Recalibrating stock ECU possible? 1993

[highlander]

Hello guys.. I'm new here...

I was wondering if its possible to recalibrate the stock ecu for an ls400 93.

I need a new ECU since mine is toast for whatever reason and i need one asap btw...

Thanks

The car simply knocks too much here in hot weather.

There is a company sells a modified or recalibrated SC400/LS400 ECU . Very pricy.

Extremely pricey... for that pricing i would install a complete ls1 engine in there with everything and be done with it.... have more power, more gas mileage and still tune it MYSELF!
