Quick Powerfc Question

[Lachlan33]

Hey Guys,

I have bought myself a power FC, hopefully getting here this afternoon or tomorrow.

It is my understanding that the base map on it will be safe to run the car with for awhile before getting a tune yes? I have stock injectors and AFM, stock turbo running around 11psi.

I can just replace the stock ecu and drive the car like normal? How safe is the stock PFC map? And in theory could I drive the car every day for say a month or two without having to worry about getting a tune, or should I wait until I can get a tune done at the same time?

On an unrelated note, when booting it in my car, usually in 2nd and 3rd gear, full throttle results in lots of popping and sluggish acceleration, but say 80% throttle it pulls hard. I am thinking either lower gapped plugs might fix this or perhaps my coils are stuffed. Thoughts?

The basic PFC questions are covered in the PowerFC FAQ

Have you read it?

no problem driving the car for a while on the base tune. personally I wouldn't be taking it to the circuit or drag strip in that time but just driving around will cause no problems.

I have yes, it is very usefull and I will be using it as a reference while doing the swap. It does breifly mention that the base map provides more torque etc etc but also reccomends a tune (obviously)

I just want to make sure that until I get said tune, I am not risking my engine by driving to work for a few weeks.

the problem with your car accelerating sounds like a coil issue had the same problem with mine only when i stamped on the gas the car would miss one hell of a lot check all my coils to find 3 had been replaced with new items and the others were still original pulled them out and found cracks in them replaced them and haven't had any problems at all used to be kinda scary when over taking and you plant the foot and the car just doesn't seem to pick up fast enough and you've got traffic heading your way

Haha yep, I have to make SURE i have plenty of space when overtaking to allow for a few periods of poor acceleration. I have suspected my coils for some time but never actually inspected them, I might pull them this arvo and do a visual inspection, see if there are obvious signs. I would happily buy some splitfires but they aren't exactly cheap.

i replaced mine with second hand tested ones really cheap and haven't let me down you should definitly see the cracks if you have them look down the front and back of the coils

Ok I got the Power FC this afternoon and was determined to get it all working myself.

Put it in, attached Loom. Car dies within 1 second of starting. Yes I cleared the previous data and also set the boost control option to off. It seems to be saving data fine, the car just won't start properly. Starts, gets to maybe 800rpm then dies. Giving it some throttle makes no difference.

Any help is much welcome

EDIT: Ok is running now, I had a Safc before which I had disconnected, plugged it back in but set it to not do anything, PFC is now idiling the car. Must be some wiring issue.

spent 5 bucks on a tube of ultra blue(gasket silicone maker) covered my coils to insulate them, never had a problem again, even when running 16-17 psi, its tight arse and doesn't look good but beats spending $100s of dollars on splitfires...

Hope this helps.

Ok just got back from a quick drive with the PFC. And holy crap, even without a tune I love it already.

1: Car no longer pops and bangs every gear change or throttle lift (not that I really minded that )

2: With an Atmo BOV I used to watch the revs dip very low and have to catch it or risk stalling (made stopping at lights a PITA). Using the PFC I set the idle to 800rpm and this problem now does not exist. It hunts a little but never dips below the 800.

3: I have my full throttle back! Its been quite awhile since I have gone WOT in the car because it would just start to miss, pop and bang and my acceleration would go out the window. This is now 95% fixed, the car pulls hard again. I heard the odd pop here and there a couple times but its chalk and cheese to what it was before

4: The car overall feels more like a proper working car again and not some backyard tuner deluex with dozens of minior issues I had gotten used to.

PFC FTW!

PFC FTW!

Just wait till its tuned to your car and mods

I guess next step is Z32 AFM, bigger injectors and a new turbo
