Besides the soflt-limiter wire you can snip on the TLR ECU, supposedly there's some place you can send your Denso ECU and they chip out the epoxy potting and replace the chip to raise the redline. Only darn it I lost the info. Anybody know what I'm talking about? If one of us got that done we should darn well dupe the prom. I'd love to add a real 800 RPM while keeping the soft limiter, that would give me reason to consider lighter rods etc.
