timbo, Dan...MegaSquirters I need your help

I strongly suggest you run only fuel control.
The stock KS system is already a mapped electronic system with knock 
control. The MS can incorporate knock control, but it's already there with 
the stock KS system and I'm pretty damn sure you will not be able to improve 
upon the stock map without a LOT of dyno time.
If you were going to run forced induction that would be a different thing in 
that the stock KS is not mapped for boost.
But for an NA engine I imagine the stock KS map is about as good as you can 
get.
I'm not knocking your skills or knowledge, but there is no feedback tuning 
tool for ignition like there is for fuel. And before anybody chimes in and 
say advance till it knocks and back off 2° I'll simply say for an NA engine 
best performance is NOT necessarily just shy of knock, especially at part 
throttle!!

Inject Dan attitude. Why would everyone suggest spark control right off the 
bat? I cannot tell you the number of people that do not believe you should 
run 45° advance at 50 kpa and 3500 RPM yet that's what a stock JH of PL 
ignition will produce. Really just use the stock KS unless you're going 
forced induction. Damn few people can improve upon it!!

Yes you can pull a nice square wave signal off of the ICU pin 7.

I haven't done anything with the ISV control so I have no input there.

Ok I'm at step 55 in the assembly process. I've got a working MSI PCB V3.0 
I've got the circuits installed for inputs, but haven't started on outputs 
yet.

Here's my problem... I'd like to eventually run MSnSE and control spark, but 
right now since it's my 1st MS project I want to do stand alone on my 86 
Jetta GLI (yes it has a knock box and locked dizzy so that won't be an issue 
later)

Everyone tells me I should just go MSnSE and control spark right off the 
bat.

I'd like to run just fuel management 1st...So where do I tap tach signal?  I 
think Timbo's drawing was using pin 7 of the ICU?

My next question would be PWM and ISV.  How have you set these 2 up?

Thanks for any help
David
