this happens only when i pump ron95. Ron97 no problem. When i reach 40km/h with second gear, i let go the throttle pedal and immediately press to accelerate, i can hear a short "kreeeek" sound. I when proton check, they advise me to use ron97, they told me that there are already a few cars have this problem, but they dont know what is wrong. So i send to my mechanic, he said it is engine knocking.

QUOTE(turbocharged @ Feb 8 2012, 12:26 PM) mostly while i accelerate at 2.5k RPM. The most obvious is 2nd gear at 40km/h, as what i described, you let go the throttle pedal and immediately press to accelerate.QUOTE(miuk @ Feb 8 2012, 12:26 PM) Have you remaped and what version if you have? Please send the info the K3. It has nothing to do with K3 mapping, i got this even before the mapping as what i remember.So far i use ron95 and dont have this issue even i'm running very aggressive mapping. Different car will have different character so might need to re-tune (i'm assuming you have remapped your car). Best just come TT and the let macgyver test drive. |

QUOTE(K3nnYkl82 @ Feb 8 2012, 12:30 PM) 4B10 will have higher possible kena.. as we have 10.5:1 compression rate.. Can bro, but i have just pumped full tank of ron97, may takes about 1-2 weeks to finish, then i put back ron95 to get the knocking back. Really appreciate your help, proton told me "is like that one, last time wira also got." WTF.Adrian's car.. even before remap .. kena knocking d .. i just check on the map .. yes.. from 2250rpm to 2500 .. the ignition timing is suddenly much more aggressive.. i think that causes the knock (some cars) .. see which day u free.. come over my place (must be i free also la) .. then i retune that part we go have a ride.. until the knocking sound not there anymore... then we name it version 1.5 ... QUOTE(stewPik @ Feb 8 2012, 12:31 PM) yea, i also have, but only during jam when clutch and declutched a lot, actually i'm suspecting is because our car is too damn heavy and when you running on low speed not enuff torque to compensate hence the knocking, well at least thats what i think, usually if cruising and high speed not an issue... This is exactly what i have, only at low speed. Above 80km/h hardly got the knocking. |

QUOTE(K3nnYkl82 @ Feb 8 2012, 12:37 PM) lee.. just double check original mapping ... the stock one.. from 2250 to 2500 rpm .. the ingition went much aggressive also .. that could explain the possible knock .. the AFR (during Dyno .. ) is the over 13 at that range... Bro, i got this problem before your mapping, so i dont think it is caused by your mapping. When the knocking is back with Ron95 later, i will let you know. Manyak terima kasih.i think i retart the timing there a bit shd solve the issue.. Guys.. these are the useful information i need u guys to feedback .. so we have MORE version .. COPYCAT style : drive a while more .. no problem ge la |

QUOTE(K3nnYkl82 @ Feb 8 2012, 12:45 PM) Lee... i see, thats good, happy to know there is solution. I am not reeeachhh enough to pump ron 97 every time. "increasing mixture turbulence or swirl by increasing engine revolutions or by increasing "squish" turbulence from the combustion chamber design" This oso explain why after remap .. lesser knocking.. coz i tuned up the mivec's setting d |
