miata link pclink compatible?

[cole watson]

hi as the title sugests, is the miata link plugin ecu able to be used with pc link for tuning i have pclink v2.5 and a serial link are they able to be used together? my ecu started out with a link chip them got a flyin miata chip but have now gone back to a link chip. i didnt think the link chip was pc tunable but acording to this site pclink v2.5 should work any help is greatly appreciated cheers cole

Hi Cole, I'm afraid MiataLinks (no matter what the chip) were never PC tunable. -Cameron

When equipped with a Flyin' Miata chip, the MiataLink is completely PC tunable using DataLogLab.

[Cameron Moore]

My apologies, I should have said 'PCLink Tunable'. I don't have much experience with DataLogLab, but I was under the impression that you still can't tune the ECU with it.

[Keith Tanner]

DataLogLab was actually written specifically to provide an analysis and tuning tool for the MiataLink running the Flyin' Miata software.

If I remember correctly, the original name was "Miata Link Lab". Once it was expanded to analyze logs from other ECUs, it was renamed. There's your trivia for the day.

[Cameron Moore]

So you can edit the fuel and ignition maps in a Flying Miata Link, using DataLogLab?

[Keith Tanner]

That's correct. Fuel, ignition, start settings, accel enrichment, air temp correction - every zone is editable. It's a nice piece of work.

A bit of a thread revive sorry. How do I set the timing with a 'MiataLink'? (i.e. I understand you're no long able to use the jumper-connections as you would normally on a mx5 to connect a timing light)

I have a miataLink but no handcontrolller. I can connect/log through the serialLink using the 'Data Log Lab' program. I also have the 'PCLink' software (v2.5) and a serial to USB cable through virtual COM port 4 but can't seem to connect to the ECU that way. 

In the Tuning instructions (https://www.flyinmiata.com/support/instructions/ecu/ECU_tuning.pdf), page 7, it states that you've got to match the CAS timing with the value in the ECU but only mentions how to access the set-timing mode through the hand controller. 

I marked the CAS position on the old engine before transferring it across but, silly me, a) marked it on the back of the engine where I cant see it and b. marked including the washer (which moves). 

Any ideas how I can connect to the MiataLink ECU so I can set/check the timing using a timing light? 

[timmo]

Just a bit more info and another question. The DatalogLab file indicates IADV (Ignition advance) is set to 10 Degrees in the ECU (at idle), which is standard- I don't need or want to change that, I just need to adjust the physical timing through the CAS to match that.

Is it still possible to get the required signals to a timing light by using the method you'd use on a standard ECU? (i.e. jumper between GRND and TEN in the diagnostics port)

You dont need a jumper or anything just put a timing light on the engine when it is idling and shift the CAS until the marks on the pulley show the same value that is displayed in datalog lab.

[timmo]

Ok I'll give that a go....Is there a riisk that the ECU will 'fight' changes to the CAS timing though?

I noticed however that the graphic in dataloglab was initially showing 10 degrees, then changing to 5 Degrees also...?

No.

I have never used datalog lab and dont have a copy, but there is probably a setting in there somewhere that allows you to "lock" the timing to a fixed value.  If you cant find it then you will just have to do you best to interpret whether ecu is commanding 5 or ten, You may also find it settles down to a steady number if you bring the revs up a little..
