So I have a 99 ex, with a 99 si engine! Everything works perfect sounds freaking cherry. its at 1.5k rpm when i start up my car and let it warm up and all but probably lets say after 10-15 mins of driving when i come to a complete stop at a light it would go down so low to the point where m whole dash would shake and it is ****en annoying. I need to fix it i want it to run even more cheery help!!! please!!! every suggestion helps thx!!!

The correct one for the engine. Where did you get this basemapped chip from?

HondaScene

It was already chipped when I bought it. So i wouldn't know but hey im willing to throw some cash out to make my car run well. Anythign i should buy stock p28 ecu?

What? A P28 is not the proper ECU for that engine. Go to Phearable.net and have them burn a proper chip. $35.

What ECU is in it and how do you know it's actually chipped?

Red_Army

get a p30. or run a p30 basemap on the p28.
either way use phearable.net good place.

Good for you and with all due respect but I could care less about VTEC "cracking" since it isn't relative to the low idle issue. What ECU is in the car?

HondaScene

Well just saying, it's a p28 ecu

Then get a P30 basemap from Phearable.
