i have a titan engine harness and ecu.
ecu is brand new and ready for any truck with flex fuel you want to throw in with it, and the harness is for a 2wd truck.

harness is 150$
ecu 100$

200$ package deal, buyer pays shipping.
the harness is kinda big, but not really heavy. shipping quotes on request.

this is perfect for anyone who is getting ready to vk their frontier.
any questions let me know, ill answer to the best of my knowledge.

This may be kind of a dumb question but what differences exactly are there in the flexfuel ecu and engine as opposed to the regular 87 oct and up ecu and engine? Obviously the power, internals and all that's the same.

the only differences i could confirm on the engine is larger injectors. beyond that i have no idea.

on the ecu, i seriously doubt there is a difference. the ecu is ready to be registered for really any motor i believe. the ecu i have in my truck right now is for a 4x4 none flex titan so i really dont know what the difference if there is any. 4x4 is controlled via bcm but routes through the engine harness. thats where a lot of people were pulling that it was through ecu, so you have to get the right ecu. but thats false anyway.

Does the ECU have a key for the ignition or what?
i got it BRAND new, when i bought my motor a little over a year ago now, they lost the ecu that went with it, or damaged it. they told me they lost it. so they sent me a brand spankin new one.

the key for the ignition bit, is tricky. if you have nissan handy, having no key is no problem, they can register your key in 30 seconds. thats what they did for me. on another hand however, you need the old key for the ecu, and your new one. and there is a sequence of offs and ons to do so your original key will work.
since this is an ecu without a vin or a truck, it can be thrown and registered to whatever you want, but it never had a key at all.

Quick question. Why didn't you just buy the same engine trans and harness and ecu from the same truck? Seems easyer that way. And I will be doing this swap this summer. And keeping the turbo
