Looking for an alarm system that I can use to alarm fuel pressure, EGT, oil pressure.

Not interested in guages, Just want a system that buzzes loudly and shines a light when something is wrong.

Ideas???

Paul (mountainrunner on the forum) makes exactly this for a good price, Engine Monitor II

Has a series of digital and analogue inputs, and outputs are lights and buzzer.

You set the warning point for each input. Also has a shift light as a bonus.

Really good system, and about 1/4 the cost of an ecu with dash.

I already have a MOTEC M800 and an AIM dash BUT to the best of my knowledge those three functions are not supported.

Will look at the engine alarm module. Thanks Duncan.

Any idea on price?

so the AIM dash doesn't have external alarm option?? Can't you use a pwm on the motec to turn on a light/buzzer under certain conditions? Just seems like it would be a heap of wiring to have the inputs going to 2 devices. I know I can do this with my IQ3 dash

Its pretty easy to install. I do have a wiring table you follow to do it. Plus I'm a phone call away if you have any problems.

The external alarms are really good when you are on track, I built this thing for myself with keeping my engine safe at track days being the primary focus. Thats also why it has the alarm hold functions, external page select and alarm acknowledge buttons (I put these in the centre console on that little verticle surface where your fingers hand when you put your left arm on the arm rest, that way you don't have to look for anything while driving its at your finger tips).

Cost for the unit is $499

Alarm accessory kit $59 (buzzer, 2 stage shift light, alarm light, ack and page select buttons)

Sensors depends on what extra's you need. I have made the unit to be as flexible as possible. If you have sensors already there you can just sniff off them and put the calibration into the monitor. The inputs have been designed to be fail safe and high impedence so any other system will not notice the connection.

Plus you got to love the mapping of Oil Pressure to RPM, and Fuel Pressure to Boost, so you get the alarm as soon as there is a problem, not once those pressures have totally died.

I have to admit I havent really drilled down into either the Motec or AIM data to see if they are capable of the alarms I need. I intend to run the CAN to give me all the normal engine measurements the ECU needs to function correctly. I spose I should pull my finger out and read the books. :)

    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
    • You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
