Ok guys, Megasquirt is trying to move forward with it's technology recently.

They have come out with standalone boxes for more recent motors and they are showing A LOT of promise and affordability, which is a big plus for Maxima owners.

I've been talking with a dealer and well they are more than welcome to the idea of making PNP units for 4th gen Maximas, and in the future I will tackle 00-01 guys too.

I've already talked to a couple of 4th gen owners who I know could definitely benefit from this, but it's now time to go public and see who would be interested in going standalone w/ their VQ30 electronics.

This will be a very long process from initial 10 people to getting the box in your hand, I need 10 people interested and committed, then the box will be built, then I will have a test unit to work with before the final product is sent to you guys.

Before you post saying it can only do 4 coils/injectors, I already covered it with the dealer. I've seen this box being used first hand in a 8 second twin turbo fox body mustang (and no it wasn't a 4cyl).

READ THIS!

Looks like we HAVE to get MS a car, I tried hard keeping the setup process in Houston, but no luck.

I need someone who is willing to do without their Maxima for a month who is near Suwanee, GA.

-Looks like we found that person!

I've emailed the rep, now we play the waiting game.

-They replied, they want to see our ECU, I will be sending them a 95 GLE and a 99 SE-L MT ecu + a pigtail.

 

[edit]

Space reserved for cool pictars and stuff!

 

 

how much would this run?

 

I hinted at the idea at $500-$600 a unit, so far the dealer hasn't said anything about it being too low.

But I need interest first before I can even justify working with them on pricing.

 

This would rule over emanage units i assume?? Fully tuneable and have the ability.to turn on and off sensors as we need/wish for street or track??

 

Is this for 3.5 swaps or no?
I mean, will it have VTC?

 

VTC control would have me on the "in" list for sure!

 

just need more info and pricing... pnp as in just directly plug into the stock ecu harness as in specifically made for this car?!? that would be siiick! does it come with software and stuff? sorry i don't know much about stand alone systems

i dislike wiring diagrams, splicing and soldering and all electrical work in general lol

if it does everything EU does then i could forget about getting a bee*r for flames n launches, sell my vafc 2 and jwt ecu and just use this

 

That is the point, to make EU, VAFC and JWT or any other of those piggyback systems obsolete.

The only thing you'd loose is the function of your OBDII port like you would if you were going standalone, so if your state has inspections I'd definitely keep your stock ECU handy for a quick swap around inspection time, this is a complete replacement for your stock ECU, it will not be used at all for emissions functions. Not to fear for inspection time though, it's certainly nothing a quick ECU swap can't solve ... Unless you've deleted emissions equipment that need to be there anyways... Then that is of no fault of the MegaSquirt anyways..... And I'm talking in circles....

To my knowledge 3.0's do not have VTC function.

The unit has the ability to control it of course, but you would have to wire that in/tune it on your own.

 

This would be pretty sweet if this went through. I might have to sell my eu soon....

 

Man you guys are HARD CORE!! I'm just a humble 4th genner honored to be in your presence

DW

 

Does this mean you're interestedddd???????

It really isn't... PNP stuff is pretty cool and easy... best part it's cheap too! Something you rarely get in the 4th gen world... Cheap, Easy and Effective.

This is the Y-Pipe of electronic mods for your vehicle, why spend $500 on a JWT when you can just buy this??? Sure you don't get emissions functions but this is why you keep your stock ECU for "inspection" time if you need it. I know for me personally, inspections do not apply and I'm sure it's the same for others out there.

Honestly, if you have a 00VI and some other typical mods, it's be unwise NOT to have this.

Hxcore would be if we just got the kits and did the soldering and wiring ourselves... jesus christ

 

for sure.



----------------------------

anyway, from what i can tell, unused PWMs can be used for whatever since there's 8 and we'll only be using 6. so this is unconfirmed but, potentially, we could use those 2 for cvtc should the need arise.

 

Maybe this needs to be clarified.....3.0s dont have variable valve timing but they do have variable ignition timing. Does that clear things up?

DW

 

I don't think there is an issue on clarity, just that people want Variable Cam functionality to make their 3.5 swaps easier, while this unit is able to control a 3.5 (most of it anyways), I will not be offering any support for that function, simply because this will no longer make it PNP for 4th gens.

The point of this is to really offer support for 00VI'ers, Turbo Cars or Nitrous cars that still use the 3.0 and it's stock electronics, that have to use an army of devices to properly control their motor.

 

I would but a lot would have to happen for me even to make a commitment. I would need to rip out the EU and rewire all the splices. And running the stock ecu when there would be downtime is out of the question ATM. But if the cards played out correctly I would most certainly have a instrest for MS!

