    TCC lockup vs ECT/IAT on 3.8L cars?

    This is for a L67 car, 2002 GTP specifically.

    Does anyone know how to change this? My MPG has taken a dump in the colder months - it seems like anything 32 or colder read by the IAT will cause the...
  3. Is there anything I can do to make my car always start like it's cold?

    You know how it just roars to life... Seems like once it gets above 60* outside it is less "energetic" on startup. Is it as simple as the IAC position? Any ideas? I can't be the only one that has...
  4. 80% duty cycle on 60# injectors? Wideband is wrong?

    Trusting my wideband 100% I 'tuned' my MAF table which caused me to skew the MAF table almost 30% at the higher frequencies. I am/was running the stock MAF table for an 85mm maf.

    As a result, I am...

    Possible to disable anti-aliasing?

    My laptop is old and does not like the anti-aliasing. Makes the graphs scroll slow and chew up battery. Anyway to disable this?

    Russ, sorry to confuse lol. Here's the deal. I know another person with an LS6 maf like myself. At idle, his maf shows 2.6k hz. My car shows about 3.1k hz. Same exact MAF sensors! I have my idle set...

    Right, I get that, but why wouldn't two cars, given the exact same setup (but different mafs) flow the same "lb/hr" regardless of the hz they are measuring?
  8. MAF vs transmission pressures, someone please help!

    Why would an 85mm maf sensor and a stock maf sensor not be measuring the same lb/min, in the exact same conditions??

    I have a scan of my car with an 85mm maf sensor measuring 1.2lb/min at 3200hz...

    Do you have a cat? If not, disable warmup spark correction with TinyTuner. My timing goes right to 27* once I start, no matter what temperature. Also, disable cat testing

    I didn't know you could change any PE enable settings other than TPS in HPTuners? Unless you're using a .bin with TinyTuner... Anyway, set it to 32%, that should get you pretty close. You can mess...

    Good fuel trims is a side effect of maf tuning. The real reason you "tune" the MAF is because WOT fueling is arguably completely dependent on it. Anything below like 4k hz will get taken care of with...

    If you take a stock tune and put 100% gasoline into the tank, the car will achieve 14.7:1 using XXX amount of fuel. If you add 10% ethanol to the tank, it's going to require roughly 3.8% MORE fuel to...

    You want to be between 11.5 - 12:1 on a gasoline calibrated WB, closer to 12 is making more power but heat too. Do a quick MAF tune and you should be good to go. Make sure IFR table is right

    Like Murph is saying, any amount of ethanol in the fuel needs to be accounted for in the tune as these cars don't have ethanol sensors to adjust fueling on the fly like the "flex fuel" cars do. That...

    I took the belt off my SC and was watching nearly 40* at WOT (since NA puts me at a different area in the timing table, ie not the .92 column). Of course, I was still commanding SC'ed AFR's so the...

    Any wideband with a 5v analog output will work fine.. :) You can read the reviews and figure out what one you like best. PLX is a nice brand.

    You are likely out of luck aside from taking it to a dealer. HPT's licensing system checks the VIN/VCM ID on the ECM before flashing it and if there isn't one there, it won't flash it. While it...

    Are you sure the narrowband sensor is a +/-5v input? I would have thought it was 1v :/

    Anyway, if you want to figure out what the PID.### is, click the ? mark above where the "function" goes.

    Yeah that will be a good MAF. Those are LS1 mafs unless SLP changed them. Should be good to roughly 300 whp's worth of airflow until you need to scale it back.
