So I hit a glitch in my project today....and i'm concerned and i think i know what the problem is, i just don't want to face the music yet...so i'm hoping someone on here can give me a couple ideas as to what else the problem might be. A few of my friends have said they see smoke come out of the back of my car when i hit vtec...since i've had the car running, about nine months now i think. Now i know i'm running rich. I always figured they were talking about the richness, and when i got on it i could smell the richness. The basemap on my chipped p28 was given to me as a "safe" one to get me going. ya know. Anyhow once i got the car running and at least seemed to be running really well, i stopped focusing on the engine and began working on my suspension setup, fixing the interior up a bit (bought a totally stripped shell), etc. I set my vtec to kick in at 6,000, basically to use on the freeway now and then to pass, whatever, i've been keeping my shifts low and i drive my car daily, so my build is very focused on reliability. I've been waiting to really start pushing the engine till i fixed up the other things around the car and had enough money again to start tuning the motor more appropriately. This is where I am now. I'm about to get another tune on the ecu and just ordered a handful of new goodies for the motor. Well on the way home from work yesterday a friend of mine happened to be on the road next to me and i decided to give a little show and topped out third and got pretty far into 4th as i blew by. Later my friend was like why did you have so much smoke coming out? So today i found and empty stretch of road and hit vtec in 2nd a couple times while watching my rear view. A pretty sizable puff of greyish smoke came out the back. Not White white like coolant, i didn't see any blue, and it wasn't real black like i was expecting from running rich. Um shit? not what i wanted to see or expecting. Like i said i haven't noticed this before because i usually don't go fast or shift over 4500, no need or want to yet. I'm not loosing any coolant, i do go through oil a bit, but every honda i've ever had and tuned uses some oil... Tomorrow or the next day i plan on letting someone else drive it *hates handing the keys to anyone else* and so i can have a better look from a following car. Anyways sorry for the long post but most of the time half the damn post is trying to figure out whats going on before problems solving can start. So hopefully this gives a solid start. I found a few articles on here that touched on it but not completely. I fear that its my rings, I don't know why they would be bad or have gone bad though. If it is all well, i guess i'll be taking the bus for a week or so while it's in the shop eh? I'm hoping that maybe its just an ecu problem and that maybe when i take it down to the shop to get a proper tune the problem will resolve itself... Any thoughts?
