Naturally aspirated please.

Thanks for coordinating this for us John.

Feather-
Would the tranny aspect of the upgrade be applicable to naturally aspirarated vx's...? Thanks

[Sheik-YurBooty]

without any doubts, count me in on the naturally aspired version., even though in the near future I plan on Tones SC. My question is what happens with the naturally aspired version once I install the SC ?...Either way, I still want the naturally aspired version.....thx, & by the way, GOOD JOB Oops! I meant naturally aspirated.

The design criteria is: to plug into the OBDII test plug, download and restore the stock program repeatedly; be able to upload and retract 3 (ea.) modified programs into the ECU.

Forgive me my ignorance, but it all sounds like russian to me..
Can somebody explain me what this is all about,
1-what is it
2-can you do it yourself
3-what does it look like/is it big heavy
4-any negative aspects

Sincerely,
your Dutch friend

1-what is it

its the cars computer.

2-can you do it yourself

after the modifications you just plug it back in.

3-what does it look like/is it big heavy

its a metal square or rectangle probably weights under 10lbs.

4-any negative aspects

u have to pay.

it's a tool for modifying the cars computer program

the only time you plug it back in is when you want to change settings or programs


its a metal square or rectangle probably weights under 10lbs.
about twice the size of a TV remote with a cable/cord attached, weighs about 2-1/2 pounds.

Holy !@#$%^&*!!!

This what I've been waiting for.

I'm in! I'm in! I'm in!;eekr;

I am voting for the full power option including ECU modification, installing supercharger, and tranny kit!!!

I have not purchased the SC because I was looking for a little more oomph if you know what I mean. This really gives me hope.

Long live the VX!

John,

What does the tyranny kit involve???

[SGT.BATGUANO]

I believe THAT kit includes 1 tyrant!

[Doc4h]

If it does what you say in terms of performance gain I'm in for the non-sc version. As a few others have said in one was to upgrade to SC would it be able to program for both? or would one need to buy the SC version?

Don't know!! Have to check with my local tyranny wizard.

We have to determine how much the box is capable of and then figure out how to get it through the shafts.

If we only need to wave the electrical wand I'm sure that will be in the program where needed.

May need to add disks and HD bands to the clutch pack we'll figure that out.

We do have a tranny available for modding.

Stay tuned.

I realize this may difficult, but as this project gets better defined, can youprovide more detail between the modes? It sounds like most people are interested in the performance mode, but I wouldalsolike to know more about the other modes. For example, approx. what percent improvement to you expect in fuel economy for the 'economy' mode. Also, what is the 'tow/haul' mode buy you over the standard factory load? Etc.

[WormGod]

What would be nice is to incorporate the abilities of the Interceptor that Tone offers into it. Just a thought, if that is possible.

With all of these sweet mods out now (soon to be this one hopefully), I think I will finally just kiss my warranty goodbye and go for broke. I am missing too much fun it seems.

No data available for the VX, however, on the 5.3L V8 in the GM trucks there were minor performance gains and an increase of 3mpg fuel mileage. (that would have been close to 20% on my vehicle from stock)

Also, what is the 'tow/haul' mode buy you over the standard factory load?

in the `tow/haul' mode the bulk of the performance gaines are concentrated between 1000 and 4000 rpm, vs performance where the gaines are maximized between 4000 and WOT.

Etc.

[Hotsauce]

I don't quite understand the need for economy/performance mode, are they not the same tuning? Both economy and performance tuning should be more timing, and mixture as lean as it can go without getting EGT's too high, or seeing knock.

The performance adjustments shouold be at a higher load and TPS, and the economy should be at a lower point on the map.

That way, if you want economy, just don't gas it hard, and max performance is always available by stomping on it.

I could understand if the different maps were for using different grades of gas, but otherwise I don't get it. Am I missing something basic here in tuning theory?
