It will be nice to have the knock logging but even at 40 deg I haven't had any knocking yet but of course thats N/A. I will use if for sure when I install my liquid supercharger.

 

Hehehe..

I have the KS run in on the analog input, so I can see the waveform and indirectly correlate if I have knock - assuming you can separate what's noise from what isn't. But I haven't had any knock either...

 

Liquid supercharger?

 

Need to get a group buy for EU and harness

 

Yeah, and from an Authorized Dealer as well... Get working on it. LOL

 

Just thought I'd post some information for reference sake...

I have been running around with the MAF out of the car lately and just using a pressure sensor. I have been doing some tuning this weekend and now have the car tuned for a range of air temps. I can report that driveability is still just as good as ever, and I have no problems driving in closed loop or open loop. In fact I cannot tell the difference from before (with the MAF). The AFR's are consistently where I want them to be now that I have made some adjustments for air temps (from almost freezing up to around 80F so far). And I have also tuned each bank individually under WOT so my AFR is consistent bank to bank and across a decent range of air temps. The key to this is setting up a good conversion (airflow output) map to start with though.

Also made another discovery: playing around with the rev limit extension stuff I have found that on our cars the rev limit cut map is unecessary. That is, the rev limit can be extended smoothy using only the injector map. My theory is that this is because the ECU does not completely cut fuel, it just shortens the pulsewidths a great deal down to around ~1ms, but as long as there's a signal, all that's necessary to go past the rev limit is to provide fuel via the I/J map. I have now discontinued use of the rev limit map.

On a final note, I have been trying to get hold of Greddy to find out WTF is taking so long with the update but no luck yet. Even version 2.0 beta has bugs to be worked out yet...

 

Does that mean that Emanage Blue can do this as well? That would be good for those who already have it.

 

Great news on the MAP....

Eliminating the RLC map should make extending the limiter much simpler. Can't wait for more people to start hacking on the EU and figuring out new ways to improve the Maxima knowledge.

Keep up the great job Dandy.

 

I don't think it's that simple. I cannot say for 100% sure because I do not have a Blue, but when I read through the manual for it I don't see it being that easy. Furthermore, I seem to have deleted the PM I had but IIRC it has been tried to some degree and didn't work (by someone very knowledgeable on here with whom I have conversed on this topic previously).

On the Blue it looks like the Additional Injection Map does not allow enough adjustability to provide enough fuel past 6500. And using the Sub Injector channels would be tricky: you'd have to use 2 channels to control 6 injectors, they would only fire in batch mode... I'm not sure what it would take to make that work and the EB doesn't have a crank/cam sync either. In the first case you'd probably need to generate some kind of external signal (oscillator maybe?) to piggyback the AI map on. More trouble than it's worth if you ask me considering the additional controls the EU can give.

 

I don't have either, but I thought it might be possible. If that is the case then that is still one more advantage Ultimate has over blue, but since we don't need the RLC map I thought it could still happen.

For that kind of trouble you had might as well upgrade to EMU.

 

Dan are you just using the airflow adjustment map with the MAP and extending the rev limiter or are you using the I/J adjustment map for the rev limiter? My airflow adjustment map is already maxed at 5.0 for stock rpm at 6k so nowhere to go for extending the limiter unless I use the I/J map.

 

You have to use the airflow output map to run without the MAF. I basically created a full RPM vs airflow vs pressure conversion map. After that, then I tuned in different air temps and made adjustments to the fueling so that my AFR's stay the same across different air temps.

For the rev limiter, I am just using the I/J map and adding the necessary fuel past 6500. The RLC map can be deselected/inactivated.

 

Ya I have been running MAFless for the past while too, just not above stock limiter so will try the I/J map.

Finally got my BFG's whipped in shape for this weekend where I have to run street legal tires.

 

Haha nice!Didn't they have more tread last time I saw them?

 

Tread?? I need tread? Some folks shave them new just to get to this point.

I think I may have worn a bit off testing on the road.

 

Hehe yeah I knew what you were doing I was just teasin...

Actually mine still do have a fair amount of tread, haven't raced on them much... but then I haven't been racing any street tire events...

 

OT but since you are active in this thread I'm going to ask it. Dandy and Jime how far are you guys from Windsor, Ontario? Windsor is not too far from me of course, right over by detroit and it only takes me about 2.5 hours to get to detroit.

 

I am about 2.5 - 3 hrs, Jim is another 1.75-2 from me... so ~5 for him.

 

Any particular reason you ask Neal?

 

Yeah because I was hoping you were not too far from there because you guys are both knowledgeable guys and you both like to go to the track. I drive 3.5-4 hours to go to the track usually a couple times a year the other direction (west to byron dragway).

 

Grand Bend would be our closest track to you Neal its around an hour or so from Detroit. For me its 3 hours and 2 or less for Dan. Would be nice to meet up sometime. How far is the closest track to Detroit?

Easy on the knowledgeable stuff, I have never been accused of that before.

 

Yeah that sounds like a good idea.. would be fun, make a weekend of it and meet up somewhere.

 

Any word on the Update Dandy ?? Its been Months now

-matt

 

Version 2.0 has now officially been released. (about time!!)

You can get it from mohdparts or from Greddy's official site.

Happy tuning!

 

When I update, what do I have to change on the settings ??

-matt

 

Choose the crank signal under "RPM signal" on the vehicle setup tab (if you have not already done so).

On another note, will try to reply to your PM tonight. Just unbelievably busy dealing with my move to a new place this week plus other pressing things. Darnit I got finish my EU writeup too....

