The new VCS3G Alcohol Injection Controller by Labonte MotorSports

[dlabonte]

Labonte MotorSports is proud to announce the release of our next generation Alcohol Injection control system, the VCS3G. The VCS3G is not just another progressive controller; it is a fueling computer for alcohol injection. The advanced control algorithm uses Injector Duty Cycle (IDC) and Boost pressure to calculate precise injection control based on the vehicles BSFC (Brake Specific Fuel Consumption). This results in the most accurate control of alcohol injection leading to maximum horse power gains.

Though the in-cab touch screen display the user can use the Gain adjustment to dial in Air Fuel (A/F) ratios quickly when tuning for Alcohol Injection. Real time data for IDC, Boost and Injection is also shown on the dash mountable display.

Additional Features include:
• Advance system diagnostics and error reporting
• Auxiliary 12V 3amp output for Nos or solenoid activation
• Input for fluid level switch.
• Input for optional Injection Fail Safe (IFS-10) that allows real time display of fluid injection rate and warnings if IFS detects an injection fault
• Flash upgradeable software by RS-232 connection
• Peak and Hold display of maximum IDC, Boost, and Injection
• Easy upgrade from any LMS VC series injection controller

System Include:
• Touch Screen Dash Display Module
• Engine bay mountable Control Unit
• 3 foot Control Unit Harness
• RS-232 Re-flash cable
• Posi-Tap connector to quickly and securely get IDC without any wire cutting
• Color User Manual

Engineering to keep you “On Track”

No after market perforce product claims are valid unless they are supported by dyno test data. So here you go…

The test vehicle was Mitsubishi EVO8 MR running stock turbo, and a VC-25 controlled alcohol injection system. The nozzle installed was a 625ml/min which is way to big for this vehicle.

Run 2 on the dyno chart shows the initial performance with the VC-25 controller and 625 nozzle. The vehicle made 365hp and was very rich from over injection.

Run 8 shows the performance of the VCS3G with out of the box settings to match the VC-25 controller. The VCS3G knows the 625 nozzle is too big for the vehicle and adjusts injection rate to get a nice flat A/F across the pull. Horse power increases to 378 due to more accurate injection control.

Run 10, we adjust the Gain on the VCS3G a little to lean out A/F from alcohol injection. Horse power is now 380 and A/F is still nice and flat, only from a simple adjustment.

End result is a 15hp increase and flat A/F ratio across the pull. Not a monstrous gain in hp, but shows that delivering the right quantity at the right time leads to maximum performance from an alcohol injection system.

Very nice. With coolingmist uping the technology and Aquamist attempting to push a bit more into the US market this is a great altrenative.
Aquamist's claim to fame was the fact that they were the only alky system that maped IDC. I thought Coolingmist the only US WI/A Co. interested in persuing this.
This is great news. And a really good option for someone looking into a WI kit.
The 270 price tag includes the display and controler? Correct?
The pump, plumbing etc is sold seperatly?
Also can or will RPM and alky flow be monitored or maped. (3D maping) I ask because you mentioned the unit is flashable. So I'm guessing upgrades will be avalable.
Also systems that use PWM to activate a valve rather than increase/decrease pump speed, will this controler be able to pwm these valves?
Sorry for all the questions. Just find your product very interesting and a posable addition to one of my vehicals in the future.

Stealth RT,

$269 price tag includes the engine bay control box (the brains of the system) dash touch screen display w/mounting bracket, 3foot controller harness, 7foot display interface harness, and RS-232 cable.

The software is upgradeable so additional features will depend down the road what people ask for. There is a lot more we could do with the system, but at some point you have to halt the engineering and launch the product

If you purchase the IFS-10 (Injection Fail Safe) the VCS3G will show injection flow in real time (ml/min)

Could add software later on that when used with IFS it would be closed loop system and 3D, IDC, Boost and ml/min. The flow would just be used as a correction factor to the system output. yep lost I could do with that.

The system does measure RPM and used in the control algorithm. It is just not displayable since you already have a tach, why use space on the LCD? So IDC would be more useful.

