Does anyone have a wiring diagram to wire the Harlan two step in with the Ramcharger's Timing Tuner?

I can't figure out how to wire in the two step to disable the nitrous, while still being able to have the timing tuner control the delay and RPM limits.

Any help is appreciated.

Thanks,
Kevin

 

I've thought about this many times. If anyone knows how to figure it out, I sure would like to know also.

I don't know if it's possible.


The only thing that I can think of is have the 2 step set at a lower launch rpm than the timing tuner's window switch, but that would mean that you can't use the nitrous delay feature, you would be spraying outta the hole.

 

I got it figured. Let me think it over to make sure I'm correct and then draw it up in Autocad. Seems real easy rite now. I'll repost Sun or Mon nite when I get it drawn up.

 

What I was thinking about was to rig up a switch to go between my Wot switch & the TT. You could probably even use a spare wot switch. Mount it up under the dash so that when the clutch is released the clutch pedal lever itself would hit it to close the connection & activate the TT in concert with the WOT switch on your TB. That would keep the TT from kicking in while on the 2 step with the clutch pedal depressed.

The second you release the clutch bam, the TT is activated, your foot should already be on the floor because you were on the 2 step & that would take care of everythign.

I hope you can understand it, it's making full sense in my head, but getting my thoughts down on paper is a different story. I'm sure that it could be done with micro switches & relay's too, but I think what I've come up with is simple & easy.

 

doesn't the TT kick on once the system is armed? if so just hook up the two step to the WOT switch with a relay. maybe harlan will jump in on this.

 

OK, got a question on the TT first. Goin over it on paper and need to know how do u reset the N2O delay on the TT? Turn it off then back on? If it does then every time the clutch was pushed it the delay would start over again if u had it switch power off and on with the clutch pedal position.

 

the n20 delay is a feture inside the box. it has three or four dip switches to set the delay.

 

Not how u set it, but reset the delay after u make your pass.

 

The delay automatically resets after the RPMs drop below 3000

 

Exactly, as long as your car doesn't drop below 3k rpm's while shifting it won't reset the delay.

 

My TT is wired into my WOT switch not my arming switch.

 

OK, so the delay starts once u hit 3K then resets when drop below it?

 

To The Top

 

Nope the way the box works is that once your delay period is over when you go WOT, if you are at or above your lower window setting it will start spraying.

 

What resets the delay?

 

the delaY resets when you drop BELOW 3000rpms.i know this is old but i would like to know this too.

 

OK, lol, forgot about this post. Went over it saw how lost I was even after I got the answers to the ?'s I asked. Guess I didn't read it well enough.

So my final answers are : When you go WOT the TT reads it and then starts the delay. If the delay time is less then the time it takes to get to 3K RPM, it will then wait untill you reach 3K. (hmmm, kinda dumb, u have to wait till 3K anyway) If the delay time is longer then it takes you to reach 3K, then good. By that time you will be at 3200 or 4200 or whatever. When you finish your run, you drop down to below 3K and the delay will reset itself and wait untill you hit WOT again to start its countdown.

Makes 100% perfect sense now(if I understood u guys rite). Now this is real easy. I'm goin to Hooters for lunch now. I will draw it up on a piece of paper over there and then redraw it on AutoCad to post it for ya's. Is post holidays and kinda busy so might take a day or two to redraw it.

 

take your time.we all apreciate it.

 

Yup, got it figured. The only thing is that there are several ways to wire it up. What would be benificial for you guys is if someone had a scan or the wire directions for the TT and eithor posted it or emailed it to me. That way I know where they want/have you place the WOT switches, relays, and other stuf and in what order. Then I can draw it up so that you would not have to unhook all of it to rewire it up just to match what order I have it all placed in. I'll just show where to tap, split, or split and make it a lot easier for you folks.

 

You dotn HAVE to wait till 3000RPM you can set your TT to spray at a lower RPM. Not recommended IMO.
