I have a 2003 Z with a GReddy twin turbi kit on it. It has a factory ECU. Is there a company that re flashes factory ecu to run with a GReddy kit. I know Osiris does, but they won't ref lash my ecu. I have to take it to a tuner and have them do it.

Help!

 

now where is the question ???? I'm kinda lost... do you want anther type of reflash ...
or away to reflash the car with UPREV with out a tune....
plz clarify so someone could help you ???

oooh one more thing read throw posts and threads, search here and there in this forum,
you will find a lot of answers...

 

Sounds like op was an off the shelf tune?

Negative. Go to a protuner and have them tune it properly with osiris.

 

I am looking from a company I can just send my factory ecu in to get re flased. I'm in the racing capital of the world, and no pro tuner in this state.

 

You don't send your ECU in you can get a reflash emailed to you, not sure who would do it though. Most tuners won't want to because if they email you a tune for a car they have never seen and it blows up it looks bad on them. Shops to talk to would be GTM, Forged, Dynosity, Church auto or pretty much any other tuner on The Osiris list of tuners those are just 3 shops that would have a base tune for sure. To be safe you will need to get your car tuned though. You can even buy an Osiris license and tune it yourself or take it to any tuner in your area to get it tuned.

 

I wonder if any of them would send me a base tune so I can drive my Z to them? Dynosty quoted me a worse case scenario, but need the car. I haven't talked to them about a base tune though.

 

If you are close stick with them, I have heard tons of good stuff about Hal. I would talk to him about the base tune.

 

I will call them tomorrow. Thanks.

 

im guessing you bought your car already booseted?

 

Not sure I understand what you are saying.

In order to function the GReddy TT must use either a piggyback to assist the stock ECU or standalone engine control unit that replaces the stock ECU. Either set-up would have to be "tuned" after installation. As far as I know reflashing the stock ECU is usually done with N/A mods not forced induction.

 

Not for this application. For the vq platform you can run UPREV on a boosted kits. the only thing that will be limited is the boost control access. you will be tuned on the MAF. simple and easy solution for basic builds.

 

i ran my built stroked boosted z on just osiris and it worked great, was making 670/699 whp tq. its all in the tuner

 

You can drive to any tuner...just dont get into any boost and you will be fine.

 

True, but to the stock ECU with a tune you don't have enough control over what is happening while you run your 670 horses hard. Plus no launch control "I know that can be added as an external device", knock amp, wide-band control, and stuff like that...

you can be fine with uprev but not for too long. I'm running uprev on my build right now but I'm about to switch to haltech sometime soon....

 

We are in Louisville, KY - only about 100 miles south of you on I65. Come on down and we will get you straightened out!

 

Your only a couple hours away from Dynosity I wish guys in my area talk about flying Hal up here to get thier cars tuned. Get your car down there it will be well worth the trip to get your car properly tuned by an expert.
