Logging oil pressure w/LM-1: Thx Dean & Doug!
My LM-1 is now logging oil pressure thx primarily to Dean & DougRay; 2 VERY fine gentlemen. Very cool!
with a shim in the relief valve, it is hitting at bit more than 100psi @11k, using Mobil 1 15W50.
Thanks guys!!!!  sup: !!!!!!!!!
PS: since you are so helpful, maybe you can tell me why LM-1 Looger just quits sometimes???
Also, now & then the LM-1 just stops recording?????

Ninja12,
not really a big deal:
1. get a 0-100psi MSI WB762 transducer for logging oil pressure (about a $100)
2. get a brass T from home depot so you can run both the MSI and yr stock oil pressure sensor. (about $6)
3. hook the MSI up to 12V pwr and the LM-1 aux box (gnd & MSI 0-5V output)
4. load this table or one like it into Log Works
OilPsi Volt
0 1
100 5.0
5. start logging oil pressure 
This isn't perfect but is pretty close

Thanks,
I like that maybe we can spot a bearing going down before it can do real damage.

Glad to help, I'll hopefully try to log for the first time this Wed TNT. Along with boost, fuel pressure, RPM, A/F.
Thanks for the table values

look at em again
I hooked up the sender to a good qual oil pressure gauge, took a buncha measurements and found that the response is linear as hell.
Bottom line:
0 psi = 1 V; 100psi = 5V.
Pretty simple table, eh?

Thanks to a lot of help from Dave Owen, I am seeing everything correctly! A/F, EGT, Duty Cycle, TPS, and Air Box Temp!
Dave was 100%!!
