At 3500 rpms just entering boost, my car spudders. The rpms bounce around +-200 rpms, and it looses all power. Now its only at this spot on the car. I can take it to 7k+ no problems. So i check my basemap and everything seems to be on no larger decreases in fuel. My basemap is from Evans so im very confident in it. Anyone have any ideas what to look for?


setup
build b16a 9:1, gt30r, rywire harness s300 hondata, zietronix wb (open loop) New plugs wires and coil.

 

here is a snap shot of datalogging when it happens

 

what ignition are you using? msd? we had a digital 6 do the same thing and it turned out to be a bad capicator in the box. if your using msd bypass it and see if it still does it.

 

No man, its all stock with a new coil. Im thinking of trying a new icm

 

I'm having the same problem, let me know if you find a fix.

 

Same spot in the map? Hondata too?

 

all grounds on the motor

 

Check the grounds? They are tight but i might pull then and sand em down.

 

Seeing a how its a base map, i would think thats your issue. Bring the car to whomever is tuning and get it tuned.

I send people base maps all the time and I tell them that the map is just to get the car started and running, nothing more.

 

I agree with you and I got an appointment at evans june 19th. The only problem is a 6 hour drive, i was just trying to get the car running well to make that drive. I had the entire thing torn apart for 2 years, new harness new turbo setup. I rather try to work out the bugs before breaking down 3 hours from home.

 

So i found out my dissy is a dissyking pos. I just ordered a new ICM and new housing from honda, i got a new coil (just replaced) from honda. im going to try this and see if it was my problem.

 

also check your grounds to your ecu down where the harness plugs in. we had another car that had bad grounds off the ecu. we just had a loose connection in the pinouts
