DYNO RESULTS, reached 1.4 bar boost Options

[tufy]

we just finished mapping. we reached 1.4 bar boost after installing new greedy type R bow, 255 lph apexi fuel pump and 5 bar map sensor. i think now we are so close to 500 whp now or more. i am waiting for new injectors and fuel rail to go dyno one more time.

very nice tuffy!
what rail are you planning to use?

[snakeloa]

Where did you get the map sensor from tufy? What is this sensor doing exactly?

[playr158]

a MAP sensor reads the pressure and converts it into OHMS...
tells the computer how much boost/vacuum is being made

[snakeloa]

and what does the "5 bar" indicate. that you can go up to 5 bar? The usual OEM Sensor how much bar can this one handle?


Is this a must?

@tufy Where did you buy it?

cheers Joerg

"The Manifold Absolute Pressure (MAP) sensor measures the changes in the intake manifold pressure which result from engine load (intake manifold vacuum) and rpm changes; and converts these into a voltage output. By monitoring the sensor output voltage, the ECU know the manifold pressure. At lower pressure output voltage will be about 1 to 2 volts at idle. While at higher pressure or at Wide Open Throttle (WOT) output voltage will be about 4 to 4.8. The MAP sensor is also used, under certain conditions, to measure barometric pressure, allowing the ECU to make adjustments for different altitudes. The ECU uses the MAP sensor to control fuel delivery and ignition timing."

2 bar = 14.7 psi (oem i think)
3 bar = 29.4 psi
4 bar = 44.1 psi
5 bar = 58.8 psi

Ehm ehm...... Dan:

1 bar = 14.5037738 pounds per square inch

2 bar = 14.7 psi (oem i think)
3 bar = 29.4 psi
4 bar = 44.1 psi
5 bar = 58.8 psi

Next time - please check before posting

lol sorry i was out by .2
3 bar is now 29psi
4 bar 43.5psi
5 bar 58psi

i got the orignal #s off a quick yahoo scan
"1 Bar MAP sensors are used on NA(naturally asperated) vehicles.
2 Bar MAP Sensors are used on forced induction vehicles(Turbo & Supercharged). They can measure up to 2x the apmospheric pressure(29.4psi), so that means it can measure up to 14.7psi boost(the atmosphere is 14.7psi + 14.7psi from the turbo/supercharger).
3 Bar MAP sensors can measure up to 44.1psi, which translates to 29.7psi boost from a Turbo/supercharger."

thanks for catching that

now its better lol

[tufy]

very nice tuffy!

i am planning to use HKS fuel rail. but still i dont have prices to decide.
my tunner installed this map sensor. thanks doogy and playr 158 for info.
btw. i drived my car yesterday night. it was awsome. power is at little bit high rpms but once turbo spoools its very fast. its hard to drive. i have to made some more practice to improve my driving skills.

[urbandork]

wow i want one

[snakeloa]

@playr158 Thank you for your explanation

Ok then i willl have to get one as well. Where can i get such a 5 Bar Map Sensor?

@tufy what ECU are you running? Power FC?

yes i have power fc. ecu.
i just checked my old sensor. it writes ''sensor assy. turbo pressure'' brand is denso. 5 bar map sensor is also denso.

[snakeloa]

Thank you tufy!

Tell me do you use the datalogit or what did your tuner use to get the maps set right.

cheers Joerg

this is so wrong

2 bar is 29psi
4 bar is 58psi

[afroman]

i think what he is tring to say is that a 3 bar map sensor can read 29 psi of boost ans so on.

actually we are both right...your talking atmospheric pressure....mine is in turbo/supercharger boost pressure

"2 bar map = They can measure up to 2x the atmospheric pressure(29.4psi), so that means it can measure up to 14.7psi boost(the atmosphere is 14.7psi + 14.7psi from the turbo/supercharger)."
you have to remember turbo pressure is ABOVE atmosphere...so 0 boost = 14.7 atmosphere so when you read 14.7 on your gauge thats really 29psi...
make sense now?

he used his laptop to tune my car as seen in photos...

[snakeloa]

That is for sure But which program did he run on it "Datalogit" the "Excel" or any other Software?

ohh. he was using datalogit.
