I have just had a PFC installed and the car and tuned at Racepace.

Ever since the PFC went in, I sometimes have an issue starting the car.

When it happens, it will crank over but wont actually start. I never had an issue with the stock ECU.

It usually happens when it's warm, and I can never judge when it will happen.

I have attached a photo of the sensor check screen on the PFC controller. Is there anything off here? Is this something I can sort out or should I just bring it back to Racepace?

My power fc is doing the same thing in my r33 rb25det. I changed the cranking ms at 50 degrees from 11 to 9ms and at 80 degrees from 10 to 8 ms. It seems to start with less cranking but still not perfect. I noticed that while it was cranking the ignition timing was only at 3 then 6 btdc before it started. I spose there must be a way of changing this?

Just an update...

Racepace have advised that it is likely the fuel pressure regulator is faulty, as a result of the car not being used much by the previous owner and fuel corroding the diaphram.

Will let you know results once new FPR has been installed....

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok so will run the piping over that radiator and no plenum it is. Put that money towards a Haltech and see what suits. Any ideas something like an elite 2000 or 2500 right? My long term goal is 300kw e85 and manual swap and that’s a dream come true. For now will be 200kw and auto the stock rb25det neo intake isn’t too expensive with throttle body. If I was to have the port matching done, Would that be better than the stock de intake as the det has bigger holes plus has the spots for sensors etc? And suit more long term?  appreciate the advice?

      You understand AFR is not the only thing that contributes to it pinging yeah? Funnily, what the AFR gauge will tell you when it likely is pinging, is going to make you think things are really safe and good.

      Run the piping how we all have for decades. Also the duel runners with the +T setup dramatically helps it gets on boost quicker. Yes, chase huge power it'll become a problem, but you're a long way off when you're already saying an aftermarket ECU is out of the budget. You also say NisTune as it's simple, and then immediately say it'll be painful, meaning... It won't be simple. It will likely cost you a lot more stuffing around with a Nistune, than just putting a Haltech or similar in.

      I’ll order an afr gauge to keep an eye on it.  Then will get a haltech soon

      TD05 or maybe pulsar PSR2867r Gen 2?  id love a garret but it’s quite out the budget for now and I’m not chasing crazy power.    yeh fuel pump haven’t looked into but whatever works, kind of last on my list.    Nistune because it’s simple but Ik it’s a lot of pain especially as I’m auto +t with the whole seperate TCM etc still investigating that. Haltech id love but once budget tight for now atleast.    finally the reason I’m trying for a plenum instead of the stock intake is I already have a standard Intercooler mounted etc. so the ports are on both sides so trying to not have to go over the clutch fan radiator etc. trying to find a good deal return flow if I don’t than this will do for now I guess. btw any ideas with that, apparently some people have to cut blades to reduce it from hitting the Intercooler piping over the radiator ? Thanks
