[T3] Bad day at the (FI) office

We’ve now got close to 50 miles on the new ECU and the issues of last week haven’t returned. How about this though? Since installing this ECU, we seem to be running even richer (by the AFR gauge) and the fully warm idle sounds to be around 1100-1200 rpm. It doesn’t seem to come down to what I previously had it set to. I can reset the idle to spec and see what happens, but I thought this was an interesting phenomenon. Plus, we still have to address the rich running. 15 mpg isn’t good by any measure I’m aware of but what to do about that? I should perhaps add that we have a 100Ω resistor inline with TS2 at the head fi that matters.

Also  yesterday I noticed the speedo needle has started slightly vibrating between 30 and 50 mph. Between 40 and 50 it ticks loudly as well. I haven’t had much chance to go above 50 so I don’t know what the needle does there. This vibrating and ticking wasn’t around when I drove last Monday or on Saturday. I noticed it yesterday and today. Sean kindly helped us install a new cable two Saturdays ago as we seem to be incapable of correct installation….this is now our 3rd or 4th cable in 4 years. 

If it matters, we had the speedo out last spring to lube the inside because it was howling and whining like mad. I don’t know if this kind of higher speed vibrating and ticking is cable related or speedo related.
