Excellent work, look forward to your thread! Love the new experimenting and hoping it all works out great for you and achieve even better results.

That sucks no timing data logging

drothgeb

Yeah, it intercepts and modifies the factory MAP sensor signal for fuel, and CPS for timing.

Thanks! Running good for a few days now, playing with some minor street tuning now.

Yeah, real bummer. I E-Mailed their US and Polish(home) tech support. The US support got back to me quickly but seemed very confused by the question, first telling me it wasn't necessary to see what actual ignition timing was and started talking about a different product, then when I clarified that they were talking about the wrong product, they responded and started talking about dangerous ignition voltages as if I was wanting to connect to a damn spark plug wire. I think the brains of the operation are in Poland and the "EcumasterUSA" folks are just a sales team. The Poland support email has not responded back. Pretty sure I know the answer though. I did pull one of the knock sensors into an aux input and I'll see if I can get anything good from there. I know there are a few threads on here that talk about how noisy and difficult the sensors are, with no usable data. But the DET has a few things as well as frequency input/filtering that I can play with to see if I can make sense of anything out of the sensor. But for now it's back to watching toque timing logs for knock

As always good customer support is key with everything. Using a system like this could be an expensive disaster if you don't have the correct knowledge back ground with electronics and how an engine should run.
On a side note what do you run for fuel??

drothgeb

I have various tunes from all the tuners, the one I'm using right now spikes mid 11s early down to 11ish at redline. I'm trying to work on fuel slowly right now because I don't know how much each adjustment will affect fuel. The steps are adjustable with each unit added or removed from .0049V to .0195V. I have it set on .0195V and have pulled a little bit of fuel but it's not been enough to see yet (the highest cells I have currently are -4).

Timing was easy to see it works! Did a run, logged timing with torque, set all timing cells to -2 degrees, watched torque again and saw 2 degrees less timing across the board haha. So that's good news.

I'd like to fine tune timing as much as I can, knock limited and get AFR squared away around 11.5 across the board but without a good way to see if i have knock the timing is a bit of a crap shoot.

SICAMG

Your doing a great job. It takes ***** to do this stuff and we have all....some of us, been there, to test new things on a perfectly good running car !!!
I can't tell you how many times I have had transmissions and valve body's out to tweak and adjust to get it just right. !!! Labor of love with this stuff I guess !

drothgeb

Thanks man, got the new thread going but calling it quits for the night: https://mbworld.org/forums/w211-amg/...ml#post8130716

Got a great new lead on a way to monitor knock though. KnocksenseMS ties into existing knock sensor or sensors, runs an LED light, and produces a 0-5v analog knock detection output. I'm waiting on a response from the seller but will pull the trigger as soon as he sends paypal info haha. Fingers crossed he still makes them. http://www.viatrack.ca/

Man excellent stuff. Very keen to see basically how safe your current tune is you running.. Nice t see the unit working perfectly pulling the requested 2 degrees of timing out, at least now you can trust it from that point of view. Hopefully the knock light setup will work perfectly to for when you start adding your timing. Will also be interesting to see what extra timing you can throw at it for running meth or octane booster of sorts.

@drothgeb how has the car been running on that DTK tune? Now that we're into cooler weather have you seen that hiccup issue return at all?

bobgodd

I'd like to go with a 82mm throttle body, if it's a worthwhile upgrade, but the information is scattered and it's really hard to tell if it's a reliable upgrade or not. I searched the thread and did not see anyone mention whether the throttle body sensor adaptations were reset via DAS after installing. Is this something that's just "a given" and nobody is mentioning it, or is it not common practice when people are installing the throttle bodies?

SICAMG

If you are not sure go with the 80mm and you will be fine. I was told this many times and did it with no issues. I also did a throttle shaft grind to pick a few cfm up as well.

drothgeb

Been running great. I have not had the hiccup one time ever with the DTK tune on. Now I can never go back to EC or RaceIQ lol :-[

bobgodd

I found this video and was wondering if this is something everyone is doing, because I can't really find it specifically mentioned.

SICAMG

I just did the manual reset with no issues, no Star reset.
But that works too !

drothgeb

Yes I've done it. Does not fix the 82mm hiccup for those unfortunate enough to be plagued by it. In that video the "rotor adaptation" page he's looking at is for the CPS and flywheel and is not related to the throttle body, it is anoying to get them relearned and in my experience the car may suffer from "false" misfires until the common ranges are appropriately learned. It's also believed the throttle body stops relearning that's mentioned on the reset page can be done manually.

bobgodd

Thanks! I'm just trying to get a full understanding of what's involved so I can decide if I'm game, and it's been difficult trying to piece together all of the information.

My issue only really come up under an almost specific condition below is my usual test of re-tunes to see if the tune has resolved the hiccup issue:

Start car let idle drop before driving
Cruise from 70-90 MPH with a pull once warmed up to get some boost
Cruise from 80-90 MPH on south I35 into a head wind
Felt first hiccup and saw STFTs stay high (highlighted in orange in log sheet)
Continued south until I found a safe place to pull over
Let car idle for a few minutes noticing the car having the rough idle like it was trying to stay in idle
Turned car off, removed key, opened door and waited a few minutes
Restarted car and headed back to Austin on I35 north
Cruising at 80-90mph felt slight hiccup an saw check engine light come one

That stretch of road and driving conditions will trigger the hiccup almost 100% of the time (depending on traffic conditions as I need to stay at 80+ for a while without slowing down). Those speeds and terrain might be why some folks do not experience a hiccup, it also seems like a majority of the conversations have moved to facebook which kinda sucks for those of us without it.

I *almost* wonder if there is a ram air effect at those speeds and with the 82mm throttlebody that is contributing to the hiccup but that is just speculation. At this point since I've tried 3 used 82mm throttlebodies I've been recommended to try a BRAND NEW 82 to start with a known good working throttlebody. If you are on the facebook groups you might pose the question there to see if folks have an issue.

With as many 90mm throttlebodies being promoted around here I'm surprised that none of those folks have experienced the hiccup.

drothgeb

It appears to be random as to which cars experience the issue. Maybe ECU or firmware related or something, who knows.

But, I verified it's not related to the stock intake/potential ram air type deal by switching the factory intake with the green mushroom filter straight off the throttle body. Same issue.

lost27

Figures I reply to this thread and find out that the throttlebody I've been running starts idling low 1.2-2 TPS today and throws a P0505 :/ Looks like I'll be biting the bullet on a brand new one much sooner than expected

drothgeb

Is it an 82mm throttebody? That is very possibly just an air leak and not related to what's being discussed here. No one has fixed the problem discussed in this thread with a brand new throttle body, unless they were going back to factory size from 82.

lost27

Yea, it is an 82mm... my third used one. It had been running fine (aside from the P0106 hiccup) since May with TPS between 2-2.4%. This recent issue just came up today.
