Power FC basic set-up
I'm newbie in here and looking for some answers. We have changed our set-up to single and pri. injectors are stock and seq. are 1200.
If I have understand correctly the Power FC set up should be quite ok initially if I have done the injector set-up ok. But the engine starts only by pulling it by a wire and then it runs very rich. I have tuned the set-up much leaner but I'm still wondering if there is something wrong? Injectors are not leaking.
Second Is it normal to run almost 30 degrees ignition advance when the engine is idling?
Why the cranking injection timings are so big? In normal engines those values are too big.
Is there available good manual for Power fc (not fc commander) where I can understand correctly some set-ups?
thanks in advance

Basic setup -- switch seq twins to "off" and change injector settings per the PFC Commander manual.
If the car is having problems starting or running, then you have a mechanical issue, and not a PFC issue.

F1: We have changed our set-up to single and pri. injectors are stock and seq. are 1200. If I have understand correctly the Power FC set up should be quite ok initially if I have done the injector set-up ok.
A1: I assume you only have the Commander and not a DATALOGIT.
PRIMARY: Q = 550, Front and Rear % = 100.0, Front and Rear LAG = 0.00
SECONDARY: Q = 1200, Front and Rear LAG = 0.10
F2: But the engine starts only by pulling it by a wire.
A2: What does this mean?
F3: and then it runs very rich. I have tuned the set-up much leaner but I'm still wondering if there is something wrong? Injectors are not leaking.
A3: Does it run rich after warmed up or when cold?
Your base tune is always taken from a fully warmed up engine. After it is warmed up you tune fuel. If not using the ISC , then also do timing and air flow.
After completeing a warm tune, you do a cold fuel only tune the next day.
There is a water temp vs fuel table for this.
F4: Second Is it normal to run almost 30 degrees ignition advance when the engine is idling?
A4: Unless you have deactivated the ISC and are running manual idle timing, no way should you see that much timing in monitor mode.
F5: Why the cranking injection timings are so big? In normal engines those values are too big.
A5: Is this your first FD? NORMAL!
F6: Is there available good manual for Power fc (not fc commander) where I can understand correctly some set-ups?
A6; I sell a package of FD tuning and other notes. PM me if interested.

about A1: I only have commander.
about A2: It cranks but it doesn't start. Every time a had tried to start it with starter the spark plugs gets wet always.
about A3: Engine runs rich all the time. I'm still wondering why the PFC basic fuel maps are so rich?
about A4: In PFC factory IGL map it adjusts the timing to 30 degrees when idling. So much advance sounds too much.
about A6: What kind of information does this package include?
So the factory PFC settings are not even close to good settings where the tuning could be started?

Q7: If 02 feedback is disabled should PFC have lambda sensor connected? I have wideband but I haven't yet connected the wideband meters simulated narrow output to PFC. Should I connect lambda to PFC or just leave the connector empty?
Q8: How do I calibrate the TPS sensor correctly and how important is this?

2. Unless the PFC is bad, this is a mechanical problem.
3. Unless the PFC maps have been changed from defaults, this is a mechanical problem.
4. Don't know.
The factory settings are very good starting point and the car should start fine and drive around in vacuum reasonably well. Your problems indicate A) a bad PFC, B) bad settings on the PFC, or C) a mechanical problem.
Make sure the PIM Volt setting is set to NORMAL if using the stock MAP sensor.

8. There are write-ups in the 3rd gen forum. VERY important! If you have to ask this, you probably should NOT be tuning your car!
