  1. Past hour
  2. Slight tweak to pic...
  3. Today
  4. Thanks for the feedback Adam, much appreciated. I did see the pic you mentioned and also saw the HPA webinar explaining about it which was very good. It took me a while to understand the various terms, hence I produced my pic to aid my understanding. Does my revised pic look correct now: Please could you also comment on my setup, screenshot and files attached. 682.llg 682.pclr
  5. Ok, I think you will be out of luck in that case, this is not an ecu I have seen before. Someone like wiring specialities may be able to make an adapter loom if the header plug is available.
  6. Yep, if you are using modelled mode then you will want the IAT trim table to be mostly zeros with just some trim in the top right corner.
  7. Yes, pretty much the same. The conditions for GP Outputs (used for the warning light) arent quite as complete in the G4 but you will be able to acheive something similar.
  8. Can i do the same thing with a link G4? regards!!!
  9. No it has a 64 pin plug/ 4separate plugs. The car is a factory 20e manual. The website only lists compatibility with the twin cam motors.
  10. Yesterday
  11. Its a GM sensor but stock location. The actual sensor tip does protrude into the manifold air path. I read about the IAT trim table in another post from awhile back. If i select this ON, would i start with zero'ing out the entire table and try adding some values in the 0% TPS / higher IAT areas first?
  12. So there should be no difference in that case if you are comparing a G4 to a G3 with G4 firmware running the same map. All the important hardware is the same between the G3 & G4.
  13. A single screenshot does not give anywhere near enough info. You need to post a copy of your tune and preferably a PC log of it on the limiter.
  14. Did you not see the picture below in the help file? Yours doesnt seem to show that there is no limiting below the control range and that the start cut is different for WOT than smaller throttle openings.
  15. Yes the shape will be similar but the numbers will likely be quite different. The fuel table will need to be re-tuned.
  16. The GTR IAT is not a great sensor, it is a solid brass sensor and doesnt protude much into the air stream so it is quite slow to respond. Many companies sell a replacement fast response sensor that extends further into the airflow which will help. Here is one example: http://www.nzefi.com/product/fast-response-iat-sensor-r32-34-skyline-gtr-specific/ The other thing you can do is set up your IAT trim table with TP on one axis, then at small throttle openings and high IAT's, you can add fuel (or remove less). You will notice our latest GTR base map is set up this way.
  17. The Hella SSR's are quoted as being suitable for PWM of inductive loads up to 1000Hz. I have used one at 1000Hz for fuel pump control before with no drama although it was a relatively small pump. I have been working with another guy recently that is using one to drive a large solenoid operated diesel fuel pump and his was getting very hot at 1000Hz, but dropped back to 500Hz and it is happy.
  18. Enter your base fuel pressure (actual running fuel rail pressure) and minimum effective pulse width in the Fuel Main screen. Next, Injector flow @ specified rated pressure( whatever is specified from manufacture) in the injector setup screen. Example, I use 315 kpa base fuel pressure and min effective pulse width of 0.2048 (entered in the Fuel Main screen). Then my injector flow is 1066cc/min @ 300kpa pressure (entered in the Injector setup screen) My ID injectors include injector flow data at multiple pressures, so I tend to use the one closest to my base fuel pressure. Dead times and minimum effective pulse widths is great data to enter as well if you have it.
  19. I have Bosch 2200cc injectors and I am setting up injectors for moddelled fuel. Do I set up as 2200cc?. My previous system was not desined for injectors so large so I had to set as smaller and adjust deadtimes to suit.
  20. I tried going with a higher value in the Post start enrichment % in the 70-90 degree ECT and longer post start decay time (20 seconds) to see if having the decay timing longer then my closed loop lambda timer lockout (18 seconds) It helped a little bit. Still went into a lean condition but for a shorter amount of time.
  21. So just a quick rundown, this is my first time getting a vehicle to start and run with a plug&play system. R32 GTR Rb26 itb engine setup. Any advice in general if you have the time to look it over would be great! Keep in mind, it has not been tuned by my tuner yet, I am strictly driving around under 4500 rpm and max roughly 60% throttle for break in and basically just learning how to set it up myself. So far I've been very successful and extremely happy with this ECU. One small problem I am having is this lean condition after hot startups. I understand it's probably from heat soak from fuel and stock location IAT sensor. It's quick and clears out once closed loop control comes into effect it seems. I tried some changes to the post-start enrichment and decay time but with little change. Cooler ECT it's not as bad. Thoughts here? apr19hotstart.llg apr17.pclr
  22. Hi My launch setting is 7200rpm and 0.6bar boost,, i would like to have 1.0bar at same launch rpm,how to write in launch control retard table? Right now this is the settings.
  23. Thanks for the reply, I found a 15A diode from back in the days I raced Rc-cars with brushed motors/esc, which I soldered into the circuit, and now it seems to work, at least for about 10 mins when I tested. The diode was warm, but was able to hold it. The same for the relay, warm, but able to hold it. Stable voltage output as well. I guess I must find a more suitable SSR, but have seen other people use the Hella SSR controlling fuel pump...
  24. Yes, it's exactly 100 Ohms, I will try a normal aux out, but at the moment while tuning I have the tacho turned off. We will turn it back on when we've finished tuning. Thanks.
  25. You can't pwm a fuel pump with a standard ssr, they are not able to drive an inductive load. You will need a fuel pump controller or a circuit designed to pwm inductive loads. Something like this would be suitable :- https://www.infineon.com/cms/en/product/power/smart-low-side-high-side-switches/automotive-smart-high-side-switch-profet/power-profet/bts50010-1tad/?redirId=103222
  26. Hi, I setup FP Speed to control my Walbro 525 lph in tank pump. I use a Hella 4RA 007 865-031 SSR relay. 1000 hz. Problem is when the car starts, it just take about 1 min, and the fuel pump starts to see lower voltage from the relay and the relay starts to gets to hot to touch... I believed there was something wrong with my fuel pump, drawing to much current, so I scoped it and it was only about 10-12A @ about 50% duty cycle... The relay is rated 18A. Should I use a different frequency and/or a flyback diode? Any idea what can cause this? Have I got a fake Hella relay? Looks legit with the Hella stamp and part#. See scope trace:
  27. The car was originally tuned with a g4 ecu then it got stolen from me. I had a g3 laying around so I decided to wire that in. Then I upgrade the g3 firmware then load my original g4 map in it.
  28. Sorry for the late reply and thank you for coming back to me. Can you outline the benefits of going to VE from traditional? I don't currently plan on running flex fuel, which is what I gather the main advantage would be? I had a fiddle and the fuel map seems to keep the profile from the traditional map, is this typically correct or will the VE map profile likely be quite different- I appreciate thats a subjective question, but generally speaking does it following the same sort of shape? Is there anything else to consider when deciding whether to use traditional or VE?
