Purpleline Posted November 23, 2018 Report Share Posted November 23, 2018 Hi, After 10months.. i finally installed the g4+ into my ecr33. Everything start to put together and working step by step. Im wondering how u can limit the boost to stay not go over 0bar just like the factory ecu under no load. When i rev engine up with car sit still. Boost can go all the way to 0.9.. which setting i should be looking for. Tks Quote Link to comment Share on other sites More sharing options...
Richard Hill Posted November 23, 2018 Report Share Posted November 23, 2018 Remove the boost hose in to the intake. HTH, Richard. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted November 23, 2018 Report Share Posted November 23, 2018 There is no possible way you are making 0.9bar positive pressure just sitting still and revving the engine unless the tuning/build is diabolically bad, or you're running massive anti-lag or something. Both will be harmful. Normal running engines DO NOT make boost with no load on the engine. Quote Link to comment Share on other sites More sharing options...
neil brown Posted November 23, 2018 Report Share Posted November 23, 2018 I can make 5 psi of boost on revving engine on my ej20 Subaru engine with a gt2860rs turbo while stationary it is possible Quote Link to comment Share on other sites More sharing options...
Purpleline Posted November 23, 2018 Author Report Share Posted November 23, 2018 Yes.. thats why i think it is so weird. It ran on base map only...... not touching other yet.. 20181123_181206_1.mp4 You can see the mfd and greddy gauge both read the same which it must be right. Yes, it is making very high boost sitting still Quote Link to comment Share on other sites More sharing options...

Obviously no electronics can reduce the boost below whatever value the wastegate spring opens at. You will get whatever the engine airflow is capable of producing. If you think you have more boost coming in lower RPM than it used too then it is possibly too retarded or lean? Quote Link to comment Share on other sites More sharing options...

Thats what the dealer here said too. It could be a thing that mean my turbo flow quick. Or too much retard on base map. Im now setting the MAP limit as suggested by the dealer here t0 220kpa so i wont blow my engine for 1 st run. I only started the car but not driving it on road yet. Still need to activate other function like the knock etc. Tks..you guys are helpful Now looking around the NVSC setting. Found other post about a GP output but not select fm here Edited November 24, 2018 by Purpleline Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 24, 2018 Report Share Posted November 24, 2018 If you are using our plug-in ECU then the cam solenoid is connected to Aux 1. Set up like this: Quote Link to comment Share on other sites More sharing options...

Purpleline Posted November 24, 2018 Author Report Share Posted November 24, 2018 Fm. 1400 to 5800rpm Most are working good now except the hard start. Im wondering if thats something to do with the fuel master ms. No matter how i adjust those cold start,.warm.up.acc opening duty.. it doesnt make much improvement at all. I have stock injector 370cc. Fuel Master is now set to 9ms. The er34 gtt base mao has 11 which i tried b4 and it run very rich so i step back to 9. The orignal base map is 7ms which is way off as thats for a rb26 with 444cc. Any idea which i should relooking at? Possible put back 11ms? And them mass lowering fuel table will fix?? Quote Link to comment Share on other sites More sharing options...

Purpleline Posted November 25, 2018 Author Report Share Posted November 25, 2018 (edited) Im wondering why not build a base map download page so ppls can share their mapping? This will help alot rather than playing around aged base map in the package..... ecr33v5.3 2nd street tune coldstart.pclr Edited November 25, 2018 by Purpleline added final map Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted November 25, 2018 Report Share Posted November 25, 2018 A base map is there to start the engine to allow it to be tuned. Which it seems did apply here ? Trying to copy other peoples maps in the hope they might do something for you, is dangerous. Have the engine tuned properly by a competent person otherwise you risk damage.

Purpleline Posted November 25, 2018 Author Report Share Posted November 25, 2018 I was wondering a list with basic spec for the sample. It will be closer to start with. The gts-gtr base map provided just way off too much to use for a rb25. The one for er34 gtt is closer. Hoping that a seperated rb25det base map there will be great.
