i was reading an earlier post and a guy with the same problem as me brought up checking "LOAD SENSORS", such as the MAF sensor. What other load sensors are there?
other than moving the needle on the gauge, what other role does the turbo pressure sensor play? A/f ratio adjustment or anything like that?
also the same question for the T-VIS. i know it doesn't move the gauge but what is its purpose? thanks
the boost gauge is a load sensor.
load sensors have direct effect on A/F ratio....
The boost gauge does not have an effect on the A/F ratio.

Sorry, not familiar with that term.

On the Gen2 engines (the ones that came in U.S. turbo MR2s, the MAP sensor just controls fuel cut and the stock boost gauge. It does nothing with A/F.
On the Gen3 3SGTE engines, it is used for determining fueling.

The T-VIS blocks 1/2 of your intake valves (one on each cylinder) so you have more low-end torque. As your rpms build, the TVIS opens so all 8 valves are open and you can flow more air.
when the T-VIS opens up those secondary valves (runners), is it possable to hear it like v-tec for hondas? just wondering cause my problem is in the 4000 rpm range?
Because having the stock gauge standing up at full boost all the time is annoying/distracting to see. I always think something is spiking or overheating or something nasty.
I am pretty sure he already has a good boost gauge.

That is still incorrect as I explained in the rest of that post:
"On the Gen2 engines (the ones that came in U.S. turbo MR2s, the MAP sensor just controls fuel cut and the stock boost gauge. It does nothing with A/F.

The factory boost gauge is an ELETRONIC gauge, not a MECHANICAL gauge.
T'ing into the boost sensor will not operate the OEM gauge.
It does not have a boost/vac line running to it ... that is the whole reason there is a sensor in the engine bay. It sends an electrical signal through the ECU.
