That is not the only one that reads incorrectly. oxygen sensor reading is off also. My OBDII logger reads .94v but Evoscan reading is below .92v. I hope next version will fix these isusses.

 

Well, just to confirm for those who didn't bother to do the computation.

0.6v is 12% of 5v.

Mine reads between 12 and 13%.

And to think I guestimated that.. LOL

Anyway it at least puts the question of it being an issue to rest.. In reality the value probably should be displayed as a voltage in EvoScan, but very few would understand what it means if it was..

 

My idle reads ~13% on Evoscan and 0% on PocketLogger.

 

To calculate the TPS % on a 0-100% scale, just use the function:

TPS = (x - 12) / 0.88

where x is the number logged by Evo scan.
