i need to find the pinout for the ecu to tell ash what goes where.

does anyone have it?

can you email me at belikelucy@aol.com

 

what year are looking for? jwt has a PDF on their site with the 96 pinouts:

I think I have the other years lying around somewhere if you need a different one

 

thank you so much

 

h2kspig - don't hold your breath for this or you may end up turning blue! i don't doubt that Ash has the ability to do this at some point, however I bet it took him months and months just to do with the OBD-I ecus for the Z. The OBD-II maxima ECU is much harder to crack, in addition to there being fewer resources available for him to work with, and certainly less demand and thus less incentive for him to get it done. I would expect it to be many many months before we hear of major progress with this, reverse engineering a complicated and slow ECU like the A32 ecu is not an easy process even for someone as obviously skilled and dedicated as Ash is.

 

I emailed Ash, but he hasn't gotten back to me yet. I am still trying to get my ECU working. He said during Christmas alone, he had to send out 25 upgrade z32 ECUs!! And he sold several ZEMulators too. So he has to upgrade each of those ECUs by himself. I know he's been busy. I will let you guys know as soon as I find out something.

 

Very true Nealoc and subs. I have kind of put the ECU thing on hold for right now as much as it pains me. I sent my ECU to TS but they are having problems getting the rev limiter thing on 5speeds and I need that with the MEVI. So right now my ECU is sitting at TS and has been for a while. JWT takes too long (funny b/c TS is right now too) and it kind of expensive for what you get. ZEMulator is still an option if it comes out before TS gets done although I wouldn't think this to be possible but who knows.

I really need tires and a few other things like these motor mounts to be installed to I bought some rims and tires and I will be checking up on this when we get some more news.

oh and Bump

 

email i just recieved.

Steve,
Yes! Thanks for sending that to me. Unfortuantely I have not had the time
to put into the ECU yet as I am still getting a few things launched for my
new business, but this is on my priority list.

The ZEM doesn't require anything powerful at all to run. Even a Pentium
120Mhz laptop running windows 95 will work, as long as it has a USB and
serial port, you are good to go.

fyi

 

I don't want to burst anyone's bubble but if Ash hadn't even gotten an ECU pinout until Steve sent one, most likely he hasn't even started working on this. Sounds like he is making a ton of money with just Z32 ECU ROM's. The market just doesn't justify the time he would have to spend to get everything working for Maximas.

 

any update on this?

 

hrmm... i think us 5th gens would have more problems

 

so whats going on with this? Aaron, does he still need a test car? I just saw this link on the MaxMods page. Looks amazing if he gets it up and running.

 

I don't think he needs a test car. Ash is still working on getting this to work in the newer Z32s and my VE30DE Maxima. They virtually have the same ECU. I have my fingers crossed to have this ready by this winter. But, I've been saying that for two years now! I won't start piecing together my turbo kit until this thing works.

What's the MaxMods page? Never heard of that.

 

It's like a kind of user-editable index for mods for all gens of Maximas...

any updates?

 

Well, since July, I got in touch with Ash once and he is still working on it. But, I think I motivated him to get cracking once again on this VE Zem project. I think he stalled out for a little while. There aren't any promises on anything. This thing turns out to still be in the development phase. Me and Ash thought we had this thing figured out, but some surprises came up and it didn't work like we originally thought.

But Ash has a new idea and we will see how that works in the next couple weeks.

 

Does this mean I should get my 96 auto ecu back?

 

I don't know. That is something you might want to contact Ash about. If you do talk to him, give him a realistic estimate of how many 100s of people on the Maxima forum are interested in his ECU upgrade. And I am sure there are at least 5 people on this forum alone that want his Zemulator! Most are turbo'd and have no real way to tune right now.

He got caught up in some other projects he has going. But after I finally got in touch with him after trying for a long time, he told me some specifics about the project and how he has a new idea and he is going to get started on that. Some of our other ideas fell thru.

 

Educate me. What is the difference between this Zemulator and the Romulator? Are that not both emulators or ecu readers/writers? Or is it more about the programs which are used on these systems?

 

A ZEMulator is an ECU emulator PLUS killer software for tuning purposes! So it's a total tuning system!

A romulator is just another kind of emulator, but without the easy to understand software.

And just in case if you don't know, an emulator pretends to be the ECU's EPROM. You unplug the EPROM, plug in the emulator, and then it can pretend to be your EPROM. This can allow you to tune on the fly! No chip burning needed!

 

Aaron, did you ever get this system to work properly on a z32 ECU? I remember you using the ECU, but I wan't sure if you had the zemulator hooked up with it or not. Was it an N/A ecu or TT?

