    Altezza+ PNP 3sge e throttle issue

    Sorry attached is the log. Still seems to be the same? The FPS calibrates fine every time. The TPS sometimes comes up Error 16:cannot reach target 98% but sometimes calibrates and sets ok. Any thoughts? Thanks Brendon E throttle with calibrated sensors.llg

    Altezza+ PNP 3sge e throttle issue

    Ok thanks for the info. I will keep an eye out on the accumulator. That error scenario seems slightly different to mine however as if it applies the 1800RPM limit it shouldnt stall out the engine?. When the rpm limit came up on the logging during dyno day it did not light a CEL it was just an internal code I think. The engine would literally be idling at 700RPM for 5 minutes then all of a sudden completely stall with no struggling etc. Sometimes it would do it withing a few minutes, sometimes it would idle fine for 10minutes then stall etc. I would have to turn ignition off and the back on to get the car to start again (if it did tbe stall sympton i couldnt restart it without restarting ecu) I have done a re calibration of the APS and TPS just now. The TPS still sits at around 8.4% when no foot on the throttle. Attached a new log but think that will show the same as the previous log. Should TPS Main be at 0% when no foot on accelerator pedal engine off. E throttle logging 2.pclr

    Altezza+ PNP 3sge e throttle issue

    Ok thanks will try again. So if the error accumulator reaches a certain amount (how many roughly is this?) Would this cause the 'rpm limit' limp mode you say rather than an e throttle error and CEL? Cheers Brendon

    Altezza+ PNP 3sge e throttle issue

    Hi there I have done a quick log with engine off. I have attached a file of my current tune/setup. Dont look at fuel numbers etc as on new injectors and a very base tune but that is not the issue. Was still doing the rpm limit stall on old tune (all other settings are the same). The quiet throttle option does stop the hum at key on engine off. Sorry dont know why log file shows different values, adjust it to ANV2, ANV3 for fps sub and main, and ANV5, ANV6 for tps sub and main and should show graph.

    Altezza+ PNP 3sge e throttle issue

    Hi guys Running a 3sge beams with turbo setup Recently the car had started to stall on idle randomly every so often. Hooked the laptop up and when it happens car is idling at 700rpm nicely and then drops dead. Comes up 'rpm limit' which i dont quite understand as only rpm limit is my redline etc (doesnt activate CEL) Then a few days ago throttle shut down and came up 'e throttle error' and CEL came on. Found that the drive cog on the main butterfly shaft that the e throttle motor spins had stripped 2 teeth and seized. I have fitted a second hand throttle and it still wines when engine off, and still has the same rpm limit stall issue when idling. Calibrates fine etc. Is this second hand unit on the way out?

    VVTI question Altezza

    Hi simon I have done the cam test as per your suggestion. On the exhaust cam test it comes back with a steady value of 51.1 degrees atdc. On my DI2 exhaust vvti setup the value in the box is currently 48degrees atdc. Inlet cam test measures steady value of 45.4 degrees atdc and under trigger 2 vvt value it it currently 44.5degrews atdc. So is the exhaust cam value slightly out? Would you recomend to change the exhaust value from 48 to 51.1? Would this make it track better etc. Thanks Brendon

    VVTI question Altezza

    hey awesome thanks brad, so your when your exhaust target is 0, your actual position of the eexhaust cam reaches 0? I see its currently very close at around 0.8 etc and follows very close all the way and returns back to 0. My exhaust vvti cam actual position never gets lower than -4.8 ie it never gets back to 0. Do you happen to know your exhaust vvti solenoid duty cycle value when the requested position is 0? Mine shows as 20% when requested position is 0. Still waiting for my original log but getting the feeling my exhaust cam is somehow not returning to the 0 position.

    VVTI question Altezza

    Hi rich, yes a few others believe it is all related, ie if my exhaust cam is not returning to the locked position or 0 at low down in the revs and kpa, then the exhaust cam is permanently retarded down low even though it should be off which affects my low down power and hence boost down low as well. Im also getting a bigger turbo, exhaust and manifold with external gate in a few months so trying to rule out a few more things before then. At that point the shop working on my car will check over the internals of the current turbo and do more leak down tests etc.

