WOT box w/ 2-step test vid post#161 - SRT Forums

Brockf98 · 01-26-2008, 01:49 PM

So after reading about your wot box and how it works I thought, if this thing cuts spark for shifting, why can't it be set up to cut spark for launching? Could this be programed into the box or could we use something like a msd rpm switch to tell the box when to cut the spark? just wondering what could be done before I buy one of these. thanks

The WOT Box currently doesn't have that feature. It doesn't have any RPM input, so we would have to find some way of getting one. We'll think about adding it if there is enough demand.

yeah didnt think of that.. get rpm signal to tell it what RPM to cut at.. and wire into clutch switch to do only when clutch pressed..
but probably do go off everytime u shift.. LoL damn it..
im sure u guys can do it..

2 step + WOT Box would be a great combination at the track. I love using the TCS 2 Step and WOT box at the track. If you are running slicks you could probably do without the TCS portion at the track. It would still give you a significant advantage.

Hehe. Yeah, we can do it. We have RPM, MPH, MAP and Gear figured out from one wire in the Toybox.... So we can do it here....

But, the problem is that we can't retard timing effectively. We can only cut the ignition. I don't think that would make for a good 2-step. It would probably be pretty nasty sounding... But maybe not, I don't know....

I have a pretty strong megasquirt background, and from what I am thinking, do you really need the RPM input as well? If you were to cut spark, just from clutch in and WOT signals, it would drop down the rpm, as well as spool the turbo due to the combustion happening in the manifold instead of the cylinders.

Couldn't this be used as it currently sits as a form of launch control?

mmm...2-step

You have to know what RPM the car is at to tell when to cut spark and when to bring it back, if you're going to try and hold a preset RPM for the launch.... But, either way, we can get it, so it's not a big deal.

The question is, is there enough market to do it... Will people buy it?

well, let me ask you this: could it be grandfathered into existing WOT boxes?

Sure, if it's software only. I probably won't do it if it requires a hardware change, since we don't have the time or money right now to come out with new hardware.

But, I think we can do it with software. I just have to figure out how to do it and find time to write the code.

So, can anyone point me to a good explanation of what a 2-step is and how it works? I think I have some vague ideas, but I'd like to see some detailed information....
