Hi all,
Just thought I'd pose a quick Q to anyone with in-depth knowledge of the T-VIS system.
I know its supposed to open at 4200RPM on the '91 3SGTE according to my BGB and about five million google search results. However....i linked an LED up to the pin on the ECU to monitor it and mine opens at
2000rpm. On the dot. Whether running 99 RON or 95 RON. After a reset ECU its the same.Also, fuel cut is supposed to kick in at around 12psi, and always did with the old CT26 turbocharger. Having swapped to a CT20b (from the '95 engine) i now hit fuel cut at 15psi.
Can anyone enlighten me?
J
