Re: H-I-J '76 Nova re-fit.
 

race pack (imo), if you use it all the time its great, but its a pain if you only use it once and a while ,, I have a RPM data logger and it is real easy to use and set up ,

your install is nice and neat,, mine started of that way but added a bunch of stuff ,, it got out of hand

Re: H-I-J '76 Nova re-fit.
 

and, how to react to the data it provides, the new learning curve.

Re: H-I-J '76 Nova re-fit.
 

Ding-Elexa ,tell me what adjustments to make for next round -ding

Re: H-I-J '76 Nova re-fit.
 

They are simply recording data from a run--"you" have to make any adjustments that you feel are necessary--- over time after reviewing the records you have been keeping of each run you will make the "correct" changes to your tune up to correlate a previous run mimic your next run-- you are going to have to enter additional info or keep the info in your log book such as track temp/humidity/grains/density altitude/ etc. to see what your car run in similar conditions---it is not an ET or MPH predictor--- FED 387

Re: H-I-J '76 Nova re-fit.
 

Racepak is great if you remember to turn it on so it records the run. At Indy driver forgot to turn it on in 2 runs cost him a class win. At Norwalk remembered to turn it on .2 quicker. He just won class at the Sports Nats.
Moral of the story if you got it use it.

Re: H-I-J '76 Nova re-fit.
 

There is a mode to start the racepak when it hits a set rpm.

Re: H-I-J '76 Nova re-fit.
 

Start with pg. 22 of the manual for rpm trigger setup. Section 5. That's a nice piece. Maybe start with pg. 1 :cool:

I'm trying to piece together Innovate Motorsports products for data as a Racepak is out of my budget. You have such nice stuff.

Re: H-I-J '76 Nova re-fit.
 

our grid will starts to log once it sees the launch rpm limiter activated and above 2500rpm which is nice and it ends up recording every pass we don't have the arc module to record output shaft or driveshaft rpm because of the legality around running it i wish they would make a driveshaft module without the built in traction control stuff for the grid.

Re: H-I-J '76 Nova re-fit.
 

hahaha

Re: H-I-J '76 Nova re-fit.
 

I'm sure this would happen. We put the button on the floor just to have it but fully intend to start recording off RPM.

Re: H-I-J '76 Nova re-fit.
 

This is exactly how I intend to do it.

Re: H-I-J '76 Nova re-fit.
 

I'm sure this will be a bit of a learning curve, thankfully Racepak has some great YT videos with full explanations. I think a lot of people just log with a tach, I've never had a Racepak and really wanted to tune without wrecking the clutch before I figured it out. Plus, my clutch guy's first question is always "where's the log"?

Re: H-I-J '76 Nova re-fit.
 

Well guys our test day was a total crapshow! I didn't organize this track rental, I got a call while we were at Indy from a friend and he was looking to put together a rental for the 22nd. All was looking good he had 10 people locked in and last minute a bunch backed out, from there for whatever reason the track pulled the plug without much communication. I would have paid more $$$ but I guess it wasn't meant to be. We'll be headed to GALOT this week and will test there, I just wish I would have had a day to dial this thing in a bit and learn the Racepak, then use the GALOT test to further tune.

Re: H-I-J '76 Nova re-fit.
 

From the life gets in the way files, should have left for GALOT yesterday but troubles at work look like we won't make it. Hopefully testing this weekend at least.

Re: H-I-J '76 Nova re-fit.
 

Don't you just hate it when work gets in the way of your drag racing?

Re: H-I-J '76 Nova re-fit.
 

Sorry you can't make it Todd, was looking forward to meeting you and understand a little more about running a stick and Racepak from a "beginner's" perspective. Jim Schaechter is a bad influence.

Re: H-I-J '76 Nova re-fit.
 

I almost QUIT!:D

Re: H-I-J '76 Nova re-fit.
 

We're still gonna try to make it to VMP next week. Jim is a hard working class racer!

Re: H-I-J '76 Nova re-fit.
 

All will be forgotten when the car make a .2 jump in the right direction. Cya at VMP

Re: H-I-J '76 Nova re-fit.
 

I'll add some slips tomorrow, not sure what happened but we went testing tonight and it picked up .40 from indy.

Re: H-I-J '76 Nova re-fit.
 

Clutch!

Re: H-I-J '76 Nova re-fit.
 

As you will see in the videos, the clutch is too loose so we may be giving up a little bit there.

Re: H-I-J '76 Nova re-fit.
 

