what happens when boost goes past the limits of a 3 bar map sensor on a f.a.s.t . aftermarket comp.? its the old style box......will it still work?
i need to run more then 30psi and the fast computer and map sensor are good to only 30.........i think.........please help!!!!!!

the sensor will be maxed out and the computer wont know how much boost its getting. Its kind of like having a MAF car with the MAF maxed out. You can trick it into fueling with the VE, but it can be a gamble.



p.s. a three bar sensor is good up to 28lbs

so i can keep it fat at the end of the table and the computer will go with the last VE settings? and as long as the car doesn't lean out under a few more psi it "should" be ok?

Thats alot of boost for an LTX (even forged).

Yes, it will stay on the last table it saw before going out of parameter.

Hehe sounds sick Jesse. Before we fixed my valvetrain issue my car saw 26psi a few times. :0

With the pt88 i ran it as hard as i could and it would hit 23-25 psi and was done after that. But with the t91 I will be surpassing that, and i forgot about the limits of the older f.a.s.t. units and I really don't want to buy a new system this year.

Get the updated firmware and it will be good to 5 bar. A number of companies make a 5 bar sensor.My 1.02 version has it .My unit is 10 years old.

They have a 3.5 bar sensor too. Probably more use for those that a 3 bar is barely not enough for, without losing too much resolution.
