Yeah I had their first version of their PDM and it ran great until I noticed the melted fuse (about a year and a half) from them not disclosing it was only rated for 15A. But I mean it was still running even with the fuse like that. Probably would’ve burnt down the car at some point before it stopped working so glad I caught it. Definitely don’t think I would’ve got it in the first place had I known that. It was advertised as it completely replaces the need for the relays and everything so that was my main thing with it.

When mine blew the fuse it just shut the engine down. Not cool on an on ramp!
I was really happy with it until then, so hopefully all is well when I get it back. I really like being able to adjust parameters and see the benefit that they have. One thing I have heard is electric fans pulling too many amps. I had electric fans before so I just left that system alone. I was going to get the tune sorted and then wire the fans through the ECU…. Maybe not now.
I hope some of this isn’t because of our notoriously hot under hood temps. I thinks the ECU gets some cooler air but not sure about where I mounted the PDM. I may rethink that.
