecu. I needed to reroute MAP vacuum signal from stock location to where BOV is connected on the intake plenum. Has anyone needed to do the same? When I connect vac port by the BOV flange to my HKS BOV, it doesnt work and I get flutter. I would to get BOV working, where would it be best to T in? Or would it best for me to move MAP vac line and T into FPR? Secondly, I installed a MAC 3 port boost solenoid and wanted to know if i routed it correctly. I place two lines from stock boost solenoid and placed it on ports 1 and 2, leaving 3 vented. The T for wastegate and boost source on compressor elbow is on port 2, and port 1 is connected to turbo inlet intake pipe. Please see attached pictures. Ill upload ecu config later today. Thanks in advance.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      So I raised the car up a fair bit for shipping - see image - then lowered it again when it arrived. I then rushed to get an alignment in NL before the track and the shop just wasn’t anywhere near as precise as what I got in Japan. The guys that did the alignment this week said there was a fair amount of toe in the rear that could have contributed to the understeer. It was also the case that the rear camber went from about -2 to -3 at the shop in NL. However, since I’ve now got slightly wider tires in the rear - NS2Rs run wider than Accelera 651S - I could only get a minimum of -3 in the rear now due to clearance. Front is now -2.75 (-2.45 in minutes) due to being raised a bit (previously -3 in JP). So it’s likely a combination of the two factors, camber and toe. The issue now is I have more camber in the rear than the front and the next step on the front Cusco arms will put me at -3.5ish front which seems a bit excessive to me. The weird thing is I’ve never had any understeer at the track in Japan but they are very different circuits - Japanese circuits are much slower than the one I’ve been to here.    I’m probably going to have to start another thread for the E90. The plan is sort of to keep it as a daily but progressively mod it into a track car - honestly, you need a cage for the sort of speeds you go here. Just ordered the M3 front arms btw.  Love the car despite it being in pretty shitty condition. Oil analysis came back okay and it seems to have stopped consuming oil since fixing a load of engine bay things. Saw yours is a 335i right? f**king mistake on my part getting the DI N53 over the N52, fuel economy is insanely good though at 14-16 km/L.   Cheers, it’s great to see the benefits and pitfalls of different places. I’m contemplating going back to the U.K. around next year as the cost of living in the Netherlands is just ridiculous. GF is nagging me to settle and buy a house but I don’t know what LSD to buy.
