Raising the rev limit on stock ECU

[fax0815]

Hi,

I´ve got 2 build 4AGE engines, one in an AE86 the other one in an AE82, with 272° 8,5mm cams running on stock ECU, with the ignition slightly advanced, AE86 cat model (bigger injectors) and higher fuel pressure.

1st engine has been dynoed at 139hp (stock intake and exhaust) the 2nd one will be dynoed next week.

Since the engine is now pulling right to the end of the rev range (~200-300rpm before the limiter), it whould be necessary to raise the revlimit since there is to little time between the end of the powerband and the rev limit, making it awkward to shift quick and stay in the power band. Probably 8000rpm whould be good, as the engine can take it.

I´ve taked to the oldshool 90´s rallye boys, and they were doing some magic back in the days in darkrooms, playing with the crystals on the ECU to "reprogram" the ECU.

Now my question, ist there anyone out there who can still do this?

Are there any other options? Due to regulation of the rallye series and budget stand alone is not possible.

Any piggyback solution avaliable?
