Took the car out for its first drive since install and found that at 65 MPH cruise A/F was 14-15 at 1/2 throttle from a stop A/F goes from 14 down slowly to12.5 at 7000 rpm.At full throttle it does the same I do not here any pinging at any time. Is this normal A/F # 's it goes to the dyno on Sat .

 

UP top (6000+) you should be no more then 12 with stock internals. I dont think Technosquare has a map for FI, but there are choices like Apex-i SAFC II or more advanced Greddy e-Manage and as you know the tuning should be done on dyno only. Find a good tuner.

Im going to assume you have a Vortech SCer .Your cruising A/F is ok .Any time you are just cruising its going to read high .When you get into boost is when you will see it drop .The Vortech comes tuned real rich .So you should be safe .Your wideband isnt going to read it perfectly .Only way really to tell is to have it Dynoed .While you are there have it tuned .See if the shop has the R4 software first .If not call SpitSecond and order it $20 . Call 949-863-1359 .If your tuner has never used it...go to My350Z.com and do a search for R4 software...there are some things you will have to know before getting into it .SpitSecond is real helpful on the phone also...Good Luck

Couldnt afford it when young...gonna play when Im old
