Hey guys, small issue yesterday where on the way home the soarer started missing during light cruise at 2,000rpm almost like it was on the launch limiter, and the n it stalled out a few times and I was able to restart while rolling and continue more and limped home.

I have the powerFC installed and I bridged the diagnostics port and nothing shows. I don't think the powerFC has those functions.

I can't run the factory ecu because of the injectors..

I can't see anything wrong in the senors on the hand controller or in fcdatalogit.

I see O2H and RPG cycling when it starts missing. O2H is the O2 heater, no idea what RPG is..

I'm thinking of starting with the ignitor as they are known to fail and it feels like ignition cut, just wondering if anyone else has had similar..

Really want to sort it so I can dyno asap!

I'll pop the lid and have a look for anything obvious.

I had a good look at the board front and back and it all looks brand new (not surprising) and I played with a few connectors and drove around for 1/2hr without fault..

Guess I'll just have to see how it goes long term..

So it started playing up again this afternoon and after lots of testing I have all but confirmed it to be the PowerFC.

It was barely able to run for 3 seconds without dying and then I swapped out the PFC for the stock ECU, and even with the 264 cams, 650cc injectors and 3 bar map sensor it ran fine apart from idle.

I will be sending it off to FC-HAKO or Apexi for repair.

He may ask for you to log it and send it to him
However what you discribed sounds like what I picked up on this power fc and I had 2 faults.

Thanks Daniel,

I have been emailing him (John) back and forth for a few weeks now. I did send logs.

I'd be interested to know what it is and what caused it as nothing was done to the car when it started occurring.

Do you know what your faults were? Scott has the same issue also and John said he has seen a few like this now which is pretty weird.

As far as I know its a common fault with them.
Just like Sr20 power fc's have there faults.
I haven't really looked into them I sent it to fc as he fixed my old Sr20 one and know he knows his with them haha
