The Datalogit groups appears to be a waste of time, so I'll try the tried and true method with you guys. I was wondering if you could answer some basic questions that the manual failed to give.

What is the difference between basic and advanced feautres logged off the datalogit?

Can someone tell me if they have found a way to tap into a Dynojet Wideband from the dyno and input into the datalogit? I'm too poor to afford my own O2, and plan to tune at the dyno with their wideband.

Hooking up for an RPM/torque reading to the dyno seems to be impossible for the people running the dyno (domestic shop). I assume just read off of a leading plug wire and calibrate for a V6?

Going to the dyno tomorrow and would like to have these simple questions answered. Thanks a lot.

The Datalogit group has a good (but small) talent pool. Give them time to answer your question (which I saw, but I don't know the difference myself and am interested in the answer, too). They don't monitor it like the other lists/forums yet. This forum will usually get you quick answers, but many of those are bogus

The only way I know to get the wideband tapped in is through the AN1-4 box suppied with the datalogit. The dyno shop would need to splice off leads and wire up to the box. Doesn't seem likely that they would do that for you.

The easiest way to go is to get your own wideband - best $1K I ever spent.

good luck on the dyno.

Take a look at the monitor screen and you will see the different parameters that are logged with the basic and advanced sets.

I usually log both but mostly use the basic knock and the wideband. Basic knock is consistently higher than the advanced knock and closer to the Commander values for peak knock. Sometimes its handy to have the both.

Local Mobile Dynojet operator has the O2 hook-up. It's the exact same sensor as is suggested for the TechEdge...the NTK. We have used the unit and screwed it into bungs in the DP and MP. Have not tried to capture output after the heater/control circuits. Would be simple test with a voltmeter and you could use the TE's NTK sensor polynomial. Nice idea.

I have logged the advanced and basic features and it's very plain to see which are consistantly higher, I guess I should rephrase my question. What exactly is it factoring into an advanced reading? My guess is that it takes an average within a given amount of time and then from there determines if the knock "spikes" to be able to keep knock separate from drivetrain noise etc...

As for the dyno and wideband issue... Looks like I'll just compare graphs with where my AFR are because it would be a pretty good amount of research to figure out how to tap into the wideband and get it logged into the datalogit. Not to mention the damn dyno has kept me waiting yet another day (6 days) telling me the new O2 will be ready and this is the 3rd appointment they have broken... <sigh>

That $1k seems like it was very well spent!

It realy is. I'll get to see the results based on my next dyno run. 330.6 rwhp on a dynapack was my last reading, before doing wideband tuning on the road (almost every night I'm logging, adjusting, then downloading and starting over). It's allowed me to pull out .7 from most of my original settings in the p19 area and pull my afr's from below 10 to avg. between 10.5 and 11 (still tweeking), and still know I'm running safely.

I"m less than 400 miles from an oil change - that's when my shop will take it over to the dyno for a 'redo'. I might take the day off and go with them. Trying to become the first guy to hit 400 rwhp on upgraded twins using the stock manifold. So far no one's been able to do that.

Just curious what your other mods are Beast? Also, I know of a car that ceases to exist, unfortunately, that hit 392.5rwhp on stock twins... Where are you from as well?

Anyone reading this thread, don't hesitate from answering questions if you know the answer...

Well, I'm in the Sacramento, CA area. I'm running the first prototype hybrid turbos from Checkpoint. There are t-60 type ball bearing cartridges running in a custom machined stock turbo manifold, non-seq, with the pre-spool plumbing rewelded to turn the old pre-spool door into a second internal wastegate. 1300cc secondaries, intake, dp, resonated mp, M2 Medium SMIC, pfc, hks twin power, pulley, datalogit, Techedge DIY wideband, Pettit boost controller, M2 AD coilovers, toe-links, trailing links, Unobtainium diff bushings, Mazdacomp bushings front and rear ... ugh, the list goes on and on.

Currently running at the upper limit of the stock MAP sensor (1.13 kg/cm^2 = 16 psi). Right after breaking in the motor, but before starting my tuning, we did a prelim run of 330.6rwhp on a dynapack, with afr's under 10. I have the Apexi 3 bar MAP sensor on the shelf waiting to go in after the next dyno run at 16 psi, with afrs close to 11. I think 17 to 18 psi is all I can go on pump gas with 10.5 afrs. After that it's gonna take race gas (and a Profec B so I can have two settings for boost). Maybe an aquamist system, too.

Lots of skeptics out there on whether the hybrid twins can do it (rightfully so). I'm just trying to slowly get there.

Sorry I don't know the difference between Basic and Advanced - they tend to be close to one another and I have no idea how they differ. I go off of advanced because.....it's advanced, therefore it's got to be
better.
