Greetings,

I'm trying to benchmark a new cooling setup, and want to view some datalogs where I graph:

- Engine speed
- ECT
- VSS

So I can see how it is behaving on the road. The problem comes when I want to graph this. Even when I have data with temps over 200F, the graph display sets the Max for ...

I thought it would be good to close this out with more complete and correct information from checking everything I could think of before going ahead and hooking things up. Hopefully this will help someone else at some point.

First, I find on my ECU that E1 and E10 are shorted (< 1 Ohm). I don't ...

OK, good news. So, it looks like it is correct that the pin for the FPR Coil Return line is E10 for the PRC ECU. With the ECU repositioned I was able to safely get a meter connected to test continuity between E10 and Ground at power up:

The meter is off ...

For completeness:

I guess I can get the ECU where I can power with the cover open in order to test, but that kind of thing - probing a live board even with decent test clips for the connector leads - always makes me nervous. Also, once I get KManager working (have laptop here now) I guess I could set fuel pump to run ...

BTW, this seems clear/authoritative and is an example of conflicting information:

Here, it notes that the PRC ECU has no immobilizer integration (since JDM cars didn't have that), so there is no need to bypass it: that makes sense. It also says the FPR coil return is ...

Thanks for the quick reply. I'll be going through everything carefully so all good advice is appreciated!

Yes, I'd read your discussions of the FPR issue here and elsewhere, so I am of course concerned I'll find that the ECU is damaged. However, there have been other places on the car where I have ...

Greetings,

I'm new here, but will probably be back from time-to-time as I dig into understanding things on the EM side. I've got a custom car - Race Car Replicas Superlite Roadster - I acquired a couple of years ago from the second owner as a weekend toy. It's essentially a replicar of an Ariel ...
