MidnightRider Posted February 28, 2012 Share Posted February 28, 2012 Is this mod possible to do with the stock 280z L28E ECU and fuel injection system? Or do I need to run an aftermarket ECU to change the air/fuel ratio? Quote Link to comment Share on other sites More sharing options...
FricFrac Posted February 28, 2012 Share Posted February 28, 2012 Anything is possible... I guess you could reduce the fuel pressure so that the turbo injectors would deliver the equivalent fuel as the NA injectors. I'm just wondering why you would want to do that?

MidnightRider Posted February 29, 2012 Author Share Posted February 29, 2012 I wouldn't. That would defeat the purpose of delivering more fuel. Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 29, 2012 Share Posted February 29, 2012 (edited) I've also suggested dropping fuel pressure to allow using a high capacity injector, in the past. It was pointed out by a knowledgable Hybridz member that at low pressure you might lose fuel atomization. If you go too low on pressure, you'll get a dribble instead of a spray. That would be bad.

billseph Posted February 29, 2012 Share Posted February 29, 2012 So why so you need/want more fuel?? Obviously since the turbo injectors supply more fuel than n/a injectors at any given pressure you will be running "richer" across the RPM scale with turbo injectors and a stock n/a ECU.

NewZed Posted February 29, 2012 Share Posted February 29, 2012 Maybe he's just trying to save a few dollars on injectors... Quote Link to comment Share on other sites More sharing options...
MidnightRider Posted February 29, 2012 Author Share Posted February 29, 2012 Never mind, I'm going to upgrade to megasquirt in the near future. Quote Link to comment Share on other sites More sharing options...
