I had, but taken out by my mechanic later on. Some told me it's a surplus item for normal cars due to the engine vibration isn't that serious (unless you had a over 300bhp+ engine that rocks ur car hard)
Saw some advert abt it. Looks good and preloaded for ER34 specs. Has built it Speed limit defencer and Rev limit defencer. It says that the item can be plug in to different car depending on the wiring harness. Cost...
this always happen when i leave the car in the hot day (lunch time). the needle just sticks to 0. after driving about 5 minutes, then it just working fine.. is this normal? using apexi EL..
