  1. Thanks mate. I found this article, based on it, I think I have 2 issues, sensor is more than 1m away from the engine & turbo seals are worn. These will be remedied soon, going single turbo.. Hope I don't kill another sensor till then. https://www.nzefi.com/bosch-lsu-wide-band-airfuel-ratio-lambda-sensors-fail-often-aftermarket-performance-applications/
  2. 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
  3. SHouldn't be giving issues with current draw, unless its running out of fuel pressure for your setup.
  4. Parts EPC shows the same ECU in the TT and NA. My tune had polarity set to high, was working fine. What pump do you have?
  5. 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.
  6. 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.
  7. I'm having the same issue with the normalise on, will try with the normalise off. Did you come right with yours?
  8. Hi Adam, getting to target around 2 -3 secs after startup after adjusting min clamp to 50. I'm happy with that setup, will leave it as is. Thanks for the assistance.
  9. Thanks Adam, will give it a shot.
  10. Very quick start, only like one crank and she fired up. No overshoot present. NUR13253 Tune 202000513.pclr Log 2020-05-14 8;11;03 pm.llg
  11. Hi Adam, Updated the firmware, seeing some better behaviour on cold idle. Think I may need to retune the low temp base position, but before I do anything rather you take a look. Latest tune & log attached. Thanks. Log 2020-05-13 7;30;12 pm.llg NUR13253 Tune 202000513.pclr
  12. Thanks Adam, will do that update and report back.
  13. 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.
