Does anyone know where I can find this file? I just put a TPIS MiniRam (very similar to an LT1/LT4 manifold) on my ZZ4 and wanted to see the entire calibration for a 4th gen engine. I managed to find the spark timing tables and converted it into a bin, put it in my calibration and MAN what an improvement. The LT1/LT4 cal has to be a good starting point for tuning.

Thanks!

 

LT4 is an OBDII file. Do you have the ability to read this or just OBDI files?

I am not sure what the difference between the LT1 and LT4 files are but I can not imagine that much.

 

I downloaded some software that converts .lt1 files into .bin files for viewing on programs such as Tunercat.

As far as differences, I imagine that the LT4 has slightly more aggressive fuel/spark tables than the LT1 in order to take advantage of the better heads, camshaft, and manifold.

 

This only converts the file extension, not from OBDI to OBDII. Totally different events....

And the changes are nothing more than you can do on your own. but a guide is nice.

 

Actually, my goal is to simply see the numbers in the LT4 tables and simply do a cut and paste into my own calibration using TunerCat. I realize that the file itself is incompatible with a 7730 style OBDI ECM.

 

Unless someone has already done this the software you speak of will not allow you to do that.

LT1edit has 2 versions, OBDI and OBDII. (Now if you have both versions I am making an *** of my self....)
Tunercat will only view OBDI files.
