MS3X with 2jz-gte, not sure what to do next...

[kingtal0n]

Hello, I am now ready to begin cranking the engine for the first time, so I started setting up the ECU,

I went to firmware download page and received latest MS3 firmware first.
I Have MS3X ECU, but the software "detects" MS3 pro. I tried using "recommended" MS3pro firm ware but it gave me all kinds of errors and problems.
So then I tried regular MS3 firmware and I think this one works. Now the map is working when I blow into it, the tps is working too.

So where do I go from here? Is there a 2jz-gte startup file I need now? The computer still thinks the engine is 4-cylinder and has no trigger data or dwell data for 2jz yet.

pictures are coming soon

Are you sure you installed FW for MS3, and not MS3Pro? Post the MSQ.

OK, I re-read. It looks like you did install the wrong FW at first. So you are now getting ready again for a first start? Check the cranking spark timing, and post a log taken while doing that cranking check.

[kingtal0n]

This is just showing the result I had when trying to use MSpro firmware in what I guess is an MS3X box. The software "auto detected" the pro version which is how this happened. Just in case this happens to you (hopefully this thread will help diagnose other setups)

[billr]

I'm confused: have you loaded the standard MS3 FW, outside of TS? Are you saying the Pro FW now seems to be "stuck" in the ECU and cannot be over-written by the MS3 FW? That is what the error screen-shots indicate to me; that TS loads the posted MSQ and then gags when it thinks it finds a Pro when connecting.

[kingtal0n]

I loaded the MS3 firmware and it seems to have worked.

The ECU Doesn't know the engine is a 2jz-gte though. It wants trigger data, dwell data, that sort of thing. I am not sure if there is a base calibration map or if I need to pull the trigger out of the engine and count the teeth. The last time I played with a Megasquirt 2, I had to soldier some things to the board to get the ignition outputs to work, and find a trigger wheel to give me the 60-2 configuration, and somebody explained how the coil worked which was really nice. I learned alot from the forum, thanks in advance.

[billr]

The screen-shots above are no longer pertinent? Is there a new MSQ that should be posted?

Why do you think MS is treating this as a 4-cyl engine? You do know you have the "number of injectors" set to 4?

I think the spark mode setting "2JZ VVTI" only defines the crank/cam trigger patterns, it does not set the coil selection or parameters. I don't see where the trigger angle was asked for in the posted MSQ; that's why I asked if there is a new one.

How about the coils, are those true COP, or wasted-spark with the coil on one plug and connected to its partner via a short HV plug wire?

Thanks for helping,
1. It is true coil on plug engine
2. I do not know the trigger angle or coil selection parameters for this non-vvti 2jz-gte engine
3. There is no msq update because I am not sure what to do next

I assume injectors = 4 is factory setting. I don't want to start playing with any single setting until I can have knowledge of all of them, and I will do it all at once. This way I never wonder "hmm did I change this already?" I wish to identify every single input before changing anything.

From what I gather you basically just told me all I need is coil and coil parameter, trigger angle and to select 2jz-gte VVTI for the trigger and that would get it started I think.

[billr]

Set it for 6 injectors, if that is what you have.

Can someone confirm if this is a megasquirt MS3X or MS3? I am still not sure what it is exactly.

I read that ms3 should be easy to setup for 2jz-gte but so far I dont see much online about configuring it yet.

That's an MS3 V3.57 with MS3X. Pre-VVTi 2JZs are a standard Nippondenso CAS ignition: http://www.msextra.com/doc/pdf/html/MS3 ... 4-147.html

thanks,

SO its a 12 tooth wheel but we say 24 because it goes around twice.
And I will need only 1 cam angle sensor which is a single tooth.

So now the trigger angle... there is no mark on the balancer so I will have to find somewhere who has the OEM angle I think? , shouldn't be hard since this is like the most common engine in the world lol

[Matt Cramer]

You can set the tune to 12 teeth at crank speed or 24 teeth at cam speed, although from the ECU's perspective these will look the same, as you expected.

If you have no timing marks, you can find TDC with a piston stop and paint marks on the balacner.

Okay, you are saying to get the engine started using a close guess angle, then dial it in with a light after putting a mark on the balancer.

I would do this if necessary; I only thought that there were some OEM setting they all used to avoid this procedure.

[billr]

Don't try to start it with that "first guess", disable fuel/spark until you use the light to verify timing is OK. If it isn't, then just a few iterations of adjusting the angle in TS will correct it. You should be adding timing marks and using a light to verify timing no matter what, even if you do find a published angle value, so using the procedure is little extra effort.

[kingtal0n]

Okay thanks, yes of course would be necessary to verify the timing before any driving, I only thought this engine was so old that the angle to get it started at least would be highly available.
Usually when I look on the internet for something and don't see it, that means its really really simple and nobody bothers to even post it. Which makes me think the angle is 0* or something really obvious. hahaha

I found this post,

The crank has a 12 tooth evenly spaced wheel and there are two separate (G1 and G2) cam signals triggered off a notch in the cam (none of which are adjustable). G1 triggers when piston 6 is at TDC and G2 triggers when piston 1 is at TDC. On MS2 extra I run off NE and G2 with the tooth offset angle set at 0 and the car runs great.

I have no idea what to set the Trigger A, B C and their returns to for this though...same with the trigger angle. Any advice?

And I do not understand what they mean "returns A, B, C". Is that a wastespark thing?

In my case would it work if I set trigger angle to 0* as he is suggesting and use the rear cam sensor? I should be in sequential.

Hi, I'm specialised with 1jz/2jz Megasquirt.

I finally had a chance and went through the settings one at a time and changed them.

This is the main page I am stuck on. There are around 8 subtle setting I am unsure of.

Here is my new MSQ File as well so you can see I really went through it up until this page.
I think ignition input capture is the cam sensor, and I am aware of the issue with the cam crossing the crank (I think it was those two) and that there was one config that worked best. I don't mind experimentation there and I don't see the harm. The rest however, I can't see myself doing much experimentation to find those numbers.

:2jz-gte from around 1998
It has stock coils
1 coil per cylinder
Toyota produced these coils in like 1998~ era

They used -6 on the rear cam sensor here:

[kingtal0n]

So now I think I've got the computer ready. I think the next thing is to adjust these dials on the board.

I see R11, hysteresis, R56 and R54

Turn them all counter clockwise 10 times~ or until stop or click, to get signal from crank trigger?

hey thanks brother, yeah I have no clue what I am doing unless you jump in here and say somethin!
