Just to flog this horse,

The new Link G3 w/ PNP adapter will support only 2 injector drivers, and it will support 4 ignition drivers? Am I correct? Is there not a way to run sequential fuel injection?

To add knock sensing, does it require adding just the sensor itself, or does it require the knockblock as well?

Does the G3 "autotune" or have some sort of assisted fuel tuning capability?

Adding the IAT sensor is reasonable. Does it also require adding a coolant temp sensor, or is it capable of using the existing sensor?

Thanks

Mr. LEM- did LinkElectro even consider making the display an input device too? Just seems like that would be the "complete" solution, rather than having separate input and display peripherals.

I worked directly with Link Electro getting the LEM wired into my Motorola Cup NB - to my knowledge the first link in an NB. We figured out that all the NB signals were "ultra" low voltage compared to the NA's 5v signals and that the noise filtering capacitor(s) were cutting out all the trigger signals above 3k or so. I'm assuming the G3 is capable now with most modern sensors using less voltage.

We also used the NB cam and crank sensors - the cam set coil phase, and the crank was set up to trigger spark. Fun stuff, and I gotta say that the guys at Link Electro were absolutely committed to project- answering my questions the very next day with direction to ultimately find a working resolution. How's that for a vote of confidence?

Ben: Yes, thats correct the LEM G3 has four ignition drives and two injector drives. Note that any engine can be run using group fire injection, Also all four, six and eight cylinder engines can be run using four ignition drives. The catch is that you will not be able to do sequential injection and on engines with more than four cylinders you will have to group coils or use a wasted spark setup. Our higher end ECU's provide eight ignition and injection channels for those who want to run full sequential fuel and/or ignition.

The LEM G3 does not have capability to measure Knock. You could use another box such as the KnockBlock to put a 0-5V Knock signal into the An Volt channels. Aghain, our higher end ECU's have dual input closed loop knock control for those who require it.

At this stage no "autotune" feature has been enebaled for customer use as we find that people tend to use them without doing proper tuning practice which results in a poor tune and an unsatisfied customer... no autotunes can completely tune an engine management system to the standard a good tuner can acheive...

All our products are designed to maximise the use of factory sensors where they are fitted. The ECU must be used with a coolant temp sensor, but the factory one is OK.

I assume by input device you mean a tuner? The reason the DisplayLink was never used for a tuner was due to the complexity of the engine management system (also the same reason hand tuning modules are no longer supported). There are far too many parameters to be adjusted through the display. Remeber these ECU's are much more sophisticated than our earlier ECU's.

LEM G3 ECU's use a new high input impedance trigger circuit with user adjustable filtering and trigger thresholds. Changes are no longer made by modifying the hardware, they are done directly through PCLink.

Haha, cheers for the vote of confidence, I would like to add that we still offer the same level of commitment and support... Thanks for the compliment...

Default Really interested in seeing a setup

Im really more interested in the application of one of these units than what it supposedly can do.

For example - someone buys a megan racing manifold, and a 14g turbo the link unit should do....

or the greddy unit and using the link it will help you..

Otherwise..im thinking why is thisany better thatn say an e-manage or bipes or SMC or whatever.

What exactly is the application as it relates to a miata??

it is a standalone engine management system that is fully programable so you can get your engine tuned "exactly" how you want it to be tuned (or at least damn close). The bipes, SMC, Emanage (well emanage is pretty powerful), and some other tuning solutions will not be as precice and there will be tradeoffs.

Lots of people run link engine managment.
Flying Miata has been selling the link for years.

Yeah, but I don't know anyone running with this new hardware.
I volunteered to guniea pig it, but never heard back

Really a shame, their group buy price was pretty friggin good.
