Because they are ALL JUNK….an they know it an want fix it….Maddox can send it to place I was recommended on here….but buddy just got is back an it’s still doing it…. |

| Maybe off base here.Have some experiance but not ton with racepak. Any chance the reading you are getting is from the run and not what is happening at that momement until you switch it? Do all of the other readings change while you are looking at temp? Asking because we never used our to read while in pits just to record track data. Also have not had water in eninge since 1990, so never had water to read temp on.LOL

Is this a IQ3 Drag recording dash? If so do the recordings agree with the dash readings? Did it work OK last year or this all new setup? |

| Yea, you can change it to a button or a different RPM or Drive Shaft RPM which works pretty nice as well. I'm looking at the parameters as I'm typing and I think you could hook it to you line-loc by adding a relay to send a ground signal. Unfortunately, you can only pick one trigger. |

| This is not in response to the OP, but I thought I’d put it here just because. Here’s a way to create a record signal with several options using Analog ignition. This is drawn with negative trigger output but can be made to output positive trigger as well. The wiring diagram shows how to wire with a relay to start recording with either a remote momentary Push Button pushed or the Trans Brake button pushed. This way you have the option to start record at any time prior to using TB solenoid output. If you remove the relay wire from terminal 85 going to ground and attach it to the RAS (Rpm Activated Switch) output on your Analog ignition box, install a rpm chip in the RAS slot slightly less than the launch rpm it’ll start the record only when both the TB solenoid is energized and engine rpm greater than the RAS chip. This way, if TB solenoid energized is needed to back up or if you bump the TB button and the engine rpm is not greater than the RAS rpm chip, it will not start the record feature. |

| Pretty cool markemark. However depending on number of sensors a Racepak logger takes 2-4 seconds from log trigger activation to actual recording so it would be likely to loose some data with this technique. If you change your drawing to show line lock or burn-out input then that's the method I'd recommend. |

Greg, Thanks for the heads up as I’ve never used Racepak and wasn’t aware of this. The systems I use are immediate recording and program for 20 seconds to keep the download file as small as possible. I also have a virtual switch on my digital dash to start or extend a recording when desired. |
