On a 650 mile highway trip last weekend from SF to Santa Barbara and back, I saw 23.5 MPG. Key differences between this trip and others are the Pilot Sport Cup 2 and the Revo 1+. In the past I’d see closer to 25.5 MPG. When I was stock I was closer to 27.5 MPG, and 30 was theoretically possible on long highway stretches at 80 MPH if you didn’t rip the throttle on onramps.
Try methanol injection!
Kicking myself for clicking on this thread.
…
Stock = 27
Revo 1 = 25
Revo 1+ = 23
Are you going to be making that trip again anytime soon. If you can switch on your revo box try putting it to stock on the way down and 1+ on the way back. Set the cruse control and see if that can be repeated
We k ow that revo runs a bit rich and uses fuel for safety so that makes some sense.

It runs AFR of 11.x the entire power band - flat as anything.
I guess you’re helping me make my point, but you don’t know it?
Also if certain conditions kick in that require further enrichment, it will. You’re not going to see that in a normal dyno run or ‘all is well’ log.
Strange they’d touch the low/cruising load tuning.
I was agreeing and offering supporting evidence. Here’s a screen grab of my car when it was Revo stage 1. AFR is on the bottom.

as I said that’s a dyno run at WOT under hopefully ideal conditions. As we know they’ve been shown to use boost bypass and running fuel rich to keep the car ‘safe’…or their definition of safe. Really it’s timing protection…as in methods to protect and maintain the ignition timing request, and to stop the car from ever pulling timing. It’s weird. I would love to hear someone explain why they did this.
Just look at how smooth that torque curve is. I don’t care how they are doing it. I like my super linear engine.
The tq curve does look smooth I dont have a reference for other dyno sheets but I think it’s important to know most dynos use something called a buffering factor and a smoothing factor. This smooths out the peaks and gives averages in order to make the numbers look more smooth.
I can see the fuel mileage getting effected by having the car constantly going into protection mode if you were at highway speeds.
Yes that’s a smoothing factor of 10. That’s in the software the dyno uses not the tune. Not saying the tune isn’t good but that’s a smoothing factor to make it look that way.
