  1. Hi all,

    If someone can point me in the right direction, that would be awesome. Have my Barra N/A GQ Patrol, have it tuned up, but want to improve the throttle responsiveness, as it's a big car. Don't need drastic changes, just a bit, but every time I make a change, it throws codes at me. I've not changed the minimum & maximum, but have tried the following:
    - Changed auF0083 & 84 to a 'similar to FG' curve

    - Changed auF0083, 84 & auF077 (Desired Throttle Angle) to match

    - Changed gain to FG (0.3)

    - Changed a small amount in the above tables

    No matter where I change it, it seems to clip and have a fit. What am I missing? I can't see any limiters in the Drive-By-Wire settings either. I even threw everything FG in there that relates to throttle (I have an FG throttle body & manifold) and it still failed.

    **I understand these settings can cause big problems, but only looking for small changes at >40% throttle.

    Thanks!

  2. I've done similar to what Roland is suggesting (also a manual Barra GQ), I have an FG throttle, and have put the BF airflow numbers in it for idle. Has helped lots, but needs a bit more. I'm working on getting it to be better at pulling off the line - So messing with it further r.e. airflow may help more.

  3. Bit of a thread mine, but I've been playing with throttle settings on my BA gas motor with FG cams & inlet, and its a bit of a prick to get working. (BF PCM - HACCKBC). Can't seem to get throttle settings to stick, even if I copy the entire Drive by Wire / Pedal & Throttle limits tabs from the FG HAEDDEZ tune. Seems to get to WOT too quickly, then throws an ETC code at me. Will keep at it and let people know if I work it out. I'm assuming the BF PCM doesn't have a function or something, or the BF pedal has different voltage ranges? (FG T/B)

    It's in a GQ patrol, so bit heavier than a falcon. Needs a bit more responsiveness!

     

    Any help would be great, but understand the disclaimers :)

  4. Thanks Roland. Great work on the logging release btw.
    When tuning a vehicle on the dyno, is there suggested settings to disable knock control (to find proper MBT & Borderline spark values)?

    A shop in my town has just installed a dyno, so I'll rent some time from him (costs permitting), and tune this thing properly.

  5. Is there an RPM ceiling the factory knock control will pull timing at WOT? I've got an early eGas engine in my patrol (10.7:1), with FG inlet, BF ecu and cams. Have adjusted timing according to the knock logs at WOT. I haven't had my knock ears on it recently, but it sometimes blows a bit of white smoke at WOT at high rpm. Doesn't seem to be pulling timing.

    Does it have a rpm where knock control stops controlling timing?

  6. I'll have to do some logging on my FG, would you be willing to list the data (i.e. what the messages are for) for what you've found?

    I've been messing with BA, BF & some FG Can-Bus stuff, its cool but sometimes a bit tedious.

    Here's my list of what I have so far, I'll update it when I get some more. You've probably identified alot of it already though.

  7. Thanks @finnigan001 - Have had a look at that one, that would be massively tedious on one of our ECUs though? To reflash and run it up on the dyno every time a timing change is needed?

     

    The reason I'm after some sort of logging of BSFC (brake specific fuel consumption) is to get the MBT table mapped properly for cruise / part throttle timing.

  8. Is there a recommended way to log injector duty cycle (bsfc) to get the cruise timing in the ballpark on the road?

    Currently using an SCT X4 to log, I haven't managed to find a reliable way to do it yet. Suggestions would be welcome! Got the knock-limited spark pretty right with knock ears, but the MBT non knock-limited stuff is proving harder.

    How do dyno tuners do it with the reflash-style ECUs? Just do a few pulls at specific loads and speeds, change something then try again - While logging torque output on each run?

  9. The reason I'm changing cruise timing is because the engine is pretty modified from a stock BF XR6 engine, mainly the inlet manifold and extractors which would be affecting spark advance and air charge. And I just want to check that I'm getting the right values in there for engine longevity.

     

  10. Hi all,

    Any recommendations on how to refine cold start? My Barra swapped GQ Patrol runs and drives amazingly when warmed up, and starts really easily (even cold), but the power delivery is pretty shocking until it does warm up. Doesn't miss or pop, just way down on power and not smooth. I don't remember any BA/BF falcons being like this.

    Any tips / tricks to making it run *not* like a bag of dics on cold start?

    Cheers.

  11. Hi all.

    Is there a way to log instant fuel usage via SCT (or hopefully the PCMTec logger when it's released) from the injectors on these PCMs?

    I'm looking to do some road tuning for fuel economy, I have the fuelling sorted, but would like to optimise the ignition map for cruise. At the moment it's a shot in the dark, could be over advanced etc.I've been logging it using SCT, all the knock-limited spark tuning I'm much happier with, and it's running much better under throttle so far.

    If I can log the average instant fuel usage (injector cc/min?) and average speed with cruise on, over a consistent road, I'll be able to figure out what the engine likes best.

    Thanks in advance!

    I've got a full plastic FG inlet on my BA motor, didn't need any tip in adjustment to make it run well, just a bit of slope and fuelling adjustment.

    Does the XR8 throttle fit straight on?

     

    Note I changed the injector data to FG as well, to suit the new injectors in a BF PCM (HACCKBC)
