I was looking for something like that in order to estimate the impact of mods on the car (just a rough estimation), so thanks for that, I think it's useful.I'll put a detailed write up on how to do this here tomorrow night, It's bed time now.
Does this mean that if you have upgrade exchaust with less backpressure, the motor is making more torque than what's show on the model?And the ECU torque model starts losing accuracy as you start changing hardware on the engine. Reducing backpressure (change in pumping loss) or changing pulleys (change in friction/parasitic loss) for example will add an element of error.
Who doesn't? :shrug::hitcomputer:Because I like spread sheets and graphs and numbers:lol:
If you have an exhaust and no tune, you are probably making less torque.Does this mean that if you have upgrade exchaust with less backpressure, the motor is making more torque than what's show on the model?
Not sure why upgraded exhaust will cause less torque without a tune, but my thought is that since the model assumes loss from stock components, the actual torque should be higher than the torque estimate with upgraded components.If you have an exhaust and no tune, you are probably making less torque.
The stock tune does not assume a "loss" it uses torque targets based on a standard engine. Deviations will not change that target. Also, it's a relative fact that CAI and exhaust modifications on a stock tune do not add any power, they just make noise.Not sure why upgraded exhaust will cause less torque without a tune, but my thought is that since the model assumes loss from stock components, the actual torque should be higher than the torque estimate with upgraded components.
For example, if a stock component is known to cause loss of 15 ft/lb of torque and its replacement only causes loss of 5 ft/lb, should 10 ft/lb be added to the estimate? Or not because that 10 ft/lb gain would show up somewhere else in the estimate.
I think that we are talking about completely different topics here. I'm trying to find out if the actual torque numbers with modified parts will be lower or higher than estimates shown on the AP.The stock tune does not assume a "loss" it uses torque targets based on a standard engine.

Ok, I see where you are going.I think that we are talking about completely different topics here. I'm trying to find out if the actual torque numbers with modified parts will be lower or higher than estimates shown on the AP.
