7531 to power grid

Trichevy · #1 10-07-2011, 07:47 AM

Hi,
have at the morment the 7531 dgital 7 because i need the boost retard and the logging functions. For recording lamda and other thinks i use the race pack LDX dash and recoder.

I wont to interface the 7531 and LDX to have just one recording. So i so the new 7730 power grid. Very nice idea. I just wonder which one can write down the power grid with no inputs. Any way now my questions.

1. Can i use the 7531 with the power grid 7730?

2. If yes, can i use still the boost retard?

3. Will the aktual PSI pressure send to the race pack too?

3. Do you now a better posibility(3 X recoder ldx, 7531, and powergrid) to get a conection from the race pack to the 7531)

best regards from germany

1. Can i use the 7531 with the power grid 7730?

2. If yes, can i use still the boost retard?
yes, but we are releasing the 7762 boost retard module soon.
3. Will the aktual PSI pressure send to the race pack too?

i would call race pak on that one---909-709-5555

When using this harness and usug the 7531 for spark and igintion do you need to connect the orange, black, red, and white wire that normally would connect to the 7720?

orange to battery plus( so it will record)
and black to ground.

With this harness and using the 7530 am I have been told I need to run a wire from the harnes back to the 7530 for launch, burn out, and max rev limit and connect white wire from grid to white wire on the 7530 is this correct is there a diagram for this anywhere

because , your limits will have to be done on the 7530t-7531...
( because ..there is not a external rev-limiter input on the programmable boxes)

so, make sure both dark blues and light blue wire is connected ...
that way the grid will record.
