Hey guys I am new to the forum here. I finished my f20b swap and found that my speedo is now 15% off at all speeds. I used my stock D series vss in the t2t4 trans instead of using the vss that came with the swap. Anyone know if I need to put the original back into the car or should the civic vss work fine and I might have another issue instead? Thanks.

 

122 views and no one has done an h or f swap??

 

it could have nothing to do with that also.. every speedometer is off from the actual speed ure going.. my accord was 8 mph faster then what i was actually going.. it could be caused by a different wheel size, tire size as well. also suspension has to do with it
