Hondata

i have a 2008 civic si with 12000 miles on it
ct-engineering stage 2 supercharger with the 520cc inj. and 3.15 pulley
flashpro sn 10579
i am running the base calibration

today after coming back from a short drive out into town i decided to pop the hood while the motor was running to look around to make sure all was well.

as im looking around my motor bogs like its about to stall.

so i go and hit the datalog button immediatly on my flashpro
i get out and walk to the front of the car and it does it again...
so i go and look and see what my gauges are doing... they are dropping to rich and back to stoich. it keeds doing this until i stop the car.

i checked all the vac hoses there are zero leaks. restart the car and it doesnt do it again.

i have the datalog but my pc crashed and im using my mac.
i will try and get them up soon.

anyone heard of this before or know what it is

Having the same problem. i'll take a datalog tomorrow and upload it. Everytime the fan tries to kick on, the idle begins to bounce.

Post your calibration and datalogs showing the problem as well as a complete list of everything done to the car.

07 Honda civic Si
CT-E Supercharger kit, 3.6 inch pulley, RC 650 CC injectors with clips, Vibrant Header w/ High-flow Cat, CT-E intake (approx 20k miles on SC)
Flashpro Serial Number: FP-SI-US-10164

Below is the current state of my tune. This is still in process. The idle data log was all I could get in the short time I had.

That datalog does not show any problem.

i cant post my datalog because my pc crashed. all i have is my mac now.

Did the best I could. Where the afr dips go 15+ the dan is trying to turn on and it just bogs over and over.
