I went this way bc i want to start whit something simple . it was my first big project and i dont wanna get lost.
but like rmh3093 says cop , and cop sequential is possible whit ms1, its possible in ms2 at the time but in wastespark only.
--------------------------------------------
there is a lot of devlopement at this time ..GPIO General Purpose Input/Output Board
Inputs
5 general purpose inputs [GPIx], which can have voltage or resistance input, depending on build-time options (based on the V3 sensor input circuits), these can also be used for software debounced on/off switches,
4 VR inputs [VRx] (based on Bruce's EasyVR schematic), for things like transmission controller, vehicle speed indications, or traction control,
4 EGT circuits [EGTx] (using AD595 chips), for independent exhaust gas temperature measurements. (These can also be configured for resistance or voltage measurements, similar to the GPIx circuits)
Outputs
4 general purpose outputs [GPOx] (which have user selected 5V or 12V pull-ups, flyback, and LED capabilities),
4 PWM outputs [PWMx] (based on the uprated V3 PWM FIdle TIP120 circuit),
4 high current circuits [VBx], using the VB921 ignition module driver
thats enough to do sequention cop , cam sensor , Even vtc pwm
--------------------------------------------------------
There is also a good thread on ms extra forums concerning cop on RB engine and nissan CAS
http://www.msextra.com/viewtopic.php?t=25379
And heres a good nissan Vtc speculation thread
http://www.msefi.com/viewtopic.php?t=20701
rmh3093.. actually i was quite impress how my car run ,at first i got it running but it was really bucky and pretty hard to drive. Then i meet someone who help me a lot ,the drivability is almost near stock , but pretty pretty much more agressif .
its still kind of a little bucky when warming up , but once it done it run pretty well. I had to get used to my act clutch too. i need to work on ,my accel , and a few other thing ,
I think i switch to ms extra soon ... and see how it goes , and try some goddies.
NmexMAX is this graph running at WOT ?
This should help too, from another thread
So I might be getting their top of the line EMS with 2 step, so any info would help.

Also, there are many DIY electronic projects that dont fall into any category... like the homemade o2 simulator and dual-stage shock sensor, etc... just my 2cents...

rmh3093
inj per engine cycle 2 .. could be 6
inj stag = alternating
Dont forget ms is a little experimental plus, you could lost things like cruise control etc..
I am not one of thoses who dont want to share maps or tips.
i you or anyone else have question feel free to ask , ill try to answser it as far as i know , and if i dont know ill tell you .
id like to see someone run stock cas and cam sens, cop

that wont be a problem... is there anything else you know that I will be loosing?from what I can pull out of the ms forums the router board might be ready for christmas time, i really dont want to buy an edis6 setup and then months later have to buy the router board.... maybe i will just set it up for fuel and sensors right now... that way i can take advantage of the +.5bar fuel for timing mod and BBMAF mod
... i will still have to read up about all this wasted spark stuff is all about

i dont know what other troubles , maybe climatic control , abs , automatic tranny.. i dont know
depend if it take signal from the ecu , you can check whit shema in the fsm
Ms can read MAF but i dont know more than that ... i use map

I think i just found a way to do COP wasted spark without EDIS:

yhea thats kind of odd , why cant u just use output and put Vb921 just like ms1e guys do.
I am curious about the real , physic ou software reason.
anways if i were you ill wait on the router or gpio , anyways a ms1 chips aint expensive
or you could run wastespark until the router is release
ill fallow your post

....what kind of cam and crank sensors do we have on the VQ?
08-21-2007, 08:21 AM

I am not sure , but i pretty sure members can answer
All i know is one of the crank sensor is on the ring gear/flywheel and its a 360 theets now that way more theets than the procesor can andle , i think we will have to fill some of thoses ***** whit epoxy
as for the cam i am not sure i guess we can find out by looking at the cam itself i think there is only one hole
no need for the edis , for either of those application , i dont even know if it will work, its been designed to drive ford coilpack+standart wire not cops

I'm helping a buddy wire up the MS to his VR6. My first so I'm going to do definantly follow up on this thread.

here some helpful info to keep with this thread:
does this mean we dont need to buy/use those VB921's since our OEM coilpacks have power transistors already in them?
This Nissan's engine is equipped with a distributorless ignition system (DIS), with a separate power transistor mounted with each one of the six coils. This gives each cylinder one coil and one power transistor. A separate signal from the powertrain control module (PCM) to the base of each of the power transistors turns the power transistors on and off. The power transistors pulse coil negative to ground, based on those signals from the computer.

According to this we can do 6spark COP sequential with ms1/e:

hightuner, you already mention you dont have emissions tests where you are and I also believe you are running the MS2 in full standalone ecu mode correct? what exactly are the laws about running a stand alone in the US, cause im sure ODB-II wont be working with the MS, i dont know what happens with the service engine light (but i guess if that never comes on that always good for passing inspections)... are the emmisions monitors on the CAN bus in our car? cause if so then it would seem like it dosent matter if im running a standalone ecu or not, it could still get inspected in the US/NY.

Sup pal ,
I do run ms2 as a standalone. and as you said there is no emission test here , well at least for now .
-------------
EDIT: one good thing i mention above dont know if you catch it ... one good think you could do is make a conversion harness , that use the stock engine harness and convert it to ms , that way you could switch to oem ecu in seconds .. if i had to do it again i guess id spend time doing this , could also be good if you sell the car later on...
------------------
I do not have any check engine whatsover , i just plug tach , speedo .never had to play whit the gaz since its not in the ecu harness . its plug directly to the tank sensor
i know a lot of guys on msefi live in the state so i guess it should not be a problem. did you try a search on the forums
I dont know how it work in the us , i live in canada qc .
I guess the reall question is , do they connect to the ecu , how just analyse the exhaust gaz. Did you ever pass one ?
So did you decide whitch way your going , ms1 , ms2 ...
EDIT: btw good job whit your post over msefi , i had a doubt it was a wirdo reason that we could use the ms2 to do a 6cyl cop seq. kind of sad tough ...

Do your power windows and AC work if you have them? Also, does your abs work, security alarm?
I think im still leaning towards the MS1, megatunix is written for gtk with glade which i've used and I know enough c/c++ that I can tweak the megatunix UI to fit perfectly on my car computer touchscreen... plus the software does support 6 spark outputs if I want to go that route...
...i haven't decided anything yet though cause im still trying to figure out how to set up everthing... I still dont know crap about the VQ30DE's cam or crank sensors or how many tooth wheels we have
i also have to find out more about our injectors cause we might be able to hook them right into the megasquirt, but im not sure
