Someone look @ this UTEC log?
My car has been running fine. Slowly in the hotter weather it was really stuttering until UTEC kicked in...thought it might the lower density of the air.
However I haven't been driving it and now it's cold out and is HORRIBLE! Seems to run normal til the UTEC kicks in about 2800rpm. Then it bucks, kick and all round sucks! If I push it a bit it will gain boost, altough I hear the turbo spooling more than what I see my boost gauge read. Cleaned the MAF (yes with MAF cleaner) Checked for broken pipes/ loose pipe clamps. I have never data logged before, but I see that load doesn't seem to go over 30. Timing seems really advanced for the manner I'm driving it. Anyone want to take a look? Keep in mind I would start logging, pause then do it again. Thanks, Sean http://home.comcast.net/~hr2burn/prob1.TXT Am I seeing Throttle postion @ zero?

Check your temp compensation page, if all the Values are 0 then that is probably your problem.

Do you have a wideband? That would be very helpful to include in the logs. Also, log 1 is the best for logging because it gives you the most info. Lastly, it looks like most of your logs are showing closed loop. Meaning the ecu is driving the car not UTEC... Try to log with your TPS and Load values from 25 and above. I assume your threshold cutoff is 2000rpm and 25%TPS? Your open loop timing curves look smooth though. No knock. AFR would be good to know.

Yeah +1 on the AFR, sadly I do not have one. I know with my injectors and while the stock ECU if still running the show I am like 8:1. I feels like it is running seriously rich. I am having a real hard time giving it more throttle or getting up to a higher load...it about threw my wife out of the car while she was holding the lap top. I guess I will have to find a way to get it to the tuner....
I will try another log using logger #6 if this does give more info. What I did on my first attempt is a bit messy. THANKS ALL!

Use logger 1 for the most complete logs. Also post your map so we can take a look at your fuel and timing. What size injector are you using? Were did you get the Map? Was this tuned by a pro shop or you just got utec and installed it and fired it up? To many things has to be set. Are you using a Map Sensor?
I strongly suggest to bring this to a pro shop since you are not really proficient with utec yet. What is your Min/Max Map value? I see you are hitting load 40 at 0 psi. what is your target max boost anyways? I think your parameters are not set right. |

You should tune if you don't have a wideband... Use logger 1 and post here, I'm thinking utec is kicking early and your A/F all over the place. |

Will do tonight AthenG...thanks again. For what it's worth, I DO NOT screw with the UTEC/tuning. I have been to the tuner everytime I do a mod. I am confused how something within the tune could change. That is what it seems like though...

This is tuned by a pro? WTF!! You are hitting load 30 at vacuum... Let the ECU control it at vacuum and Utec take control at above 0 or 1psi. No point of letting Utec take control below that since utec RESOLUTION is ver limited. Yes you only need one map but your Min/Max Map value isn't set right. If you max boost is 10 psi then I'll set the Max Map value to at least 11 or 12 psi just to give you 1-2 psi incase you overboost and make sure your have the overboost cutoff set to what ever is your max map value. |

my injectors are @ 97% duty cycle...If I see much more boost I'm toast. The utec is kicking in sooner beause of how rich I run when the ECU is thinking it's dealing with 280cc injectors. So you think the is something really wrong with this log...or just different? Again I will post a proper one tonight.

Like I said, resolution is very limited in Utec so you dont want to use some of it when you are still in Vacuum were the ECU is well capable of handling it. Heck, some people here don't even let Utec take control until past 3psi. Last edited by athenG; 08-26-2008 at 12:53 PM. |

Wow, that is all very interesting, so could the 0 column help with the richness I am dealing with prior to when the UTEC takes over?

Yes, you tune the 0 column in your fuel map to scale your bigger injector. |

when logging try to log in 4th gear, cruise around 2500rpm and then floor that sucker all the way to redline. Like I said, you are only boosting around 9psi and your min/max map value is set so far apart (around 2psi). This is because your tuner used some of your load column to tune for Vacuum.
