So i finally got fed up with the crap 91 here in AZ, switched to E85(smell is awesome! lol), found out we have more stations specially where I live now.
http://www.datazap.me/u/hlhachiroku/...&zoom=968-1044 WOT run so far. Running a little rich still or is that within acceptable range? Looks really smooth vs my 91 maps I think atleast. The driving around, its up and down ALOT lol. Is there a way to have it want less commanded afr? I keep seeing 50.00 for the ignition advance some times at cruise on the freeway/in town cruising, that normal on the E85? lol @steve99 Thanks for the input.

I'm still learning things so I apologize in advance.
I'm wondering if the 93 gas I'm using is not very good. I was on the OFT stage 1 93 tune for a couple days and my advanced multiplier dropped down to 0.79. I've seen some FLKC and Kock Correction before but this is the first time I saw the multiplier drop. Here are the 2 logs when it dropped. Unfortunately the first log ran out when it started dropping so you're missing some data from when it goes from 0.9 to 0.79. Also I think I logged everything that is relevant. http://www.datazap.me/u/randomfool/5...zoom=8118-9940 http://www.datazap.me/u/randomfool/6...4-11-12&solo=5 And just because I was curious I flashed back to the stock tune. I never did a log on it and wanted to see if it knocked at all on that. The multiplier eventually back up to 1 but then drops to 0.9 at one point. Here is that log. http://www.datazap.me/u/randomfool/s...4-11-12&solo=5 One thing to note is first 2 logs were done during the day and the stock log was at night so intake temps different by a good amount. Also my car is stock except a drop-in filter and catback exhaust. My question for someone more knowledgeable than me is should the multiplier drop at all on the stock tune if you are using 93? Could the knock on the stage 1 tune just be from higher intake temps? Should I not not worry about that much knock on the stage 1 tune? What about stock? And last I know I could modify the stage 1 tune to pull timing in that RPM/load range but I plan on going on the E85 tune when my tank is empty. I'm just trying to learn more and incase I use 93 in the winter if I should go somewhere else. Thanks =) |

yes when you off throttle you will se high ignition advance values have a look at the base timing b table and the knock correct max a add those two togeather for the loiad\rpm your at for total ignition advance. |

all you knock seems to be in the 2000-3500 rpm area engine loads 0.6 to 1.1 you could just remove a around a degree of timing in that area. also maybe look at the Intake air compensation and maybe make it a bit more agressive arround the 87 to 90 odd degree area |

Here's my log (warning: it's huge, I jammed my 3rd gear pulls, cruise, and some spirited driving into one big log) http://www.datazap.me/u/gawesome/201...1&solo=0-10-14 Note: The first and third sections are a bunch of WOT 3rd gear pulls. The last two sections was me trying to get some positive FLKC to recover my IAM by doing a lot of low throttle pulls. My IAM is essentially a wild rollercoaster ride So I think it's safe to say that OFT tunes are too aggressive for catted headers? I get consistent knock corrections around 3000 to 5000 rpm. I applied Wayno's base timing B, and knock correction A and AVCS tables already. Safe to say my next step is to start removing timing at those rpm ranges using kodename47's knock correction tools? |

@G-awesome Looks like you're still getting a ton of FLKC even with the IAM under 0.7. More than earlier logs you posted. I recall seeing one of your logs that was relatively free of flkc with IAM at 1.0. Is the fuel different from that log? If so, whatever fuel you were using there was probably much better than the current one.
http://www.datazap.me/u/gawesome/201...om=12316-12508 The LTFT looks good staying within +- 2-3%, only going past -3% during off throttle decel. With as much knock correcting as you are seeing, Id suggest using one of the stg1 ignition advance tables designed for use with 91 or 98ron petrol as starting point.

Here's a 3rd gear pull from your log (12.2:1~11.2:1 afr): http://www.datazap.me/u/gawesome/201...70-12357-12417 Here's on of mine (12.7:1 ~ 12.2:1 w/no knock correction): http://datazap.me/u/solidone/z6-kc1-...81-290-300-311 I don't think it's the AFR's that causing the knock corrections, but I could be wrong.

So after talking to a buddy last week who is was at the track testing shivs new OFH tune(with a tomei uel) I decided to give it a shot. Heres a quick 2nd gear pull (I know 3rd would be better but this is the best I could do for now).

93 oct, stock airbox, panel filter, cnt uel, top speed OP, recently released OFH stage2 tune, approx 80 degrees, all runs within 10 minutes each other. ran at least all of 3rd at WOT & some of 4th @ WOT.
http://www.datazap.me/u/n8brz/brz?log=0&data=1 http://www.datazap.me/u/n8brz/brz?log=1&data=1 http://www.datazap.me/u/n8brz/brz?log=2&data=1 please take a look and share your knowledge. are there any other channels I should be recording and any that are unnecessary? i intend to do a follow up when weather gets a bit hotter out in the middle of the afternoon. rarely run the engine hard enough like one would during track time. Thank You, |

You have up to -2.6 knock correction at higher rpm fairly consistently, looks like that tune is a bit to aggressive for your setup, it was specificly for ofh header. you might be better with the "standard" oft UEL tune. It also running a bit too rich midrange and upper rpm. |
