Bit of a newbie, but I've got a few questions about tuning via Megasquirt. I think I've got most things pretty good, it's running decent, but I did have a few questions.
My first question is regarding some low VE numbers in my table. I started with the base map provided by Brain (Thanks again), tuned my injector dead times based on the forum post here (Strange Results of Injector Change
), finally calibrated my battery voltage to the injectors which helped things, but I'm noticing my VE table numbers seem low compared to others. My req fuel is currently 4.1 (running DW700 injectors) and I'm hesitant to drop it lower as that seems to cause higher cells to start running a bit lean, but the numbers near idle do seem low. Should I care? Am I losing resolution by not having these numbers around/above 30's?
94 Engine (1.8 swap, complete with TPS, IAC, etc)
FMII Turbo Kit (GT2560)
My next question is regarding acceleration enrichment. I think most of the instructions on acceleration enrichment have to do with an older version of MS, TunerStudio, or both as it's a bit unclear as to whether or not I'm using TPS or MAP enrichment or not. I think I need to increase my acceleration enrichment as I do seem to be going a little bit lean when I hit the gas, but maybe I'm worried about nothing.
My last question (for now anyways) is regarding wiring for sequential injection. I understand the basics, but I'm trying to avoid running more wires through the firewall if I can help it especially since I have a bunch of spare wires from things I removed (purge solenoid, power steering wire, also did a coolant reroute so I blocked off and deleted the front coolant thermo switch). I'm wondering if I can use 2 of these wires for my sequential injection, or are these wires too small? I'm guessing if I pick wires too small I'll see a voltage drop that could cause issues (maybe the voltage drop may mess with the dead/opening time?)

I'm also not running an idle VE table at the moment because I'm not quite sure I need one or what the exact purpose is (I know, it's a ve table referenced during the idle state, but why that's different from the standard VE table is a question), but I can probably do some reading and figure that out...
I've also attached my tune. Any advice is appreciated, thanks guys!
Here's a log from a drive I took a little bit ago (though I did modify my VE tables just a bit since then to smooth some things out): http://1drv.ms/1Nv0clA
