Hallo again, yesterday i've tune the evo 9 for hill climb I was talking about on the other topic, on dyno... anyway, every thing is quite good, but.... i've got only one odd thing I could not explain: on very first wot (after about 4 hours of dyno brake in) i had a single trig 1 error: Note: this car has kiggly 12 tooth kit and modified ex cam weel as kiggly suggest. Trig scope is quite good, each trig 2 edge is far from trig 1 edge (see scope attached). After this only one issue car runs well all day long. My question is: what can be the cause for this trig error on my setup? tks, bye Trigger Scope - 2024-04-23 12;28;19 pm.llgx trig 1 err on 5500.llgx

Yes Adam, finally I get the same solution importing "Link Genric Dash" file in ADU. It works , still have some value to link correctly but i'll check better in these days. tks bye

Ok, find ID is 1536 in decimal, but frames are different...

Hallo everybody, dose someone alredy used ADU dashboard with link ECU? I'm tuneing an evo9 for hillclimb challenge that alredy have this ADU dash on. I've tested to set as generic Dash and other type too, but do not display enythings: I think CAN line is ok because during the "test device" opartions some value are display, as gear 8, 7.4V battery and some rpm value... can someone suggest me how to set it properly? tks bye

tks Adam, i'll rise that value. I'm used to calibrate tps in wot a little bit before the total pedal stroke , to ensure that in wot position calibration records a stable value of 100%. And what about pinout? I remember the same issue on Evo8 g4+ ecu too... Evo9 p&p is ok instead. tks bye

Correct, my (rough) update table is set in this way: So was 10Hz and 5 sample --> 0.5sec reactivation delay, but in log the lockout wait more then 2.5-3 seconds....

Hallo everybody, first question is about evo8 G4X p&p pinout: on installation manual is indicate that the clutch input is connect to pin 46 -> DI10 but on oem EDM connector this input is on pin 43, and also pin 46 on link ecu is not connected to DI10. Second question: tuneing this evo8 in close loop lambda mode, i'm asking why %TPS lockout remains active (for several seconds) in this log (2nd, 3rd and 4th WOT with flat shift): Ok, I've set a very sensible value of lockout: but TPS in this log is stable at 100%, why this happen? bye Filippo wot 2-3-4.llgx

Ok Adam, now DBW it's ok. tks. bye

Hi Adam, nice to read you again. Yes you are in right but that is the reason why accumulator rise in that way? even if signals are coherent?

Hallo everybody, i've got error 77 on my new evo8 g4x tuneing, but I can't undertand why! My pedal have 2 ouput signals where 'sub' is 50% of 'main'. Signals looks good, but why APS error accumulator grows in this way? Is this driven by difference grater tha 6% between main and sub voltage or scaled percentage? and after that reach faulty delay and stops: Where I am in wrong? bye Filippo

Adam, do you have some ideas?

here i am Adam: attached some log where issue happen, some differences in boost and fuel or ing cut, ALS on or off, but issue after clucth release persist even if is reandom,about 1 each 2. Also test with reactivation timeout set to 0. whait for your kind judment bye flat shift jerk fuel cut 1.4 bar log stack.llg flat shift jerk fuel cut 1.4 bar.llg flat shift jerk 1.8 bar.llg evo9RS --nlts issue -v2.21.pclr

Adam, i'm sorry if I bother you with this argument, but I still have issue with this flat shift: Yesterday I've made some test for ALS functions and during flat shift still have jerking behavior (with or without ALS), this time set as 'ign cut'. I'm sure to not have missfire issue (engine runs till 2 bar smooth and fast), but this happen also at low boost (1.4 bar) and always happen during reactivation time after flat shift. What more can I do? There is some method to make a 'low level' parameters log? that because from pc log i can't see nothing odd, no % of fuel neither ing cut but engine jerks and afr is not lean as missfire does, so I'd think could be a timeing issue or failure (random negative adv timening)... As told before, if I don't use flat shift system so releasing throttle as a normal shift, there are no issue at all.. I'm useing a oem gearbox and shift time is about 300ms where clutch remains engaged... Finally: Merry Christmas and best wishes from Italy!! bye Filippo

