Mazda MX5 VVT

Hello
I am looking for an MX5 VVT basemap
I want you to tell me that the trigger offset is not known

Thank you

The trigger offset is not known!  Hope that helps.

 

There are potentially 2 variations of the NC trigger pattern.  One uses the "MX5 VVTI" pattern as expected, offset is normally around 0 (but you should always confirm with a timing light).  The other has the cam signal inverted and uses the Suzuki swift V2 triggermode, the offset is unknown for that engine.

I'm sorry
The model is NB8C and the engine is BP-VE
Is there any information about this engine?

[Adamw]

Actually looking at it again I was party wrong in my last post, the NC uses the Mazda 3 or suzuki modes.  Your engine should use the MX5 VVTI trigger mode and the offset should be around zero.  4 teeth on the crank and 3 teeth on the cam.

Thanks adam

I made the offset 0 but it was useless
I want to adjust it because the timing is off like the image
Changing the trigger offset value does not change the timing
I do not know why the timing does not change
Of course, it is memorized by ECU with return key and F4 key

 

[Adamw]

Are you sure you hit enter when changing the offset?  The field should turn blue if you have done it correctly.

[o_dd]

Yes, the enter key is pressed
I'm verifying that the field is blue
I remember in the ECU after that

[Adamw]

If you open the set base timing screen again, is the new value still there or has it returned to zero?

[o_dd]

The number is not 0 but is a modified number

Hello
I tried to run EVO Link (I-III) on MX5
But the result didn't work as it was in the past

When I connected my WRXLINK (7-9) it worked fine

But EVO Link (I-III) does not work properly
Is this a malfunction?
Does EVO Link (I-III) convert trigger input on the bottom board?

[Simon]

EvoLink has might have issues if trying to control 4 coils as it has additional circuitry on the ignition 4 output. 

There is also a pulldown resistor on the Di1 input.

But as far as triggers go this should be fine.

Thank you Simon

There is a possibility of initial failure
Talk to the dealer you purchased

Isn't it a mistake of Di3 input instead of Di1 input?

[Simon]

Di1 has the pull down and Di3 is wire to the ECU hold circuit. So both will not be suitable for regular Di operation.
