question.... is the safc1 and 2 that different from each other? Is there any particular advantage of getting one over the other?
Engine management... what to use W/ 1JZ

- Start date
safc2 has 12 points of tunning vs the safc1s 8 points.. the afc2 also has the ability to store 2 different maps files.

Exactly, if you have to rely on knock dectection for a safe tune, then something is wrong with the tune or the engine/fuel setup.

The safety feature is nice, but yea dont rely on it for a tune. But helps keep your engine healty. Logging the knock sensors is a great tool though. You can easily street tune your setup with it.

Alot of high horse power tuners don't even use the knock sensors, One of my friends with a evo II runs a Autronic ems & doesn't use the knock sensors, He hasn't blown any motor yet & has ran a best of 10.24 @ 142mph... Oh & that's with a master power T-70.
I have a knock sensor, actually I have two...... MY EARS!
Knock sensing is retroactive. If it detects knocking, it's because it's already knocking.

there is very slight knock that you'd never hear, but the knock sensor does..
Its just an extra tool to help get the job done.. do you need it, no.... is it usefull, imo yes..
Only thing I wish was different about the stinger is more aux inputs/outputs. Other than that I love the interface, and the simplicity.
Only reason I didn't use the MSII, and it may seem like a dumb reason.. I couldn't find an answer to if the MSII could read the CPS. I didn't want to fool with a trigger wheel.

Megasquirt is more like a high school science project then a standalone engine management system for your car.

MoTeC here, what is a KNOCK sensor? Oh you mean one of those thing to detect an event that has already taken place 
Knock sensors are worthless above 4500 rpm anyway, right when you are about to go into peak power production. To much engine noise to contend with.

I Agree with you, but those guys are Running VP import or C16 or higher right? Most of us run on 93 or 91, at that octane level and higher boost, im sure you would like your investment to be protected by everything gizzmo possible.
By the time you hear knock, the engine has already seen detonation or pinging.

No piggyback can raise the rev limiter. To raise the rev limit, you need a Mines, Gforce, or other reflashed ECU. Some piggybacks have timing control like the MAP ECU 2, and I believe the emanage ulitmate does as well. From what I have read, the timing control on the piggybacks is not very good.
