I've been seeing ads on eBay about a chip that you can add to your miata
to gave you up to 20HP. It looks like all it is is a resistor (3.2Kohm)
that is plugged into your ECU connector. Has anyone else heard about
this? Does it really work?

try a google on rec.autos.makers.mazda.miata (this group ) the question
is asked before here some time ago.

Up to? It might give you up to 20 half pennies worth of electrical
parts. It won't do anything for your car, though.

So?

I would not do that. If you damage a wire, you are in trouble.

Yes.

Obviously. Otherwise you would not be here.

Want to buy a condenser from me? It will give you up to
300 hp for only $50.

I should also have a piece of wire somewhere.

You do realize that 0HP is included in the phrase "up to 20HP"?

And so is -10HP.

Yes.

Of course not.

If there were a trivial way to get an additional 20HP out of a
Miata engine, the engineers at the factory would have already
done it.

We engineers aren't idiots, you know.

If you want an additional 20HP, a super charger is about the
simples and cheapest way you're going to get it.

Supercharger cheap?? I think not list price for a Jackson racing
supercharger is 2800$ for a 1.6 and 3100$ for a 1.8 But they are whole bunch
of fun :)

No, I wrote "cheapest". Can you point to a cheaper way to get
an extra 20HP out of a Miata?

I don't disagree with your basic reasoning, Grant, but headers, catback,
milling the head, and a carefully-tuned Link ECU might yield 20 rwhp for
slightly less money than a JRSC. A technical nitpick, that's all.

Now, 30 rwhp requires either forced induction or a whole lot of engine
work (even more expensive, and less streetable). The standard JRSC or
GReddy turbo kit is worth about 35-40 rwhp. At about 45 rwhp, the OEM
clutch starts begging to be upgraded.

You can build a pretty fast Miata for $6000 in parts (plus the Miata, of
course). IMHO, anything less isn't worth fooling with. BTDT. If you only
have $2k to spend, it should go into the suspension and tires. Or sell
the Miata and buy a Mustang.

You're proably right. For the price of a turbo, you mabye
could get 20HP while staying normally aspirated -- especially
if you did some of the work yourself.

A good used 3rd-gen RX-7 would be more fun. :)

Using Avgas exclusivly as fuel can let you get quite a few more horses
happening cheaply. Up the compression, then advance timing. With 130 Octane,
pinging is waaaay less of a problem.

Of course for most of us the hassle & expense of obtaining Avgas outweighs
any economic advantage.

Correct. If you want to up the performance a little and add a couple of
horsepower here's the way to do it:

Careful with that Avgas. First, it is near impossible to find 130
octane. I haven't seen it in years and I've only seen it once in 30
years. The current avgas is 100LL The LL stands for low lead, and it
is not. It has so much lead that your cat will fry in only a few
miles.

A friend of mine used 100LL in his Ferrari and ending up having to do a
re-build.

I just drive about 35 minutes to my local racetrack
(Infineon) and there's plenty of 100 octane unleaded
street fuel there. However, even with a 7+ psi of
boost on my otherwise stock '02 SE, I don't need more
than about 95 octane to avoid ping outright...

YES.

It works!

But don't buy that one, I have one that looks just like a 4.7K ohm resistor,
and adds 30HP. Mine works wirelessly, you just neet to pop in in your
glovebox, and way you go. No messy & comples electronic modifications.
Just send $49.95 to my anonymous postbox, and it's yours!
