Rev limiter/shift light

[Englishmaninwales]

1400ss to 1800ss upgrade but retaining original distributor/cams/ECU/flywheel trigger pattern. I wish to lower the rev limit/shift light to suit the 1800. I understand the 'non reprogrammable' nature of the Rover ECU , but is there anybody out there who is clever and has successfully hacked one of these, or does this sort of activity leave one with a dead ECU?

 

Will eventually go down the path of a reprogrammable ECU/other engine upgrades in about 2 years, so until then if the Rover ECU is 'tamperproof', is my short term solution only to buy an after market limiter/shift combination,e.g. Omex speed system, or separate limiters and shift lights from Armtech or Aces? If so, any recommendations?

 

Thanks

Can't help with the Rover Mems question, my R160 has a MBE ECU. I have found that the shift light in the dash is next to useless, so I have just fitted a Aces shift light system.

Malcolm,

I don't think you'll find anyone to hack into the MEMS.

Why do you wish to change the rev limit??

I had a look at the "Omex Shift Light Sequential" at the autosport show - it looks quite good and cheaper than the "aces sureshift" benchmark.

I like the idea of the sequential lamp rather than a single lamp.

Being tight, I'm experimenting with a home made setup at the moment!

The 1400 rev limit is preset to 7600, shift light a nanosecond before (? 7400). Oily advised me to set the 1800 rev limit to around 7000.

Trust you to make your own!!
