Is TPS use for WOT by 993 Motronic?

[mmasse]

I am working on the tuning of a 993 engine with a TPS Supercharger with an Unichip piggy-back installed

I was testing the TPS voltage range and I am having trouble getting more than 4.3Volts as maximum WOT voltage.

I wonder if anyone knows what's the WOT threshold used by the Motronic. I mean, as from what TPS voltage will the Motronic consider that the engine is running at WOT?

Is TPS signal used to trigger the WOT fuel and timing maps on the Motronic, or only MAF input is consider for load input?


My concern is that if WOT threshold is 4.5Volts, for example, the WOT will never be triggered.

Thanks in advance for any help on this.
