That sounds so wrong Mark. LOL.

[lun40119]

I will Mark.........once it is working it seems pretty nice. The Data aquisition is dumb though. It triggers off rpm and/or an output like tbrake or linelock or brakeswitch. And shuts off when you shut the car off. Also the MSD Review is different. Ill keep working on it.....

[slimbo5]

Yeah. I already drew uP a schematic of how im gonna wire everything. I have to use a second relay to reset the blue wire via my nitrous micro switch since I don't use a t brake. BEcause I'm going to use the window switch built into the 7730 to turn my nitrous on. It will also work as a digiset to delay it as well. the second relay puts power to the blue wire via my nitrous arm switch and then when my micro swItch activates it removes power from the blue wire starting the timer/recording in the 7730. Only thing is I'll have to disable the nitrous and unhook the retard activation wire for it to log n/a runs.

[lun40119]

No......you can change the input to data log. You can set it to start logging when it turns on, or to activate at any rpm without an input.

[slimbo5]

Hmmmm...ok but I still have to use a second relay to reset the timer for the nitrous activation. Good to know I can start recording a different way. Time for a racepak this winter. Data is priceless.

[lun40119]

Racepack will plug right into this. I think the Grid controls up to 5 nitrous solenoids too.....tells them when to turn off and on. I have my Datalogger set to turn on off my line lock and 500rpm. So, it will start recording at the burnout when I push the button. And it will stop recording when it goes below 500rpm. Or it gets to 300 seconds.

[slimbo5]

Yeah jake but your using the blue wire to turn the logger on correct? When you remove power from the blue wire then the timers start for nitrous or time based timing control.
