Power FC Glitching

[Sileighty_85]

Kinda weird, about 3 weeks ago my commander started glitching.
Like Pixles everwhere and screen is mirroring one side until I moved the cursor over to that side and it some what cleared up.
I think it might be due to it being in direct sunlight too much.

Now 4 Days ago the commander would reset while im driving (like when you first power up the car) and everytime the commander would reset the engine would "hic-up".

Connections are good i wiggled the commander cable and main engine harness trying to replicate the problem, but no luck.

I unpluged the commander about 2 hours ago and seemed to clear up so far.

Any one had this happen before?
Is it something inside the commander that can be fix like a bad diode or heat sink or soldier point?

check the connection pins on the cmmander plug as well as the PFC too.

Make sure they are good

If it still happens I would call directly to Apexi and ask them if they have heard of that issue.

Make sure the commander is the right one for your ECU also.

Did you buy them together both new?

Yeah its all good, Ive had the ECU in the car since Jan. without any problems. Bought them both together (used though)

I wanna say it cuz of the heat, It gets pretty damn hot down here.
I try to hide the commander from the sun when im not driving it much but there have been alot of times i havent and the commander gets so hot the screen turns black.

I drove it today and it hasnt done it yet since i unplugged the commander.

well scratch all that crap^^

Power FC just took a dump on me.

Driving to and from meeting a guy about an S14 the PFC continued to reset more and more often to where now the PFC wont stay on, just keeps resetting.

LUCKILY I trusted my gut instinct and brought along the Stock ECU, MAF, Injectors and rail. so when it crapped out on me in BFE i was able to swap everything back and make it home.

So what was suppose to be a 3 hour drive home turned out to be a 7 hour drive home -o-
Damn i have not had good luck for the past month ;o;

Issue was Old Faulty wiring (ECCS Wire) on the chassis side brown plug in the battery area.

replaced plug and fired right up.

Commander was fired from leaving it in Direct sunlight all day during 100* days lol

Dumb question, but if u thought the commander was bad, why not just unplug it? The pfc computer still works without commander, right?

I didnt know the commander was bad until i sent off the ECU and commander to Apexi for repair. Yeah it will work without the commander.

When I got it back, they said no issues were found in the ECU only the commander. Plugged them in and still nothing so I started checking the harness and found the bad plug.
