for the PCM to pull timing, it has to "hear" a knock signal from the sensor. This means the engine has to knock 1st. do this long enough, often enough, and bad things happen.

BTW, the stock PCM is always pulling some timing, even at idle from the knock sensor input.

I'm guessing then that the Vortech kit's timing is more accurate than Comptech then. Maybe accurate is not the word, but maybe Comptech pulls timing a little more, maybe not pulling it optimal because the knock sensor will always be picking up knock, not necessarily from combusion itself.

The Comptech uses no additional timing control. It relys on the PCM to do its job.

The Vortech uses a more active form of timing control, that offsets the crank position sensor input to get a corresponding timing control change output to the coils.

Just beacause the PCM is pulling timing a idle, doesn't mean the engine is knocking. The PCM is always making adjustments to the timing. It's not really a conventional way of doing things.

hmm...i dont feel safe with just have the sensor pulling timing when knocking is nearby. Anyone run a vortech timing control on a comptech setup to be a lil safer on the timing aspect?

and that is why i like vortech ... cheaper and higher potential

I bought Vortech because I got a smokin' deal at the time and it was available with the aftercooler. I liked the idea of having an A/C. It was much cheaper than the Comptech without their A/C and I wasn't confident that they had resolved the problem with the cracking bracket.
If I were to do this all over again, I think I would go with Comptech A/C kit. I have visited the Comptech factory and those guys give the impression that they really care about the customer and they have a genuine enthusiasm for performance vehicles. Vortech, on the other hand, has truly CRAPPY customer service. They will NOT return emails and telephoning is a hit and miss affair. I despise any company that will show no concern for after the sale customer care.
The extra money paid for a Comptech buys that "customer care", approachability and it buys a dealer network that is well established. IMO, this is money well spent.
If money is an issue for you and you don't mind being "left alone" afterward, then go with Vortech. Both kits will work well on the car right out of the box.

good question Osama. I would like to know that also.

There is no reason why you couldn't.

Again, why did Vortech choose to spend money on a timing controller?Any special reasons?

The timing control unit is a Split Second unit. As to why Vortech included it I guess they perceived a need and Comptech didn't.

I haven't studied the compressor maps for either SC, but if the Novi 1000 is more efficient at it's lower boost (around 5.5 psi) than the Vortech SQ is at 7 psi then perhaps Vortech R&D experienced detonation whereas the Comptech crew didn't. This is just a hypothesis BTW.

Also, I'm not sure the AC is even needed. I ran my Comptech without AC for a year and even tracked it running 8psi (and E-manage) and didn't have a problem . I expect that the Vortech kit having it generates a perceived need and hence Comptech had to offer it.

Personally I prefer the Comptech kit. It is easier to install (electronics and oil drain), has comparable performance with less boost, and is made by a company that specialises in Hondas and Honda racing and stand by their products. It seems to be made up to a standard not down to a price. YMMV.
