JWT ECU Not happy with Blow Thru ( IDLE / CODE 34 )
Hey guys,
Been running a JK Tuning ECU for a while with my N62 Blow Thru setup, Zero codes or Stalling but was considered a ( get you to a dyno tune ).
Needless to say ran into an issue with a MAF & FPR failing over the years and my tune no longer was a good fit. Had a JWT ECU laying around
so being I am not sure when I can ever make it to a DYNO I figured I would just get my JWT reflashed for my current setup.
Put in the new ECU and go for a run, Car pulls hard thru all gears and everyhting feels great... UNTIL I have to stop.. Stalls almost every time,
Once it warms up from cold idle, Stalls some more.. Also throws Code 34 and flashes the check engine light which I have read can be ignored.
Any ideas why with the Chipped ECU I had 0 codes and 0 stalling? When talking with JWT they believe its cause of the blow through and suggest
setting up like the factory had it.. Now I can do that but would require redoing all my piping and adding a bunch of extra hoses. Any insight would
be great, Have others experienced the same issues? Bummer just spent money to get re-tuned and now even though the car revs smooth and pulls
hard it loves to stall out..
Didnt think the blow thru / draw thru and BOV to ATMOSPHERE would make much diff since the BOV is after the MAF..
Really dont wannt redo my engine bay its clean simple and did work fine.
If DRAW THRU is the answer than so be it, Just need to have someone fab up some more piping... The tune thru the rev range feels perfect.
