I am thinking correct. Hobbes, your correct if you are thinking about a naturally aspirated sled, not a turboed sled. WRONG, THE SAME BAROMETRIC CHANGES EFFECT BOTH N/A AND FORCED AIR MOTORSWith a turbo, you aren't compressing blocks of air with less molecules in them. You are compressing the molecules themselves until you achieve the desired pressure set by your wastegate. INTERESTING USE OF WORDS, UNTIL YOU ACHIEVE? HOW IS IT EXACTLY YOU ACHIEVE YOUR DESIRED BOOST LEVEL? (THESE ARE RHETORICAL QUESTIONS, I KNOW THE ANSWER)
I have a manual wastegate on my sled.WRONG, ALL WASTEGATES ARE PRESET BY THEIR SPRING RATE. YOU HAVE A MANUAL BOOST CONTROL KNOB THAT WILL ALLOW YOU TO INCREASE THE PRESET SPRING PRESSURE BY ALLOWING THE AIR PRESSURE THAT WOULD NORMALLY FORCE YOUR WASTEGATE SPRING OPEN TO BLEED OFF INSTEAD Once enough molecules are compressed to overcome the spring in the wastegate, you have compressed enough molecules to achieve the boost pressure and exact amount of oxygen molecules need to make the power you want. AGAIN, TO MAKE THE "POWER YOU WANT", SOMETHING IS CHANGING RIGHT? AND YOU ARE MANUALLY CHANGING IT.
The vipec ECU gives me all the information I need to produce the power I want.CURIOUS, WHAT INFORMATION IS THAT EXACTLY? The data log option in the vipec allows me to look at what my motor is doing at any given second so I can understand what I need to do to achieve the desired power and adjust accordingly. There is no automatic adjustments.WITH THE VIPEC, THERE ARE HUNDREDS OF AUTOMATIC ADJUSTMENTS GOING ON EVERY SECOND But once I had the settings where I wanted them, I haven't touched them again and my readings are consistant day in and day out.MORE LIKELY, YOU ARE CHANGING YOUR BOOST BY TWISTING YOUR BOOST CONTROLLER KNOB, AND THE VIPEC IS FUELING YOUR MOTOR ACCORDINGLY BY READING THE CHANGES YOU ARE MAKING... AUTOMATICALLY
With piggyback controllers or reflashed ECU, you have no way to know what power you are making.UM, THE ONLY WAY TO KNOW WHAT POWER YOU ARE MAKING IS BY USING A DYNO Its just seat of the pants feel and if it isn't running right, you have no way to know what to do to make it run right. Its more of shot in the dark.THE VIPEC IS A GREAT FUEL CONTROLLER, BUT IT IS JUST A FUEL CONTROLLER, NOT A POWER CONTROLLER. IF YOUR FUEL CONTROLLER; NO MATTER IF YOU'RE USING A VIPEC, DOBECK, STOCK ECU OR ANY COMBINATION OF THEM; GIVES YOUR MOTOR THE CORRECT AMOUNT OF FUEL AT ANY GIVEN TIME... IT'S GOING TO MAKE THE SAME POWER REGARDLESS OF WHAT THE LABEL ON THE BOX SAYS.
