Message: [QUOTE="CATDiezel, post: 793825, member: 4387"] Split shot injection on a 7.3L or 6.0L is and was a completely different animal. Your talking about a sluggish responding heui injection event that was less than stellar for reactivity and precision. Could it be made to work... YES... But with very precise tuning and lots of cylinder pressure testing. Multi-shot injection has proven to make a better cleaner burn... Your looking more along the lines of PREHEATING the cylinder, which is a good thing for optimal burn rate and efficiency. So saying "I have lowered my EGT's" does not necessarily mean anything has been accomplished in the name of efficiency. In short... your better off KEEPING your multi-shot injection on a 6.4L and 6.7L and a 6.7L common rail cummins and duramax as well.. I tested these on a small mans scale sometime back with both the LBZ duramax and the 6.7L cummins. NO GOOD.... To sum this up: There is a fair amount of wasted fuel with a single shot event were you can stage the injection events and use the "same" amount of fuel but with more efficiency. Some of the benefits are a quieter running engine, however that was not the original goal... just a nice byproduct of the multi-shot.... plus it WAS for emissions but did not threaten a negative affect on HP or efficiency. EDIT: On a funnier note,,,,, I just realized I have already responded to this thread once or twice before.... WOOPS... Anyways.... LOL [/QUOTE]