Finally I've tested with 0 ms, and that fix it up!! Also tested several boost presure from 1.5 to 2 bar but result is alway the same. another test fith only 20ms and car runs better, not jeatking, but not smooth as if time is set to 0. Adam, Any other idea or requested test for find out how to fix and use reintroduction torque? it is a pitty can't use that function... by Filippo

Adam, recently i've set knock target in function of clutch switch and his timer, it is a visrtual hinibition for CLL and Knk feedback, but no difference at least.. I'll make a test with torque introduction set to 0... but I really dont' now what else can be test to find out the issue... the feeling is like sparks plugs became wet of gasoline... but can't understand why if a relase throttle and wot again engine runs perfectly...

Hallo everybody, got a new question that I wasn't able to solve: i've set up flat shift on my evo9 rs in this way (DI input on top clucth pedal): The problem is that SOMETIMES as I shift gear (wot) and I release the clutch in next gear, engine start jerking as if mixture was extremely rich or just like a little 'cut percentage' remains, or even negative advance remains. If i suddnely lift throttle and wot again engine runs well (see log "jerk log.llg" shift from 2nd to 3rd gear). See also log attached wot2-3-4. Generally flat shift system work quite good even if the feelig is that durin reintroduction car don't run perfectly smooth but little bit rough... but still can't understand reason why: I've tested even fuel and spark cut mode but is the same. Looking to inj time and ing angle can't see nothing odd, also can't see any percentage of Fcut or Icut after clutch relased... so any suggestions? tks, bye Filippo wot 2-3-4 v2.18 ott21.llg jerk log.llg

Ok, that's clear now, as Adma says if input level is near to saturations there are no way to fix this limit, naither working on 2nd harmonic because distotions due saturation input could be an addiational input. I'm tunenig a second Silvia with 2jz and this time I've make the wireing and I know that trigger sensors and knock sensors wires are shield, and also in this case oem knock level input is high... Anyway ,as Koracing suggest, could be intersting work on 2nd resonance, but could be a reliable risk due saturation distortions... aftermarket knock senosr are cost affordable so can we say that this way is the best solution? Does enyone tried to put a resistor (470/1K ohm) in series for lower sensor gain ? Like a partitor or a balun?

On your experience is it possible ti 'make knock' 2jz (rebuld engine 8.5:1 cr) for test knock system revving around 3/4000 rpms at least 1bar boost? 2jz looks like to eat timeing adv in middle charge and revs, isn't it?

the US company is Wiring spcialties. I'll check if wires are shield or not... we've check several times for somthing machanical vibrations or possibile issue, but ther is nothing hitting... and engine is very smooth and silent to hear. but let me undertend: you run 1.6bar with greddy T88 on stock internal??

I also notice that your windows setup is quite narrow than std setup: 0-30 start-length instead of 10-50. What's your exeprience about that? tks bye

Engine is rebuild yes... What is oem sensor torque tighten value? I haven’t do that build but I can suggest owner to check this. Wireing is made new from an US company , could it be a shield or ground issue? Also this high level of noise is repetitive even stationary high rev rpms...

This is my last saturday test at 1bar boost (efr8374 and GSC S1 cams) with a simple knock target fix line @500. Setup very close to your at least, but knock sensor input signal is near to saturation, so dangerous zone.. Anyway i've just ordered 2 Bosch new sensors

and what about Fury G4+?

Tks Adam, so do you suggest to use motor sport Knock sensor like Bocsh one? this car runs with efr8374 and GSC S1 cams.. But i've used this in G4+ Evo9 p&p and G4+ Storm on another 2jz as well, look: how is it possible?

Another big question about this car tuning: we are useing a Storm G4+ for thia 2jz vvti, i've update firmware to latest 5.6.8.3671 but still can't see 'Auto Mode' in CLL... so can't tune al those features for a proper CLL behaivor... should be firmware the same for all g4+? Please Adam help me!
