SM2 & 500R on SR20DET (GTiR) Problem

[Seaman_R]

Hi.
I own Nissan Sunny GTi-R, i have installed all the hardware for the SM2(1.93) & 500R, the problem is that i cannot run the two double ended coils set up that i want. The one of the two ignition outputs of the SM2 specifically ignition 2 does not have any voltage.
Sorry for my poor English.

I can not really understand your problem.
Have you tested the outputs with a scope? If so you need a pull-up 470K Resistor to 12 Volt for that. What is your problem?

Are you missing an output? We need to see your cal file, what cyl pulse/sync % value do you have?
The sync sensor is needed for both outputs to work.

[Seaman_R]

Yes, i have test outputs and work only ign 1 O/P. I don't know the cyl pulse/sync value right now, i will have it tomorrow. I try to take a signal from 2 different spots, from crank trigger(60-2) and from distributor. What do you mine sync sensor and where i need to put 470k resistor?

[MRMRacing]

The resistor is normally needed if you measure with a scope. Post your cal file here so we can check it. You are using 60-2 trigger with the SM2. Have you (or your dealer) done the highspeed mod to the SM2?

[MRMRacing]

The SM2 chip 1.93 do not support 60-2!

[Seaman_R]

Ok. but when i try with distributor i have the same result. Highspeed, it means????
I buy the staff from ebay and i don't have communication with any dealer!!!

[MRMRacing]

Forget the highspeed, 1.93 does not work with 60-2 trigger. This is only done one SM2 that can handle 60-2 triggering. you need 2 teeth at crank where one is located 60 degrees BTDC. and then a sync pulse occuring around TDC.

[Seaman_R]

I understand!! With this setup will work the second ign O/P?

[Seaman_R]

And my cal...

[MRMRacing]

I have checked you cal file, it is set up for throttle/map but the fuel table is not set correctly. Autronic is a very good system but it is never better than the installation or tuning.
You may need some help getting it working fine, where are you located and can you get some experienced help with it?

[Seaman_R]

What you prefer? More rich or poor?
It's better to take a trigger disk for distributor or i have to make a trigger disk with 2 teeth's?
If i use distributor, can i work with 2 double ended coils?
I living to Greece / Athens.

Autronic have a "replacement trigger disc" for sr20det stock cam/sync sensor. It works flawless, and then you can choose any ignition setup you want, sm2 cannot control dwell without modification though.

[Seaman_R]

I have see this trigger to official site. Has someone this trigger for selling?

[MRMRacing]

You should contact Greg that is the Greek dealer, he can help you but will probably charge you for this since you have bypassed the dealer when buying the unit. He has build knowledge and good reputation of Autronic in Greece. In this forum we will support and help customers ECU that has bought from the dealers or as secondhand in your country (but still was sold bu Greg).

If you bought the unit on e-bay for doing it cheaper and bypass Greg you will not get more support here only from Greg if he approve that and charge you for support.

This is to help us dealers spending time and money to get the knowledge to support you.
