LA sequential fuel and spark EFI conversion

Nothing in particular. Just throwing it out there in case someone has questions about it. Again, I'm no pro, but I can offer advice on what I've done so far.
I've never used the Holley system. How do you like it compared to Tuner Studio. I know you said it was similar, but do you think one is better than the other? Is the Sniper software different than the software they use for the direct port systems? I paid for the upgraded tuner studio and also Megalog viewer. Honestly, I don't think you will be able to dial in the tune without megalog viewer. I went for a ride to datalog several parameters and made a map with the data mimicking my VE table, only instead of VE values in the table (Z data point) I populated the cells with AFR. I then calculated how far off it was from my desired AFR and adjusted the VE value with the respective percentage. It was practically dead nuts after doing that. After I get everything close, I'll turn on AFR correction and let the computer do the fine tuning. It did a pretty good job prior, but was still jumping around a little since my table was so far off in some spots. It's nice actually seeing a steady AFR when driving.

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.
