aight got an ls vtec on boost...im running chrome and everytime i boost the car i have to turn the car off then back on or it will die out. WTF is the problem...ive changed my map..ran a 3bar map...and the car also will not go into vtec on the dyno but will in the streets....plz help.

 

Wiring issue more than likely

 

not sure about chrome but i think you have it set wrong put this in the ecu section those guys might have more insight. like your ect is to hi, there are a lot of places to set vtec control. try looking at them

 

Did you scale the ecu for the new ap sensor?

 

we set the map for the 3bar....and vtec control is set properly...also when u downshift from 5th to 3rd the car die when ur pressing the gas??????WTF

 

bad rom burn, bad tune, bad ecu... tuner is an idiot? wiring issue, etc.

way too many variables. we need way more info to even begin to help

 

This may be a really obvious question, but the obvious answer isn't there.

Wideband readings?
