Ignition type & details for AIC tune???

[pk2]

Hello,

I have a Perfect Power SMT6 AIC I want to use on my Supercharged Boxster. PP has no installation notes specific to this car. I can muddle through it but I need some general infoemation

Ignition: The manual goes into great detail on all sorts ways of determining your ignition type with an oscilloscope. I don’t have easy access to one. So Inially need to know the following

#1 question is, what type of ignition doses this have ignition? choices are:

a) Missing tooth operation
b) Single Ignition advance & retard + frequency fuel
c) Single ignition advance & retard + road speed governor
d) Two ignition advance & retard
e) Single ignition advance & retard + PWM fuel
f) Odd signal retard

#2 How should I determine the dwell ?

#3) Number opf teeth on flywheel and (get this) number of teeth per firing?

Thats all for now,

THanks in advance,

PK

Missing tooth, 60-2.
You can calculate the teeth per firing using the method in the manual.

Hmm, Iwas just told that the missing teeth were just to identify TDC visualy. THe actuall sensor was 15 teeth away...for whatever thats worth.

# of teeth fror firing, I'll have to dig into that then. That manual isn't the best for navigation. Not sure what I'm looking for.

Thanks,

PK

I really don't understand what you are saying, the Bosch system is a 60 tooth missing 2 setup. Pretty standard. If you don't want to believe me that is fine, but I have used an SMT6 on a boxster.

Hey Todd,

It is indeed Its 60 & 2, no belief or faith required.

You put one on a Boxster, I was hoping I’d bump into you, you steered me away from a Split Second and to PP last October when I was putting this (SC) in. Finally took your advice.

The 15 degrees off tdc for the sensor target is a long, long story and irrelevant. Because of that, I’ve just got concerns about the knock circuit. Tell me the SMT6 you set up with both timing and AIC control flew without radically modding the ignition circuit and I’m good.

Can’t find a “teeth per firing” reference my book yet. Based on the crank degrees for valves opening and closing though, I’m getting the #1 combustion chamber closed up for 96 degrees or 16 teeth

So “teeth per firing” is 16…sound right? (or half that…just the down stroke)

Well this is keen, still nothing in the P-manual but at the end of the SMT6 book there’s this definition for ”teeth per firing: amount of trigger signals between firings”. If the sensor = a firing than its 58(?).

I thought there were 3 firings per rev. than ”teeth per firing”=19.3
