17743 - Engine Torque Monitor 2: Control Limit Exceeded

[RexPelagi]

Ok, This has been on the tex for weeks and they are clueless as usual.

I have gotten this code 5 times now in the last month.  4 were at various speeds on the highway, most of them legalish, and one was at 20mph.

With the code comes fuel cutoff and an EPC light, the only remedy being cycleing the key on and off.  The code appears to be one that will only trigger a cel with 3 or more times, so I have had 1 cel from this code.

The full code as it reads in vagcom is
17743 - Engine Torque Monitor 2: Control Limit Exceeded
P1335 - 35-10 - - - Intermittent

Car is a 2001 Jetta code AWD, 032 CL ecu.
Relavent mods are: Revo Stage 1, GHL CAI, GHL 2.5in DP with Cutout (was opened/closed makes no difference), Green Top TS, and a Ko3s swapped in.

The best I can come up with is a software issue, but I have had the software for a year, and the code only started in the last month.  It is quite annoying to be going 80 and lose all power, so lets hear ideas.

I sent a message to revo, so I am expecting either no response from them or them to blame it on hardware (ture or not, time will tell I suppose).

PS, Im not sure where this is supposed to be, so if it is supposed to be in the general 1.8t tuning than someone just move it

I'm suspecting your MAF is going bad or possibly your O2. You may want to try and unplug the MAF for a while and adjust your fuel trims to suit via Lemmiwinks and proceed with trying to re-produce the problem.

Please report back.

That isn't a bad idea, I will probably give it a try.  However the maf and primary o2 are only a year old.  I did run some watered down race gas in the car a twice, would that have been enough to kill an o2?  It was about 7gals total of turbo blue @ 2:1 gas to turboblue.

[Don®]

It may have although I'm not familiar with turboblue. 1st try without the MAF if incase it works fine without the MAF then I suggest you get a new MAF and if you can an O2.

Typical dub style, whatever the problem unplug the maf.  How should I adjust the fuel on that, lean it out abit?  With the price of gas, and knowing that I can't reproduce this on demand, I kinda want to make sure I wont kill my gas mileage.  Will lemiwinks adapt out whatever I change?

John,
    Your email was forwarded to me from our UK office. It looks like the
problems you are having are due to improper hardware for the software you
have. Our Stage1 software was tuned and designed around a basically stock
vehicle. Although the K03-sport turbo isn't too much bigger than a K03 (what
originally came on that car), it is significant enough to throw off the
software due to the increased power. The software was tuned around a K03
turbo with specific boost/power curves; now with the larger K03-sport turbo,
the values aren't reading what is expected and is throwing that code.
    You may be able to tune some of this out with lemmiwinks, but support
for that is limited if not non-existent.
 
Thanks,

Yep, I guess the software can't handle the mad uber power of a ko3sport , even though I have had the ko3 sport on for 8 months and the code only started a month ago.

[Don®]

Your LW settings will not adapt out.

[RexPelagi]

So if I wanted to edit fuel for example, that wont get adapted out?  Everyone seemed to think it would? 

Im not sure what revo is suggesting I adjust in their software, but I will probably try the maf first.  What would need to be adjusted to run without a maf for awhile?

[Don®]

After driving the car for a while without the MAF you will have to check your trims block 032 and tweak the Primary Fuel tweak with LW to suit your trims so you can continue driving without the MAF till you know for certian that the MAF is the culprit.

FYI, I hit that code several times on GIAC X+ and the stock K03S (that the software was written for).

Did you ever figure out how to not get it or did you just live with it?

Also, I have heard several people have gotten this code with giac in different forms on different turbos, but I haven't seen anyone say they got it with revo, so I really don't know what to think about this.

[Pass_it]

i get this code with unitronic BT 630 S/w as well, it has happened twice spread out over about 2 months.  Does anyone know what would cause this?

[v84lnch]

clean your maf john.

[RexPelagi]

I did a TBA a few days ago, and the code hasn't come back yet.  It was always kinda random though, so I'll keep you posted on what happens.

