Not at all. Once T8 (the engine management system) decides you are outside parameters it will adjust other parameters to compensate.kay310 said:ok so how much boost can we play around with until the ecm goes nuttz?
Nothing i have been able to do has fooled the ecu to do anything. I have adjusted the actuator, tried a manual boost controller, plainly leaked vacuum pressure, mixed fuel, changed intakes, that is pretty much it. Nothing yielded any positive results at all.ctrlz said:The system is designed to run rich under load. If you add more air mass (by increasing boost) you will get to the point where the ECM cannot inject enough fuel. At that point it throws an error. It actually tries to find ways to limit the air mass before it ever gets to that point.
You can conceivably fool the ECM in certain ways which will allow you to run lean under load, but this risks serious engine damage.
Ok thanks for the info...So if i get let say bsr stage1...do i have to retune the ecm if i want to upgrade to a stage3? or i can just get the stage1 and put full exhaust, injectors and etc. without buying the stage3??Frosty288 said:Oh the new ECM will add tons more boost. The thing is you can't do it yourself. Anything you try and do without tuning the ECU, won't work.
If you change injectors your fuel metering will all be overrich. You have to have proper ECM programming if you change injectors.kay310 said:or i can just get the stage1 and put full exhaust, injectors and etc. without buying the stage3??
