LA sequential fuel and spark EFI conversion

What would like to talk about it in particular?

I'm currently running the Holley Sniper TBI EFI on my 360 in my 67 Dart and use their PC based tuning software to adjust that, I've been getting pretty comfortable and proficient with it.

I'm very close to also starting my batch fired multi-port EFI system on my 440 in my 76 Ramcharger using the DIY Speeduino EMS which uses Tuner Studio as the software, a lot of the features look similar to the Holley software so there's lot of overlap in the setup. I'm planning on doing a write up on my 440 EFI install once I get it up and running/tested...etc...

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.
