HOM?
I am patiently waiting for my stage 2 to show up but i have one more question i havent really seen asked...In order to use HOM i need either race gas or a octane booster w/alky injection?So what im wondering is if i put 6 gallons of 104 octane in it does that mean i have to have HOM enabled for the car to run right?Will the car run on race gas without hurting anything if the lil RED button isn't lit up?Heres the scenario if i go out on a friday night for racing,i put 6 gallons of 104 in it and have the HOM on all night.At the end of the night i still have 104 in it but im not racing anyone,what will i need to do to make sure i dont hurt anything???Sorry for the long ? but i cant wait to get it and i want to be prepared for what im getting myself into...thanx for any input

RE: HOM?
Ok, I have stage 3 with toys, my HOM works just like yours on stage 2. If your running good octane gas, and you enable HOM (Red LED ON) and go run the car, the computer advances the timing and gives you more power. You have no need to worry about damaging the car at all. If the computer senses detonation, it will automaticly kick you out of HOM, this will be evident with the LED flashing red, and the loss of power felt through the car.
The computer will protect the car from any damage. Try running 91 octane gas and engage HOM, the car will run, but once you hit detonation, the computer will kick you out of HOM immediatley, and probably bless you with a very loud backfire.
If you have race gas and chose to run without HOM engaged, the car will run just fine, however you won't be getting the advantages that it was made to benefit with the race gas.
Another recommendation, depending on what octane gas you can get at the pump 91-93, you can also try filling with 8 gallons of gas and droping in a bottle of NOS racing formula octane booster. You may, or may not be able to run HOM with this fuel mixture.
I personally have a w/i set up with my stage 3, and with 8 gallons of 91 octane and a bottle of NOS racing formula octane booster, I have been able to hold HOM.
Bottom line, if you have good high octane gas, run the car in HOM, even if your not racing it, it will run much better.

RE: HOM?
a direct answer to your question - no you don't have to have hom enabled even with high octane gas in the car. the car will be slower if it's not, as the timing will be retarded and higher octane gas is harder to burn, so you're better off pressing the magic red button, but no you don't have to.

RE: HOM?
OK, OK,.... let's talk about octane. This seems to be one of the least understood concepts.
High octane gas is not some "super potent rocket fuel" type of gas. In fact, it's quite the opposite. Here's the skinny - believe it or not.
Octane actually retards the burning of gas. It makes it less volatile.
"What would be the benifit of that", you may ask. The benifit lies in timing... With high compression (or artificially high compression ie. turbocharged / supercharged) engines, gas that is not stable enough will ignite too quickly from the heat / friction of being compressed. Sort of a "flash-in-the-pan" type of thing. This causes the pressure of the combusted (and expanding) gas / air to whack the still open valve like a hammer, causing lifter knock. It also sacrifices power b/c of the short lived pressure it supplies to push the piston down. The more stable, slower burning gasoline, first of all doesn't ignite until the spark is introduced, and secondly gives the piston a nice long push throughout it's stroke. More power, more torque. With this being said, High octane gas will never hurt any engine, only radical low octane can do that. The only downside to not running HOM is the waste of expensive gasoline.
