All three runs were made back to back with no adjusting. Still trying to get this logger figured out. I have the hard to use tunerstein software. I don't know how to get more data from each run?? I see other people's logs and they're all three of mine put together. Any way do yall have any suggestions for my setup??? Is it tuned okay? Can I tweak it anywhere? Thanks for all the help!!

Here are my AFC settings:

Hi -20 -22 -26 -26 -32 -33 -33 -29 -28 -36 -35 -37
1000 1600 2200 2800 3400 4000 4600 5200 5800 6400 7000 7800
Lo 11 -13 -16 -16 -18 -21 -22 -24 -26 -25 -25

Tell me what to adjust!!!!!!

Your o2's look a little rich and your timing looks really high for some reason, maybe log TPS next time and go from like 2500 to 7k in 3rd gear.

Did you log that at full throttle?

 

[TurboGeoff]

you are running richer than donald trump.

 

[tommyboy]

Did you log that at full throttle?

all three were full throttle

 

[turbolarry]

You should be getting more data then that. Are you using digital mode and fast log mode?

i'm using both of those but, not getting alot of data

AFC settings have been added, please tell me what to adjust, thanks.

 

[CanadianTSi]

try changing your 5200 and 5800 to about -34

 

[tommyboy]

thanks, any more suggestions??

 

[tommyboy]

i'm a newbie to all of this so sorry for the stupid questions. I know i'm running really rich, what would i have to do to lean it out? Make the negative's on the Hi less negative? (ie: -34>>-30) Thanks for all the help guys. Oh...........i bought this car with all the mods and current tune, i haven't touched anything on the afc.

 

[CanadianTSi]

Going more into the negative is taking away fuel.

It doesn't look like your running really rich all the time just around 5k, try doing what I said and then log some more runs.

The AFC changes the amount of airflow your car see (air flow converter ). Anyways, by going negative your removing the amount of air the ecu sees, and this in turn removes fuel. When you "add" airflow, your richening because the car sees more air so it adds more fuel.

 

[XtReMeToYz]

One more thing, after reading over that list again you might wanna look into getting and adjustable fuel pressure regulator. Sure, you can do without it, but it made my life easier when tuning the 660's because you can start by removing fuel with that before using the AFC to do so.

i thought i got a nice piece of ebay. an accufab adjustable with boost reference. i got dicked over b/c the gasket on the inside is shot and the screws to take it apart are all stripped. anyway, i put the thing on and it works fine at 20psi but then when i up the pressure to the stock 42 it starts spraying gas out of the seals. i have one on order from ongreen performance.

thanks for the info, i'll adjust it when i get off work then run some more logs tonight. i appreciate all the help!!!

 

[olmytsi]

how much boost r u running?

 

[tommyboy]

i was running about 18psi of boost. Made some runs last night. Then...................................I killed my car!!! Made a 3rd gear pull and at the end my car shutdown and gave me a CRANKSHAFT POSITION A SENSOR MALFUNCTION code!! If this is just the sensor since there is no other symptoms of crankwalk, how long does it usually take to get to the sensor and replace it? Thanks.

 

[tommyboy]

TTT suggestions????

 

[Logue]

i didn't read the first make sure theres no crankwalk.

the accessory belts have to come off and the crank pulley and the lower timing belt cover than the sensor is right there. a couple hours of work
