Question on Daihatsu VVT (EF-VE 3Cyl. 660cc)

[francia]

I'll swap the Daihatsu engine EF-SE (NA 3Cyl. 660cc OHC 6valves) to EF-VE(DOHC 12valves VVT NA)+EF-DET(DOHC 12valves Turbo) next weekend.
EF-VE has two trigger wheels for VVT.
Engine timing : 3+1 tooth trigger wheel on cam
Cam angle : 3 tooth wheel on cam

Can I use VVT using spark mode "Daihatsu 3Cyl" no modify ?

Not currently. Are the three teeth evenly spaced?

>Are the three teeth evenly spaced?

I never check 3 tooth of cam in my eye yet.
EF-VE VVT engine will be arrived my yard next Saturday.
I'll report angles of 3 tooth asap.

I'm looking for the article of Daihatsu VVT, but correct angles of 3 tooth not be wrriten.
If angles are 120degree each, MS3 pre-1.4 alpha farmware can control Daihatsu VVT ?

[jsmcortina]

Not yet, as the code does not allow VVT with the Daihatsu wheel mode.

With an evenly spaced cam wheel, the standard VVT code should work once it is allowed.

James

Today I check 3 tooth wheel on cam, its 3tooth have even space (angle 120 degree = 360/3)

Relationship of signals (3+1 main trigger wheels and 3 VVT wheel) is never known, not described in the Daihatsu documentation.
So I'll check it after VVT engine installed the car.

>With an evenly spaced cam wheel, the standard VVT code should work once it is allowed.

Can the standard VVT code control Daihatsu 3Cyl. VVT ?

[jsmcortina]

For the next alpha, I've made it so that it _ought_ to work, but haven't tested it.

James

[francia]

I'll do test next alpha gladly.

[francia]

I built Daihatsu engine with turbo and VVT, and installed it in the car.
But MS3 pre-1.3.3 beta 5 and MS3 pre-1.4 alpha 6 do not arrow to use VVT on Daihatsu 3cyl ignition mode(3+1 triiger wheel).
And CAM signal of VVT was not shown in composit logger.

Plz support VVT on Daihatsu 3cyl ignition mode.

[francia]

And one more request, table switch source of Fuel Map and Ignition Map adds "coolant temperture" for VVT.
I think VVT works and do not works need different Fuel VE and IGT value.

[jsmcortina]

I'll be trying out your MSQ for the config error soon.

James

[francia]

I was confirmed again, MS3 pre-1.4 alpha 6 do not arrow to use VVT and Boost control on Daihatsu 3cyl ignition mode(3+1 triiger wheel).
And VVT and Boost control values are not included in the msi-log.

PPT0 and PPT4.jpg

PPT4 is Intake-cam 3 tooth signal for VVT?

[francia]

I attach the log.
Pls check its not inclued Turbo and VVT values.

[jsmcortina]

In the MSQ you posted, you have the wrong wheel decoder selected. VVT is allowed with "Daihatsu 12+1"

What is the boost issue you have?

James

[francia]

Note, I have informed the matter of following.
I need to use VVT and Boost control on Daihatsu 3cyl ignition mode(3+1 triiger wheel).

>>I swaped the Daihatsu engine EF-SE (NA 3Cyl. 660cc OHC 6valves) to EF-VE(DOHC 12valves VVT NA)+EF-DET(DOHC 12valves Turbo) .

Hard to understand Daihatsu super technology, EF-SE Engine and EF-VE:EF-DET Engine has different type of IGT trigger wheel.

>>EF-SE Engine timing : 12+1 tooth trigger wheel on cam << I'm not using this EF-SE engine now.

>>EF-VE has two trigger wheels for VVT.
>>Engine timing : 3+1 tooth trigger wheel on cam
>>Cam angle : 3 tooth wheel on cam

Ignition output signal have somehow inverted(shown ppt0), so that I choose ignition input capture is "Falling Edge".

Using MS3 pre-1.4 alpha 6, I selected the palameters that using VVT or using Boost control, but MS3 informed me do not use them on Daihatsu 3cyl ignition mode(3+1 triiger wheel).

[jsmcortina]

Hmm. That's not likely to work very well. The 3+1 cam pattern is the least accurate ignition timing configuration possible on that engine and I'm not sure how well it is working.

James

[francia]

Is it the hard way to control VVT using 3+1 IGT trigger wheel ,resolution of the CAM angular velocity is insufficient?

And basic question,
"Trigger Angle/Offset" = "0" on Daihatsu 3 cylinder mode , is it correct ?

About Boost control matter, I checked Boost control parameters and confirmed that Daiuatsu 3 cylinder IGT mode could control Boost control.
I missed its parameters, " Boost control settings 2"="use" and "Boost control pin 2" set "Boost" same as "Boost control pin 1"

Sorry for misunderstanding.

[jsmcortina]

I've allowed VVT with this mode. However, I'm not sure how well it is working and it may need some tweaks.

Remind me of your email and I'll send a test code.

James

[francia]

I'm sorry answer is too slow.

From the head gasket leak water was lingering to repair the water enters into the engine.
And I installed 36-1 trigger wheel for using VVT.

Today I was confirmed that VVT can not be used in pre1.3.3beta5 and pre1.4alpha9.

Plz give me pre1.4 test code allowed VVT using 36-1 trigger wheel.
If you can, I'll send email to you.

[jsmcortina]

Unfortunately you've changed from one unsupported configuration to another.

I'll have a look and see if it is possible to support this.

James

[jsmcortina]

I've changed the code so it doesn't report a configuration error and does look at the cam input. A VVT angle shows up. I can't test any more than that.

It will be in the next dev release. EDIT: Now available.
