Guest 2jz240sx Posted April 18, 2008 Share Posted April 18, 2008 I have a tec II ecu on my 2jz with the stock 2jz rail/injectors/regulator. I am running batch fired alt for the injectors. I cannot get the idle a/f's any leaner then 11.5:1 When I take out any more fuel I reach the min injector time (1.25 ms) and the engine starts missing. I can't figure out how anyone can run larger injectors with the batch fired injection. I need to lower the fuel pressure at idle only. If I lower my base fuel pressure I will loose injector flow up top. Any ideas? Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted April 18, 2008 Share Posted April 18, 2008 Raise the idle with an IAC, or by cracking the throttle open. Lean it out, then pull timing to drop the revs. Mario Quote Link to comment Share on other sites More sharing options...
