BURN STOCK CHIP or PFC?

Guys,

does anyone have a preferred approach based on experience? i can go either way but i'm leaning towards the PFC specifically due to availability of experienced tuners. I've also heard it stated that the stock ECU won't adequately handle Z32 AFM or larger injectors and doesn't have the flexibility of the PFC; while outcomes will depend on the tuner I'm more interested in the inherent ability of the units.

Thanks

Hi Scooby, If you want to do a number of upgrades all at once, then chipping the standard ecu is OK value. If you want to a number of upgrades over time (tuning in between) then the PFC is much cheaper.

If youre going to do your own tuning with the PowerFC then im assuming that youre comfortable using the W/B O2 and changing around the settings in the ECU. You can get an EEPROM burner for $60US and chips are about $15US. You have to get the Wideband O2 either way and the software for ECU tuning is free. -In my opinoin- i would get the eeprom burner and do it yourself. Of course ive never wanted to shell out that much and use the PFC, so i dont have any expierence with it.

Does the software allow you to see what load points the car is using?

Unless you can tell that you a pretty much running blind with tuning.

I would definitely recommend the PowerFC and FC-Datalogit as well :D

      As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.

      I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc.

      Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.

      So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
