Here is the other part of the same log...looks like the front O2 goes to zero for a sec.

 

my email is in my sig

 

I tested the car cold...when its clod it wont buck...I tried it 3 times....no problems...and soon as it got warm it came back.

I also looked at the Boost Desired table...whats with the dip here? This is off my stock map. I have a MBC is this even relevent?

 

What about the boost limit table?

You're correct. BDEL is irrelevant with an MBC.

 

 

Does your car do it everytime?

 

Everytime, unless the motor is cold in the morning.

 

Bump

 

whats your load value set at?

 

Sorry, I fixed it. I had the lean spool messed up. My ECU did like when I set the start/stop to 2500. Aaron fixed it for me by turning of lean spool in the XML area. The car is fine now....other than that fact I have to retune the whole car.

 

Well it wasnt just what it was set at, it was also the ROM def that was changed. We got it though thats all that matters.

 

^ My ninja!

Get back to me about the injectors!

 

I had this problem once, (after a few tests) it was related to the open loop transition at that RPM. I just lowered the load at that RPM cell and it transitioned from closed to open without the hiccup.

...i also stopped logging from <2500rpm


edit: i also had a similar problem when messing with the boost-enhancement/lean spool tables.
