I have searched and only found one thread on here bout swapping a 350z or another g35 ecu. The thread said it can't be done!!?? Does anyone know exactly why?

I'm a little on the fence bout getting a reflash cause my experience with Hondas was not very good! basically higher rev limiter and s**t ton of gas throwin in the mix and presto you have a smokey gas guzzlin machine from running way to rich!

 

What are you asking? Reflashing is not the same as swapping ECUs. If you're thinking swapping a Z ecu into a G is going to net you something (if it even where possible), it won't.

UpRev Osiris is where the best reflashes are coming from. But if you have a doggy door G35, you are probably screwed.

If yes, then the reflash you want is the TechnoSquare mail in ECU option.

 

What is the cutoff date for the ecu reflash? I have a non doggy door 04 built 11/03. Is there a way to check? Vin?

 

04 should be good to go. Even later build dated 03s are okay.

 

Good I was stressed. I'm finishing up my bolt ons this month and I want to get a reflash before the sept socal meet

 

Now just to clarify, I don't need to purchase any hardware. What all do I need? E tune?

 

Why can't doggy doors be reflashed?

 

They all can one way or another. But not all can via UpRev

 

Excuse the stupid questions but what is a doggy door?

 

 

Doggy door - 2003 style trunk lid

 

I have a 2003 "doggy door"

I'm in the process of wiring up a Greddy Emanage piggy-back to control A/F and ignition timing and what not.

 

That's definately cool on a diy and grassroots level of modification I like to see. I hope it works out. The thing is you still have to get to a dyno to tune or hook up a wideband if you want to datalog via another obdII scanner type thing and tune yourself. I briefly looked into trying to patch something in also. Either by hardwiring like you're doing or using a maxima patch harness for an Utec. But from what I read, piggy backs always fight the oem a/f and ignition timing tables and only affect open looped settings. Also with these things, you can't resolve the TB opening, e-wire map (sprintboost effect), rev limiter and more importantly ign and a/f targets.

As much as a pain it is, I'm going to send my ecu in to TS. Only question is should I get a set of high flow cats or not. Because if I do, I'd get them installed before having the ecu modded. And probably get to a dyno for an ign/air fuel datalog so TS could flash based on that.

 

The people who have reflashed......Have you guys noticed a massive decline in fuel economy?

 

See that search button? It is not just for show there are a lot of threads on this
