Ecotec 2.4 LEA tuning - possible with HP Tuners?

[garth285]

Hi all, not new to the ECU flashing side of things but I can't seem to find any info regarding the tuning of a Ecotec 2.4L LEA engine. I am going to be working with a 2013 GMC Terrain possibly and would like to figure out what I can play with in the ECU and possibly move towards a small turbo setup set for economy improvement not really for the power. So does anyone have any info about the LEA tuning?

Thanks for any info!

Did you find a tune for your terrain?.. I have a 2014 Equinox with a LEA, I'm interested in a tune for it to get some more power

Also interested to see if anybody has played with these. I have a 2012 Equinox and 2017 Terrain that could use some love.

I would also like to know. I have a 2013 LEA 2.4. It's not on the list but 2011 is. What's the deal there? Purchasing the HPT setup is what I would like to do, for other projects also, but not if I can't use it on this one.

You should be able to tune those, finding power and Econ is dependent on the individual vehicle when done properly. Torque management and timing are a few places to start. To be accomplished properly a wideband and the corresponding histograms need established for proper data logging.

Any update? I was able to advanced the timing by a few degrees and threw it 91 octane. Rarely any knocking. I need more power tho
