Vortech SplitSecond Box doesn't do fuel control.
 

OK, just want to clear something up. Called Vortech tech help line today. I was told that the Split Second box that comes with the Vortech Supercharger has no control over fuel management. The tech guy said it only does timing control. When I mentioned the fact that people here are saying they can control their fuel levels with the box, he asked another tech that is very knowledgeable in the system. The other tech also said it only does timing control.

So that would mean that the only fuel control is a mechanical FMU. So, which is it guys? Does the Vortech tech not know what he's talking about or is the SplitSecond box just a timing controller?

Odd you should bring ths up ...

I talked with SplitSecond today about the unit included with the Vortech system. SS told me that the box included CAN do fuel if you use the R4 software to tune it. Vortech only uses it for timing control though.

Better ?

Much, thank you.

split second box
 

thats funny because i got the software from vortech so i could lean it out. it has two maps. map a is fuel and map b is timing. you can add fuel or take it away. timing can only be taken out. i have played with my settings in both fuel and timing.

not true they use it for fuel to.

350zer, can you please send me enthuzed 91 octane map?...........email it to......... wicked350z@wicked350z.com

Re: split second box
 

Well, I guess the "tech support" guys at Vortech didn't know what they were talking about. Why am I not surprised. Thanks for clearing things up.

How's this for proof:

HMMM ... guess I was mis-lead ...

Don't feel bad, so was I. I'd think Vortech would've at least known what the hell they were talking about.

Vortech also claims that the split-sec box isn't tunable.

My best guess why vortech is saying the things there saying is because most people are dip sh*ts and they don't want dip sh*ts tinkering with the SS box because they will blow there motor up and put a bad mark on VORTECH directly. Think about it, I guarantee thats the reason. VORTECH is doing the right thing, selling a product that from them will not damage your vehicle and saying it isnt tunable and the SS box does not control fuel. The smart ones will find out it is tunable and can control fuel, the dumb ones will just think its untunable and leave as is, and thats a good thing for everybody.

No, I think the techs are just dip sh*ts. :D

I doubt it if you really think about what i just posted, you think they know ur one of the smart ones?

Zimbo, Thanks for posting this.
So do those numbers in the matrix represent your target A/F ratios at those points? And how does the box know what PSI (I'm assuming this is from the supercharger) you are at? It's weird because I thought the R4 software works off of voltage, not PSI.

No, that's not a target A/F. Those points represent an amount of fuel to add at the given PSI/RPM cell. A higher number means more fuel--and you need a dyno or a logging A/F gauge to triangulate. You'll notice that the ECU already adds more fuel at WOT, so the numbers at higher RPMs under boost add less fuel but the A/F still goes down.

The SS box has one of those tiny air hoses like you find on a boost gauge and it's fed off of the output of the Plenum. If you drive around with the laptop connected, the active cell is highlighted as you drive (and you can actually record its movement). Pretty cool.

That is very nice! How do you like it compared to other fuel and timing control systems? I seen things like the techno ecu re-flash, afexi afc and the greddy e-manage. Do you think the splitsecond is the best to get?

I would like to point out the Vortech press release:
http://www.vortechsuperchargers.com/news/2003_350z.html

says:
Fuel management upgrade includes a high-flow fuel pump and fuel management unit for safe, reliable operation
and:
Stand-alone ignition timing control computer for seamless acceleration

My $.02.

You work for Vortech. So, why are you guys saying the SS box only does timing and not fuel when it obviously does?

The "press release" says FMU for fuel control and SS box for timing. Seriously, what's up with that. Sounds like they guys on this forum know more about the system than Vortech does.

LOLZY!!!
