Direct Link tuning info?

[Powerglides]

John raises a relevant point regarding tech support, and this was an important factor when I started dyno tuning EFI some years ago. However proficient we ultimately become, there is a point that we have to start from where we actually know very little. Since I do this as part of my business, the initial learning curve needed to be both rapid and intense. Whilst I had many years experience with engine building and tuning carbs and ignitions, I was under no illusion as to the amount of support I would likely need.
At this time there were 3 products available, SEPST, TTS, and DL. Bear in mind that I am in the UK, and on a different time zone. SEPST has no tech support over her outside the dealer network, and very little within it, and TTS phone support is only available to me at the end of my working day. DL, however, is marketed in Europe by Gerrit Vosselman (similar time zone) who is also an accomplished dyno tuner, as well as a bit of a whizz with computers. Most of my early questions were caused by lack of computer skills on my part, as well as lack of familiarity with the software, and the use of Teamviewer whilst talking on the phone was a godsend to getting everything clicking into place. Didn't take long, but saved me so much time. Its surprising how much time can be wasted going round in circles due to overlooking basic stuff. The other significant feature was the live data logging whilst the tuning tables were open. This remains a very useful feature of DL and, looking back, I feel this was a great asset at the start of the learning curve.
One thing that still needs addressing, I feel, is a proper tuning manual. The information that came with the old SERT, the rewritten SEPST version, and TTS, are way in front in this respect.
Whilst I do feel a sense of loyalty to the product (as others no doubt do to there chosen device) I am not blinkered to other developments. However, I have been in this business a long time, and I have to say that the tech support that I've had, and continue to receive, is probably the best I've yet experienced. No doubt we all get stuck from time to time, or notice anomalies when new calibration levels are introduced, and its useful being able to compare notes directly. I'm very much in my comfort zone with DL.

Maybe Techno/Sandro would be willing to join our forum to offer some background and answer some technical questions and specifics of their product.
These are some pretty smart fellers IMO and have a ton of HD EFI experience starting with the infamous Magneti Marelli EFI.
It would be potentially is a great source of info since we lost SC.
Hopefully they will be interested to join us,

Doubt that would happen but you never know, they do post on facebook almost every day.  He likely has seen the light and realizes there is more to be gained by manning the ship at the business office.  It will be interesting to see how the new MM stuff works as he has told me he has done some reprogramming stuff that gives it a target table like the Delphi.  I maybe see one MM bike for every 20 Delphi  but it would still be nice to have a reliable system with manufacturer support for those few. From interacting with both I can tell you Sandro and SC are as different as night and day, thank god for that.

BV,
I just tuned an M&M bike with Direct link and it now works just like the Delphi. Autocreate/map works and there is a target AFR table that you fill out. The rear being an offset, it takes the live data from the front cylinder and that becomes the target for the rear offset. Works very well and they also updated the stepper motor voltage so when you turn the bike off it will show you the final setting in volts so setting up the cold idle is pretty simple now.

I bought a Direct Link Super Pro today. I think I need a cheaper hobby.

Did you get the combo?  I like mine and it is a great addition to the shop. If for nothing else.  Centurion with all the DT feature is great.  How do you plan on using it?  I'm sure it can be used for street tuning, but....

[Coyote]

I got everything but with a mind to just use the DT features. They also threw in a  tuning key to give it a try. From what I understood, tuning on the road is very easy and the unit uses a phone for the display. I also heard they should release soon the ability to do a flash on a virgin ecm.

I wanted to be able to assign key fobs and marry TSSMs as needed and it should do all that. I hope to be able to work with them some on a way to recover TSSMs where the PIN and key fobs are lost. RIght now, if you don't have one of those the TSSM is bricked.

[hrdtail78]

The virgin ECM is coming.  Another nice feature for my shop is the ability to turn on the rear fader of the radio.  We install a lot of 35 pin connectors for lower fairing speakers.  It's nice to pull of the rear channel instead of splitting front 4 ways.  Nice product with nice customer service.

