Recently every automobile maker is very nervous about gas smog and fuel
consumption.
Especially California is famous where carried out a very strict smog test.
It is
even if Japan too.
To full these strict conditions, a program of stock ECU has to be lean type
than being powerful.
This means that maker's program is on a balance which you can not keep easy if
you want any modifications.
Adding on supercharger system, completely A/F crumbles to the touch,
it is too hard to control by a sub-ECU iModulatorj unit like dummy signals.
Engine control is not so simple.
To get the correct performance from tuned engines, ECU management is absolutely
to be applied
It would be no way for tuning makers using modulators to down sale prices,
but we want to emphasize that ECU like freedom is very reliable and possible to pull
through engine performance.
We can say the just same thing about camshafts.
Camshafts are one of important items. We always choose it after discussing with
clients.
Street or circuit, how about straight distance, how about top speed and rpm,
with carburetors or 4throttle injection system, or stock throttle etc
There are many things we've get to confirm for our clients.

And next is ECU finally.
If a customer requests to install camshafts without ECU review, never suggest
high-spec camshafts to him.
It is impossible.
Do not wrong us, please.
ECU review is very important even if it is stock engine.
But always keep a matter of client's budget in my mind.
I never say ECU in not necessary for not high-spec camshafts.
To save the cost, sometimes accept for high-camshafts without ECU modification.
As for ECU modification, ROM tuning of stocks is the most popular in Japan.
It is the same situation in Maruha, too.
But available for only early models,
and for light-tuned engines.
Maruha Rom tuned ECU for NA6CE (90-) 1.6L
Freedom ECU has very wide range for any modifications, any model of Miata.
Exchanging any spec camshafts, bore up, supercharger, air-flow meter less of
early model, carburetors,
4throttle system, big-throttle of stock body.
NA6CE (90-) 1.6L without Air-flow meter which is
very large resistance of intake air.
Control by Freedom ECU
Maruha has so many data like above conditions with Freedom ECU, and can
supply it in-put our original program to you.
