You just need to open the csv in a spreadsheet program like Excel and remove the 1st few rows before the data headers. Then everything will work dandy

just keep the maf curve smooth

look at the open loop data and the closed loop data in that area and come to a compromise in the middle is usually a good starting point

Thank you both for answering.

Hmm. Do you have any hints where I can gather further information about load limits?

have a lok at wayno,s tune thread in software tuning it has suggested load limit mods, you might need to update your definitions to see trhem though

@steve99 any insight on why I've gone rich?

If thats an oft e85 tune it look pretty normal ,they do tend to run richer than commanded afr with the standard maf scaling.
if you have a leak it mist be a small one

you can rescale the maf to make it run to the commanded afr if you have a stable e% source of e85, the oft guys make it run rich for safety.

Hey guys! I'm looking for some input as this is the first datalog I've posted and only third datalog that I've actually done. I just flashed the stage 1 93 tune after I had installed my grimmspeed intake. I'm waiting on the grimmspeed tune from the OFT guys because I can't get the files to load in RomRaider and I'm not sure I'm brave enough to edit things yet since I'm still learning. Any input on the datalog would be greatly appreciated!

Would also like some input, I just got the OFT yesterday and flashed the Stg 2 93 UEL tune paired with the OFH and a drop-in filter. I logged a 2nd gear pull and some normal driving.

I've loaded Wayno's stage 1 mods, not including the ones for startup noise.
There is absolutely no knock correction on a warm morning, so I'm thinking I could get a bit more aggressive with the timing, just need a suggestion as to a starting point.
Also, should I tweak the MAF scaling?
The car has no hardware mods that affect anything but sound. Axle back (mostly done for looks, I hated the tiny exhaust tips it came with) and sound tube delete.


Thanks

Your WOT pulls were running lean. Don't go WOT immediately after flashing, especially with an aftermarket intake and unscaled MAF. You need to wait for ECU to learn LTFTs - do some highway driving.

AFRs look great.
You've got some occasional knock you might want to address. Might be due to high temps or bad fuel.

Thanks! Yea temps are high here and fuel isn't exactly great in my area. I'm hoping that's the case.

I just filled up on my first tank of E85 yesterday (possibly E70), I've logged a few throughout the day to get the residual petrol gets out. The adv multiplier was below 1 but in logs 3 & 4 straightened back to 1. LTFT ranges between -3.91 to -7.81. Are things starting to look normal? I will be taking it out later to do some more logging.

Negative LTFTs are normal with residual 93. Over the next several fill ups it'll get to zero and maybe beyond if you have good E%.

Thanks for the feedback! Since I'm a total noob to this what should LTFTs be around? 0? I haven't figures out RomRaider yet but this way I'd at least know what to kind of look and watch for.

And for the WOT pulls I did those after driving around normal for a few days which was before I did this datalog. Is that enough time for the ECU to learn?

is your intake stock ?
are you running E85 or petrol tune ?
