ignition upgrade

[nismofan14]

Alright here is my situation, I bought a new msd sci ignition off a friend and called msd for a diagram and they sent me one. I later found out after i tried to install it that the sci cannot be used with our cars...unless i was told wrong? I just wanted to know if anyone has an msd ignition installed in a 240sx with an internal coil. I think I am going to use the 6al btm but i would like to have some input on it or any other ignitions out there.

We have an internal coil that gets a signal from the ECU and passes it to an infrared eye. You need to find the signal wire coming from the ECU and tap it for the 6 AL.

Ha, Thought the diagram they sent me was no good. The one they sent me has the 2 wires that are on the coil harness being the only ones used. Here is the link to the diagrammsd diagram So if you say that I have to tap into that signal wire, I would do that on the harness for the camshaft position sensor since the 2 wires they told me to use do not emit a signal? I am assuming that you have done this install so maybe you know which wire it would be? Thank you for your help.

Don’t you need an adapter for OBDII?

I swear some one with an OBDII altima had to get a special adapter from MSD

Yes its a tach adapter but it is not always needed but i have it anyways. If you dont have it the tach reads off but the ignition still works. But some 240's don't have problems.

Oh yeah that’s right…nothing to do with ignition

If I where you I would get with MSD by phone and see what they say about a 240 and OBD2.

ok but the tech support over the phone isnt the greatest. Does anyone on this board have a 240 with obdII that has done an msd install on it? If you look in the sept. issue of sport compact car on page 154 there is the 4 steps to turbocharged bliss. It has a picture of a turbo KA motor with the 6al BTM in the engine bay. Apparently this can be done but it seems like the only way I can find out is to contact someone with the install.....I just need to make sure before I fry ignition components.
