TPP window switch question
http://www.fjoracing.com/products/rp.../downloads.php
and the instructions arent very good/ i dont know what to put in for one of the steps.
it is step 1
(tach setup)
BC is the number of cylinders. this setting is used by the RPMWS to calculate the correct RPM.
00= individual coil per cylinder systems where the tach wire is connected to the coil.
01= coil packs that fire in pairs (waste spark systems) and the tach wire is connected to the coil.
02-12= cylinder combinations from 2 to 12 where the tach wire is connected to the tach from the engine electronic controller or distributor.
we, like some others, put the number of cylinders of the car, which is what we understood from that first instruction. apparently thats not right though.
does anyone have any idea what the right setting would be?
edit: here is the link for the instructions

LS1 cars computers signal looks like a 4 cylinder that is why you put it on 04. If you tie into a coil trigger wire, then it is 00

I used an individual coil to get the signal, but the way you wired it should work as well.
Did you use the tach feature to make sure it read the same as your cars tach? If they match then you know its right.
on a side note, do you have any pics of the nitrous install. I'd like to see how you did it.

Start the car and hold down the button that displays RPM's. Hold the engine at 1,000 RPMS according to your real (in-car) tach, and see what the window switch reads.
If it reads 1,000 rpms, then your good to go.
If it reads 670RPMs then change it to 6 cyl. Or if it reads 1300RPM's then change it to 3 cyl.
BTW, I believe it was a black wire with a brown stripe off the coil harness. I had to unbolt the coils to get access to the wires.
Putting it on "04" doesnt seem to be helping me.
Likewise if you are currently set to 4 cyl and the signal is actally a 3cyl signal, then if you engine is at 1,000 rpms *4/3 =1333RPMs
Its real easy to figure out what the signal is with the tach feature of this window switch.
Sorry if I'm not seeing why you're getting those numbers.
