Finally!

MoncefA33 · 10-06-2009, 05:57 PM

So after months of waiting, attempted hardwire, testing, shipping, and TWO harnesses...

...my GReddy e-Manage Ultimate is now running my VQ30.

I'd like to thank everyone here, especially DandyMax, Product of Korea, whilmi, and MOHFPro90 for helping me with every step.

Hopefully I can start tuning soon, my wideband isn't plugged in yet but I'll be able to sort that out when I feel like pulling my shifter trim/gauge out.

Just saying that Maxima.org is a great place for the performance minded. I couldn't have done this without the help from dozens of members.

MOHFpro90 · 10-06-2009, 05:58 PM

Win.

*Conrad283* · 10-06-2009, 06:48 PM

Congrats

*TDotMax* · 10-06-2009, 07:00 PM

Congrats! Great to see things coming along

MoncefA33 · 10-06-2009, 08:23 PM

Thanks guys.

Hopefully I can get a feel for the software and possibly do some tuning tonight. If it stops raining...

After a short test drive, the car felt better because of the tune that was on it I think. Better top-end, went from high 10s to high 11s AFR. Still need to pull more fuel though. The two-step rev limit is awesome also

Ya dude, I know you're looking at getting an EU, if you do, hit up MOHFPro90 for a plug n' play harness cuz that is FTW right there.

shadyonedeath · 10-06-2009, 09:20 PM

whats this with your trim/gauge u need to take out before wide band?

MoncefA33 · 10-06-2009, 09:22 PM

See where I have my wideband gauge mounted? That piece comes out with the shifter trim, and I need to plug the signal outputs into the back of the WB gauge and hook them upto the EU.

SES light?

MoncefA33 · 10-07-2009, 12:12 AM

P0500 from vehicle speed sensor. When we did the headers I'm not sure if the connector on the gearbox was reconnected completely cuz my buddy was helping me and disconnected it

Gemner · 10-07-2009, 01:53 AM

if you dont have an SES youre not doin it right

whlimi · 10-07-2009, 06:13 AM

Congrats! Glad everything finally came together for you.

Time to email me some logs

Are you referring to P1320? Maybe he's got the resistors soldered in the EU or patch harness.

Im sure I don't have a P1320 cuz the resistors are soldered into the harness.

Haha, yes definitely. I wanna give raising the rev limiter a try! Street tuning is kinda tough though, need dyno

questions: What are you guys running for ignition timing maps? About how far can I advance it on 93 pump gas?

perkman87 · 10-07-2009, 07:28 AM

i could have done that in like 20 minnnzz

Nice work Dude.

What you could do is get a base map in third gear. Do 2 or 3 runs for accuracy. This way we'll know what your stock ignition curve looks like at WOT.

After that, the best thing would be to go to a dyno and play with timing to see how much advance nets you the most power.

*secondtonone317* · 10-07-2009, 09:07 AM

congrats, nice

Sounds good, Ill give that a try.

Whlimi, how did you tune your AFR? Did you use the I/J or airflow adjustment map? And does airflow adjustment mapping indirectly advance the timing if you pull fuel, like the AFCs?

Im looking to do either a flat 12.8 AFR or 13.0 dipping down to 12.8-12.5 after 5000rpm.

Use the I/J map. Adjust the injector pulse width (duration) with respect to MAF voltage and not Throttle Position.

You dont need to make any adjustments to the airflow map unless you go with a custom big bore maf and need to adjust the maf voltage.

Product_Of_Korea · 10-07-2009, 04:26 PM

Glad to see you finally got it.

And to think you got ripped off

Kyle did a good job on that patch harness. I likey alot. So when is he going to mass produce them haha.

Just wait till you extend your rev limit and get your timing down. It will be a diffrent car.

And +1 on what whlimi said. Dont use TP to tune. Use duration and Maf voltages for everything.

Im very pleased to see all these guys pull together to help you out man. Gotta give props to the community

MoncefA33 · 10-07-2009, 06:14 PM

Thanks Andy, you were def a big part of it for sure

Okay I'll keep that in mind. I'm gonna have to switch the jumper setting for the fan circuit and afterwards I'll start logging and get rid of the airflow map that the previous owner used to tune on.

I'll get the AFR down and then timing. Thanks a lot Maxima.org. Updates coming.

Man I'm such a newb with this stuff lol. The guy doing my dyno said he'll teach me how to use the EU which is slowly looking like not this year

In all reality it isnt that difficult to use the EU. Its actually pretty straight forward. Once you actually have one and used it. Its really simple.

