Nah it will go away. I did this too and check engine light came on.

I just turn the car off for like 2 mins and turn it back on. Sometimes it takes 2 or 3 tries but it will go away. Always has for me at least

or unplug ecu fuse


or use torque android app.


either way ecu will be reset

Thanks! It took me three tries.

Been running the new stg2OFH tune on my car for a few weeks now just live monitoring data seems to be doing healthy, so decided to datalog it on the track this weekend for few laps and 3rd gear pull (time 17 to 31.2sec in the datalog below).
Mods on the car: Greddy intake (MAF scaled using @steve99 greddy MAF scale guide), Tomei UEL header, Nameless 2.5" Overpipe and Frontpipe, Tomei Type80 catback.
Other slight tweaks to the stg2OFH tune that i did other than MAF rescaling was @Wayno radiator fans tweak and @steve99 tweaks for reduced bogging in low RPM (under 2k) with high load in primary open loop fueling, and throttle response tip-in enrichment from 2.4ms to 1.6ms.
Here's the datalog from the few laps on the track and 3rd gear pull (time 17 to 31.2sec): http://www.datazap.me/u/rebel2010/td...1?log=0&data=1
If @steve99 and @Wayno and any others could please take a look and see if the tune is running healthy, would greatly appreciate it
From what i noticed FBKC is pretty much constantly at 0, IAM is constantly at 1 and never seen it drop below 1. The only thing i noticed which seems a bit weird to me is during 3rd gear pull both FBKC and FLKC are 0 however later on during the laps FBKC stays at 0, but you see some FLKC from 6400-7400RPM, is this an issue?
Sorry for the long post, any feedback is greatly appreciated.

Looks to be a touch too aggressive for extended track abuse but likely perfect everywhere else.

FWIW the old 91 octane Stage 2 tune I'm using never knocks on the street but gets little blips (-0.65) here and there on track even with 93 octane fuel.

Up to you if you want the slight extra risk of the small-ish FLKC you're seeing on track for the extra performance everywhere else.

thanks for the fast reply
Ye it's the only time i've noticed any FLKC, but just weird that FBKC is constantly at 0 and IAM is always 1. Using 94 octane btw. Just wondering if it is safe to run with occasional track (2-3 times a season).

[D_Thissen]

I'd say so man. -0.67 isn't a whole lot of knock. If you want, you could always pull a little bit of timing from those areas and that should help. I wouldn't worry too much though.

It's actually not weird at all. Just means the computer is not recording enough knock to dial back IAM. It's a good thing. I've looked at the new OFH tune's ignition temp compensation tables, and its decently aggressive in dialing back timing for high temps. Looks like you are getting some FLKC past 6400rpm as the engine starts to warm up past normal operating temps (guessing since you are not logging any temps). You can trim back a half a degree or so at a time on the areas of 1.0 load and up from 6400~7200 where you are seeing more than -1FLKC if you want more knock resistance.

[DocWalt]

That's exactly what I'd do. Back down timing a little when it's really hot on track. Best of both worlds.

Tried flashing the new OFH tune on my car:

- JDL catless UEL / OP
- Berk catted FP
- Perrin CBE

Drove 30 minutes on the highway to build some LTFTs, then logged a few pulls.

First impressions are it feels stronger than the old tune I was using (v. 2.074). It appears it's not running as rich as before and there's more ignition timing at the top of the RPM range (previously tapered to 25* at redline, now holds nearly 30*). I do see slightly more FLKC and KC on the log, but nothing alarming so undecided whether I'm going to use this at the track or not.

Going to do a few more data logs in the coming weeks and see how LTFT's and FLKC/KC looks.

That pull in the 2nd log seems a little lean? And what was ambient temp?

Doesn't look bad. Definitely more aggressive and a touch on the lean side. I'd drive it until the LTFTs are fully set and see what the AFR looks like at WOT and maybe add a touch of fuel if it stays that lean (I'd prefer to see it at the command AFR or slightly richer for safety, it's not like we're out there trying to win races and set lap records)

Yeah I noticed my LTFT in the 5000-7400 RPM range changed from +1.56 --> -1.56 in between those runs. That would explain why the first run was slightly rich and the second was slightly lean. Most likely my LTFT's are still adjusting. FWIW on the previous tune, LTFT settled around +2 to +3 in that range (and slightly rich).

Ambient temps were 70-75 F. Intake temps were 95-100 F.

BUT I WANT THAT HPDE TROPHY! Hahaha. Yeah I'm thinking the same thing as you, I'll let LTFT's settle and see how things look before June 11-12.

I will say, I'm getting less of that fuel smell around town so that's nice. I wonder if any changes were made to MAF scaling or if this tune just runs leaner for some reason.

Highly recommend you run a higher octane at the track than what your tune was set up for, if at all possible. Extra insurance.
