Hey there was wondering if anyone could help me as to why my b18c blows out white smoke on cross over to vtec.
Has a new spoon ecu but isn't tuned, a few of my mates have said that'll be the cause for the smoke but want a few more opinions as to what it could be.
Cheers

But usually with especially around this time of year in cold countries it could just be condensation sitting in the exhaust , my winter start ups are very smokey.

It's more so only when crossover, it does smoke normally on cold start but when it smokes on crossover you can smell the fuel but the smoke isn't black it's like a grey/white

I'd say it's oil, don't expect it to be sky blue smoke lol. Do this - find a long steep hill, put the car in third, accelerate and then lift off and let it roll down the hill still in third, off throttle. Once at the bottom when the revs drop to some 1500 go WOT and check your mirrors or have someone drive behind you to check. If the car emits a cloud of smoke when you stamp on it again it's oil getting in the cylinders, either piston rings or valve stem seals worn, more likely the latter.
