Attesa Clarification

[r31slpr]

I'm helping a mate who's wiring an ecu in and he's stuck at the attesa tps signal.

I've found conflicting information on what the signal should be. Some r33's might be 1:1 with tps signal others might be 2:3?

Then I've also seen 3:2 instead of 2:3

So should it be 4.5v at tps & 6.75v at attesa?

Or 4.5v at tps & 3v at atessa?

Why not power it up and measure it?

Standard ecu is dead as. Looks like water damage so it went in the bin

R34's are 1:1 

32 and 33 are around 70%, I think it was 3.7v to the attesa ecu for 100% throttle.

Thanks heaps mate, everything I found said 2:3 which would have had too high voltage at the attesa ecu

I think the 2:3 ratio was written backwards by someone and requoted by others. Should be 3:2
