Self Learning?

So I'm about to fire this thing off for the first time. It says that the temp needs to reach 160* before it will start to learn. My question is, what is it going to learn? if it's going to adjust the parameters of my engine specs based on how I drive what happens if I drive around in town for several days just doing 30 mph and then one day I want to jump on it hard. Is it not going to know what to do? Should I run it hard for the first couple of trips so it chooses a category that is more of a "sport" mode? How long does the learning process take? Will it always be in learning mode? I guess I just don't understand he full concept.

You can lower the temp that it starts learning. I have a 160* T-stat so I lowered mine to 150. It's under "Break Points"
My advice to you is to let it learn on its own for as long as possible. Unless your driveability compromises safety. I messed with mine too much and I think it wasted time trying to compensate for my changes. I finally did a reset, stayed out of the Pro Tuning section and only messed with the accell pump.

That's funny. I did similar with my Fitech LS. Thought I knew better. Reset defaults and learning and it has been happy ever since.

Yeah, you just have to be patient, the computer makes very small changes at a time. I think I read some guys weren't happy until they got a couple thousand miles on their units.
I was getting real close and then winter hit...

read the same thing, been paying attention to the sniper system. Do like the idead of self learning (pc illiterate) just not sold on it
Many efi conversions go back to carbs for whatever reason?

Sure once its right its pretty nice especially with the carb/ethanol gas issues. love the double pumper carbs but the fuel evaporating/hard hot restart stuff is real annoying EFI should stop that.

Learn works best for steady state driving with a fully warmed up engine in excellent condition with a properly done EFI installation. Learn keeps your AFRs in line for normal driving conditions. Google it if you need a long winded technical explanation.

If you drive nice, these things work out of the box for the most part. If you like to put your foot on the floor once in a while, you "might" have to adjust the accelerator pump shot up or down a little.

Firebob, don't worry about learn. Crank it up and enjoy it. Oh yeah, and if you had put Sniper in the title, I would have stayed out of the thread. Make a note of it. >:)

If it starts and runs and revs nice in the driveway take it out for a spin around the block. If it doesn't run smooth or rev in the driveway I would try to figure that out before trying to drive it.

I did a couple times around the block (regular 30 mph stuff) and it seemed to be OK, not perfect but didn't seem like it was going to stall. Took it back to the driveway for a quick check for leaks or other issues. All looked good. I found a spot less than a mile from my house that is a really long block square with 30 mph on 2 sides, 45 on one and the lead in to a 55 on the last side. The first day I must have spent over an hour going around that block. The 55 side was the most useful because I could hit it hard when I turned onto that section. After that it was 90% tuned and totally drivable.

If you are trying to do computer control timing at the same time I wish you luck. It just ads a lot more variables. If you have a stand alone ignition system especially one that was running on the same engine before I think all of us would highly recommend sticking with that initially. Once you get it running good with just fuel then make the switch to the ignition. That way if there are issues you know its ignition related, not fuel.

Steve: "Maybe I'm under thinking it."

Not likely around here. :) you'd be a thought leader with that. :confused:
