SAFC with 2-step problem

sen2two · 11-04-2010, 02:14 PM

I have the SAFC NEO in my s5 TII right now. And i recently put in a MSD 2-step. But for the 2-step to work correctly, I had to wire in 2 solenoids to cut out the trailing coils when activated. So when I activate the 2-step I lose my stock RPM gauge, and the RPM gauge on the NEO because the trailing coils shut off. And that's where they get the signal from.

Will this effect the tuning on the NEO? It does not display the RPM in digital or analog at all. So will it still read RPM and make tuning adjustments when it gets to those RPM?

Can I wire the RPM signal wire from the SAFC to another area, like the tach output on the 6al?

But If i turn the car off, and then restart it, the stock tach and the NEO tach both work again...

weird?

Yes, you can do this.
Make sure the RPM is set correctly to "4-cylinder" or 1 RPM per motor revolution.

I'll try wiring the NEO to the 6al today and hope that fixes the problem. Now what about the stock tach? Is there a way to get that to read from the 6al? I don't really need it, but why not have it working if it's a simple hook up...