    VVTI question Altezza

    Hi guys, does anyone have a log file from an altezza 3sgebeams running the dual vvti, maybe a dyno session or road run so incan have a look at your vvti cam requestes position vs actual positions? Still trying to get to the bottom of this. Also have some movement sideways on my wastegate actuator flapper so may be a leak ther(not sealing properly), but would like to check some others logs to see what others same spec motors are doing etc before pulling off the dump pipe to have a look at the rear housing. Waiting on my tuner to send my original dyno log as well. Thanks

    VVTI question Altezza

    It starts alot better and idles more stable, drives perfect off boost but still tge same on boost. Almost feels like its missing the low down torque pull feeling it used to have. Will let my tuner know your feedback rich so thanks for that im leaning towards tubo just starting to wear out and loosing its puff. Was secind hand rebuilt when i got it 3 years ago so no idea of history or kms etc) The picture attached is fron the dyno day, the previous runs were my initial tune 3 years ago on 7psi spring with no boost solenoid, the last green line is current with boost solenoid to achieve the 9psi. See how much lower down it is initially, thats the loss of power feeling im meaning. Brendon

    VVTI question Altezza

    Did a compression test once it had warmed up, ResulResults were good so was hapoy with that! Cyl 1- 180psi Cyl 2- 180psi Cyl 3 -185psi Cyl 4 -182 psi The old plugs had been in for around 3 years thinking about it, done 30000kms on them (5 track days!)and had brown rings above the threaded part on the porcelain almost like compression lekage etc, fitted new plugs so will see how that goes dunno why i overlooked those...

    VVTI question Altezza

    Hi guys thanks for the info. I will do the plugs and compression test first to see how it goes. I have a new air filter and have cleaned the intake etc when i was fixing some small boost leaks around te plenum. The vvti solenoids have been replaced as well as the exhaust cam sensor so these are fine now. Also i change oil every 5000kms so the engine internally should be clean, always comes out a tad off golden. Engine has done 150000kms, turboed at 120000kms. Thanks for the input for the vvti settings and i see what you mean about the vvti table and kpa etc. Dont want to change any settings just yet as it was running fine on this before. So trying to get back to how it was etc. Brendon

    VVTI question Altezza

    Hi guys So I have an altezza with the 3sge beams, pnp g4 altezza link ecu and greddy tdo4 turbo kit. Was currently running on a turbosmart wastegate actuator with 7psi spring, tuned at 9.3psi for the last 3 years with no issues. (Was never sure how it managed this with no boost control on a 7psi spring but worked perfect) On my last track day the car suddenly dropped to 7psi boost and would not boost higher and felt sluggish. I initially though boost leak etc. Found a few and now passes boost leak test perfect. Fitted a new actuator spring and wired in a link boost solenoid. My tuner on the hub dyno however could not get the car to get up to its previous 172rwkw. even using the new boost solenoid, it could make 9.2psi but has lost around 20rwkw. he then noticed that the car wasnt responding much to timing changes where some runs would start off good and then drop out, or some runs would just not start off good at all even with no changes to the ecu. He was then thinking maybe sensors or vvti solenoids so I have changed all of these and still no change. Could it be a sign the turbo is just wearing out or something to do with my vvti system? turbo has been on for 3 years with around 5 track days and weekend driving 30,000kms. I have attached my tune file and a log file for a recent test drive logging the intake and exhaust cam positions and targets and solenoid duty cylces. Also a last question is the DI2 value (where the exhaust cam sensor is wired to) never illuminate green or says on when driving, just stays unlit and OFF. (ie the power steering DI1 will illuminate green and change to ON when turning). I have checked all sensor have ground and continuity back to the ecu input pins, and all 3 (crank, intake and exhaust cam sensors all have readings of 1.02 k ohms).Thanks Thanks Brendon Brendon original tune 5.0.3 01-10-16 (after launch control and cold tune start fixed) with boost solenoid settings.pclr vvt log drive.llg

    Toyota Altezza Throttle body issue

    Hi dave, pulled plenum off tonight and noticed a small line between the outside of the rubber and the plenum sections on runners two and tgree like it had a tiny leak, so I put sealant around all 4 runner holes, reinstalled the plenum and throttle body, refit all vac lines and it started perfect let it warm up on its own and it dropped down to 1100rpm and idled perfevt like it used to. So I believe the problem has been solved! ::D still cannot believe that it was a leak as all info pointed to a settings probelm until I tried the idle off and ethrottle off tonight which resulted in no change. So thanks to you guys I have learnt a lot about the software and my setup. Can never be too careful I guess.. as I followrd the toyota manual to a t and it specifically said no gasket was required on that particular part due to rubber interface.. so there ya go Will still be taking car to tuner on weekend to get cold start sorted a bit better, and also getting launch control setup as well, have jist obtained an expansion cable to add more inputs and outputs Will be sure to ask for help if I get stuck in the future!

    Toyota Altezza Throttle body issue

    Based in mt roskill, auckland, new zealand. I pulled the engine cover off and removed main breather hose with engine running, again increased with hole open and then blocked with thumb, dropped back to high bouncy idle of 3000rpm or so. Currently pulling it apart again. In terms of how aggressively I cleaned the tb, I merely sprayed degreser inside and then scubbed the walls witj toothbrush etc. And for plenum only pulled off main plenum that mounts to the rubber section, so thats the only seal I have technically broken, but like you said, I checked before reinstalling and it showed it didnt need a gasket in my engine manual.
