Speed Adjust

[WyldCFH]

What's the in tune Speed Adjustment for the EMax? I'm thinking it is 0 but cannot remember and @Claviger CES+Ramair tun has it set at -5. The Avon and Emax can't be that different from one another.

The E-Max will pretty much correct the speedo optimism. Leave it as is.

That explains it. Running Exedra max and yes same tune with -5. Cruising along at 70 mph my rpm's have been running a little higher. Plus it seemed we were going a little faster than normal. Now we know it is not just are imagination.Thanks wyldcfh for posting this info. Get done mounting the new tires going to reset to 0.

Thanks @barbagris

@sonny it is a tradeoff. If you fix the speedo, your odometer will be off so milage going further will be wrong.

Download an app for your phone called SpeedGlow. It will tell your your mph by gps n you’ll know how far off yours is

Rather have the speedometer working correctly

The E-Max corrected my speedo reading, before the max the speedo was reading about 5kph fast but now it’s pretty spot on, I have checked with my GPS.

If you have a GPS you can use it to correct your speedo. You have to figure out which way you need to go however with the TuneECU adjustment.

Tune is -5 but we are running a Exedra max on the rear.

Does one need to run the 12 minute adaption tune when changing the speed adjust? My speedo is off about 3-4 MPH at a -5.1. It came with the Tripp Tune Map, so I left it as it was.
I have a couple of GPS apps and found the difference. I'd like the odometer to be correct, too.
Thanks!!
