LA sequential fuel and spark EFI conversion

I actually like the Holley system better, it's very intuitive once you figure out a few things. I do know the Holley Sniper version of the software is a little tamer than the full blown Holley EMS system as that has a more options for customization. I like how in the Holley EMS anything fuel related is in it's own side bar grouping as well as anything timing related and a few other parameters like system settings. With the Holley system you can look over your base tune and the learn table in seperate tabs and you don't have to apply the learn table until your ready, so I find that handy to be able to compare settings. I haven't played a ton with the datalogs as I was having issues getting them to save through the PC software, I had to re-attach the handheld to be able to send a tune to Holley to troubleshoot my 02 sensor (it went bad somehow).

Tunerstudio has a similar feel and finding things is pretty easy based off of the row of buttons across the top and the sub-menus associated with each one. I paid for the upgraded version of Tuner Studio to be able to use the auto-tune function, I would like to try out the Megalog feature as viewing and using datalogs can be quite handy. I've just gotten use to making changes on the fly and figuring what to do but would like to expand my capabilities a little. I'll have to try something similar to what you did.

Might be fun to start sharing tunes and seeing what everyone is using for settings or for fine tuning. I'm no bracket racer or anything so I don't care who looks at what I have going on. I'm in the middle of optimizing my tune again after the 02 sensor replacement and that can't happen til I get my valve body back in my transmission.


I was trying it without the megalog viewer, but some things aren't noticeable enough changes for the human eye or ear to pick up. Also, there are way too many parameters to keep track of without it. I really wanted to dial in my idle and the megalog viewer really helped with that. There are some finite controls for idle timing so it helps to look at those values close up when trying to smooth out the idle.
I have no problem sharing my tune if someone wants to duplicate the components I have. Obviously there are several variables that will change the VE and timing table, but at least the basic setpoints can get someone started if they need help.
