Anybody ECUTEK getting Check Engine lights?
 
I wondered if the car is safe to track next season if I'm still getting intermittent CEL @ certain RPM / throttle.

:ugh2:

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

SouthArk370Z 12-20-2015 01:42 PM

Depends on what is causing the CEL. An OBD/CAN scanner should tell you.

OBD scanner has no saved codes on the ECU The engine is counting some misfires... But not enough to store a code... still searching.

P.S. The dash only displays CEL under certain conditions.

By chance, does your CEL light quickly flutter at part throttle when going up hill?

Hotrodz 12-20-2015 02:12 PM

Under hard acceleration you will get the flashing check engine light. It's normal and happens to me every time I accelerate hard...I'm boosted though and Seb told me not to worry about it unless it stays on!

Part-throttle and not necessarily uphill.
But 1/2 throttle and 3-4K RPM

And yes... The CEL "flickers" at that time.

Yeah, I get this from time-to-time, but I've done multiple scans and never found any codes. Mine will do it anywhere between 1/4 and 1/2 throttle, around the same RPM you mentioned. It doesn't seem to do it any more, so I haven't given it much thought. It seems to have rectified itself. As Hotrodz mentioned, unless it stays on permanently, or for long periods, I wouldn't worry about it.

Hotrodz 12-20-2015 02:27 PM

I didn't have my gas cap secured correctly once and it would flash, but at a different pace. It would flash consistently at any speed. So, I think it's just one of the small glitches in the system.

osbornsm 12-20-2015 02:38 PM

Well... It's the knock sensor, not really a small glitch for us HPDE folks.

Oh, this is on the least aggressive Map

Still searching

Hotrodz 12-20-2015 02:39 PM

LOL...come on now it's no different for us boosted folks...really I got $20k into my engine upgrades so don't think that I don't take this stuff seriously.

Edit: Mine to and Seb is a very conservative tuner and my tune is mild and on the rich side of things!

This is a feature of RaceRom

Visual knock warning - Provides knock warning by flashing the "check engine" light when knock is detected.

Does it do it on all four of your maps? What octane are you running?

Yes it is...we are only giving feedback on our experiences and you should always consult with your tuner on their tune and what you may see or witness in your vehicle. If Osbornsm tuner tends to tune on the lean side then I think there is reason to be concerned, but I have no information on that so all I can comment on is what my tuner has relayed to me about my situation. It's just information and you can do with it what you please.

I have 3 maps and a valet. Occurs on the least aggressive Map... More so on the others.

Running 93 octane since birth. Not even 91 lol

Mine happens on all maps of mine as well and even when I'm running straight e85 so I don't think it is a fuel type issue. What I think is happening is that when there is load on the engine, the change in AFRs and fuel pressure looks like knocking to the ecuteck programming and you get the flashing light. 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?

Hotrodz 12-20-2015 06:00 PM

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.

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 :tiphat:

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.

dP3NGU1N 12-21-2015 01:16 PM

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

ban25 01-14-2016 12:52 PM

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.
