Speeduino PnP Not getting the target timing
 

Hello,

I've running my speeduino for about a year now. Recently Id turboed my 91' 1.6 and started to tune it myself but then I realized the car is not hitting the target timing, for example if Im targeting 18 deg in the Spark table after a logged pull I get like 8 deg.

Im not sure if it may be the problem but I dont have de VTPS yet, running a resistor in the tps plug.

here a screenshot of my Spark table and a 3rd gear pull log,
