Ruf chips any good?

[Babalouie]

Hi Steve

I know that Steve Wong does a great job and has a (deservedly) good reputation in our community, but it's just plain fun to say "Ruf DME" It would be even more fun to say "Kremer DME" but I don't believe that exists

They any good though? I recall that the first versions of the Ruf chips had a 7200rpm redline, and that was later revised to a more longevity-friendly 6900rpm.

Have you ever had a Ruf chipped car on your dyno?

Cheers

Hi Kev,

We have not had a Ruf chip here to test against Steve Wong's or ours so I cannot say.

Its prudent to mention that any custom software is usually programmed for the fuel octane availability and Europe's 98 RON is quite different from our 93-94 R+M/2 gasolines. I would not run such a thing unless I checked the AFR's & timing very closely with some dyno testing at all throttle openings to ensure there is no chance of engine damage.

Fair comment, thanks

I'm in Australia though, so 98RON is what we got, too. But I agree, a dyno run with the new chip in place would be a good idea, just to verify. That said, it would probably be a good idea to dyno check if I went down the Steve Wong path, too.

Steve's chips are mainly tuned with CA 91 so I know it will be safe for 98 RON fuels, .

Ah, good point

I just had an idea...I have a spare DME, and do you think I can just install the aftermarket chip in the spare one, and just swap them over between dyno runs? Or does a DME need to "learn" with a period of regular driving before it can be dynoed?

No worries,...you can swap them without a problem.
