  1. FL5 Overheated on Track

    ItĀ“s very doable, the code is there. Just need to borrow the sensor from an FK2, pin it on your ecu and do a few software changes. I have the software part of the solution ready to test, just didnĀ“t have the time or the will to do the other part. You are correct. The system is built to warm up...
  2. FL5 Overheated on Track

    Well, yes, most of the flow go trough the radiator but the amount that circulate the parallel systems is not negletable. Anyone who turned on the heater at the track will know what I meanā€¦ it makes a HUGE difference on temperature, in my case its the only way to do 2 full laps.
  3. FL5 Overheated on Track

    Yes, but this is the one we cant get rid of. Itā€™s importat to bleed the air from the system.
  4. FL5 Overheated on Track

    The hot water comes out of the head, then it has 5 possible paths: To the radiator, then back to the engine To the turbo, then back to the engine To the transmission, then back to the engine To the heater core, then back to the engine To the throttle body then back to the engine. See that...
  5. Limp Mode on first track day

    Are you kidding me? even if no limp mode occurs, how long do you think the engine will last if you keep driving with head temps over 120C?
  6. FL5 Overheated on Track

    car limps over 120C, sometimes it goes all the way to 125 then limps. but keep in mind, anything over 100 is bad. 110 is as far as I would consider acceptable. These cars have many design flaws that lead to overheating. Keep in mind car manufacturers are more interested in making the engine...
  7. FL5 Overheated on Track

    I have some spare time this week, so IĀ“m builing another radiator to fit behind the intercooler. But when I stop to think about this, it pisses me off that is so hard to cool down a car that shouldnĀ“t have this problem to begin with. I ordered the hondata fuel kit also so I can run at least...
  8. FL5 Overheated on Track

    I havenĀ“t tested the latest setup at the track, but another addition I made, other then the PWR and the HEL oil cooler, was divorcing the transmission from the water system. Main reason for that is to remove parallel systems. Keep in mind that if you plug all parallel systems and still run a...
  9. FL5 Overheated on Track

    well.. I donĀ“t have data but IĀ“ve had multiple turbo cars and never ran a water line. never had issues. EGTĀ“s on our cars are low due to the headifold and I also run a lot of fuel so it might live. Just avoid shuting the engine down imeadiately after beating the hell out of it and it should...
  10. FL5 Overheated on Track

    Remove the water lines that cool the turbo. We tested it. great improvement
  11. Anyone using RZCREW intake manifold?

    I even asked them, and yes, IĀ“m the only and first one lol. should take like 45 days to arive then IĀ“ll do the testing
  12. Anyone using RZCREW intake manifold?

    It seems like everyone is running the pracworks manifold, including many friends of mine, but I refuse to pay 2K$ on it and I really dislike the 180 bend on the runners. So after some research I found this...
  13. Low Turbo Pressure as a Result of Tuning

    a drop in filter should not cause problems. The downpipe could get boost control off but IĀ“ve never seen it on keihins
  14. Low Turbo Pressure as a Result of Tuning

    If the maf sensor housing is changed on your intake then it could be a problem as well
  15. Trans Fluid - when to replace?

    I like the video, but I disagree on loosing torque from the extensions. Unless your arm is an impact wrench lol
  16. Trans Fluid - when to replace?

    a little overfill in the transmission wont hurt
  17. Low Turbo Pressure as a Result of Tuning

    I sent you a PM with my contact info, but you could also upload it here I donĀ“t see why not
  18. Low Turbo Pressure as a Result of Tuning

    The 1.5L ecu is a bit tricky to work with, 99% of the tuners have no idea where to start so IĀ“m not surprised. The transmission can also be in the way but there are ways around it. I donĀ“t have the 2022 1.5T in my market so IĀ“m not sure wether itĀ“s more complicated then the 10th gen but send me...
  19. An in-depth talk about FL5 ECU tuning

    that never crossed my mind lol. btw, testing flatshift last night and setting some base 100-200kph times on a friendĀ“s car this tune is our base for trackdays, will probably push 30psi on a street tune to see if it can get to mid to high 7Ā“s Also maybe 100rpm more and we could do it with...
