So tonight I was looking at my map from November 22, 2006. I havent really driven the car since then so I was looking things over. I found that I had vtec in a higher spot than I wanted so i moved it down, saved it in crome and attempted to burn a chip like i have 1000's of times now. Go to start the car and it acting like it is running SUPER rich. Hit the gas and it hesitates. At idle it wants to kill itself. Now I know its not that map becuase I ran it for a long time. I have also compared it to other people's map and the values are similar. If you want to take a look at it be my guest and ill send it to you.

Anyone have any ideas?

Cliffs notes: Car starts but runs like its really rich. Hit the gas and it stumbles. Same map as before only thing I changed was the vtec engagment points.

Things I have done so far:

Burned chips multiple times
Used 4 different chips to rule out a defective chip
Reinstalled crome and burn1
I have done nothing mechanically to the car over the winter (in fact I drove the car just last week and ran like a champ)

 

i am having a similar problem.

but when i hooked my ecu up to datalog everything was getting fucked up signals. it thinks its in boost at idle, iat is like -80.

but anyways i am not trying to thread jack i am just wondering if you have tested any sensors or dataloged to see if any are ******* up.

your map sensor is wire incorrectly or map sensor is fucked...

What does your afr read?

Also double check to see if your map sensor is working correctly as well...when the car hesitates when u flip the throttle...you need to adjust your tip-in fuel..

 

sounds like the chip may not have burned as expected. Reburn 'old' file and start car, then reburn 'new' file and start car.

 

well the I saved over the old file (since I only changed the vtec point). I thought it was the chip to, but after I burn the chip. I take it out, put it back in read chip save file. Open it and all the data is correct.

AFR goes all over the place.

bump for you cause i think your solution is gonna be mine so lets find it out!
