davidh Posted January 22, 2004 Share Posted January 22, 2004 well, im trying to decide on what combo to go with. i need some input on this guys so if ya could help me out id be very thankfull. i know that all you have to do is tune the carbs right and you got a pretty stout motor, but on the other hand if i were to go megasquirt i know i can tune the motor as well and tune it sharp! so my next question would be who would win in this battle between very well setup carbs, or a N/A FI megasquirt tuned to its finest?? might i add im using it for the daily driver/street so fuel mileage is at issue.

SleeperZ Posted January 22, 2004 Share Posted January 22, 2004 If fuel mileage is of concern, fuel injection wins every time. I get 27mpg cruising 85mph with my 300rwhp stock L28ET and a factory Z31 ECU. However that constantly corrects fuel mixture to stoich while cruising -- I don't know if you can tune a MS unit to do that. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted January 22, 2004 Share Posted January 22, 2004 MS unit uses the O2 sensor to correct fuel (run in closed loop mode) during cruising. Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 26, 2004 Share Posted January 26, 2004 and if you use the Techedge DIYWBO2 with the ability to set the switchpoint, you can have the O2 sensor correct to something much more mileage-friendly like 15.7:1 for some really impressive cruise mileage figures!
