Yeah the tip-in thing with lean fueling is definitely part of the problem on the stock setup. I somewhat remedied that on my car by going over to the A:F tables and making things a little over-rich in the low RPMs at low throttle. Upside is there's fuel available for that tip-in, downside is I get some occasional backfires when transitioning from engine braking back to neutral throttle at low RPMs and low throttle input (e.g. engine braking gently down to a stoplight and popping into neutral just as it's reaching the point where the engine would naturally start to lug out for being too low. If I don't time it just right, nice little fireball pops down the exhaust).
Are you saying you corrected your lean spots in that same A:F table, or elsewhere? |

Hmm that's pretty interesting. Good to know. I definitely need to get out of this canned tune O_o. We shall see if I still have this car within the next year or so.
Unrelated. I notice there are times I have issues starting the car, and it doesn't matter how hot it is outside. When it starts I smell a bit of fuel as if the engine was flooded.

You're running a canned tune on a forced induction car?
Dude, not to be rude, but that's fcking retarded. The canned tune is to get you to the tuner to have it dyno tuned properly, not to drive around on for months (years?) Holy crap! |

There really has to be a fine balance between not enough fuel to too much fuel. Do you have test pipes?

That's ignorant. No one can make a canned tune that is 100% correct for a car they've never touched and never personally had on the dyno. Much less a freaking twin turbo tune.
Oh well, his car, his problem. seems he's having drivability issues already. |

So it is apparent to me that you have no Friggin clue to what you are talking about.

Ok. Some reading. There's a guy local here whose car barely ran on the canned tune from Sam @ GTM. You got lucky, I'm happy for you! |

I got my car fine tuned from Jon @ Z1 also. Sam's tune was very rich and he leaned it out a bunch. I gained a lot from him leaning it out. Digi I'm sure your tune is fine especially if u ran it this long but like I said earlier theres no need to run that rich. It's prolly like a super extra safe rich can-tune. Plus drivability is prolly compromised a bit. You're good to ride but after spending all that cash on the kit and supporting mods I personally wouldn't skimp out on the tuning part.

Wow you're making nice power. I think 500 whp is my target as well with this new setup, but I care more about quicker and smoother response. Over 23k miles (knock on wood). The car was with Baker Tuning for over 2 months, and I picked it up during Labor Day weekend last year. Sam says he wasn't given the datalogs so he could send the correct tune, so it was still running the canned tune. So I recorded my logs and sent it to him and heard no response from either Sam or Mike. I wonder if it's because of the MBC that they don't want to touch my car. At Baker, they were playing it safe at 6 PSI (no boost controller or wastegate tweaks) and this canned tune not knowing what my driving habits were. Nearest tuner for me is in KC, which is 3 hours away. I wouldn't mind having Z1 tune it after the new upgrades. [sigh]
