Split Second Engine Controler....anyone have experience??

[Rice Eater]

I was just reading up on Split Second's website about the products they offer. Anyone running this? Seems like a reasonable way to adjust air-fuel and timing to take advantage of air intake, headers, exhaust. My main reason for looking into this is to adjust the tune for when I am running Nitrous at the track. I was considering a VEC2 but I've heard lots of headaches with that. I'd appreciate your input/ suggestions.:rock: :burnout:

Thats the controller used in the Paxton

I'd put my Split-Second controller up against any Vec II. You put that controller together with a good broad-band Air/Fuel gauge....and for a lot less money than the Vec II and BINGO!

Ive got slight experience with it, whats your question?? With these trucks you can run both tables, fuel and timing, but your going to need to do a COMPLETE full tune. With the way the box is from Paxton, your only using the timing side and not the fuel.

With tuning the truck yourself, there's many thing you would need....

A scantool
Wideband
Dyno (or a lot of land )
Laptop
Software
And a few other things here and there

Quick....how hard would it be to dial in my truck for nitrous at the track coming off the street tune?

 

[Rice Eater]

I'd assume you'd tune it on the open road while spraying the nitrous watching the air to fuel and retarding the timing a bit...note the settings on the dials and just turn it to those settings when ready to spray? I have no clue on this stuff!

Once again, I'm not a tuner by any means, but if it was my truck and I wanted to be safe...You can run nitrous on a street tune just fine, you just need to watch you air / fuel and make sure your not detonating. If you have a data logger, I would run it with the Nitrous, get your air/fuel perfect (can adjust that with the nitrous jets), then dial in your timing. Go a few degrees at a time.

once you get your 'map' dialed in, save it then keep it stored on your laptop. When you go to the track, you can upload it to the split second box, as a nitrous map

To go along with what you said I think I would pull a little bit of timing first on the upper end just to be safe. Then start addeing it back after the A/F are right. My $.02

thanks guys....i am torn between this or a VEC....pole?

Stingray which ddo you think is better, the vec or spliy?

Chris Jensen :dontknow:

He's the tuner for Dan Cragin @ dcperformance inc.
He's tuned most of the west coast Trucks that are going FAST and NOT BLOWING-UP! lol

The benefits of the VEC are that IT will control your nitrous....there is misc complaints abouts the VEC not working....

 

[Scrambler1]

I just finished pulling that sorry VEC off mine and putting on a split second. Most people I have talked to have had problems with the VEC. I'm not running nitrous so the split second will do more than everything that I need it to do. According to BOOMER, with the blower flash I have from him, the tuning that I need to do is minimal.

 

[Rice Eater]

scramblere....do you already have it installed?

 

[Scrambler1]

Yeah its already installed. Going to dyno ASAP to check things out and tune, but for now driveablity is better than it was with the VEC, idles much smoother.

Well I have no experience with the Splity, so I can't say what is better. But I have never had any problems with the VECII. I think a lot of the problems are caused by the person installing it :dontknow: . I wouldn't hesitate to buy another one. And like Blakewilder said, it can trigger your nitrous and it also has a PWM (pulse width modulated) output. Swapping out tunes take only a few seconds too.
