I'm no expert and I may be overly simplifying it, but that is how it was explained to me.

I find it somewhat odd that the company which wrote the software wouldn't allow for changes in air/fuel or pressure. Seems like you were talked out of a fix?

Nope, everything is fine and I think it's part of what you get when you have new software, there are small things that are annoying and sometimes scacy. So far critical things have been addressed. I am totally confident in the system and my tune. It always helps when there are others with similar concerns as you walk through the fire together. This has been a journey for me since buying the car 3.5 year ago and it seems with every mod there is always some little thing that one has to accept like noise with SPL parts or hiss and rattling with race pipes. It's all part of the modding game.

Or also... Is this "normal" activity?

u are on winterized gas this time of the year.. probably getting slight knocking? if fuel is the culprit, then u should be fine around april..

Can anyone confirm if the check engine light flicker happens on the stock map? Reason I ask is in Commiefornia you will fail smog if the CE light comes on = no tags issued.

Thanks

Mine never flickered on the base map before getting tuned.

When I got my EcuTek installed my engine kept taking a sh!t and loosing ALL power every 3 miles. Check engine light and a few other lights came on. It would just stay at 500rpms. I would have to turn the car off, wait a minutes or two, turn it back on and it would do it again. I reached back out to Seb at Specialty Z and he sent me a better file. Now the car drives like a DREAM.

Might just be a bad file or one with glitches like mine at first.

I've had the flashing check engine light. Was also told it was knock sensor by my tuner. Subsequent tunes have been better but still comes on every once in a while and not as readily reproducible.

It seemed to primarily happen at low RPM (2k-3k rpm) if I decide to accelerate without downshifting on the earlier tune.

I think we three have the same tuner...

I don't think so. I'm not using Seb. So this seems to be a characteristic of the software and not an issue with the tuner per se.

Hotrodz · 12-21-2015, 02:57 PM

Got it, and that is what I have been saying all along. It's a system thing.

100% believe it can be "glitchy". Seb is the man and after we reinstalled it with a few tweaks its PERFECT!. No track time yet, but I will in Jan.

Hotrodz · 12-21-2015, 03:56 PM

He didn't mention that in particular, but he told me cleared up some of the other issues for you as well. The tweaks are different being boosted so I still have the issues surrounding launch control, so I just don't use that map other than to show off lol.

Nice! So glad I live close to specialty Z they do such great work! I remember when we needed to fix it he came in on his day off to help me. very simple fix and my Z feels EPIC...probably no where close to your TT kit though lol

My car was tuned by Seb (thanks!) and I have gotten the knock indicator to flash occasionally on 91 octane. Practically speaking, however, I almost never run 91. I usually run ~95 on the track in the morning, increasing progressively to 101 by the end of the day. Importantly, I've never triggered the knock sensor in probably 1000 miles on the track running at 95+ octane.
