Hi,
So we know that when u change your stock wheel to a new one with different size, teh odo and speedo will be inaccurate...
Was running 205/65/15, now running 215/45/17 WHEN 205/50/17 would be closer, but my backside itchy...
Was on 18.5kg with rims and tire, total 74kg.
Now on 16.2kg with rims @7.2 and LS2000 @9kg bringing a total of 64.8kg
A loss of 9.2kg off the unsprung weight. But my FC went up... /cry
So now my speedo is about 10 km off/higher against my GPS (according to formula, its suppose to be 3.4% higher based on the differnce, but its aint so for my case). With this, my odo is affected/screwed and there goes my calculation for my FC...
Anyone know if theres a way/programme to let the ECU learn its new rolling radius?
