Data Logs! Post them here.

In my datalog http://datazap.me/u/raviolig/10115?log=0&data=1-8
The 2nd and 3rd pulls cause the LTFTs to creep up to +10.

Like mentioned above, could it be due to an exhaust leak?

I have a trackday next week and just want to make sure my car is 100% beforehand.

I don't know why people who don't know what fuel trims are for are always flipping out over them. They're supposed to be variable, that's what they're for.

If your AFR is above 12, which it is, you're fine.

Hurr durrr thank you almighty fuel trim overlord I am not worthy

How you get these logs from your car?

[sav]

Tactrix cable or Openflash tablet.

Can I get it out with ECUTEK Pro Ecu Programming Kit?

I need to send my tuner my logs thats why im asking and I get home from working trip this weekend!

[sav]

EcuTek? You can yes, I'm just not sure how it works exactly.

Do you know how should I install the wideband gauge (AEM UEGO 30-4110) that my car ECU logs right 0-5V output?

Or correct me if im far a way from right way!

Sorry for off-topic!!

I had high LTFT like that when I had a leak at the header/OP connection..like Wayno said your car looks to be running fine, but it wouldn't hurt to test for leaks so you know you're running optimally.

Using tactrix, and B01C ROM.. Quite new to this. Got the OTS Stg 1 rom flashed, and learning to look at logs, but seems like it may be reading wrong?

EDIT, heres the datazap

http://datazap.me/u/joe-g/reupload?log=0&data=16

the first logcfg.txt file in the tactrix post wont work correctly as its for A00C/A01C roms

you need to use the B01C logcfg.txt file, each time new roms are complied the ram addresses for logging change

B00C_B01C_logcfg.txt


looks like your using correct file but some of parameters not logging.

you might have to ask some of the other guys on B01C rom if they have sorted out those parameters

This sort of thing is why you pay the extra for an OFT :-) as its all sorted for you

Try this for B01C

Thanks for the help. Played around with it a bit, think I got it working :P

looks a lot better the engine load parameter is wrong it should be values between 0 and about 1.3.

about 0.2 at idle and increasing with throttle application to about 1.3

maybe try parameters from other B01C file i posted up

Looks a lot better. Still have to make some adjustments I guess, but overall it looks like Im on the right track.

Thanks again! You've been so much help!

@Wayno @steve99 @Kodename47

here's my newest log with the injector scales, UEL load limits, and my custom maf scale (done with injector scales, but before adding load limits). I'm pretty knock free but it looks to be running too lean compared to commanded.

http://datazap.me/u/joshbustos86/jdl...-4-6-7-8-10-13

My custom scale is richer than the stage 1 scale above 3V (where my AFR's were just about spot on without load limits) so I'm now wondering why it's leaner, as I'm not hitting the load limit past 4000 rpm.

here's my maf scale (top) vs stg1 (bottom)
