Go for it!

 

definitely go for it, when I have enough fundage for a 2nd car its the way Im gonna go. by then the car will be 20 years old and have zero resale so I can do what ever I please with it:lol: same goes for the bosch LH system too

 

Go for it...

 

Hmm, looking more into this, would the Megasquirt replace the APC? Or would it supplement it?

 

there is plenty of potential for making plenty of power using MS on your SPG. Just look at DeLorean's non-runng SPG...non-running because he can't keep the transmission togeather with the power that he is making. Even with the stock T3 turbo you can make more than enough power.

I say do it if you have the money. It will be far easier to fit MS to your car as-is than it will be to fit to any of my current vehicles (which is why I am left at "toying with the idea").

So...DO IT!

 

And the APC system is seperate and can be tweeked to very high PSI - so yes, you would retain the APC system along with MS.

 

the apc system is garbage. the thing about MS is you can set your fuel to sense your boost pressure so a boost controller works way better. APC will still work but its a pussy ass system in the first place. you can make MS do the stuff APC does but i think a manual approach is best. with a MBC+A you will get full boost at less than 3 grand that can hold to the redline (within reason because your still on a stock turbo) and MS can fuel and ignite it perfectly.

 

well, you sure act like you know everything :roll:

the APC is a fine system, its a pain to tweak though, what i plan on doing is keeping it for knock detection purposes. to put it simply, you can plug pin 19 of the APC into the MS box, and it can tell when there is knock, and Ms will then back the boost off, and the timing if needed, until the knock stops, much like Trionic does. as of now, MS isnt able to reliably detect knock on its own, so you would loose a large safety margin by totally trashing the APC.

I would go for it!! I chose Autronic SMC for my engine management system & it transforms the way the car/motor feels. Off boost response is like a new saab due to how timing & all that stuff can be adjusted.

This is what I did

Autronic SMC
MSD DIS-2
Tial ext wg set to 21.3 PSI
Turbosmart megasonic BOV

Not sure why you would want a MBC?

I trashed the APC system, not needed

 

I beleive a properly tuned ECU doesn't need knock detection

 

paul, i bought a knocksense.

I dont want a safety margin because i know what kind of gas to put in my car. also, knocking doesnt destroy an engine immediately. If you have MS, you don't want APC, imo.

 

yeah knocksense is nice, except theres allready a perfectly good knock detection routine in the APC, i agree that its a pain to tune, thats why im gonna let the MS do that, id rather not buy extra stuff that i dont need. and yeah yeah, no need for knock detection, unless you drive your car on the street and end up with a crap tank of gas, or wanna just throw some 87 in there for a short trip, can do that just fine if you have knock detection, cant if you just have a "properly tuned car"

there is no way I would ever think of putting lower octane gas in my car, that would just be stupid!! I am just speaking for myself, other people might be fine but definantly not me!

I would think as long as I stay out of full boost lower octane could be run but for the few pennies a gallon I will not try it

If you want to run cheap gas all the time tune the car for the cheap stuff

 

well the APC along with my megasquirt works wonderfuly... the MS's boost control is neat and has more features... I would not mind trying it, but the saabs APC system works just fine too, especially when moded.

I can't wait to get a working trans in my 900. driving this 9-5 saab gets old fast...

 

and i will admit, most of my experience with apc was on the 84, so its the old style apc.
yeah, i only put good gas in it.. knocking is ok, but low octane knock is alot of knock. lol. it makes me nervous.
