adx for Marelli P8 (Lancia, Cossworth, Fiat)
Anybody tried to make an adx for Tuner Pro v5 for the Marelli P8 ECU from Lancia Delta or Fiat Coupe 16v?
Ok, i started with an adx, 8bit values and lookup tables are working but i have some troubles with 16bit values. Anybody know how to connect two 8bit values from different requests?
To be more clear i have to send 1 to the ecu and get back the MSB for Engine period, then i have to send 2 (literally the value not the number which would be 0x32) and get LSB of Period. How to connect??
BTW i think i found a small bug in v5, i can't enter negative Values in the Lookup Table.

value 1 (most significant bit) = 8 bit value, equation = x
value 2 (least signifcant bit) = 8 bit value, equation = x
value 3 = 16 bit value, equation = a * 256 + b, where a is output from value 1 and b is the output from value 2.
Give it a shot.

Ok. Got it so far, works like a charm. But there is one Problem left. TPS Conversion is:
if Degree < 30
Degree = (Data*0.1848)-1.41
else
Degree = (Data*0.7058)-90
How can i implement this??
I figure i can calculate both but how to compare?
Another Question i'd like to share this adx, where can i upload it?
Thanks for all the help and a really great piece of Software.

A near future version of TunerPro will be able to do this. You can send me the ADX, along with the vehicle information that it applies to.
