hi guys just had plenum pull done few days ago,got 555cc nismo injectors and tom pzp chiped the ecu to run the car. today 1st time i drove the car,and lotsssssssssss of white smoke was coming out of the exhaust. left it running for an hour and it stoped the i drove up and down about 50 meeters then smoke was comming out again the parked the car after few minutes it stoped again,any ideas pls car is ideling fine
I knew someone's zed that did the same but he had a dead cyl for a bit due to no spark and all it was, was fuel all through the exhaust. could it be over fuelling? is it burning all cylinders when driving? Sounds like it needs to be tuned. You got the ecu and bigger injectors so its probably dumping alot if fuel. Does it smell strong of fuel?
Chances are you are overfueling. Pull the coil packs one at a time and see if you have dropped a cylinder. Other than that, the tune is a stock one modified for 555's so it wouldn't be overfueling because of that. Do you have any fault codes and are the injectors brand new?
fault codes according to datascan where 02 sensors (1 dead, 1 ok) and detonation sensor, so makes sense that the car would be overfueling.......
Yeah if he's got a 34 then he'll be using the low octane maps.... hence the definite overfueling problem. Combine that with 555's and you may aswell just pour fuel down the plug holes. O2 sensors wouldn't over fuel that much.... It'd run rich but wouldn't cause that much unburnt fuel... P.S. AK, I hope you don't have new cats!
is it definately white smoke? I thought white smoke is water, blue smoke is oil and black smoke is fuel
easy way to tell is to use ur nose , if it smells like fuel and ur eyes are stinging , most probably unburnt fuel.if it smells sweet could be coolant. If u get black smoke it is fuel thats already burnt. Def check to see if it firing on all cyl , do a load test to be sure. Regards Trev
smoke hey mate, no its not fuel smell it just whit smoke,and it seems to run on all 6 cylenders so i think,but ill get it check and make sure that its running on all
Settle... The car might just need to settle. Since you've done a lot of changes in one hit it might just blow the smoke because of that and then after driving her for a while it might settle and clear. If you can't smell fuel, then I'm not so sure it's the tune or injectors. Is it thick white smoke which hangs around or clear thin smoke which disappears quickly? Cheers Rob.
Black or Gray Smoke Smoke may be coming from incomplete fuel combustion Clogged air filter Carburetor, choke, fuel injection or emission system malfunction Ignition timing off Blocked manifold Oil leaking on exhaust system -------------------------------------------------- Blue Smoke Engine oil being burned Oil leaking into combustion chamber Worn piston rings, valves or cylinders ------------------------------------------------ White Smoke Coolant and/or water being vaporized in combustion chamber Engine too cold (no repair needed) Head gasket leaking Cracked block or cylinder head
has the car ever blown the turbos and dumped oil into the intercooler piping? oil can pool in the intercoolers and cause smoke.
smoke its thin white smoke, and i did check the injectors they r all firing and car is running on all 6 for sure, ill be taking it to tom at pzp hopefully he will sort that out for me,i dont think its a big thing.
