I have a stock b20 vtec.

The problem only seems to occur when it warms completely up. I give it gas it sounds like its getting alot of more air then the fuel kicks in and it revs so it kinda whistles then revs. but when i let off the throttle the rpms fall and dont catch and the motor dies.

I have a oil catch can setup one hose to the back of the block one hose connected to pcv and bottom drain hole block with vent on top.

Has chipped ecu with b20v basemap.

Already tried b20vtec.com but chrome isnt liking that website

 

come on guys don't be shy.

 

Maybe the base map is not for your B20

 

Oh the irony of using the word stock when talking about B20Vtec... I am going to say that your tune is no bueno at idle.

Read Idle problems and oscillation section: http://www.hondata.com/techidle.html

 

Is this the only answer im gonna get from honda tech is the tune? Alright ill take your word for it. Im gonna take it down here to mainstream performance and let them dyno it.

ps You so called techs? SUCK!

 

So if it is the tune, do we still suck?

 

Why don't you just try a stock ECU first if you have access to one. And always when you make a thread list as much info as possible, ie year, make, model, mods, ECU, recent or any known maintenance done, CEL on with codes, etc. just saying your b20v dies at idle doesn't help without that extra info to go on.

 

I have a buddy you was going thru this same exact problem just the other day. It has since been resolved with my help. Too bad you're not gonna hear my awnser, since I suck and all

 

I tried my p2t Ecu and it still wanted to choke rev up then die when I pressed the gas. Sorry about the post earlier guys I was just very frustrated with my phone and I took it out on you guys.
