Just to let you guys know from my experience of ECU tuning and for those who plan to do the same. My car is an E46 323 CI but is lack of power especially during acceleration. From an advice of a friend (Sashi ,that you) I did a HIOP ECU tuning for a cost of RM 2000 and wow.....I can certainly feel the different. I only have to wait for a couple of days to get my ECU tuned as Calvin needs to copy the existing ECU software and email it to HIOP in German for tuning, but it worth the wait. The car felt so much 'lighter' and the acceleration is much more stronger. It wont beat an M3 that's for sure but it sure makes the car more fun to drive. For any 323 or any BMW owner who wants to do an ECU tuning, HIOP ECU tuning is the way to go.This is not a promo, but only a testimonial from a happy BMW driver. For those who want to contact Calvin he is available at 019-XXXXXXX or his website at www.eurocarmotorsport.com.Best Regards323Ci
