Fact:
95-03 Nissan ECU's are the worst ecus in the world for tuning ?!!!!!!!!??

 

*I haven't checked in/read the thread, I'm just opening my mouth*

On the phone w/ my dealer right now.

They stopped working on it because of the Cam sensor problem, MS2 does not like fancy smancy cam signals (I knew this from the beginning from talking with MS2 owners), we looked at having cam plates made (won't work for 99% of maxima owners which are generally lazy), looked at custom crank pulleys being made (won't work for 99% maxima owners because we're generally cheap), but even if we had a sensor made for MS2.... we'd still have one big problem.....which was Batch firing injectors (why downgrade bro? )

Why stop working on it? Elementary Watson... PNP MS3 units are about to be released so all of the aforementioned problems no longer exist and the unit will truly be plug and play like I discussed in the OP.

Only problem we have now are the delays, but once MS3 comes out they will take an AUTOMATIC 4th gen in for testing, if they can get the auto to work then the manual is just a couple of settings here and there away before turning your ignition.

I'll be checking back in to update the list, if those of you who were in for August/September completion date only have to back out, let me know, we're now looking at November before a car gets called in.

And thennn.... They liked the idea of having a supply for plugs, that was another problem but now has been solved my Darren @ Voltage Drop....


Annnd back to ghustling for me

 

Update!

Ok so some of you probably wondered where the hell have the updates been, got a good one today.

The megasquirt 3 is the board/hardware we are using but megasquirt will be making custom boards for our cars only, so that will enlongate our process from car drop off to megasquirt drive away, but this ensures total 100% functionality and compatibility.

I am awaiting a call back from the dealer on an exact ready date but as of now, the first week after thanksgiving will be the week MS will take a stock fully functional auto 4th gen.

The development time will be 6-10 weeks once the car is ready, any volunteers??

 

This is true, if you are keen on the idea of flooding your cylinders go for it. Still a great idea for non boosted 3.0s with stock injectors, keep up the swag aakshun.

 

Cool beans?

 

Aaron, I'm still interested - this would be great to have. Do you suppose they would take my car for the development mule? Probably not...

 

Are we still on track for car submission after Turkey Day? Who's the donor?

 

Ok, we still need a volunteer, preferably auto. The idea is if you can do auto, you can do anything. This is so we don't leave anybody out in the cold.

For the sake of the project, we're going to put 2 week time limit on an auto guy to step forward. If we can't get anybody by December 17th we will go ahead with testing using a manual Maxima.

 

Interested to see where this goes. But sadly the '95 ~ '01 Cam sensor is one of the worst signals to process. There are some work arounds which is possible with a piggyback and OEM ECU. I was modding the signal off the crank pulley with the SMT-6 enough to trick the ECU into advancing timing a couple of degress when in open loop. But I don't see this working for a true plug and play unless people switch the cam sensor trigger wheel out for something less assinine. There are a few high end stand alones that can process just about any odd cam signal you throw at them, but you are looking at $5K or more for those stand alones plus the wiring harnesses and other crap.

 

Well now. I live in GA, drive an auto 96SE, and can make it to Suwanee to personally drop it off. Problem is that it is my only car and I don't have a way to get around or to get to work for a month without it. And I just realized that post was completely useless but I am at work and can only post briefly.

 

 

Don't think you've been reading, they are MAKING a board for MAXIMAS only because of our Cam Pos.

 

 

Hating? Not really, just being realistic.

But do you believe for 10 ~ 15 ECUs they are going to design a whole new board? What is the projected price of these ECUs? I can name several ECU tuning companies that showed interest and then gave up. If its anything like the last 10 years I've seen with these tuning companies they will just drag you along and then complain the signals are to complex and not worth pursuing for a Maxima. But they will roll out the red freaking carpet for just about any other car out there.

Not to mention a 16 x 16 fuel and timing maps with batch fired injectors is a downgrade even for the stock ECU. Hopefully if this does happen they will have better tuning resolution and sequential injection for this new board.

 

where in GA Aack?

 

Ive got to agree with you.




Untill this is actually made and for sale for a decent price, we all know the chances are low of this ever happening.

Not only is this a Maxima but its a OLD Maxima at that.



I offer a PNP EMU harness for 4th gens, that's about the best thing going for 4th gen tuning right now.

 

And the main reason the 2002 and up Maximas have the Haltech, UTEC, etc. was due to a trickle down effect from the 350Z aftermarket and that Nissan used similar ECUs for both platforms. Same goes for VQ35DE internals, plenty are available off the shelf. But very few companies make off the shelf VQ30DE internals, as it was a Maxima only engine.