 

would this work for the 99 guys with transponders?

 

Yup! While using the standalone ECU you don't need to have a chipped key to start it.

Your security light will be on the whole time... So I'd just unplug it

 

I cant commit quite this early in the process but I am highly interested. and one more thing, you talked to those who could benefit and I dont have a pm about it.......what are you saying huh?

 

Y U NO HAZ SNIFFER SUPPORT!!! I want emissions control... they should really do something about that. I mean its just sending data out from the stock sensors... why couldnt you use the OBDII port?

 

Sniffer? you're fine if you're a 95 Maxima in Texas, use standalones all you want, as long as your car is tuned it'll pass......

If your state's test requires an OBDII scan.... Well you're fubared because standalones do not record emissions data.... to my knowledge, I will chat with the MS dealer again, but I'm pretty sure that Haltech/Emerald/Motec/Whatever doesn't have Emissions support because well... They are for offroad use only.... Just like Y-pipes and headers.....

 

I ran a PnP Megasquirt on my last project car, (1991 Escort GT, Mazda BP 1.8 w/ a Greddy 18G Turbo)

And I have to say the functionality of the unit was top notch. The tune ended up 100% perfect, and at 16psi made 296whp/312tq.. daily drove it 800+ miles per week without issues on the Megasquirt. All additional functions such as launch control and flat shifting also worked beautifully.

Megasquirt has definitely come a long way from the days when pple were scared of them. Its worth every penny.

 

A plug and play stand alone that can be easily swapped out for emissions... no wiring or splicing needed? This sound to good to be true, I am looking to go SC so if this is whats In the works then Im interested.

 

Thats the best part of the PnP.. Use the stock harness, swapping to stock ECU takes 5 mins

 

Thats awesome, and it has all the same features as say the Greddy Ultimate?

 

you called?

 

megasquirt is not for the faint of heart. Works great BUT only if you take the time to figure it out.

 

Wouldnt work for a true boosted setup. If your making decent boost you will be running bigger injectors which the MS can be tuned for, good luck just swapping out at will.

 

I'm trying to see where this goes...

 

I am definitely interested but unfortunately cannot commit at this time. The very second I can commit, you will be the first to know!

 

Heres a video of a rip in my escort on Megasquirt, you can hear the flat shifting on the 1-2 shift http://youtu.be/ce2qFH4ezbQ

 

My buddy runs MS2 on his built 2.0 A4 and I really like it.
Also, my boss has a Mustang Dyno and is unbelievable at tuning.

I'M IN, 100%!!!

 

Of course this means that there will have to be two different pinouts available, right? For the 95-98 and the 99 version... This sounds like a bunch of work for MS to map and use 3.0 sensors and controls for speed, temps, pressures, TC computers for autos, AC, dash instruments, and all the other support functions managed by the seven other computers on-board the car. Those schemes are different between some model years.

On the bright side, I could dump the NAT function..... I guess if I can tune the car for race conditions and swap back to the OEM ECU for whatever reason, I win.

 

Even more.

There isn't any figuring out to be done... After the initial run.... Just plug in and tune you'll have a stock Maxima base map.

If the car can start and run code free why not??

Good to hear!!

The ECU has nothing to do with most of that stuff... As I learned the hard way....

Now for the Automatic stuff, I am very unsure on, I have not had an auto maxima, we will need some one to chime in on this for the auto guys.....

Pinouts are the same from 95-98.... that darn 99 is where two pins get swapped, not that big of a deal there....

 

We're trying to have everything done in house in Houston but it's not looking to good, we will need a test car to be used for about a month in Suwanee, GA

 

[QUOTE=aackshun;85103 If the car can start and run code free why not??[/QUOTE]

You've obviously never tried to start a car running larger injectors then stock. Plus the vehicle would need to be driven for a while to get everything to a ready status. That in itself can take a while to do.

 

My 99 ECU kept it's ready status after the 6MT swap (2wk process, over a week of the ecu being unplugged) all of the emissions monitors were still good to go. This is how I found out that the ECU really only controls the motor and takes ques from other things (Auto A/C still worked and ran a diagnostic successfully, alarm still worked, starter still worked, etc).

Taping the MAF seems to work wonders for some one on larger inejctors... could be a quick simple solution?

 

I find that very hard to believe. I've swapped ecu's many times as well as simply unplugging it and its always reset the ecu. Heck, many simply disconnect their batteries for 10-15mins to reset theirs and your saying you can unplug yours for over a week and it doesn't reset?