NVM, same thing again, maf is next.

[Dizzy]

Whenever I have gotten the code, there have been no ill effects.  No EPC light, no CEL, etc.   Just the code stored.  It has happened once on Uni 630/AWP file as well but that was when tuning the EBC and it's never come back.   Maybe Mike Z could chime in here. 

[RexPelagi]

Ok, this isht got unbareable on the way to a friends place.  I hit fuel cut no less than 30 times on a 40 min trip.  It was f***ing ridiculous.  The thing is, I was cruising at 70-80, and was very easy on the engine, so this code to me has absolutely no merit as any sort of torque monitor.  Have the time it happened i was on decel, so low to no load at all.

Half of that time I had the maf unplugged, still got the fuel cut just shitty gas mileage.  It has never ever been this bad, and it seems to be getting worse and worse.

Also, on the way back (closed course of course) I was going 125+ and I got fuel cut twice, when the engine was ACTUALLY under load.  What gives guys?

[RexPelagi]

A new code came up after the fuel cuts last night,

16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
        P0130 - 35-10 - - - Intermittent

Could the primary o2 be the culprit of all these problems?  The car still preforms fine it just gets fuel cut so I don't get it.

[TurboGTiandZX12R]

IF you have a BOV vented to the air or a like in the recirc pipe you will get this code. I remeber this from my BOV days with stock turbo and APR 93. Decel would make the code pop up all the time.

[addo]

i had;

17743 - Engine Torque Monitor 2: Control Limit Exceeded
P1335 - 35-10 - - - Intermittent


And it was a result of my Maf not being securely mounted and being bumped around. As soon as i fixed it the tip from moving about it solved the problem immediately "so far 2000miles". The new issue is do i weld a bracket to hold it on the engine that has almost rigid engine mounts or on the inside next to the suspension strut again i have very stiff suspension. But like i say it solved it straight away with my temporarily secure mounting.
 

[RexPelagi]

I logged timing advance and retard, it didn't look pretty, Im not sure why.  But the whole time I was logging I saw 6 degrees of retard (had it advanced 1.5 with lemmi) so I backed it back to the stock revo level, and the code didn't come back yet.  This code seems to be sort of a B.S. code, because it obviously has nothing to do with load or torque, otherwise it wouldn't happen on decel, part throttle, and cruise.  I think it just depends on the car.  Not saying my solution even did it, could be something random, and it definitly isn't constant on all cars/softwares.  I've heard of other people chasing this code on AWD's for some time, usually finding the maf, but that seemed to do nothing for me. Anyway, if I find out any mroe info I will let you guys know.

[got_boost]

not sure if anyone found a fix for this yet but just recently i have gotten this CEL as well,both times cruising on the highway under no load or very light load.since i have the laptop with me at all times i stored the codes every time and this is what turned up--

so maybe it is a MAF replacement code 

[RexPelagi]

Based on my research and what other people have said, I don't think there is a blanket answer for this code.  It almost sounds like this is kind of like a human's reaction of throwing up, as in if the eyes see you spinning and your inner ear says your still, your brain comes up with the best solution it can think of. 

Its almost like the car just decides 'meh, I'm cashing out for now, peace'  It was so random in my case, I mean 30 times in as many minutes, no one I have found had anywhere near that type of experience with this code.

For you it could very well be your maf, or maybe a dv, I do remember people saying that a loss of air between the maf and map would cause this, for me it seemed like it was timing, but it could be something like the weather and my car just didnt like it.  I couldn't reproduce it on demand, but I know it happened with or without the maf plugged in, leading me to believe, at least in my case, that it wasn't the maf.  It hadnt happened in 300miles when I took the timing down, so I don't know what to tell you. 

In all my experiences with this it has to be one of the most unhelpful codes I have ever seen.  No vagtechs had any idea about it, at least the ones I asked, and I asked some of my ASE certified friends and they had never heard of this code on my platform or any other.
