not yet but its very close , need to take care of a water pump leak and had to run over to napa for a fitting to take care of a small fuel leak on the fpr

im heading back to the shop in about 30 mins

heres the downpipe routing ( side front exit ftw )


and some of the wiring ive been working on

project89

iTrader: (1)

id be lying if i said i wasnt nervous about hitting the start button , if i wasnt nervous id would have been running already , ive been double and triple checking everything

if i dont fire it tonight i will be firing it in the morning

Street Lethal

iTrader: (16)

Just make sure the little things are done; brake booster vacuum line, PCV vacuum line, base timing is set right, oil lines to and from the turbo all secure, etc. I like that exhaust exit, reminiscent of Steve Kaminski's old TTA...

no/intermitant spark , was getting late , and was pissed off i got a flat on the bike , so i called it a night , ill have it sorted in the morning


shes starting to look mean , now i just need to adjust the intercooler mounting brackets and get some smopked or dead clear parking light lenses , im prolly going to do smoked with blackout tailight and headlight covers

She is coming along nicely. I am thinking it will trap mph for 10s. You think it is the reluctor wheel rusted in the the dizzy giving bad triggers or a wiring problem?

I would be careful in terms of turning it over and not starting quick fearing loss of cam lobe(s) with the big springs you have in it. Disconnect injectors, pull the dizzy and spin by hand and watch plugs to make sure you can get it to fire the plugs properly. Put a ground wire on the dizzy when it is out.

Flats on bikes suck. Depending on the app, I will plug the tire. Yeah, I know.

project89

iTrader: (1)

this one i got at a low speed , my last flat was cause my wheel didnt have a beadlock and i was in the dirt doing about 60 and came up on the asphalt , the tire was spinning when i hit the road and it ripped the valve stem right out of the tube giving me an instant flat at speed , damn near sent me head on into oncoming traffic

yup was worried about turning it over without getting it to fire so i just left it for the night till i could think about the issue and correct it , the timing sounds super late when it does fire , need to double check the ground on the module as well

i may also have it set incorrectly in my tune to inverted spark signal which will cause the same issue , im pretty sure this is the issue as i loaded an old tune in the ecm , which used different ignition settings if im not mistaken

and yes i did check to make sure its not 180* out

ill be heading to the shop at 5am , speaking of which its midnight i should be in bed lol

Street Lethal

She definitely is, but I do see why you want to lower it in the front...

You running MS2 extra?

Went back and forth with another member for a week or two, all to find out the wiring was wrong (had a wire in the wrong pin).

https://www.thirdgen.org/forums/dfi-...rt-91-tpi.html

I swapped mine over to DIS so I wouldn't have any coil dwell issues. Not that I rev very high anyway, but at least I'm guaranteed the same hot spark every time.

The vortec dizzy coil/module pair will give full spark mJ up to about 6500 rpm. What DIS system you running? I don't like the Ford EDIS in stock form as you can't rev limit it.

Project89,
Awesome job. What was the spark problem in the end?

project89

iTrader: (1)

had a setting backwards in the tune , i went back today to grab a video and found a small puddle under the car , water pump shaft is leaking so i didnt even mess with it as i cant get a water pump till tommorow, and it about to storm pretty bad here so i just came home .

ill try to get the waterpump fixed and some vids tommorow though i still have alot to do to get it race ready

Haha, they don't know you the way I do Dave lol. Believe me when I tell you, if the videos weren't posted, not to mention the other stuff that people here seem to be complaining about, Dave would never have gotten this far. He needs a push, and it seemed to have worked, as he got a lot done in a short amount of time. This isn't a tech thread though, it's his personal build that he is sharing with us, and he can pretty much do whatever he wants in it, within the rules of course. Just enjoy the ride, as that is all it is, life is too short to be complaining about this crap, and like he said, if you don't like it, you don't have to be apart of it. Tech can always be found in the stickies where they belong, the non-sticky stuff consists of new members asking questions, and regular members sharing their builds the way they are building them. What really pisses me off about this board though is the lack of comradery. When I am on the Turbo Buick boards you rarely see these arguments, the SFI-6, FAST-XFI and SD2 guys help each other if they can, they back each other, and they shoot the crap in the lounge area to have fun. Everyone here argues about which system is better, they criticize, make derogatory remarks about other members rides for no reason at all. If anything, that beahvior is what brings the quality of the website down, not the way an individual chooses to update his build threads. Meh, but it is what it is...

Since Project brought this up in his own thread, imma leave it here in the interest of improving this place like my complain thread was intended to do. If you really want to continue, projects thread on the bullet would be a better place

Street Lethal

iTrader: (16)

How can you question that? After reading what was written to JT by you, clearly you have a problem with this thread, or even mine, for your own personal reasons. Whether not being done fast enough, or to your own personal liking, is irrelevant because they aren't your threads. The very fact that you are here embellishing your point underlines what I said, not to mention you were also told by the very authority you reached out to to take it to PM, but you choose to make a spectacle out of it in a thread that doesn't belong to you, so not quite sure why you could possibly respond with "what" lol. Incidently, asking for a new or additional mod is a slap in the face to Joe, the guy has been through enough this year...

On the bullet esse!

anesthes

iTrader: (12)

That's good to know. I struggled finding a HEI coil with reasonable dwell.

I'm running EDIS right now, and yes, since it uses a controller you cannot command it to drop spark. I may switch to LS2 coils next year as I can control them directly with my ECU.

Congrats on the build, it's looks great!

