as you know I just started my FD but I can't go above 2500 - 3000, i'm not sure if it's boost related or not and don't know where to start to look..
Here is a vid... RPM VIDEO FIRST START UP |
Is that RPM vid with your foot to the floor the whole time?
|
had somewhat of a similar issue when i left a rag after reassembly..
and new pfc install....it cleared up after learning the car... |

You just put your PFC in?
If so, just let the car run for like 30 mins, shut it off, then start let it run for 20 mins. Start is up again and 20 mins again. Then start it and start playing with your tunning if you need it. This is what we did on my car and it worked out pretty good... |
Thats a buttload of smoke... New engine? Didnt start if for a long time?

OOOOO hummmm and thats it? How long did it run before you started to press on the gas. Most rebuilders here let it idle for almost an hour on a new
motor sometimes more... Hummmm does sound good, but hopefully your still good to go... |

so your saying it's still learning??
|
weird... i've started it over and over... no starting problems now... It still won't go over 2500... I noticed i forgot to lock my fast idle cam.. so that helped my idle a little...
question... what if i keep disconnecting my battery? does all the pfc settings get lost?? and does the pfc always have to learn?? |

anyone please confirm...as ive had my battery die on me for a good while without ill effects to the pfc settings.. jay..could your issue be mechanical like the throttle cable...just a stab |
No you wont lose your settings...
|
update....
I unplugged the O2 sensor to see if that would make a different... and it doesn't... I then plugged in the stock ECU and now I can rev past 2500 with any fuel cut... so now i'm thinking it's a setting with in the power fc... maybe it hasn't learned enough?? I have no clue... can anyone else help?? |
over half an hour on idle before i was able to exceed 3k rpm in my install...
just had the hood up with blower on the rad and ebay as it was a warm day... |

CHECK THE PFC SETTINGS!! there is a setting for rev limit. maybe for some reason it;s set low. Also check what the boost settings are. If they are low, it may be hitting fuel cut, I dounbt it, but you never know

WOW dude, there's so much **** to **** up there, I'm considering NOT getting the Comander!
|
looks like the factory settings.
Still no luck? Hey did you get those 4 wires (or prongs) removed already? |
Well except for the seq.turbo cont (symbol).

Your problem is likely in the first picture.
Both of your temperature readings are very high, and the HWL light is on. That means you have a problem, because the HWL is used as a check engine light by the PFC. I can't remember if high voltage means high temperature or low temperature, but I would bet your temp sensors are not attached. See how VTA1 is shaded? That means that one is the problem. Check your manual, cause I gave mine away when I sold my PFC. See which sensor is VTA1. |

The Commander is essential to have, as you can monitor everything without lugging a laptop around with you. |

Jayspec7...
are you using stock injectors still? i see that you are non-seq as well? Any more info on mods you are running? |

[/quote] Pardon me about the temp, you are correct it has been a while since I messed with it. The attitude is not required. There is still something wrong there. Perhaps the TPS is not connected? Read this thread for proper VTA1 & 2 readings. The PFC does shade sensors that are not reading right when the HWL light is on. Why would you be able to 'select' a sensor reading? Which sensor has this guy "SELECTED"? |

If you think that's complicated you better sell your car right now, or leave it completely stock.

The first 2 are tps voltages. 1 narrow, 1 wide. |
jay you take that picture???
here is one that I have, do those 0-rings we talked about go where I have the arrows, or under the assembly directly ontop of the air bleeds? |
thanks for all the replies... the pics of the dilsplay wes taken w/ the car off and ignition on... i don't know if that makes a difference...
my mods follows... streetport non seq intake catback downpipe ngk 9s all around taylor wires ground kit DT/EGR/AWS/ACV disabled |
Unless you had your foot to the floor it must be the TPS. The signal should be low voltage. Do the same thing and step on the gas pedal, see if the readings change.

ok... after trying different things... I called one of my buds that had an extra TB w/ the TPS on it... we both measured out the resistance levels and made comparisons...
Being that I tried to take the TPS housing and TPS off to get polished, there was a chance that I may not of recalibrated it properly... my PFC was reading 4.xxV narrow and 4.xx wide with the motor warmed up.... After recalibrating to the same resistance values as my friends TPS, I went ahead and tested it out... turned the key and looked at the VT01 and VT02 values... whoa.. they where very different.. looked normal and they changed as I hit the gas... so i started it right up and waited for it to warm up... a few minutes later, I take a little test drive.. WOOHOO THAT WORKED!! I just noticed that once I stopped at a stop sign, my car felt like it hesitated, probably coz of the maps of the power fc.. could be running really rich... Well, i'm goin to finally get insurance and register my FD next week, but can I drive around keeping it under 3000rpms with the base maps the Power FC is loaded with? In any case, I wanted to thank you guys for your support and all the help!!! https://www.nopistons.com/forums/pub...IR#>/bigok.gif |
congrats! it should run fine with the PFC base maps...

Wooo hooo glad you figured out the problem!!!!.. with the stock map, you really have to worry more about how much boost you hit, rather then rpm's.
If you want, for now, I can load a map for you https://www.nopistons.com/forums/pub...IR#>/bigok.gif |
