If you dont know the FWHP and your customer expects a 15% loss then doesnt it make sense to take the RW number and assume its 85% of the FW number?
In which case math suggests you take the RW number and divide by 0.85 to get the FW number. Now that may be lower or higher than the manufacturers claimed HP which just means its a strong/weak motor OR the driveline loss isnt 15%, but as you stated its drilled into peoples heads that it should be 15%. So they walk away thinking they got a strong/weak motor from the factory or their mods are putting down more/less than the advertised/expected gains. Doesnt really matter which since the 15% stays standard all the time for them and their car. They just never know the exact HP number but it should be within 2-3% plus/minus the calculated number. They should be concerned only with the delta anyways. Not trying to be a jerk, just seems logical to me. Why fudge math? |

You would think, but then you get slammed because your dyno is a glory machine and spits out higher numbers than advertised by the manufacturer. It's a damned if you do, damned if you don't kind of thing. |

this is always the way I have done it as well... but it's easier to just simply talk in terms of WHEEL HP, and leave others to do their own math and generate their own figures... because indeed... there is no reference for the flywheel numbers (we already know that the 1M is under-rated from the factory) or powertrain loss readily available.. (the 15% figure is a rather arbitrary number that works "close enough" but could differ from one make of vehicle to another..) |

Drivetrain loss can't be calculated by a percentage.
It takes a specific amount of energy to power any given drivetrain depending on all of its components. Different wheels and tires, a lighter driveshaft or even something as simple as changing to a different gear oil can affect what the exact number is. I don't know what the amount is for a 1M but lets say it takes 40HP to power its drivetrain. If nothing on the drivetrain is modified other than adding more power to the engine it will continue to use 40HP of whatever the engine's output may be. If you start off with 340HP and add 60HP, that's a 17.6% increase in power. If you go by the percentage based drivetrain loss then it would now take 47HP to power the drivetrain, which is absurd if you really think about it. There is no extra weight for the engine to move, no additional force that requires it to all of a sudden use more energy than it was doing before it gained this new found power. That would be like saying that picking up an object with my hand after putting on 17% muscle mass would require more energy than before I gain the added strength. OP, good gains and great looking ride. |

This is another reason why I don't like to mess with figuring flywheel numbers unless I have a base run from the same vehicle in bone stock trim. |

Stay tuned for the ESS Tuning Stage 2 tune for the 1M.

Hi biglare,
Congratulations on your new 1M. I thought that you were getting an AW 1M, that's what you told me when we met in mfest? Impressive numbers for stage I tune on 91 oct fuel. Do you know if the stage II tune will require 93 oct fuel or not? Enjoy your little rocket Regards Khalid

I am not sure what the IAT's are, but contact ESS and I'm sure they will be happy to explain for you. Yes, the car feels better than what the dyno shows. Am I not allowed to state my opinion and post up an actual dyno's? The car drives perfectly on the street, but pulls like a freight train on the hills by my house! The throttle response is immediate and the every day drive-ability has been retained with the ESS Stage 1 tune, except you just want to hammer the car everywhere. Ha! Also, I just got back from a track day in Orange County with the 1M and the ESS Stage 1 tune. I had the car out on the track for six sessions of 20-25 minutes each and the car performed flawlessy! The oil temps barely got above 250 on a 85 degree day. Throttle response was perfect and immediate! I will be posting a separate thread on the track day soon. Oh and when you get your 1M you can get whatever tune or piggyback that you want as it is your prerogative.

Delta is the difference. The biggest gain between the base run and the current run. In the real world it shows how much more power the mod(s) have added to the baseline power.

This thread is about my ESS Tuning Stage 1 tune and the dyno numbers that I put down with it compared to stock. These are the facts and its up to everyone to draw their own conclusions. I love this tune so far and have even tried it on the track without any issues at all. The 1M performed flawlessly and I'll do another post specific to the track event very soon. Yes, the track is in Irvine at El Toro airpark, OCRC. Here is a link to the video -->

I take it that the course is semi-permanent..? WOW that's a lot of cones... and I say that as a person that's set up a fair share of autocross courses over the last 15 years. That looks like a time trial basically.. nice driving btw. |

Have you (or anyone) tried the ESS stage 2 yet? What does it require? Downpipe and FMIC??

Would love to see Dyno Graphs with this tune and Akrapovic Exhaust and DP's

Sooo.. they've been "developing" the tune for over three months now. It sounds like they're not actively developing it, but plan on.
