Lm-1 and Lma3 Data Logger ?
86 S/C 5-speed:
I have been playing with my car again and have relocated the Maf under the fender. I found a couple of interesting things, the Maf was custom built with adj pots to change the base line. With it as a blow through the car ran well 7 Lbs of boost although a minor amount of surging during a steady drive A/F rations good. With it relocated it was running rich 12.1 at idle with no oscillation of the A/F gauge as expected. It stayed rich through out all driving ranges according to my gauge a Data logger.
Which gets me to my question on the Data Logger, The car sat for 3-months while getting the paint done and the memory dropped on the Lma-3. I cannot find my notes for the set up and tried using what I thought was the factory suggestions for settings. Wow my car now is running 8,600 Rpm's and 12.9 Lbs of boost in second gear, talk about cheap power
. Well I need to know what the settings would be for the Lma-3 and for the software dial tables. I remember to get the gages to indicate the correct settings there was some type of custom look up tables that are gone from my computer.
Set up of software
0-A/F
1-Rpm
2-Boost
3-Inj
4-Maf
5-Accel
Any help will be appreciated.

Thanks, but I have the manuals, I need some custom settings from the input table that are specific to the 928 or at least to get the boost gauge to work. I believe I received the settings via the phone but its been so long I don't remember. Good news is, I think I figured out the Rpm, it needs to be set to 4-Cylinders for our 928. The car ran good after the relocation, now as I set up the A/F by adjusting the Maf I want to make sure the information is accurate.

Is the idle voltage off of the Maf at 2.7 volts; with Maf adjustment I just did, under boost it's leaning out so more tweaking to do.
Where should I connect my meter to the NB to get this reading, my notes are missing.

Still trying to get the boost gage to read correctly on the software, this is what I have tried:
2-Bar
Psi
-14.70-0 Volts
29.40=5 Volts .5 expanded.
This will not give a correct reading I would like to see the Vacuum reading and at 0 crossover over to start to show boost.
Any help form you Data logger guys I tried Psi, Psig, Psia, Kpa, Bar
