edwin Posted October 11, 2010 Share Posted October 11, 2010 Hey Guys I'm killing my self with this prob. What else could it be. I did a z31 ecu swap and every thing looks to be connected correctly. Maf is talking to the ecu, idle is at 3200 rpm, I have spark, etc...I can find any leaks in the hose. But my plugs are still black and I lower my fpr to zero. and is still rich has ever. Does it matter the the fpr is at the end of the rail after the injectors or should I re-position them to go in front? Quote Link to comment Share on other sites More sharing options...

michaelp Posted October 11, 2010 Share Posted October 11, 2010 You cant run 370cc injectors on an ECU tuned for 260cc injectors... Quote Link to comment Share on other sites More sharing options...
S130Z Posted October 11, 2010 Share Posted October 11, 2010 How do you KNOW you are running too rich? Do you have a wideband? Quote Link to comment Share on other sites More sharing options...
michaelp Posted October 12, 2010 Share Posted October 12, 2010 FWIW, my Z31 always ran like 9.5:1 AFRs at WOT and 11psi of boost, on the stock tune. It idled around like 13.2:1 and 14:1. Plugs were ALWAYS black, but seem to last a long time regardless. I run .035" gap on them, in a VG30ET (9:1 compression) Quote Link to comment Share on other sites More sharing options...
