PFC Pro help

[GunMetalR33]

I just put my pFC into my GTS-T and things are not going well.

I am just running with the base map at the moment and have it booked in for a tune for late jan.

I have a turbo smart bleed valve running 13psi on high and stock on low (about 7psi).

When i have it set to high boost the car runs like some body has put a orange up the exhaust (it almost feels like some sort of really fine ignition cut)?

On stock it run OK, I though it might be the fact that the PFC's base map is not designed for our fuel, or maybe the PFC does not run with bleed valves?

PS, there are no warning lights displayed or anything like that and the car is holding boost so I dont think there are any leaks in the piping for the FMIC or anything like that.

Any idea's

No reset needed

I would be careful about pushing it till you get the a/f ratio checked.

On hi boost it may be getting a lean out situation cos of a tired fuel pump.

Hi GunMetalR33, I would have someone watch the Commander readout when you are driving it at full boost. If it is retarding the ignition timing or adding some fuel it will show up on the screen. This is not dangerous, in fact the ECU is protecting the engine.

Another issue may be the AFM maxing out its voltage, this is a dangerous situation. You can also easily see this on the Commander. If it is running lean it will result in knock which will show up on the dashboad warning light as well.

I would try running the boost at 10 to 12 psi and see what sort of results you get. It may be at 13 psi you are just "over the limit".

Hope that helps

The base map may be fine for some people but it may not be fine for everyones car with infinite variety of modifications.

I would be watching the commander very closely especially the knock sensor reading.

I found that with the base map on my car it knocked too high at full throttle so i pulled it out until I can get it tuned.

I ran for ages on base map, but with only 0.6bar boost.

When my car went on the dyno to be tuned, I was glad I had kept the boost low, as it was still running very rich on boost and had AF ratios in the 10s.

Once it was tuned at 0.8 bar, with AF ratios at 12, it still had nearly 90% injector duty with stock injectors and fuel pump. Also, my AFM had run out of resolution (5.115V) by this stage too.

OK, I just did a run and have decided that the PFC is performing ignition cut when over stock boost!

Has anybody out there run a PFC with a bleed value (not electronic boost controller)?

Ps, There are no warning signals lighting up...

I had to tell the PFC that there was no boost controller to get the car to start.