I posted in your thread. Hope you dont mind but i offered my fried ECU and pigtails up there. But if you want i can sell them directly to you as well. IIRC i have two pig tails and one ecu. I might have two ecus though im not totally sure though

MoncefA33 · 10-08-2009, 11:00 AM

EU looks scary at first because of the 16x16 cell maps

but I'm sure it's easy to get the hang of.

MoncefA33 · 10-11-2009, 11:19 PM

UPDATE

http://www.filedropper.com/2ndgearlog

Got a datalog of Ignition timing, AFR, and I/J pulsewidth in 2nd gear to redline.

EUers, peek and help me with some initial tuning decisions

Thank you!

Thank you!

If your WB is calibrated properly, you need to start pulling fuel at around 4000 rpm right to redline. Your AFR is in the low 11s and high 10s at some spots.

Also read this thread: First AFR/Timing Map, Opinions Please!

There's some good information on timing advance from some of the gurus.
For some reason, on my EU software it shows that your speed starts off at 130km/h and peaks at 431km/h lol...

MoncefA33 · 10-12-2009, 10:19 AM

Okay that sounds good.

What MAF voltage should I start pulling fuel at? Thanks , Ill take a look at the thread.

Lol, that's what my EU software said too. That's why I did 2nd gear instead of 3rd

You have to do a map trace to figure out what cell in the I/J map needs the adjustments. Open up the I/J map along with the logged run and when you left click on the map, a red vertical line will appear there. That cell will also be highlighted in red on the I/J map and that's where you will need to pull fuel. Dandymax explains this very clearly in his EU writeup.

As for the speed, did you setup the vehicle information correctly in the EU software? I'm guessing your vehicle speed pulse setting might be off.

MoncefA33 · 10-12-2009, 11:12 AM

Oh, okay thanks. I'll check the EU writeup too. Whoops I forgot about that

The parameters were the same as per the '00 Maxima that it was in before me. I'll double check those.

84wagon · 10-12-2009, 11:33 AM

sweet! if i cant get my 84 going i may replace the comp.will that work on an ooold sys.

Unfortunately no, this is a piggyback engine computer which means it cannot operate by itself. It can only operate when it's connected to a functioning factory ECU.

MoncefA33 · 10-14-2009, 05:52 PM

UPDATE guys, got some tuning done.

Datalog:
http://www.filedropper.com/lim

Car runs mid 12s AFR till the rev-limiter then goes to 10 flat (still need to work that out) But I'm happy with the fuel adjustments upto the rev limit.

Now for ignition timing: I did some reading and saw what people have said about how much total timing you can use at redline only. How about timing advance across the board?

If someone with more experience could step in and give me some pointers, that'd be great.

*TDotMax* · 10-15-2009, 05:20 AM

Bump that redline up!

MoncefA33 · 10-15-2009, 10:49 AM

Haha already did

Nice, how's the car when you hit the stock rev limiter?

MoncefA33 · 10-16-2009, 08:04 AM

There's a noticeable dip in power since my Injector PW's go upto like 12.8 ms at redline but shortly afterwards it pulls like a freight train. I was shocked how hard it pulled up there on stock cams, it was fantastic. I plan on getting the power dip worked out as best I can and tuning after the factory rev limiter. 75mph in 2nd gear is delicious.

TDotMax, do you know if the stock ECU fuel maps go past 6,500rpm? I'm trying to figure this out cuz if you look at my I/J map it shows 8.00 ms at 7,000rpm, I did this because I wasn't sure if I was supposed to input a regular correction factor or a full out injector PW. At this point the AFR is low 10s, so I'll probably be backing it off a little.

One more thing, does the ignition cut rev limit work? Like you can see my rev limit was pushed back to 7,500 but what if I only want like 7,200?

Product_Of_Korea · 10-16-2009, 11:21 AM

you can try and make the rpm point a little closer. IE instead of going from 6500 to 7000 try shorten up the rev points from like 6500-6700. this will also make your rev limiter smoother as well. That way you can fine tune a little better up past the limter a little better as well.

The stock ECU does not have fuel maps past the rev limter. Thats how the stock rev limiter works it cuts fuel. So that is why you need to put in the full pulse width in after the limiter.

Cutting the ignition should work as a secondary rev limiter. I have never tried it but i belive there are members who have used this method.

MoncefA33 · 10-16-2009, 11:27 AM

How do I change the rpm scales by the way?

Okay, sounds good

POK, do you still have your fuel maps from when you ran your DE-K? I'd like to look at how you did your rev limiter increase.

Thanks,

Moncef

Product_Of_Korea · 10-16-2009, 12:45 PM

up at the top of the map it has a button that says "change scale"

Here is one that i have untuned dont pay to much attention to the fuel This is more for the rpms

Note how close my rpms are. I didnt have to much of a lag at the stock limiter.

I have a tuned map but its in the EU that i sold a couple of weeks ago
