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.

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.

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.

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?

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.

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.

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

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.

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.

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.

Sorry its std falcon dash. Wired up to power n canbus as it would be in the falcon.

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.

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?

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.

ZF shift table 27 from memory, remove all the highlighted downshift figures and it will just stay in whatever gear its in. ive got mine setup something like this, so it wont ever downshift for you..... but it will upshift somewhere verry close to limiter. Just incase your reactions are to slow / rest your hand on the gearstick and move from performance to manual mode without realizing. cheers

AUF1964 smart alternator switch - prob good place to start

bf mk2 6 speed auto this is set to 4. ba t5 manual, tis was also set to 4

Canbarra have replied to my email with some verry useful information. In the fg the pcm can take speed directly from the ZF. in the bf the ecu still wants speed via either its b07 pin or abs via can - it cant take speed directly from the ZF oss. the canbarra takes the zf speed and puts it on the can in a way the BF PCM can understand. Bill.h did mention he has made a couple work without such a module, but its more so hit and miss with the bf pcm and might only be certain ones that can play this game.

I thought the ZF has its own speed/oss sensors so it didn't need wheel speed?

Hi Guys, is there an easy way to tell the BF ZF to stop looking for the ABS module? mine is going into limp mode and although it does not have reverse light/brake connected its other errors include the inability to find the abs module. regards

if it can detect backwards rpm for 0 wgdc then maybe...but wont it still give duity from 4.5-5.5 during change?

your turbo smart controller is not going to know when your gear changing, its only going to see boost values, so its going to try keep you at a certain duity cycle. when she changes gears it will pull timing to reduce power, inducing more boost a as by product. The FG turbo ECM has those gear change values you can dial in no duty cycle so your gate is fully open on gear changes. this will help your situation. as puff said, try lowering your spark cut on gear change, but keep in mind what other cuts the car will use.. FG na ecu looks to have around 0.5 as your trans shift modulation for spark cut. so if im reading this right it will pull up to 40 deg of spark, which will prob get you somewhere to your min spark clip of -15. not that i know what im doing, but ive been trying to keep my car from going into the negatives on gear changes with spark and it seems to help. you may want to experiment by changing AUf0262 trans shift from 0.55 to 0.75/0.8. if you do that make sure you give it some ability to use cut in AUF0264 as shift is 0, maybe give it whatever you take from 262 - but dont take this as law, just something to play with and experiment with.

did you change any settings? I'm about to put a fg throttle one mine and comparing things that seem vastly different are : AUF0077 - Convert pedal position to des ETC angle AUF0083 Desired throttle angle as per pedal position AUF0084 b as above couple of smaller things like throttle count wide open etc are marginally different

hi mate, how did you go?

the fgs goes straight to cylinder injector cut for zf, so with a b series you really want the car to request other tq reductions, then spark cut. so you can find the sweet spot for the burble with the other cuts - then use spark cut if it needs more. but i dont think this situation is reversable so if you disable spark cut to get the injector cut straight away, you will also likely induce etc cut
