Does anyone know why the VSS on my Kpro (JDM ITR 04') and the actual speed my speedo reads are miles out?
For example flat out in 3rd and my VSS is reading 55mph which is way off of what I'm actualling travelling.
I have the gear ratios setup correctly on Kmanager so it ain't that.
Any ideas?
The speed as calculated in the ECU is dependent of the speed sensor signal and nothing else. What the exact difference in speed between the gauges and datalogging?
I'll do a run today and take a note specifically what the speedo is saying.
Kpro also never displays the correct gear I am in. Could this have something to do with it?It always shows 2nd when I'm in 3rd or 4th. It always reads gears lower than what I am in.
Just had a brain wave. I live in UK and got a JDM import where I believe a speed delimiter woulda been fitted.
Could this be working in a way that fools the ECU the car is actually going slower than it is to allow the car to go faster than the limiter is set at?
If so can Kpro get round this problem? By correcting the value if it is out a certain percentage?

Really? Feck that hassle. I can live without it. Cheers for that mate. By the way looking at your username, I'm just wondering if u r Scottish? As I am.
I'm guessing most cars in Uk running Kpro will be having the same problem too tho huh? I might take a look at it but dunno what was fitted as bought the car already passed SVA etc.
I'm from Fife mate. Where you based?
