I have a b18c1 turbo tuned with Hondata Stage4b. Was running like a champ a week ago. When I tried to start her up yesterday it idled really low around 150-250, and now it just dies after start up. Any ideas?

 

its a good chance your hondata actually went bad...i know because some of the same things happened with mine...when i first had hondata my rev limited was set at 3800, so it wouldnt let me go anywhere, if i were you i would try and contact either hondata directly or contact the company in which you purchaced it through...or try and give it to the company that did your tuning...
