CEL with Visconti tune
 

Driving My car today and out of nowhere the CEL light and traction control light came on. One big problem with getting it fixed is that I was one of the first people with the tune as I was testing out the mileage for John. Therefore I don't have a cable and am no stuck with a car that threw its code and that I can't bring to the dealer. Now I'm not blaming John. The tune was and is great but what the hell do I do now. I can't flash it back to stock and if it's as big of a problem as everyone else who had this problem am I even going to have coverage on this. Really need John to pm on here. I called him but I understand how busy he is and how hard he is to reach. So if anyone else has this problem with the flash and found a solution please let me know as well as of John could you please get in touch with me.

I thought the Visconti tune was supposed to effectively act as a band-aid to the idle issue by raising idle speed by a couple of hundred RPMs. Guess not?

what codes?

Going to check the codes soon. Got in touch with John though and I should be able to borrow a cable from a shop around me. The car really doesn't feel any different though and no specific action caused it. Just freaking out because I can't be without a car for that long

They'll give you a loaner. I got a Yaris. Whooooo! :D

just curious - how many miles have you driven in total?

I'm under 21 I can't drive a loaner! An 2700 today

Just found the code I threw. P1449. Quick google search said its a evaporative check solenoid engine malfunction

clear it
let it cool
restart and see if it returns

Cleared it and nothin came back up. Gotta drive it some miles though to see

Drove it a bit and have awful bog/throttle response. Still no CEL light coming back on but definantly can't continue driving like this.

If you cleared the code by disconnecting the battery then the throttle response will be like that for a while until it "re-learns" the throttle mapping. P1449 - maybe the gas station attendant didn't screw on your gas cap all the way?

No didn't disconnect the battery. And that would explain a check engine light but not the traction control light. Gotta put some miles in order to get the CEL back because i can't drive the car like this. Had to ride the clutch at like 3k rpms before just to get up a little hill at a lifht

Some error codes will put your car into a "limp mode" depending on potential severity of the code, as well as if higher rpm can cause damage. Do a full clear by unplugging your battery for a few minutes, after, let the car idle for a few minutes to start to relearn the MAF. Take it on a short low rpm drive (5-10m) and then run it through the rev-range (3k, then down, 4k, then down, 5k, then down etc).

Right now the car shouldn't be in this "limp mode" though because there are no codes being thrown at the moment. The guy who checked my codes did say the car could be in limp mode but the code that was thrown should not have put it that way

I'm one of John's testers too and I have gotten a check engine light as well, but only when I bumped my GoPoint BT1 OBDII adapter. It throws the code U0073 (U0073 Control Module Communication Bus Off) and also throws the traction control light as well. I think, the traction control light will come one anytime the CEL does. IIRC, every thread about the CEL coming on, also involves the TC light as well. My CEL has NOTHING to do with the tune and everything to do with me bumping the adapter.

I had the wonky idle before the tune and I've been nervous reading all the threads about CELs and cam sensors, etc. So far I have 1600 miles on the tune (3800+ total on car).

I did a search on google for the code you got and it pulls a lot of stuff for IMA on Honda hybrids. The subaru stuff it finds is related to the gas cap and emissions. I'd make sure your gas cap is tight, reset the light, and see how it goes.

The bad cam issue codes are P0017, P0018, P0019 and some others.

I'll admit, I did gasp when I saw the thread title, but I think your car will be OK. Better safe than sorry though. Hopefully John gets his GB fulfilled and has extra cables because I want to get one so I can flash back if I need to.

Oh I don't blame the tune at all, I loved the tune, but with so many cars being messed up I am just freaking out. I'm going to try to head over to Prime Motors today to see if they could flash me back to stock and then I'll just go from there.

:scared0016:

First it was correlated to extreme bogging issues when coupled with an aftermarket intake, now the $950 Visconti tune is correlated to Check Engine Lights? Wow, scary stuff. :iono:

Checked the gas cap and it was tight, so cross that off the list.

And to this guy ^^^^ I never said his tune turned the check engine light on, but it is possible it could have.

We shouldn't jump to conclusions though.

That's why I used the word correlated.

Hope you get it worked out.

Intrested to see what the dealer will do/see

Going to see John tonight to so he can check the car out and see what's going on. Will post when I get back home later.

So I was playing around with my traction control trying turn it on and It wouldn't come on. I opened up where it is and it wasn't plugged in! It's been plugged in before as I've used it but it seems to have just come out somehow. So I plugge it back in so far everything seems normal and fixed. Gonna do a drivin cycle and see if it any codes are thrown again. So if anyone gets the code p1449. Check your traction control haha. Cheers

what on earth have you been doing or how have you been driving that would cause that connector to come loose.... that sounds like a first

Crazy stuff

I shift too hard lmao idk man. Maybe my sound system installer maybe messe it up or whoever installed my HIDS. But all seems well so far. Going to do a drive cycle and see if my CEL comes on.

Lol one case of a car coincidentally having the tune and throwing a CEL and you assume that it must be due to the tune??!!??!!

Scary stuff!!!

^^ I really tried to emphasize I wasn't blaming the tune. Whatever though

^Ya that is what I was getting at. But ALT BRZ thinks otherwise.

The tune is not the issue here.

Check the thread title again. Correlation =/= causation. I'm giving the OP the benefit of the doubt.

Your input was very helpful in this thread - thanks !

Please update your Tune features...

What this flash does -

Raises RPM Limit
Improve Fuel Economy
Adjusts Direct Injection / Port Injection Mixture
Adjusts Caming Timing
Smooths out Wide Open Throttle Fueling
Smooths Timing table
Unplugs Traction Control

;)

Check out my thread for my STG1 flash - it's in my signature ..

I got a check engine light last time I put my stock intake back on because I forgot to tighten one clamp (was in a rush). There was no traction control light. As soon as I tightened the clamp and turned the car off/on, it went away. So I don't think this is true.

Unfortunately, this is relatively impossible. CEL's happen when the ECU reads certain values from sensors. Typically, this is either an "out of bounds" value (a sensor is reporting a voltage that's not within expected spec in the ECU; e.g. cam advance problem) or a predetermined condition from multiple sensors that calculates out of spec to the ECU (One sensor reports one condition that conflicts with another sensor, both are within spec separately; e.g. My CEL. Engine was receiving a lot more air than the MAFS was reporting).

So it's highly unlikely that John's tune caused a CEL. He doesn't touch how the engine receives CELs. And I'm willing to bet the ECUTek tuning software won't allow him to run a part over spec; such as cam advancement. The only exception I can think of is RPM, of course. He can tell the ECU to let the motor rev past what it can handle, but even then. The CEL would be caused by the mechanical damage as a result.

I'm willing to bet he knows what he's doing and it sounds like there was a problem with your evap system.

Psst John - I think you missed the last line that he added to your STG1 description:

;)

Oh ahahahhahHhhh ;)

I turn my trac and slp off....damn thing turns it's self back on and wont stay off! it's like my passenger window switch & trac button conspire against me when I'm not around.

I'm not sure if it's normal for it to just turn back on and I'm not that far into the owners manual yet. "It's a real page turner" though.:brokenheart:
