yeah, i was checking out that zemulator. i wonder if i can use it on the vg30e though... i bet the ve30de's ecu is more like the vg30de(tt) in that it has two fuel maps, high octane and low octane. or, in other words, your main map and your safety map (from what i understand).

 

im waiting patiently

 

lol, and I tried to be secretive about it then BAM it all comes out hehehehe

hmmm
me thinks of another challenge for Aaron

 

1/2 way threw uninstalling my 5spd intake. unfortunately my allen wrenches do not like the 18" worth of 'breaker bar' I was putting on them, if that makes sense. I just piggy backed some wrenches over the allen wrench.

Now I'm starting to rethink porting it lol.
na

I've got the air compressor back at my house, and the digital camera, so hopefully I can have some fun pics up tonight.

 

It would never work with a VG30E ECU b/c they are SO different. The VE30DE and VG30DE ECUs are identical except for a couple terminals that are slightly different. No biggie ... I found a way around that. The only way I can get this to work is to swap in a z32 ECU and z32 MAFS. After some tuning and more research by Ash Powers with z1motorsports, he will be able to release this mod to all VE owners (not VGs), maybe without even swapping the MAFS.

But right now, I am being my own guinea pig and trying to make this work in my car the ghetto way. Once it works, then it's 'fine tuning time'.

 

Oh if you can think of an idea, chances are, I've really looked into it. But feel free to give me any ideas you may have no matter how stupid they may sound. I certainly can't take full credit for this z32 Zemulator idea. That award goes solely to Nismo87SE. He is FULL of ideas. hahaha

And I have PLENTY of new ideas that I have in the works and I might even have some in effect before my next track visit. I wish I was able to somewhat estimate the 1/4 mile times I am shooting for, but with this ECU thing, it's not possible. But mid 14s are safe to assume for this winter.

 

aaron, if i didn't give ya crap i wouldn't care. so think of it like that.

im here to help when ever ya need it mang. id love to see an auto break my time, since none of the other 5 spd guys seem to be able to do it.

 

Oh yeah, I'm definitely appreciative. I forgot, no VE has challenged your 14.3. WOW! And here I am only concerned about the NA 3L Auto 14.2 record. The faster Maximas get, the better an auto is for 1/4 mile times. 13 second 5 speeds aren't easy to drive on street tires.

 

I'm working on it. I need more $$$$

 

just remember that the fastest and most consistent drag cars are automatics

 

Be very carefull when porting the VG TB its alot thinnner than u think i messed up 1 TB going alittle farther than i shoulda i can get ya the exact measurments on how far u can go before cutting into the coolant channels and going right threw the side wall. Its not very fat thought!! So be carefull if its the only one u have!

 

so thats why they have leavers to shift gears?
or one gear only?

thats not auto, thats direct drive and sequential shift. neither fall into the auto catagory.

 

they make 1 speed drag cars (or are you talking about CVT?)

I know people use power glides (2spd). hmm.

Besides Brian was probably talking about trannys like a torque flight 727/46re, c4/c6, power glide, th350/400/700r4. Even if you put in a full manual valve body and all the nice fun stuff, its still an automatic.

 

Let me clarify. I was refering to bracket racers.
A functioning Auto will be more consistent than a stick.

 

Yeah. Bryan is thinking about top fuel maybe. Of course automatics are more consistant.

Anyway, about the VG throttle body, 90SEBlack is probably right. I'm glad you brought that up about the coolant jacket. I know the VE TB doesn't have one. But I've heard little stuff about the VG TB having a jacket that you can easily poke through. Good info 90SEBlack. If you can, please post your measurements for anybody else thinking about porting the VG TB.

 

how are they very different?

 

First off, the motor is not even CLOSE. Which would never work. Also, one has VTCs and one doesn't. The crank angle position sensor, MAFS, o2 sensor, power valve control solenoid valve, and AAC all have different signals along with a LOT of other little things that shouldn't effect major stuff.

Other than VTC, MAFS, o2 sensor, and CAS; the ignition system is most important. It's so different, I don't even see it possible to use a VG30E for software that was created for a VG30DE. I mean, one is DIS and one uses a distributor.

If i was you, I would look into some software that is made for the z31s. That might work.

 

Aaron, gotta question, Aren't the MAF's for the VG30E and the VE30DE the same? I was comparing Antons and mine and they had the same model number IIRC. I'm pretty sure they are identical. What do you think?

Sorry, I'm not a big 300zx guy, do they have DIS on the z32's?

The Power Valve has a different signal? I thought they just used the same basic solenoid?

 

The MAFS MIGHT be the same, but as far as the signal that the ECU needs are slightly different. But I have to use a z32 MAFS to get my stuff to work.

Yes the vg30de has a DIS. That motor is SO close to being a VE it's not even funny. What my question is, why didn't they just put a VG30DE in the 92-94 SE Maximas? Size issue?

Well, VG30DE doesn't have a power valve and the VG30E does. There are so many other things. Plus, the ECU is a completely different unit on how it operates. Have you ever done a self diagnosis on the VG Maxima and compared it to how the VE ECU does it?

 

VG Diagnostic, yeah, alittle on Antons. didnt get too involved with it though

Also the VG30DE is still has a timing belt right?

(if so thank god they used the VE... I probably would have broken mine by now (you too Aaron )

 

Yes, it has timing belt.

 

ahh, ok. i never really compared them much before so i had no clue. thanks for the info!

 

aaron, i want your MAF when you switch d00d

 

My stock VE MAFS? I wont' get rid of that, What happens if I want to change back someday?

BUT, I do have a spare MAFS sitting in a box in my garage. I got it from a guy that sold me his WSP CAI and was too lazy to remove the MAFS from it. So he threw it in for free. I'm sure it works. The screen has been removed though. And the other side screen is dented a little. But it should work fine. I can test it before I send it out.

Hit me up on AIM sometime and we'll talk.

 

Bryah, I have an extra OE MAF....

The VE and VG30DE are almost identical as far as operation, sensors, etc... the VE was designed as a smaller version of the VG30DE specifically to fit in the Maxima engine bay. it's about 4" narrower (across the heads) than the VG. otherwise, the only real difference as far as technology goes is the timing chain, intake manifold (w/ power valve), dual O2 sensors, and the fuel temp sensor..

Aaron, care to share any other differences that you've found yet?


As for the porting the TB that was talked about waaaay up there, I found a drum sanding kit at Home Depot that was about 3/4" smaller than the inside diameter on the VE throttle body.. it works perfect if you have a drill press. just set the press on high speed, put some gloves on and go to town. hold the TB by hand and move it around. not like trying to port a manifold that's too heavy to move yourself.

 

Basically, you mentioned all the major differences. The ones I'm mainly concerned about is o2 sensor and fuel temp sensor. I have the fuel temp sensor licked, but I am putting the o2 sensor off until I get my software. BTW, the eagle lands in a few more days!!!

Other little differences are, IACV-FICD, heated o2 sensor, PRVR, fuel pump voltage control, and some other little things like tach, speed sensor, and AC relay.... those shouldn't effect anything from what I can tell. Oh yeah, high speed cooling fans are not on the Non turbo z32. But i have a manual switch that still turns on the high speed fans, even with the z32 ECU. I will spill all my guts in a new thread sometime this coming week when I get my software hooked up and i make a few changes.

 

the reason i posted about the Ve maf is the pathy needs a bigger one.
kind of pointless to throw on a bigger tb when it can't suck in anymore air

 

But how do you plan to reprogram your ECU for the new MAFS voltage?
