  2. CAN Lambda Error 54 Excess pump current

    in G4+

    Posted

    Hi All. 

     I have experienced  this error, the sensor would have covered around 5000kms.

    Is there anything that can be done to prevent it? Is it the sensor at fault or the unit?

    I have a relay & power is drawn from the battery, I don't have the capacitor. 

    Appreciate the assistance. 

    Thanks

  5. Supra JZA80 NA-T lean and stalling

    in G4+

    The factory fuel pump controller is a PWM input speed control unit. Runs 9V on idle & switches to 12V under load conditions.
    The general consensus is that it runs fine on a Walbro 255, with a 450 it cannot handle the current & cause stalling.

    I ran my car with a stock fuel system & Link with the three stage PWM setting, worked fine. 

    I tried a Jag/Ford/Continental style controller but had issues (was a 2nd hand unit, most likely was not working well), so as Adam suggested used a normal relay, working fine.

    To the OP, maybe swap the Aux 2 to FP speed & Speed control method to the 3 stage PWM & see if it works. But if you have a high current draw pump, best to use a relay.

    But in Durban, I heard Steve at Dezzi was great for tunes. Was thinking of sending my car there if I don't come right in Joburg

    He is, but is so busy, there is a waiting period. Also, he is down south in Margate, so bit of a drive from Durban, about 1.5hrs away. Not the most convenient if any adjustments to be made.

    I ended up tuning my car myself, busy with a fuel system upgrade then will do a final dyno.

    I'm having the same issue with the normalise on, will try with the normalise off.

    Did you come right with yours?

    Thanks, I'll give it another try without normalizing the gear ratio.

     

  13. 2JZ Idle Fluctuation

    in G4+

    Posted

    Hi guys.

    Been getting some strange behaviour on the Supralink & OEM IACV setup I have on my Supra.

    It was overshooting on cold start to around 2000rpm, I adjusted the base position & changed the min clamp, it has improved to the condition in the attached log.

    The next issue is a drop in idle base position, then a spike to 2000rpm about 20 seconds into the log. 

    I suspect the valve may be faulty, but want to confirm the settings I have make sense before changing anything.

    Tune & log attached.

    Thanks.

    Hi Mate,

    It seems to be set up correctly to me and appears to work correctly and switch the TC table when I generate a CAN signal that emulates what I expect the keypad to be sending.   

    Here is a quick video showing me testing:  https://1drv.ms/u/s!AiYbYlZQuRHPsHxSiejfbxtxaDgJ?e=CyFFHG

    THanks Adam for the detailed check.

    I had forgotten that the RPM, TP & speed lockout for the TC is set to zero in that file. Sorry about that.

    If I turn one of those on, the TC table cannot switch.

    Its not a big issue, but just checking if that is the way the it should be?

    Thanks again.

    @Samuarai Supra 

    if iam right do you use the Toucan Display Keypad function without a PDM ?
     

    Yes, thats correct, no PDM. 

    @Adam, 

    Tim from JTI helped me sort out the setup, I understnad now that the DI's being repeated in the stream 2& 3 was the issue. 

    What I'm confused about is how the logging worked being duplicated.

    The table switching does not work with any of the lockouts being enabled, any idea on that.

    I had not assigned any CAL's as yet till I complete my water meth setup, for which I was going to use correction tables against a DI from the meth system.

    If not using this, think CAL 1 would be base tune, 95 octane & low boost and CAL 2 hi octane, high boost and timing.

    But none of that has been setup as yet, so was not expecting any repeats. 

    Buttons are 1, 2, 3 for logging, trac disable and trac table switch.

    I had looked through the file, couldnt find any repeats on the DI's, where had these been?

    I followed the manuals as much as I could, strange thing is the logging button works fine.

    Thanks Adam.

    Edit: 

    Read your reply again Adam, are you saying the CAN DI's on 1501 are only for use on the CAL funtionality?

    The keypad setup on stream 3 is as per the keypad manual, my understanding is that those CAN DI's can be used to switch functions on the keypad as well.

    Thats how I set the logging function up and it works fine.

    I attached the manual I used as well.

    Hi.

    I have an issue setting up my toucan keypad with the traction disable switch & slip table 2 activation.

    I have assigned a CAN DI to the table switching, but it does not seem to communicate at all. 

    The traction disable has the same issue, not switching on or off using the traction disable switch status parameter.

    I have used  the exact setup for the internal logging which works perfect, hence I'm a bit unsure on what the issue could be.

    Attached the tune for reference, hope some can help, pretty new to CAN setups.

    Note, the launch control is also activated by the Toucan via a CAN DI and works fine.

    Thanks.

    Hi Samurai Supra,

    Have you found the solution of your problem ? Can you tell me the path you finally use ? Did you tried the idea of the Mike2J ? 

     

    Thanks for your answer

    Sorry for the late reply, used Mikes idea, ditched the EVAP, car is running fine.

  23. Fuel pump doesn't stop priming

    in G4+

    Not 100% sure. My guess is as long as there is enough fuel pressure to not run the engine lean at the lower duty cycle, it should be fine. 

    I would check it anyway to be sure.

    Maybe some more experienced mappers can comment?

    Is the stock fuel pump ecu still in place?

    Have you loaded the Link Base map?

    If so, the fuel pump control is set to General Xover.

    Change it to 80hz 33/66/100%DC. To use this, the Aux output to the fuel pump should be set to FP speed.

    This is three stage PWM control which according to the help file is the correct setting for the Supra.

    I had the same issue on my Supralink, the above solved it.

    No. Level was good. 

    Hook it up to a laptop and download the NCH software.

    Make sure its charged if you havent.  Maybe thats your problem ?

    I find it that 1/4 turn on the gain is just the right level in my laptop without clipping the audio. 

    I did charge it, maybe it was not fully charged, will put it on again.

    Will try the laptop and a new set of headphones.

    Thanks mate

    You need to use head phones that have a 3 pole 3.5mm jack, often referred to as stereo.  Most smartphone earbuds have a 4 pole plug as they also have a microphone, these won’t work.

    Thanks Adam, makes sense.
    Will go get a new pair..
