Most notable is the ScienceofSpeed FVM (Fuel VTEC MAP) Controller included in all stage 1 systems for 2000-05. The ScienceofSpeed FVM Controller is an electronic integrated device that has allowed load vs. RPM fine tuning of the fuel curve, the early engagement of VTEC for an impressive 40 lb/ft gain of mid range torque, and the required MAP sensor voltage control. The ScienceofSpeed FVM Controller is installed with the supplied plug and play wire harness adaptor which requires no cutting of the factory wire harness - another plus and consistent with our system's 100% reversibility design philosophy. Originally designed as an add on upgrade to the standard stage 1 systems for these years, we've made the decision to include this device as standard equipment on all stage 1 2000-2005 systems. All customers from the initial introductory sale to present have been upgraded to the FVM Controller at no additional charge.
How much control does this give you? What rpm is vtec set at? Can you run a higher psi pulley with this?

Can u guys sell the adapter plate so the novi1000 guys can upgrade to the novi1200 ?



please ???
AGREED! When the time comes, I would like to be able to switch over to the 1200 instead of having to buy a whole new system.

SOS, I suspect if you sold an adapter plate to convert the old Comptech setups to the 1200 you might clean up because there are a LOT of us out here.

Please consider? If it's possible, how much would you charge for the piece plus the new bushings and trick tensioner.

This is the kit I got and it will be here Monday (So says UPS anyway). It shipped today.

I don't see there being any safe way to increase boost with this upgrade alone. The stock ECU and fuel system is the limiting factor here. It should just allow for finer tuning of the fuel flow that is already available, and also lower the VTEC point. The stock VTEC points are too high even on the stock motor in my opinion. I think Honda sets them artificially high so that customers "feel" the VTEC transition. On a supercharged motor, that transition is even more pronounced. Check out the dyno graph of the beta stage 1 cars and you can see the massive spike when the VTEC switches. If I remember correctly this FVM controller lowers it to somewhere around 4500 rpms. That should give a very linear gain in power. It might feel slower by the seat of the pants because there're no surprises, but the fact is you'll probably gain upwards of 40 lb/ft right in the midrange.

I'll post my dyno sheet as soon as I get mine dynoed.

Thanks,

Was hopeful this system would at least handle 7.5-8psi since the stock vortech system is in this range with an fmu.

I understand that part. I'm just looking at the specs on your website and they say stage two is 9.5 psi. You'd probably get more stage 2 interest if you didn't have the k-pro on there since it is not needed. This would bring the price more in line with Kraftwerks high boost kit which runs about the same psi and whp but $500 less.

Actually your stage 2 description for the 06+ just confuses me. The description doesn't actually describe anything and calls out parts that are already in the base kit. 650cc injectors for exampe. The base kit is 8.5psi, but the description for the stage 2 is 9.5psi. IS the stage 2 for 06+ 9.5 psi? If it is remove the k-pro. The $1500 price tag for stage two isn't worth 1 psi.

Now if you had a high boost kit running 12psi or up, then I'd put the K-pro on the kit.

I'm not trying to start a fire or anything, I just can't quite see the reasoning behind it.
Sorry, I may not understand your question. The standard 06-08 kit produces roughly 8-9 PSI based on environmental factors. This will produce 360-380 wheel horsepower based on a number of factors including dyno, exhaust system, etc. This "stage 1" 06-08 kit produces roughly the same amount of power as the Kraftwerks kit but is $500 less. Our standard "stage 1" system is equivalent to the Kraftwerks "high boost" setup. Both systems use the Hondata reflash tuned specificly for each company's system. The only difference being the pulley size. I believe all these vague names may be confusing the issue.

The Stage 2 system would be ideal for a customer with a built engine, running more than 10 psi, that requires programmable engine management. If you need further clarification, let me know.

regards,
-- Chris

The ScienceofSpeed FVM Controller is a device with fixed fuel, VTEC, and MAP calibration. It is not designed or intended to be used with a higher pressure pulley. For this, we recommend our stage 2 systems. The VTEC with the FVM is set at 4200 RPM from the factory 6000 RPM change over point. It is the point at which the VTEC change over produces the smoothest torque band.

You are correct. The factory tune is set artificially higher for whatever reason the factory deemed. I'd agree that it was likely a marketing decision for "VTEC". It is not uncommon in the OEM world, Nissan and other manufactures specifically tune engines not only for power and emissions, but for a certain characteristic that are synonymous with the brand.
