ECU remap, nitrous, & supercharger

[Chicane]

I thought the engine (in stock form) ran a little bit RICH, hence the piss poor mileage, and black soot on the exhaust tips....

??

It runs lean in stock form???

Also, here's a page on how to read your plugs:

I suppose it depends on your definition of lean. It seems to run right around stoichiometric from 14.2 to 14.9. Best performance on a naturally aspirated engine is usually around 12.9. I ran a chip I set to right around that earlier and it made a great improvement removing all that "lag" we often feel. The fuel maps subaru used on the us model seem to be optimized for emissions.

Longassname, I know I'm not alone in saying this - don't forget the OBDII cars!!!! We want your chip too!!!

and i used to complain that i didnt have obdII.....not anymore

[TomsSVX]

lets see some charts, and are you selling this kit for a while or is it a one time deal?? because i would lvoe to have this in the future but other repairs and mods need to be done. also don't forget to mention to these guys that an exhaust is recommended

Yes the dyno plots are coming...after we go to the dyno
I suppose that depends how quickly we go out of business
These particular guys have been reading the thread for quite a while now I think

PS every one who hasn't been reading along...exhaust mods aren't recomended they are required. For stage 2 the primary cats must go.

[TomsSVX]

thnx a lot i hope to pic up your stage 2 withing 2 months or so

When's all this stuff going to be for sale?

As soon as I get back from the dyno...later this week.

[svxhunter]

There are probably others, like me, who have been reading along intently since the beginning and are very interested, as well as probable customers. Just haven't had much to say. If your making a list, add my name.

[lhopp77]

Watching and reading with interest.

Reading out of couriosity... I may be up for the Stage 1... But like everyone, I would like to see Dyno Graphs before I say for sure...

For your valiant efforts to create an attractive aftermarket for the SVX, I do hope that you stay in business.

BTW - I performed a few 0-60 estimation calculations for the SVX (assuming stock curb weight of 1623.85kg, and a 6% margin for error in the calcuations).

Stock AWD SVX - 230hp: 0-60 in 7.40 seconds (close enough to actual).

AWD SVX w/ stage 2 (assuming a 130hp gain at the flywheel with NOS) - 360hp: 0-60 in 4.73 seconds (obviously a little extreme).

AWD SVX w/ stage 3 (assuming a 40% power gain at the flywheel, as discussed earlier in this thread) - 322hp: 0-60 in 5.29 seconds (perhaps slightly extreme, but feasible).

I know someone will try to castrate me for these numbers, but they are calculated via an equation for 0-60 time estimation. The initial equation yielded an inadequate estimation for a stock SVX (of which we know the real 0-60 time). Therefore, I applied a 6% positive margin of error into the equation to correct subsequent calcuations.

I second that! So long as you make a chip for OBDII cars!!!

Just kidding...

...but don't forget us!

does this calculation take into acount gear ratios and if it does could you do it with 4.44? thanks.

By the way those numbers make me want to scream out like a little school girl with excitement.
