It's a long time since I have participated in the forum, much due to electro engineer/audio technology studies. However, I have now decided to try to wire up my Megasquirt II Extra (PCB v3.57, bought from DIY Autotune) on my 97 tiburon.







In this context, I have some questions.



First of all, I live in Norway, so I have the stock European Tiburon ECU. I think this is somewhat different from the one used in Tiburons in the US. The european version use MAP sensor, but besides this I think the engine and sensors should be the same. My Tiburon got a 2.0l beta engine.



I got several questions, but I start with some regarding ignition settings:



- I got both a crankshaft and camshaft sensor. Is the crankshaft trigger wheel a 60-2 missing tooth wheel?

- Should I use dual wheel settings (both crankshaft and camshaft sensor input), or just single missing tooth wheel settings?

- Is the crankshaft sensor (and camshaft sensor) a hall effect sensor, or a VR sensor?



Regards from Norway.

someone on here did make a post about all the settings to get the car started on a standlone megasquirt in particular. i've been looking but can't seem to find it.

was it me steve ? i did make one. lol

I got both a crankshaft and camshaft sensor. Is the crankshaft trigger wheel a 60-2 missing tooth wheel? 60-2 with First degree of 114

- Should I use dual wheel settings (both crankshaft and camshaft sensor input), or just single missing tooth wheel settings? I only used Crank sensor.

- Is the crankshaft sensor (and camshaft sensor) a hall effect sensor, or a VR sensor? Crank is a VR. Not sure of Camshaft. but maybe the same You ignore the Loop effect ground. Do NOT connect the looped ground to the looped ground on mega squirt crank cable.





Change ign timing too fixed timing. Put 7 Degrees or use a timing light if u have one.. Then change it to use Table.



You need to order urself a 40watt Resister for the Bosch Idle control Valve.



Idle control valve.

Sensor facing you, Tab at top.



3-2-1



3 Close (resister forces closed all the time)

2 MFI (12Volts (run it to your ign stuff like injectors ect)

1 Open (megasquirt IDLE control wire (forces open when needed)





Crank sensor

Sensor facing you, Tab at top.



3-2-1



3 (Megasquirt- White

2 (Megasquirt- Black

1 (Ignore)



(if mega squirt don't show steady RPM swap them around u can't do any damage.)



Cam sensor

Sensor facing you, Tab at top.



3-2-1



3 (Mfi/ Power)

2 Signal

1 Ground ( Sensor Ground to mega squirt not body)

Thanks for the replies



Antonyr123, I see you're from England. Is this the same ECU that your car have?



ECU01

ECU02



Would there be any benefits of also using the camshaft sensor?



Is it the 40W resistors shown here you are taking about?







If I have understood things right, the bosch sensor can be considered a solenoid valve. I got a V3.57 board, and it seems like this means that no PCB modifications would be required to control the bosch valve with the FIdle output pin. Can you confirm this?

Another question after some googling..



It seems that some people have problems with the tiburon coil, since it has very low resistance, and this causing blown transistors.

Is this a problem, and if so, how can it be solved?
