Here are the calibrated settings for running a 4 bar map sensor. It's good for running 43 psi of boost.

Scale 65535
Offset 4300

You can buy a Greddy 4 bar map sensor from Rotary Performance www.rx7.com . It hooks up to the same connector as the GM 3 bar map sensor.

I think it's the same pressure sensor that comes optional to the Greddy E-Manage Ecu. Greddy 3.0kg/cm2 PRESS SENSOR (Part# 16401301)

 

Got the scale and offset entered in today. When car is off, commander reads .01 for vacuum. It fires up and runs awesome.

 

this sensor wouldnt affect my current tune correct? im lookin into ditching the stock map sensor...

 

What are the settings for the 5 bar?

 

I searched a long time for the 5 bar settings. I finally went with the 4 bar because I was given the settings.

 

i only see the 3 bar on rx7.com.

 

You have to call and ask for it...... Call and ask for Chris or Ari.

 

how much boost are you guys running. the 3 bar is good to 29 PSI.

I used a mighty vac to test my 3 bar at Vac, ambient and 14.5 lbs. I adjusted the values to get them to match exactly with my stock sensor at those points.

Adjust the offset to get the vac reading to read close, and then adjusted the scale value to get the 14.5 psi value to read the same. It worked great, car ran exactly the same with the new map sensor.

 

I'm going to tune for above 30psi feb 4th.

 

^damn!!!

What are your expected ET's with that much power?

 

12.9@140

 

^I think I'm going to have to call BS.
<o:p></o:p>

Now I'm no drag racer nor have I been through a 1/4 mile enough times to really know what I'm talking about. So bare with me. But the stock car does a 13.9, I ran a 13.1 limping the clutch. Another run done the same way I got like a 13.8 and I missed third on that one. Both times my trap speed was about 117 or so. I never said I was good.

So how can you only be looking at a 12.9 especially at 140?<o:p>

Sorry just questioning the authorities.

 

because I drive like grand mammi..........

 

i think it means he wont be hooking up very well, but the power he will be making will be shown in the trap speed

 

^ahhh, I see the light. I should have checked the time slips tread before I said anything.

LUPE beat my best 60 foot time by a good second or so. I was around 2.6. I need practice.

But anyways back on topic,
Nice 4 BAR MAP Sensor.