We had a few issues last night, one was with the water pump, I think it was just a funky connection so it was an easy fix. I'm a total Racepak newb so that was a struggle, biggest issue was not being able to get it to record, I ended up laying a laptop in the car and clicking a manual record button in the program every pass. Clutch needs a tightening up for sure. Autumn said the car had no power in Indy, although it was better here (far left timeslip is Indy the rest were last night, we only ran 1/8) you can clearly hear in the video it barely pulls rpm up in high gear at all. More work to do!

Re: H-I-J '76 Nova re-fit.
 

if Your checking 02’s here’s a small tip.
Place the curser over the o2 graph then left click the mouse. There will be a slide to adjust the sensitivity. I usually set mine 25 to 30. Cleans up the graph and makes it easier to read.

Re: H-I-J '76 Nova re-fit.
 

Hi,Todd
I am a racepak newb also. Have only about 12 recordings
Are you trying to starting recording automatically or do
You have a manual start button.I have ours set up on a manual
Button.I Just press it after I get the top bulb light. I have a configure
File to auto start but I have not downloaded and try. If manual
Starting you can test without running the car. We have a sportmans
With 1 O2 sensor and oil pressure sensor added I can email you
A screen shot of where the record start selection is.
Hope this helps some
David

Re: H-I-J '76 Nova re-fit.
 

Thanks.

Re: H-I-J '76 Nova re-fit.
 

David, I have it setup to record off the button but it won't. I planned to set it up to trigger off rpm but I wanted to try it off the button to know it would work but NOPE, I must have something messed up.

Re: H-I-J '76 Nova re-fit.
 

I tried to attach a screen shot of setup location of record
Selection Don't know if it sent. If not PM your email and I
Can try to send it that way.

Re: H-I-J '76 Nova re-fit.
 

Is it normal to lose 8 mph between 1/8 and 1/4 ?That just looks wonky.

Re: H-I-J '76 Nova re-fit.
 

Yes, it’s very normal when backing out of the throttle....GEEZ. !!!!!! Autumn is doing a great job ....'!!!!!!!!

Re: H-I-J '76 Nova re-fit.
 

Well 1st- never said she wasnt doing a good job.2nd - never read where she was backing out of it.3rd GEEZ does that mean somebody peed in your cheerios?

Re: H-I-J '76 Nova re-fit.
 

In all fairness to you, I am still trying to figure out if this is a serious question . perhaps you SHOULD read the entire thread next time.....MJ doesn’t eat Cheerios .....

Re: H-I-J '76 Nova re-fit.
 

Yes, it appears mine is properly set up and I'm pretty sure it said to wire it to a ground source to activate, which we did. Hmmm!

Re: H-I-J '76 Nova re-fit.
 

We only ran 1/8 as I stated in an earlier post. Car doesn't pull through the back half well at all but it will gain mph, we're working on that.

Re: H-I-J '76 Nova re-fit.
 

Are you using the supplied switch with the kit or your own for activation? There seems to be slightly different wiring if you are using your own switch to trigger record. I'm kind of following along here with a manual, so forgive me if I'm off.

Re: H-I-J '76 Nova re-fit.
 

I used the supplied Racepak switch, wired to ground, checked with a simple test light for functionality. I'm sure I missed something and there will be an "Ahh Haaa" moment at some point.

Re: H-I-J '76 Nova re-fit.
 

I might be misunderstaning but how did you test
With the light. The input is taken to ground.
Or did you mean you tested the switch only . I would make
A long jumper and temp short it to the battery neg post
Once removed the racepak led should start flashing (recording)
If it doesn't start recording I would check the 12v and neg wires
Going into the recorder.
The simple things are always the hardest to find.
Lol

Re: H-I-J '76 Nova re-fit.
 

I clamped the test light wire to positive and stuck the "record wire", when I push the button the test light lights indicating ground. Also, I'll assume when the ignition is cut after the finish line it will stop recording when I get this sorted out? Now it records till I shut it off in the program.

Re: H-I-J '76 Nova re-fit.
 

I have are wired like this:
The red wire (C position) is connected to the ignition
"on" wire When the ignition is turned off the racepak
Is power down. You can set it up to stop recording when
Rpm drops below a set point for a set time amount

Re: H-I-J '76 Nova re-fit.
 

off topic a little i'm not familier with racepak but your 1/8th mile et shows low 11 second potential which would put you comfortably under your index if you can figure out why its falling over in high.