The pump kit will be sold separately for $250 list. Should be on website later today. Add any of our other VC series controllers and you have a Stage II progressive system starting just under $350 !!

There is really nothing wrong with controlling pump speed to vary injection. It can be very accurate when done correctly. If you look at the latest Ford Mustang that is how they are now controlling the Fuel Pump, PWM control. Others have been hyping up the control of a valve, but you really want a type of fuel injector at that point. Similar to the 80s GM TPI setup.

Best regards,

Dan

wow, looks real impressive. I'm on the prowl for a water/meth/alcohol injection kit and your price looks pretty competative to other sytems. I like how it auto adjusts, i don't have the tools (metal or brains) or time to invest in making adjustments. Thumbs up to what looks like another great product, I'll prolly be ordering AFTER the holidays...

Great looking piece Dan. Good job!

I don't understand this part. I thought this new injection controller eliminates the VC-25 type controllers and all you need to add is the pump, lines, solenoids, check valves, etc...?

We are still manufacturing the VC-25 and other controllers. They work good and allow for a cost effective system.

You will find three types of injection systems on the market

Stage I - single on/off type control. Uses a Hobbs boost activated switch. At a fixed boost pressure it turns on full spray. We don't sell these. Good for vehicles that make under 7psi of boost. Lightweight used to sell these on this forum.

Stage II - Progressive control system where injection qty is adjusted based on engine load. Our VC series controllers fall into this category. Prevents over injection at low boost levels that could cause combustion quench with Stage I system.

Stage III - 2D Progressive control based on two or more engine parameters. This is what the VCS3G is designed for. More accurate control, more features and system diagnostics.

Dan

hi dan,

can you give me more informations about the VCS3G please ?
is there any 0-5V input or something like that ? ( for tuning with EGT )
how to tune with the VCS3G ? is it just by a set of the gain on the touch screen ?

thank's
fred

[dlabonte]

Hello Fred,

The VCS3G has a 5 volt line, but it is for a fluid level switch. The other extra output is 12volts 3amps to drive a solenoid, the IFS-10 or NOS relay. No input for A/F at this time.

The controller reads the Injector fuel pulse and Boost to calculate the amount to injection. Setup is very simple:

You enter your estimated HP, the Nozzle you have installed and boost pressure you want it to start injection at. You enter an intial Gain to calibrate it based on your Max IDC. It can log your Max IDC if unknown.

That is about it, ready to go. Any fine tuning you want to do can be done on the fly with the Gain +-.

If you connect the Injection Fail Safe to the VCS3G you can display injection flow rate in real time.

Let me know if this help or if you have more questions. Or send me an email to dan@labontemotorsports.com and I can send you a PDF file of the User Guide. That should also help answer your questions.

Best regards,

Dan

Hi dan,

i received the VCS3G, dual nozzle kit, injection fail safe ....




some questions :

what is the use of the USB-RS232 cable sold with the vcs3G kit ?
i found no information in the vcs3g manual except it is said it is a Re-Programming Cable !
so is it needed to buy an extra software for re-programming the vcs3g ?
is it a free software for vcs3g buyers as me ?

an other question :

in the setup, for a fixed nozzle ( M8 for example ) and boost ( 21-25PSI ); what is the influence of the Horse power parameter for the vcs3g ?
for example :
M8 single nozzle and a set to 200 HP flywheel
M8 single nozzle and a set to 400 HP flywheel ( normal case )
M8 single nozzle and a set to 600 HP flywheel
what will be the flow ? how it works ?


so, i'm happy for all the parts a reiveived from "FullOutPwr" of evolutionm.net
it is a complete kit "labonte performance" never used !
i have the vcs3g, the fail save injection, the tank, the pump, the dual nozzle kit, hoses and all small parts i need !
the quality of the products are really good !

i'm installing the kit in the 3S ! with a 10Liters tank !
i will run with a dual M5 kit just after my "pace products" side mount intercoolers ( smics )
a 50/50 water injection mix seems a good deal !

in any case, i like the labonte performance parts !

@+
