2JZ VVTi

[joooeone]

i got the composite log and i found the problem we had was jumper conected on the megasquirt expansion "JP7 INPUT PULLUP JUMPER".

i got a a couple of question i dont know how to hook up the camsensor on the wiring diagram it shows that you got to conect it to main ground plug DB37
http://www.msextra.com/doc/ms3/hardware ... iring-ms3x

so that means that i got to hook it up to the pin 14,15,16,17,18,19? the one that says good engine ground or the pin number 7 the one that goes to the tps wide band mat coolant sensor?

and another thing i did the injector test and it did work but i try to do the coil test and had no luck so i was wondering do i have to conect the oem igniter? or probably the coils are not conected like they should,its a 2 wire coil and using the ms3x for the coil spk a spk b and spk c

The cam sensor negative needs to connect to signal return / sensor ground on the main DB37 plug. Any spare ground will be ok except the engine grounds.

As per the manual, the MS3X spark outputs are low current logic outputs and cannot directly drive a high current coil. A 2 wire COP will be a high current coil that needs an external ignitor. If you have the stock ignitor then use that. It will almost certainly take a 0-5V input signal and require "going high (inverted)"

yes I do actually got the oem igniter but I don't know.how to connect it let me show you.a picture

[joooeone]

this is for a 2jzge vvti but is kinda simillar to the one that I got

[jsmcortina]

Looks easy enough.

James

[joooeone]

do you know what igf means?

[joooeone]

and what about tach it should be a tach signal from the megasquirt?

[Mhm]

It looks like that coil driver box is already sending a tach signal to your car.

I'll use it as is and only have the MS trigger the coil driver box.

[jsmcortina]

Agreed.

Ignore IGF, it is feedback to the ECU. Megasquirt doesn't use that.

James

[joooeone]

alright I am I gonna use coil 1,2,3 as outputs.for.the actualcoil t 1,2,3 is the inputs for the mega squirt B+ is voltage in to the ignitor and ground that s it ignore igf and tach rigth?

[chango de naranjito]

IGF is ignition feedback to the stock ecm you need to groud that pin if you need any diagram let me know (I'm a Toyota certified technitian) and have acces to all that info

[joooeone]

chango de naranjito si seria buena idea q me ayudaras con esto gracias
nos comunicamos en PMs?

Yes

[joooeone]

well i got the engine runing now but one more question on my injectors y got my injector hook up like this a b c d e f but the cylinder timing is 1 5 3 6 2 4 so the injector should be hook up like this, a e c f b d? or just linving like i got the hook up?

[Mhm]

MS will fire injectors in sequence a-f, so you need to wire a-f outputs then ccording to your firing order.

[joooeone]

so a,e,c, f, b, d is the way to go rigth?

[jsmcortina]

Please read the manual:

or to clarify....
for the Sequential Ignition I6 guys out there...

Coil A -> Cyl 1
Coil B -> Cyl 5
Coil C -> Cyl 3
Coil D -> Cyl 6
Coil E -> Cyl 2
Coil F -> Cyl 4

Always Fires A-B-C-D-E-F... No other way.. Sorry....

James Correct me if I am wrong... But I am Sure this is Right... Been like this Since MS1-extra...

Cheers.. (My 2cents worth ;-))

[joooeone]

what i got it like a.e.c.f.d.b

[racingmini_mtl]

what i got it like a.e.c.f.d.b

If you mean this:

Coil A -> Cyl 1
Coil B -> Cyl 5
Coil C -> Cyl 3
Coil D -> Cyl 6
Coil E -> Cyl 2
Coil F -> Cyl 4

Then that's correct.