 

True, then again I also do the PNP Haltech and UTEC harnesses! No big companies are supporting Maxima's in the tuning field. Other the Uprev with 04+


Haltech COULD have made the same harness I'm making for 5.5 gens but they knew the market was next to none so they didn't bother! Same with UTEC they COULD of put the grey connectors on that unit.


I'm borderline crazy to even be doing what Im doing with all these harnesses!

 

Don't feel alone in your craziness, I was looking at the Pectel SQ6M standalones for a VQ30 application...

 

Savannah.

But you'll say goodbye to your car for 6-12weeks though.....

Are you even following the company at all? Or just talking based on your limited maxima.org window?? Which is what it seems like to me, there is a very big reason why I'm no longer what I consider "active" on this forum anymore, a lot of it has to do w/ the general mentality of users here.

Batch fired injectors on v3? I don't think so.

Cost? I really can't say what our cost is going to be.

I do know based on previous boards that have been manufactured $550 would be on the high side, then again to my knowledge of their current projects the VQ30 would put it on the most technologically advanced motor thus far

The LS ain't that complicated to get running, I'm not sure if they finished a board for those or not.....

BTW, seen many 8 second cars use Meqasuirt's V2 board, quite sure the V3 will be more than enough to get our cars the performance we want out of them.

 

EMU FTW!

 

if i ever get around to getting rid of the vafc2 for something better (either this or emu) then i'm hitting you up for that harness for emu... i ****ing hate wiring, always afraid of cutting something or connecting something wrong. thank goodness there's a bunch of mechanical stuff left in the car for me to play with

 

Dude EMU sucks azz.

Everyone in here whos swinging off the GReddy ******* needs to quit, how the fck can you tune a car properly off of a piggyback from 7 years ago?

I have it in my car, it was 'cool' for awhile but 16x16 isn't enough resolution and rev limit is awful. And you are tuning your car just by manipulating signals that the stock ECU gives you, which can change (longterm fueltrim/short term fueltrim wise).

 

Should've stuck with my VAFC2... But seriously it's not like we had many options.

 

I for one think that everyone should put aside their differences about which outdated and inadequate EMS is better and get behind and support THIS ongoing project with MS3. Let's let the engineers and programmers know that we support their ongoing efforts and lets get this thing built and working correctly.

Talking a bout a piggyback 7 years old when vq30 is more then 10 yrs old. lol


Anyone willing to put serious money in a maxima should just go ahead and do 3.5 timing and run a real ems system anyway.

 

WHERE THE HELL DID YOU GET THIS??? i almost fell off the bed lolling at this. so... fotblol? haha

 

Anyone know what the status is on this? I'm quite interested. Using this instead of my EMU would be very good...

 

 

I am 100% in to buy the finished product!

 

actually, they're building us a special board to accommodate our plug, hence plug'n'play. the ms3 hardware can already handle sequential fuel injection and ignition. sensor recognition and decoding will all be down to the software. it doesn't take 6-12 weeks to redesign a printed board, working out code to support our asinine cam signal, as you put it, could.

 

 

Fixed.

* There are a small exception of members here but this is about 96% true.


We need a auto car to goto Savannah, GA.

If we don't get one in a week and some change, we're sending the Manual guy who's willing to go and most likely loose out on all Auto support.

BTW there is a test car in houston.... But we don't have le funds to drive to houston and get back on our own dime.

Honestly I'd rather ship the car for $550, it'd be easier and about the same cost.... Problem is I don't have $550 lyin around.....

lawl if I had 550 burning a hole in my pocket the RED car would be running

 

I mentioned the crank/cam stuff earlier as well. Our SMT6 project was NUTS!!!!!! This is a step above that.


Eitherway, good luck.

 

AACKSHUN pm me your number we need to talk I can get MS a 99 auto Max by monday.

 

Don't know if these will be needed, but I have all eighteen of DandyMax's 3.0 cam and crank timing graphs in Photobucket.

Here's a sample or two:





Anybody need these?

 

im SURE they can use those

i had those saved on my desktop back home

 

good stuff

 

Damn.. you guys still workin on this huh... good to know... my 00vi setup is being cleaned as we speak and sometime by spring itll be on with all new gaskets

 

Ahhh those bring back memories and Perfect Power said the SMT-6 wouldn't advance timing on the Maxima.

I might be pessimistic with this MS3 box, but it would be great if this works out in the end. I think it would fill a price & performance gap between the EMU and Haltech. SAFC/VAFC - JWT - EMU - MS3? - Haltech - AEM EMS - Motec/Pectel.