 

the zem uses a romulator. unless that's been changed since it came out. anything the zem does can be done by chipping or with the romulator or countless other emulators.

 

I was saying that the romulator is just a type of emulator. Same difference. But the ZEMulator uses an emulator and killer software to do what it does.

If you go out and buy a romulator right now, you can not do the same thing as the Zemulator can unless you write the software to match what Ash has done.

But, in essence, yes, a romulator can do the same thing as the Zemulator tuning system can. But I'd like to see someone else write the software that Ash has developed all by himself!

Also, you said that anything the Zem does can be done by chipping? I hope you didn't mean burning new chips everytime you want to make a slight fuel or timing adjustment. B/c if so, then nothing can be further from the truth. With chip burning, you can't alter maps while driving down the road. You can with the Zem. It's also kinda hard to datalog up to 11 sensors too with chip burning or using the Romulator, you can with the Zem.

Since the system was originally created for the z32 ECU, I first tried to swap in a z32 ECU NA Auto ECU in my car and get the Zemulator working. After doing a little tricking of the ECU itself and after installing a z32 MAF, I was able to get the car to run barely. Then, I added the Zemulator to the mix and tuned the car the best I could and got it to run a LOT better. But there was only one little issue that I couldn't solve 100%. The idling! The idle would fluctuate from 500 to 1300. The idle would dip down to 500 rpm and almost stall and 99% of the time, it would catch back up and never stall.

When I was on the gas, I got the car to run pretty well. I don't think I put enough effort in tuning my timing maps since I didn't have access to a dyno. If I did, I could spend a couple hours on the dyno with Ash and make those timing and fuel maps flawless. I was able to tune my fuel pretty well at the track and constant runs up and down the street. But, I was only able to tune my timing maps with my ears while driving up and down the street. I got it tuned decently.

I then went to the 1/4 mile track and tried to better my track times with this Zemulator. I was only able to match it! Keep in mind that I know how to adjust for all types of weather and track conditions so that I can compare track times. I ran 14.59 with the ZEMulator that day. It wasn't what I was expecting since I tuned it for a race fuel program. I had a wierd 60' time. So I know I wasn't making the power that I needed down low. But my mid and top end was just fine. During the same day, I disconnected the Zem and swapped all my stock ECU components back in and advanced my base timing and ran again. I ran 14.57 with a much better 60', but lower trap speed.

I feel that if I spent more time tuning with the Zem with the z32 ECU, that I could get it tuned properly. There was just this idling issue that annoyed me. So I have been determined to get the Zem to work in the stock VE ECU.

Down the page is a link to third party software using the romulator. It is a romulator plain and simple and Live edit or zworks or the romulator software will allow you to make realtime changes driving down the road.

Yes I am saying I can do the exact same thing with chips that the Zem does. I am referring to the "tuning" part of zemulator goes. In fact I could do more with a basic hex editor and chips than the zem can because it doesn't allow/show you to alter warm up maps, idle pulsewidths, idle timing, etc etc etc.... there are many more maps...... I know how to use a voltmeter if I want to know what my sensors are doing or for a bux I can buy a 30.00 data acq. It does the same thing. The zem doesn't maptrace any better than what you can calc by hand or figure out with a few simple column tests to determine where you are in the maps. It does have a nice manual for explaining how things work and it is packaged nicely. Anyway I do not wish to argue over it. I would rather help you figure your idle problem and get your car launching properly.

 

I gotcha. I am familiar with that link. The zem is the same thing, but with great software. There may be maps that the Zemulator doesn't show, but it definitely shows you all the maps needed to tune any kind of 300zx you may have flawlessly. It does show warm up maps, idle pulsewidths, and idle timing.

My idling issue was about a year and half ago. I have stopped trying to solve that. Me and Ash are just working on getting this to work with my own ECU instead of me having to swap in a 300zx ECU.

I know some people put down the ZEM for some reason when they realize that it's possible to do the same thing the Zem does for MUCH MUCH cheaper. But, I am just saying that the Zem is definitely worth the money b/c Ash did a fine job in developing the software and making everything in a nice neat package for you. You don't have to learn how to read the hex code, which I know nothing about.

I know I am not saying anything that you already don't know. I am just stating facts for others that may read this. I didn't mean to come off as argumentative.

 

Does the Zem allow you to adjust the temperature that the fans turn on at?

 

No it doesn't. But, that might be a decent idea. I'm sure it's something you can change in the ECU. But it's not programmed in the Zem software to do that.

I would just wire in a manual switch like I have. It will completely solve everything. But I highly recommend a coolant temp guage if you dont' have one. Check out my website for how to switch on your fans manually.

 

I just pull the A/C fuse and run the fans w/o the compressor.
