AEM 3.5 bar map on power fc

I have a power fc on a evo V and want to tune the car at 36 pounds of boost I tried installing the 3.5 map sensor with datalogit and searched on this forum and found this scale numbers
AEM 3.5 bar 60300 Scale 7600 Offset

when I tried the numbers the scale on my power fc is only 4 digits not 5 like these numbers does any one have the correct numbers.

Oh and I have all the suporting mods
Thanks in advance

Solved it, I had to work 5 hours with vacumm pumps and voltimeters

I tuned the car to 35 psi, amazing, I keep reading on this forums people who say " Oh our shop car it tuned to 40 psi with this computer" and still no one answers a very simple question its ok maybe the right people have not read it yet.


oh and by the way dividing the numbers by 6.667 does not work

Not sure why this would take 5 hours. All that is needed is compressed air source, boost gauge, manual boost controller (to control pressure to map sensor) and a voltmeter to record map voltage at different boost levels. then just enter the numbers in the software. should only take about 20 minutes.

Probably the right people never saw it. The PFC doesn't get much play on EVOm. You should check out the Datalogit Users group on Yahoo for some great information.

Also, post your settings so we'll have them here for the future.

Map Sensor - 4 bar

PHP Code:
The PFC doesn't get much play on EVOm 
Yeah, it's too bad. It's big with the FD crowd.
To share some info, I too switched the stock 3 bar (less one atm = 2 bar or about 30 psi) to a 4 bar. I used RX7.com's map sensor and after fiddling with the vacuum/boost readings and plotting I came up with:
scale of:9830
offset: 4300
I'm still a bit off at the extremes of boost and vacuum when checking with an external gauge, but not enough to be concerned.
This map sensor isn't listed in their website, call Mary or Chris at
http://rx7.com/store/rx7/fdindex.html
As with all PFC tooning, you'll be better off with the Datalogit software to make the changes.
cheers
