  1. i just played with settings on a bf mk2 zf config, got it to spark only rev limit. but as it has a straight thro exhaust, its sounds really bad. non esential changes = AUF1415 engine speed limiting. change to 3/4 so it does not use ETC. i left it at 2 accidently and had to disable ETC as it kept using throttle limiting, however throttle limiting may be good to leave on as it will potentially save you. AUF0265 - Engine speed limiting - i set to 999 as its only NA wont get that high. But thinking back on it now, you could leave this and just set AUF0265. esential changes = AUF0265 - engine speed limiting - i had this set to 6k. but i would say set it to just over whatever you set fuel cut to. AUF0262 - Engine speed limiting - 0 - so max spark retard can be pulled. Auf0261 - Engine speed limiting - 1 - so it does not use this feature. Now this is where you have to play, the following is just what i tried today and it worked. but you might get better experimenting. (also i experimented at 2500ish rpm to make sure changes were working) auF1479 - enleanment - i had this at 0.75. AUF0144 Rpm Limit - set this to where you want your spark cut to occur. AUF11698 - amount of rpm it can exceed limit - 0 AUF12796 - time it can exceed rpm limit - 0 AUF0133 - RPM limit fuel cut - this is your actual fuel cutoff / end of the line wont go any higher. i set rpm limit to 5250 and it sat there around 5350 on spark cut. so if you have an auto making rpm limit to low might break your gearchanges. you will need to experiment. also you will prob break your engine doing this, i take no responsibility for how you take this information.
  2. have a look here. http://www.bulletperformanceracing.com.au/BA PPC Data Base.html you might get caught out with 5 speed manual vs 6 speed. the 6 speed has a loom for the reverse lockout and would defiantly need the PCM for that if you want it to work as factory.
  3. Barra PCM has no input for fuel pressure. I've had some fuel pressure issues recently and thought about just installing a under 50psi alarm using a pressure switch. Mechanically you could use a hobs switch in line with the boost controller that may deactivate the solenoid if its under a preset fuel pressure.... but that will bring you down to gate pressure not engine protection.
  4. Hello. I have a manual ba ute, was previously a 5 speed and now its a 6 speed. not thats its to relivant. How does the dash get its gear display information? it used to sort of make up numbers. ive noticed the last few times ive driven it tho it just says R. wondering if its something i may have accidently done, or it something i can fix or ignore?
  5. Howdy, auF1941 LTFT Enable - if this is disabled with STFT still be active? if there a way to reset the LTFT data? or is it done each time you flash the PCM? i noticed in forscan my LTFT was at 25 percent at idle. but starting going away if i held it above idle. at the time i was disgnosing a idle issue, thats required a replacement Throttlebody, repairs to fuel pump harness and while i was playing with pcm i played with the idle airflow table...so i proberly should put that back... but just wondered when ltft data resets.
  6. I put a BF Barra and ZF into R31 Skyline. The PCM did not seem to care there was no longer an ABS module to talk to, however it did not love the lack of speed input. The transmission absolutely hated the lack of ABS module and would go straight into limp mode...regardless of things i changed. Nigel from canbarra said the bf series ZF has a hard time if there is no abs module to bounce torque reduction requests from it will go into limp mode. I got a canbarra module to emulate ABS and basically takes the oss from gearbox and translates it into a ABS speed across the can... this keeps the trans and the ecu happy. now.....if your ba wagons TRC/ABS is not on the canbus? (strange) then its getting speed from the gearbox speed sensor i would assume. There is no reason why you cant tell the turbo PCM to use that particular speed sensor instead of the abs. If your keeping the BTR then it shouldn't care about the lack of ABS as the btr is run from the PCM. I would personally try the turbo pcm and see if you can make it work. you can disable the abs torque requestors to, so it shouldn't affect it running the motor. Alternatively you could try install the canbus trc/abs unit but it will mean doing some wiring changes and splicing into the canbus...its all posible it just comes down to how comfortable you feel about it.
  7. ok so i hit the trans button a few times, i have done this before but this time my computer was actually online...it connected and downloaded ZF-DMRs then they appeared. so it seems i can see the ZF stuff now. but does bring about my new issue. it seems to be ignoring the 1 to 2nd change...even at the lowest of throttle it wont go into 2nd untill its over 2krpm. the rest seem to work when you change them. strange
  8. is H8405 only in FG or Workshop mode? i cant seem to find it in BF/Professional version. id like to log this also, but dont seem to get much information out of the trans other than oss / temp.
  9. dont forget that table is at 39psi. if you have a turbo fuel regulator the fuel pressure is around 60psi. the FG f6 uses 440cc injectors, they may not be the same injectors as the ones you have but the data might get you in the ballpark. well close enough to testing's if you took those numbers (assuming u have a turbo fuel reg). try comparing your injector data against HAEE4V2. 0.7 is verry rich for a barra at idle, even inside the cold map. outside of the cold map the barra will use the 02 sensor lots and really try to hit 1.0...so your data is way off.
  10. I dont know if this is of any use to anyone else. Pcm speed loddged via pcmtech was changeable playing with the tyresize/mile figgures. Dash speed and speed lodged via obd2 (forscan) was different and unaffected by the other settings (tyre size). This is the speed source the speed cut uses.. supposing its ABS speed out. Playing with the abs to pulse modifier in pcmtec made no difference. As my canbarra emulates my ABS, nigel coded me up a way to change the pulse/speed out setting on the canbarra so i could change it untill it was right. So doing this i got my speed readings matching and correct. I cant recommend nigel enough, his support is absolutely top notch.
  11. Sorry its std falcon dash. Wired up to power n canbus as it would be in the falcon.
  12. Howdy, i am troubleshooting on the r31 again..so bf 2 na motor, canbarra, zf in a r31. ive been playing with the rotations per mile to get the pcm data logged speed to match the gps speed, and i have got there...but the dash speed seemingly does whatever it wants does the dash get its speed from somewhere else? does the dash have its own speed limiter? when i hit 180 on the dash it beeps and i get speed cut. (180 on dash usually around 110 normal kmhr). any help on where i should start looking would be greatly appreciated.
  13. is that AUF2565 TQ reduction, on my terry that's set to 3 but looks like its set to 4 on fg's? is 4 a straight to fuel cut?
  14. for notice, I have a fg TB and FG intake on a bf motor.. I noticed if I let it idle it would start hunting (rev up and down) but i knew the alt was not charging so figured it might be related. Last night was i able to get it to have some temp, iv started it numerous times cold no problem. Warm starts it would stall instantly. I noticed it was opening TB for start, then basically closing it.. commanding less than 1 percent blade angle. When holding the throttle down you could make it idle and the blade would be somewhere in the high 2, sometimes 3 degree mark. AUF0082 - open loop feed forward throttle angle predictions. This table is vastly different BF/FG and with the FG setting the car started and idled spot on. Ive just now noticed AUF1249 pressure drop table might also be worth having FG settings from. so far most of the petal/throttle angle settings altho they look different, or are setup differently have verry close to same reactions. so just changing a b-series tb for a fg one may infact just work. perhaps the airmas tables change due to the intake manifold change.
  15. yeah but the field allways seems to have a decimal number....does it want the MM rolling diameter as a decimal?
