hey guys i posted a few days ago about the boost cut not engaging where it should, i have it set at 15lbs of boost and i had a spike up to 16.5 and leveled off at 15.5 and nothing happened boost cut wise. then i got in the car 3 hrs later that night, and boost cut worked every damn time, wtf?! Now yesterday i went to starbucks, came home, 15 min later hopped in the car to go to work, started it up, and it was running so damn rough, sounded like it was about to stall out, and then i had to put my foot on the gas to keep it goin and it sounded like it was misfiring and ****, then the CEL and red LED shift light came on solid saying that the car was in limp mode...wtf?! the red LED on the s200b box was staying solid tho, so i shut the car off, started it back up within 2 seconds and ran like a champ....wtf? and the red LED on the s200b box is still staying fully lit, not flashing any codes or anything. im thinking this might be my map sensor gone bad or a bad connection b/c first off it wasnt reading the boost correctly sometimes, 2nd it was running rough as hell on a startup then two seconds later when i started it up again it ran fine....any advice? could this be the map sensor or do you think its something else? thanks.

 

I don't know, but mine does the exact same thing. I mean _EXACTLY_ the same thing. I just thought it was the Hondata doing that.

 

Sounds like a bad sensor and you need to have your hondata tuned. If you are trying to tune it look at the 2d and 3d maps they should be linear and not touching each other.

 

bad MAP sensor? and tuning...the car was just tuned last month. should i just reflash the EPROM with the same tune? if the tune was bad to start off with wouldnt this have been happening for a while? thanks

To check your cel' just connect with hondalogger and go under ecu error codes it will display your cel problems in their. Do that first and post a screen shot of your maps in the 2d and 3d if at all possible. It kinda sounds like your o2 is being screwy. I say check your cel first then go from their
