My Power Fc Keeps On Resetting...wtf

Hey all,

My power fc keeps on resetting itself, losing all memory settings set with the tune. I am constantly having to drive back to my tuner out in Blacktown to get my settings restored with his laptop.

Its happened about 5 times now over the span of 3 months since i had the PFC installed on my '98 R34 GTT.

My tuner seemed to have narrowed the issue down to a faulty relay in my boot that had been clicking constantly on one occation. He didnt actually replace the relay though.

Does that sound right that my POwer FC could be resetting itself due to a faulty relay? The AVCR boost controller seems to hold its settings/memory when the ECU resets.

Im getting fed up with having to drive for 2 hours just to get my settings rebooted every couple of weeks and Im sure my tuner is getting sick of me too. He is asking if i want a refund on the ECU but I would rather have this issue fixed once and for all.

ANY HELP WOULD BE GOLD. Im hoping it is the relay rather than it being a faulty ECU. My tuner has also said that in 15 years in the biz he has never seen this happen before.....

Thanks

Con

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
