I was wondering about the stage zero Vishnu Reprogrammed ECU upgrade. The site mentions that for $345, you can get the " XEDE User-Tunable Engine Control Computer". But does this inlude the items that come with the XEDE when purchased alone:
-Includes XEDE computer, Plug-In Harness, XMAP Tuning Software and 6' Serial cable
-XMAP Full-Functional Tuning Software
I was also wondering why you would need the ECU Reprogrammed since you could use the XEDE to tune your ECU to the stage zero?

 

Hi there-- As per:

http://www.vishnutuning.com/impreza_sti_stage0_v340.htm

The price of the reprogrammed ECU/Stg subzero for the STi is $750. For $245 extra, you can *substitute* the reflash for the XEDE. Not add it on The XEDE comes with a plug-in harness, serial cable and software (downloadable off our website at:

Lemme know if you have any more questions

Thanks for the reply, but I am a bit confused.

Maybe I am a bit confused, so if you get the XEDE, you no londer need the "reflash" because with the XEDE system you can flash your own ECU. If this is the case, why would you need the "reprogrammed ECU"? It just seems like you'd only need the XEDE since with that you can program your own ECU. I guess my question is, what
does the "reprogrammed ECU" give you that the XEDE doesn't?

 

I think the XEDE is a stand alone piggy back device that works with your ECU. I'm not 100% sure, but with XEDE your ECU is untampered. Please clarify if im mistaken..

 

XEDE is not used to reflash. XEDE is as piggy back. Stand alone is a term used for a system that replaces the factory ECU. Great thing about the XEDE is that you retain all the factory ECU safe guards. Xede gives the tuner the ability to tune with a higher degree of precision. Also, you can load a second map for race gas and have access to it by the flip of a switch or the connecting of two wires.

both will give you great results, but if you think you will continue upgrades past the sub-zero, i would go with the Xede.

Ok, I understand that the XEDE is a piggy back, and you can tune your ecu with it, which is really what I want. But why would you need the re-flash if you have the XEDE, I think that is where I am confused?

 

make it easy. Pick one:

reflash: no additional hardware needed, but no user end tuning. Once it's flashed nothing can be changed

Xede: hardware & possible wire in if no harness available, user tuning using Xmap

to answer your question, do dont need a reflash if your using an Xede.

 

Ok, that is what I thought, then why on the site is the XEDE an add on to the re-flash? Wouldn't you just want one or the other, but not both?

 

Power-Adding Options:
XEDE User-Tunable Engine Control Computer
Adding the plug-and-play XEDE to any of our power packages not only provides you the ability to custom tune your own car, it also allows to you to toggle between two calibration files. This means that you can upload a standard driving file as well as valet file. Or a drag race file and a road race file. Or a pump gas file and a high octane race gas file. When running 100+ octane race gas, activating the race gas file rewards you with an additional 20-30 wheel horsepower by a simple flip of a switch. The XEDE also additional output drivers for secondary injector control, intercooler water spray, methanol injection, etc.

doesnt say add on site. Go with the XEDE! you wont be disapointed!

 

Shiv from Vishnu explained it in the first response:

You only get one or the other. Either you get the re-flash or for an extra $245 you substitute the re-flash for the flexiblity of XEDE. It's very simple.

 

Right.. *substitute*, hhehe.. my grasp of the english language is not very goods. This all makes sense to me now. thanks...

 

hey, I have the plug-in harness XEDE and I never knew there was a switch to flip between 91 and 100 maps????

you need to have vishnu hook up the wire to access that map bank in the xede. Did you get a race map tune?

 

Is the stock ECU left untampered with XEDE? If your car only had XEDE, would it be save to assume you car's programming would be 100% stock if you simply unplugged the plug and play XEDE for dealer visits?

 

Right, there is no reflash with XEDE. It's a piggyback setup. You could use the switch and have (1) be the Vishnu Staged map and (2) be the blank map...or no intercept from the XEDE unit. So it would act as stock without having to unplug anything.

Just a thought.
