sds engine mangement

[boost_boy]

Ok! It really does look simple, guess that's why it has its name Simple Digital System(SDS).

Two questions tho, one in particluar for Dee - is that the same unit that you used(or similar)?

Second, which one would be best to select in particular - the D, E, or F?

Yes, I use the F system and it's also what I install in my customers cars as well.

Oh Ryan, who's bashing your AFMs? I personally would not let the stock ecu control my timing when I can do it all at my finger tips with the standalone. When I had JWT do both my g/f's ecu and my own to the tune of well over $1000, there was always something missing. And the fact that i had to send the ecu back a couple of times, burned me out. Oh yeah, did I mention the loss of engines. I don't trust no one's tuning when it comes to chipped performance. Experience is the best teacher for me, I was the guinea pig for the U.S. and Canada based pulsar CA18DE ECU remapped for the CA18DET gang. The AFMs I had were big and at least they made the car run, but had too many issues for me. But hey, I know some people have had success with them, so I encourage you and anyone else to go for it. If you're not chasing huge power, then these shouldn't pose that much of a problem.

Ok, this is off topic, but I'm tired of the MAFS bashing. The only possible downside to a MAFS setup is the potential reduction in flow. That can simply be alleviated by upgrading to a larger, higher flowing MAFS. When it comes right down to it, the information that you need to know so that you can inject the correct amount of fuel is the quantity (aka MASS) of air entering the motor. When using a MAP system, you are taking the temperature and pressure of the air entering the manifold, using a table of calcuations, and coming up with the amount of air that way. From a programming standpoint, that is a lot simpler to do, and ofcourse, it poses no restriction to the flow of air. The reason that most OEM air metering systems are MAFS, is because it's more accurate. They are less concerned about horsepower and more concerned about accuracy. The more accuratly you can read the amount of air entering the motor, the more reliable the system is. I like MAFS systems and that is part of the reason that I stuck to the PFC. And to be completely honest, with the computing power that is available today, the differences between the two are probabally minimal, and the potental restriction that the MAFS poses to the air flow can be a deturant. But I seriously doubt that a Z32 or Cobra MAFS poses much more restriction than an intercooler does for the horsepower levels that we are working with. Just my $.02 [/soapbox]

Absolutely. If you have a MAF sensor and add an aftermarket intake manifold, it will compensate for the change in VE very well. A MAP will do a worse job, so you'll have to tune it accordingly. But if you tune it, then whatever restriction, if any, the maf posed is still eliminated. Also if you develop a boost leak your car won't drive like crap if you use MAP. And you can vent the BOV and you don't need to worry about incorporating the MAF sensor. I think it simplifies the setup, once the wiring is worked out that is.

Two words: Blow Through

Mine is going to be setup like that, just after the intercooler. I'm still going to run recirc'd, but I think I'll be able to tune more accurately if I can run it that way. We'll see what happens...

[radmar1]

how hard is it to install the sds

[GoofyATX240]

Its pretty straight forward. Real easy.

[radmar1]

what is this that i have been hearing about doing something with the crank

[float_6969]

what is this that i have been hearing about doing something with the crank

Stay away from that stuff. Drugs are bad man...

[radmar1]

well i heard there is some trick to hooking it up

and float 6969, honestly i dont know what your problem is, so why dont you tell me. Im just asking a question, the question was not even to you, but every time i ask something you have some dumb a$$ remark everytime. Every body i have met on this board has been great except for you, honestly either leave me alone or we can deal with this out side of this forum.

Im not trying to strart any problems with anyone but seriously this guy has been a gerk

chill out buddy. ryan's not being a "gerk" he's just trying to make a funny statement (althought I will admit, it was a pretty feeble attempt at humor, even by his standards) . we're a lighthearted bunch in here, deal with it. A change of attitude is definatly needed my friend.

and just to help you out, since you seem to have something up your butt, here's a picture of EXACTLY what you need to modify.



Here's a perfect shot of the hall sensor bracket customized to accomodate Dee's SDS standalone.

Dude, I wasn't trying to be a jerk at all. I just joke around a lot. I really don't have anything against you at all. Just as Sean said, we try to keep things lively around here and I do my best to instigate.

Maybe this will make you smile, it always works for me!

[themadscientist]

Float, you're a jerk.That's why I love ya, do the persian dance for me again!

[float_6969]

How about a line dance...

This guy is hopeless

[radmar1]

well if that is his way of joking, then thats fine but i am not hopleless just because i was asking a question

[float_6969]

Dude, he was talking about me, not you. He was saying that I am hopeless. That's why he quoted me. It's all good man. We're all just here for fun. To quote a line from the masterful Quintin Tarentino (or however the hell you spell it)

"Are you cool?......Yea...I'm cool."

[themadscientist]

The wife say's I am NOT cool but she married ME so her judgement is definately suspect.

[radmar1]

ok cool, everything is cool just forget about it.

So im getting the sds then

[boost_boy]

well if that is his way of joking, then thats fine but i am not hopleless just because i was asking a question

Yeah man, I was referring to Ryan and that's why I quoted him.

I would think the larger MAF problem would be the loss of granularity as the MAF's diameter (and consequently the maximum airflow it can read) increases. 0-5 volts over a 250HP airflow range is pretty good, over a 500+HP airflow range seems like it would lack precision.

Of course if there are MAFs that have larger voltage ranges my point is moot.

The same thing happens with MAPs. A 2bar MAP has a higher resolution than a 3 bar one.

I'm not sure it happens with MAFs though...

does anyone know SDS website??? thanx-g