 

Here's a list of what was done for version 2.00 (directly translated via Babelfish so interpret at your own risk - bold font is my interpretation):

E-manage Ultimate ver.2.00

what does this mean to maxima owners

 

It means every feature should work fine now off the crank signal and everyone has access to it, making the EU fully usable by the entire community.

(And basically for the most part it signals the end of my long campaign with Greddy which started in August, 2005).

 

To anyone who is trying to tune with a MAP sensor you will notice that there is a very jagged graph which makes it hard to tune. Mine varies by as much as 8 kpa.

By installing an inline fuel filter or some other device to buffer the signal it will smooth out the graph considerably. My variation dropped to 1 kpa. The jaggies are probably caused by the pressure waves in the manifold.

 

Cant get it to run under crank signal. "Crank Angle"> Runs really rough, and rich and no read-out for RPM on the datalogger.

-matt

 

Yes good point Jim. All that's needed is a small plastic storage tank/canister or enough hose area/length to dampen the pressure wave sensitivity.

 

do you have a pic of the setup you used?

 

Its just temporarily in place to test it, I just cut the line from the intake to the MAP sensor and inserted a cheap plastic fuel filter.

 

hey guys i dont mean to hack the thread but you guys know best with the EU. As dan knows im having this installed this week but hte installer ran into some problems. Here the email he sent me..

These are the problems I am having.
1-The car wont start with the EU tied into the Maf sensor. If I bypass
only the Maf to the EU, it will start.
2- I have no Maf out voltage as per EU datalogs. While cranking I am
getting 1-1.2v input to the EU
3-I have no RPM signal. I am running it based off of crank angle. I am
using the crank position sensor and crank referance sensor for getting
the signals. I
have swithced both of those wires around and there is no difference.
4- The EU circuit board is different than what is shown in the manual.
Jumpers 9, and 13-16 are in different locations.
5- The datalogs have odd characters. Where it should say Contents, A,
B, Units there are odd charaters instead. Where temp should be there is
the normal F for fahrenheit, but right before it there is an
es-zett(german character for a sharp S)
6-In the parameters tab, under I/J I dont have the normal heading of
CH, Type, Map1, Map2, Type, Timing. There are just more add characters.

I have double and triple checked all my wiring, and the jumpers in the
EU. I am confident that all are ok. I updated to the newest 2.0 and
those issues are still there.

I have tried to post/search/pm on Maxima.org but it wont let me do
anything even after I registered. If you have any other forums or
people I can contact, just let me know. Right now I am at a standstill
until I can get some more information. I can not get a real person on
the line at Greddy right now.


If anyone could help out with this or if you think i need to start a new thread i will.

I SHOULD HAVE BOUGHT A SUBARU

 

He called me and left a message, which I got and called him back, but got voicemail, so I left him a message again.

I have a couple thoughts and questions but will have to talk to him to find out some specifics of what he's done.

EDIT: talked to him on the phone now...

 

Would the fuel damper on the DEK fuel rail be sufficient you think?

 

This is Andy from Xotic Motorsports, I am doing the EU install for Tom.

So here is where I am at right now. The maf issue is fixed, I had the air flow output map on instead of air flow adjustment map.

I am still getting the odd characters in the datalogs and I/J parameters tab. I have set the software back to 1.09 and worked my way back to 2.0 with no changes.


There is a screen shot of what the characters are.

The tach in the dash does not work and I can not get an RPM signal to the EU running crank ref.

Any help would be greatly appreciated.

Andy

 

Holy funkyness... I have never seen or heard of anyone having that gibberish before on any car! That almost looks like a laptop/Windows issue. Have you tried a different computer/laptop, or check your font settings? If I look at those characters I think they are part of the "Wingdings" font, (check out the character map under Accessories, System Tools). In fact if I convert the word "Type" to Windings, I get the characters you are seeing in the 2nd column from the end.

Is that gibberish showing up across several windows or just on the I/J tab? Maybe check into that and I'll see if there is some kind of font definition file for the EU.

For the rpm issue:
-do you have the tach wire connected to the EU as well as the crank lines? If so, I would disconnect the tach wire. It is not needed either with or without the crank, as the EU can also read rpms using the coil pulses like a dyno does.
-on the main vehicle setup tab, what are your selections? (you should only have to choose vq30det for the engine code, and then pick the crank under rpm pickup type.

And it might be helpful to post all the jumper settings too...

Dan

 

I would agree that there is a font issue. But I use this laptop to tune alot of systems, AEM EMS, Hydra, EcuTek, Hydra, Utec, Hondata, Chrome, Hp Tuners, and Emanage Blue(not currently installed), and have not ever had an issue like this. It only happends on the Datalogs and the I/J tab of parameters. Everything else is formated the way it should be. I will look into the font def file for the EU.

The Brown RPM wire is/has not been hooked to the vehicle harness. I am only using the crank position sensor and crank referance signal. I configured the parameters exactly like you had in the first post of this thread.

Jumper settings are as follows. This is taken right off the board as I set it up and not from my notes.

JP1-6 open
JP7 1-2
JP8 1-2
JP9 open
JP10 open
JP11 open
JP12 open
JP13 1-2
JP14 open
JP15 have set to 1-2, 2-3 with no effect
JP16 open
JP17 1-2
JP18 open
JP19 1-2
JP20 1-2

The only jumpers that I am questionable on are JP7/8. I did not want to move them to the 12v setting until I had confiramtion that it would be ok.
