[T3] Temp sensor and MPS problems on new motor

[Jessica Chase]

Don’t worry - we don’t usually run it up to 40 in 2nd, but for the purposes of this test (checking AFR numbers under hard acceleration), we pushed it.  With this new fully balanced motor with a lightened flywheel, it was pretty easy to accelerate and keep on going. The motor didn’t flinch.  The owner’s manual says that we can safely go up to 43mph in 2nd so maybe we were just short of redlining it :) We’ve run performance Type 1 motors up to 5k rpm and the Type 3 at 40 in 2nd sounded not even close. 

We have a gas mileage log in the glove box that goes back 4 years. Mileage and fill ups are usually really regular (we drive the same route every week) and last week gave an anomalous 14mpg from 4 days of driving which is why I mentioned it. Surely, that’s not good. But it’s hard to keep experimenting right now with the starter issue. We’re only comfortable driving it together so we can push start if necessary. Otherwise, it’s just one of us needing the car to start 2-3 times a day without incident. 
Relying on the kindness of strangers in The Bronx, Brooklyn, and Manhattan, isn’t always smart so solo driving isn’t in the cards right now. As stupid and gratuitously expensive a new starter might be, we’re thinking of taking the plunge. Remember, we don’t have a garage to let the car sit in when there’s an issue. We have NYC streets and M/Th and T/Fri parking regulations to think about. 

We didn’t ground wire 18 when doing our “unplug” tests yesterday. Where would be a good place to ground it to? What even is the true function of that wire?

Driving-wise, the only complaint we have is leaning out not under WOT but on the way up to WOT. With the AFR gauge installed we might see cruise #’s of 13-14 but acceleration #’s of 15-17 and then 12-14 when we assume the full load switch kicks in. But yesterday without the load switch connected we were richer under acceleration than with it connected! It’s all kind of dizzying and without a bunch of factory graphs and values to look at, it’s all rather vague!