As far as videos and such in threads, I don't mind a little straying from time to time as it keeps the thread going. The thread is mostly tech, and valuable for anyone constructing their own builds.

ugh napa needs to open earlier i shoulda just went to the shop when i got up this am and then ran back into town to pick up a new water pump

i could have atleast swapped the vb gaskets inthe trans , and or made my tq arm front mount int he time ive been waiting

besdies that stuff i need to fab a couple brackets for misc things , make the oil feed and return lines for the turbo and bolt that back on and i need to runt he shifter cable for the trans.

other then that is all cosmetic stuff which i dont need to do before the race

project89

iTrader: (1)

joe i need ya on this one .

fixed the water pump, went to start the car and the injectors are hanging wide open soon as i power up the megasquirt

last time i had the injector power and megasquirt power seperate and that was my issue

this time both the ms and the injectors are wired to relay #2 on my arc 4000d switchpanel so they both power up at the same time

what do i need to check internal on the ecm ? that would cause this issue

Street Lethal

iTrader: (16)

Are you still getting fuel pressure with the injectors stuck open?

project89

iTrader: (1)

yes pumps can move more fuel then the injectors can dump wide open
only thing i can think of is the battery was a lil low so maybe the ms was powering off when cranking . before i left the shop i threw the battery on the 40 amp charger , when i go back ill put the battery back in and hook it to the charger and set it on 200 amp car start to make sure the voltage doesnt drop when cranking

Street Lethal

iTrader: (16)

If not the battery, I was just scrolling through some similar situations associated with injectors that are stuck wide open in the Megasquirt world, and it sounds like you may have inadvertently blew the FET pins or driver if it turns out not to be the battery...

anesthes

iTrader: (12)

Key on, engine not running, the injector wire from the MS should be open (i.e not grounded). If you have a ground than it's a wiring problem.

The problem you had before was the injector wire being grounded key off which is a defect in MS2 controllers due to the injector driver they use.

On the + side of the injectors it should be wired to a circuit that is hot in RUN and CRANK.


-- Joe

project89

iTrader: (1)

+ side of injectors is wired to my arc panel as is the power to the ms
so when i flip that switch on both the ms and injector recive power

will head back now and check the ms grounds for the injectors and see if they are open or not when power is applied

Orr89RocZ

iTrader: (20)

How did you do it before when it ran on old motor? Is this a different system?

Street Lethal

iTrader: (16)

Think the arc panel is something he recently added...

anesthes

iTrader: (12)

Yep, the ECM is a pulsed ground to fire the injectors. Power is constant to your fuse panel.

Again, if you have a constant ground while in the "run" position, either your wiring is shorted to ground or your MS2 is junk.

-- Joe

project89

iTrader: (1)

yes the arc panel is something new


just disconnected my injectors were they plug into the main harness powered up the ecm and put a test light on the + side of the battery when I probe the injector wires the test light is lighting up , so its staying grounded and holding my injectors open




going to check all my pins and make sure I don't have something screwed up on the wiring


need to lookup how to test the injector drivers


whish my friend was intown id just borrow his ecm and see if it did the same thing

project89

iTrader: (1)

joe im on super slow internet atm can u tell me which pins are the injector grounds I wanna reprobe the pins with the megasquirt powered up but I wanna probe them directly at the ecm to see if its an ecm or wiring harness issue

project89

iTrader: (1)

joe never mind its in the ecm for sure , hooked testlight to 12v+ and probed the injector wires on the harness side


its an open circuit so the issue deffinatly lies within the ecm


im thinking I burnt up the drivers when I inadvertently loaded an old tune that used high z injectors , and didn't have the proper injector settings for my low z peak and hold


going to call up my local radio shack ( 60 miles away) snd see if they have the parts needed to rebuild the injector drivers


if so I will continue to assemble the car and pick up the parts on my way to the race track and fix it there , im also going to ask my friend if I can borrow his ms2 , hes the one whos towning my car for me to the track

Assuming a 3.0 main board

32 INJ1 Blue Out Injector bank 1 output 7A
33 INJ1 Blue Out Injector bank 1 output 7A
34 INJ2 Green Out Injector bank 2 output 7A
35 INJ2 Green Out Injector bank 2 output 7A

Use the other driver. You've got at least 2, possibly 4 depending on which rev you have.

Set it to fire batch.

To run low-z injectors you need to add a resistor pack.


-- Joe

project89

iTrader: (1)

ye I was able to peak inside the db connectpor and see which pins


the ecm is not opening the ground circuit when I power it on
is there anything simple I can check in the ecm without just ordering all the parts for the injector drivers


ive got a basic multimeter and testlight at my disposale atm anything more then that and ill need to run home

Street Lethal

iTrader: (16)

From Megasquirt Support...;

Check mosfets Q1 and Q5 by measuring voltage on their gates. you should not observe any voltage when injectors should be closed. if there is no voltage (up to 0.2 volts treat as no voltage) but injectors are open and there is no problems with wiring your mosfets are gone.. if there is voltage (typically Vbat ) check mosfet driver - U4

to do this measure voltage on pins 2 and 4. there shoud be 5 volts when injectors are closed (because of inversion) if there is no voltage(i mean 0-0.2V) switch off power and remove ms cpu/ms2 daughter card , switch power on and do measurements again. if there is still no voltage on pins 2 and 4 check R 14 and R17 pullup resistors. if there is voltage on on pins 2 and 4 and there is voltage on mosfet gate U4 is gone...

That article may help. I believe you blew the fet.

If you use Lowz injectors you need to add resistors. I believe Nissan has a factory inline resistor for such usage found in the junkyards. Othewise, Jperf makes an adapter board.