DL can receive inputs from different wideband controllers, that are selected from the Options menu. currently the following can be used,
TR-M300
LM1
LC1
Wego (DTT)
UEGO (AEM)
AFM-1000
M-300 (PLX)
SM-AFR (PLX)
Dynapro 2000
Superflow
Delphi stock O2
Wideband Commander

I have a Twin Scan/ WEGO set up, but I want to switch to a system that allows for a longer record time.  I'm thinking about buying the Centurion/Direct Link system to use as a wide band data collection system, but the AFR meters that I'm considering doesn't seem supported.  I need a setting that supports 0-5V = 9-16 AFR.  I searched each of the above noted controllers and none seemed to have that range.  I tried using the software to see if that range was supported, but without the Centurion I can only view the standard Centurion software that only allows for a controller that is 0-5v = 10-20 afr.  Can anyone with the system check to see if the range I need is supported? 

here's the system that I want to use to sample afr:
Powerdex AFX

anyone currently using that meter with the Technoresearch system?

I sent web link question to Technoresearch over the weekend, but they haven't responded yet.

Give Sandro a call at techno and tell him what you want and he can probably add a controller to the list.

[mayor]

I think I may do that, and if he can I think I'm sold. 

I didn't see any papers scheduled for Techno Research at the Vtwin show this year.  Are they planning any?   

[eddfive]

I have not asked but I am sure they will do something. Another thing to ask Sandro.

[mayor]

you going again this year Ed?

[eddfive]

Proabably not

Why not just use the dual channel Wego setup with the digital display? I can't imagine the price difference being that much.  Sandro can likely answer your question on the spot concerning the Powerdex system.

[hrdtail78]

IIRC there was a post concerning that system w/ DL and it got turned on or it was just used in place of the wego. 

Maybe a post up in his vendor section.  He might explain it and we can all read it.

I talked to Sandro yesterday. He said he will add that controller to the list.     Since I already have the controllers and the Centurion is the only system I can think of that will allow for correlating those sensors to a HD ecm, looks like I'm all in on the Techno Research system. I haven't bought the system yet, but I may soon.   

[eddfive]

Good call, I use it all the time. The Centurion is pretty powerful stuff now with all the features.

[mayor]

Why not just use the dual channel Wego setup with the digital display? I can't imagine the price difference being that much. 

I already have two single channel digital display WEGO111's afr meters, an older dual channel WEGO11D, and the twins scan system.  I like these units, but there's a few things that I see as being an advantage to changing to the Centurion system with the Powerdex meters.   The main advantages that I see is the longer allowable sampling record time, the Powerdex uses a  NTK sensor, and the scaling should help give a more accurate reading.   I like that rather than 1 afr being equal to .5v like the systems that 0-5v = 10-20afr, one afr is equal to about .71v with the 0-5v = 9-16 afr.  I may be thinking this wrong, but I think that all things considered I should be able to have accurate results.   

[hrdtail78]

Longer same rates is a good thing, but with DL you log with the computer. Wouldn't that be the limiting factor?  Same as logging data with TS on a computer.  The log file can be as big as the computer will allow.

[mayor]

I've not done any long term recording of Twin Scan data on a computer yet, but from what I understand the same time limit is there for some reason.

[strokerjlk]

Nope use the data buffer ( computer )  . Not the twin scan to store your data .
If you have a complete twin scan wego , with sensors . I might be interested in trading my direct link for it .

[hrdtail78]

Either way with 20-25 minute dyno sessions is not going to be a problem at the fastest rate.  Or I haven't had a problem yet.  With DL you wont have that problem at all.  The data isn't collected into a buffer.  It is recorded onto the computer.

you saying there's no recording limit with Twin Scan if I save on the computer rather than use built in storage?  I'll have to try that next week end.  I'm pretty sure the directions read as if there is still the same record limit.

I'm not too interested in getting rid of my DTT stuff.  I think there's times where that would still come in handy.
