Lately evertime i start my car (car has never been driven, runnig hondata s100 with basemap) it dumps excessive black smoke @ idle and if i touch the gas slightly, It also has trouble holding an idle and will die out if i dont' give it some gas, Im very confused, the first time i started the car up after the install with hondata it started perfect, no smoke, held a nice idle, etc...it has went downhill everytime from there. BTW i have replaced the plugs a few times.

 

Sounds like its running too rich. Perhaps the basmap is wrong?

 

im not sure, thats what i thought too, but when i first installed the hondata the car started and idled fine, no smoke, what so ever

 

 

Im wondering if not having the o2 sensor hooked up could cause this? the car is def running extremely rich, Its just really confusing since it ran fine before the first few times i started and now without changing a thing it runs like ****.

 

What was the ambient temperature when you started the car the first few times compared to the temperature now? Do you have a fpr? Its a possibility your fuel pressure got turned up. The hondata base maps are quite good for the idle, its very possible that it needs some tweaking to get it right. If its black smoke, then its fuel.

it was very hot and humid the week i first got it running (not sure exact temps) now its been rainy and colder..I just have a stock FPR, It was perfect @ idle the first 4-5 times i started the car up and has worsened ever since.

Yea im hoping that makes a little difference, but i didn' t have it in before and it still ran fine at first..

 

Bump for the nite crew

 

Black Smoke = Rich burning condition
Blue Smoke = Oil burning condition
Dissapearing White smoke = Water vapor and perhaps coolant burning also.
