the titan my be in need of ecu programmer or tuner tool, heard about venom making something. my cousin has a titan with exhaust and intake thats why im in these forums and i was thinking of trying to put a apexi afc on it to control the fuel.if i put the wide band in it now ill be able to see how the a/f is but havent tried it yet. i do some car tuning worked with some afcs and some stand alones and piggy backs. if the titan controls its fuel through the mass ull be able to tie the afc in and control the fuel at diff rpms and throttle posistions. put a wide band in and tune away maybe egt if u really want and street tune away. you should be able to figure it out when the venom is done if it ties into mass then the afc will work. i have a motec wide band lamda and access to a dyno even which doesnt mean much u can street tune just as well almost with those 2 parameters. if anyone has input let me know im about 2 try it on my cousins.

well form what I know about my last car that ran the new CAN protocall on the obd-II is that the system will let you tune ti but it will eventually learn the tuning and compensate for it to get back to stock parameters

Seadoo, you might want to try the search function. I seem to remember some threads here where guys were working through these same issues. No one was aware of a programmer for the engine and I seem to recall that there were some proprietary features which were hindering anyone from making much progress.

I certainly do hope you can come up with something though. A lot of people are waiting on a professional grade programmer.
