No playback tach.....

[Straightliner]

How might you recommend figuring out shift times without a playback tach? I'm looking to keep the learning curve time to a minimum, as my track is 3 hours away!! In my head I'm visioning me going down the track with a stopwatch in my hand!!! Turbo 400 in the car.

On a different topic how do you turn off the throttle stop if you want to bracket race all out? Will I need to change timer settings to do this?

Thanks in advance, Sorry if some of the answers are obvious, I do search before I post.

Well you could put a video camera on the tach and make a couple of passes and watch it with a stop watch. Don't be surprised if the one-two shift happens quicker then the two-three shift.

To run all out, I set all four timers (on-off, on-off) to 13.00 or any convienent time that exceeds your ET.

Hope this helps

Thank you Bill. I find it hard to find Throttle stop help stuff through Google, I don't want to become an annoyance, but I have a lot of learning to do and I hate to have to use an actual race to do so. I would be first round fodder for sure!!!!

Your welcome.
What kind if stop are you running?

If it's an inline cylinder type make sure that the pedal has a solid stop, if it doesn't it can drive you crazy!

If you looking far an inexpensive video camera try tigerdirect.com

if you had a mega 450 box, you could record your run to find the shift point then use that time. also w/ the 450 you have two screens, one for bracket, one for pro, that way you do not have to wipe your t-stop time out going from one to the other...

Bill- #1 stop air. But I do have a pedal stop already. I'm coming from 10.90 with no electronics.

Keith- I have a Dedenbear lightning, It's my understanding that it has a button to switch from pro tree to sportsman tree and remembers all settings for each. I have yet to run the car with the electronics. I have this fear of it shifting too late, but I guess that's why we have rev limiters!!!!!!

OK, here is a suggestion then. put in the time you think, watch the tach, if it doesn't shift before you hit the desired rpm, shift it by hand, continue till you have it zeroed in...



as far as your other post about some that leave w/.000 in first timer.
it takes about .020 (not sure of the exact #) for the t-stop to close. so it is not really .000. this maybe helpful for a VERY hard leaving car that does not want to pull the wheels out of the beams.

[Straightliner]

Yeah good point. Thanks.

Hmmm my car yanks the wheels out of the beams, I had to drop lots of air out the front tires and run the .03 button and I still go red if I try hard!!!!! I might experiment with that.

Another question guys- When t stop racing if the stop comes on before the 60 ft timers is that a big deal as I'm so used to looking at that number for consistency. Does that question even make sense?!!!! I don't think I worded it right!!!

[Mickey Whaley]

just sell ur old tach and buy a playback tach if u can pull to the track u can do that and yes if u put the throttle stop on or off before the 60 ft you will get funky 60 ft times so i guess if u are going to spend the money to go to the track spend it on **** that gives you info

[Straightliner]

Mickey, you're right!
