Is there a way to add more than 8 gauges on the, main gauge cluster?

Thanks

Hello
is there a maunal for Tunerstudio? there are way more functions than the megatune using a MS1 V2.2, why is there not a manual to figure out all the aspects of this?
Anything other than pushing F1-very vague

Just a question:

Is it best to add a ground from the engine block to one of the three sensor ground inputs on the relay board, to reduce noise in those wires (tps, coolant, air) ?

These three sensors all run to pin 19 on the DB37.

Thanks i would love to know the answer..

If you are using a relay board, can an additional wire from the engine block go to the sensor ground on the JP1 terminal for the coolant, TPS and air?

So as i see it here are my questions;
using a relay board, MS -1 V 2.2

1. Does the sensor wires need to be additionally grounded to the engine block and as well brought to the relay board terminal strip JP1?

2. Should the cable from pin 19 on the DB-37 cable be grounded to the engine block? ( the ...

Ok perfect, so far so good, if i use the main ground off the relay board to bring all the engine block grounds to, will this ground be sufficient to ground the relay board and megasquirt, the DB37 i have is the DIY autotune cable as I had trouble with my home made one.

When you are saying grounding ...

Trakkies, awesome, thanks for the info, we will work on the scope and check all the grounds.

So I should put all the grounds for the sensors and put them together to run to a single wire to a grounding post, the same post that is the ground for the MS controller?
Do the grounds still go to the ...

Anywhere specific the ground should go on the db37?
I have the TPS ground going to the relay board

The TPS has a clear and proper reading with the key on 'run' position, engine off.

With the engine running on 'run' position the TPS reading on the signal seems to be reduced:
- small blips of the throttle are not seen on the display
- when the throttle is around 50% i will only see maybe 10% on ...
