I have my car tuned on Neptune (not RTP) and I'm using the RTP software on my laptop to datalog. Obviously I can't modify the tune or any parameters because I don't have RTP.

My question is, do I need an .ncl (calibration file) to datalog all the data? Things like MAP sensor aren't showing up, I'm assuming because Neptune has no idea what MAP sensor I'm using.

My tuner did this car like 3 years ago, and I'm sure doesn't have the .ncl file anymore so could anyone throw together a .ncl file for a motorola 2.5 bar map and precision 680 injectors so I can give it a whirl?

I obviously don't need a "tune" just a set of parameters so I can read the correct MAP readings for my datalogging/troubleshooting.

 

You need a hulog to datalog with. Or you can actually purchase and RTP and have a authorized netptune dealer copy whats on the chip to the RTP.

 

Map sensor is the only thing it needs to get from your tune file. Simply create a new file and choose the correct sensor so it can calculate it.

 

I am using a hulog. I have it hooked up and working great, it just doesnt read the MAP values. The problem is that I don't have my "tune file." How do I create a .ncl file then?

 

Create a new file by choosing New from the File menu.

 

Haha duh. Thanks man.

 

No problem.

 

Side note just out of curiosity. How does it know the duty cycle if it doesn't know the injector size? Just measure the difference in time between the on/off?

 

The fuel value is directly related to injection time.
