Daily driving ever since, 7 days a week.

Only one significant issue so far: Ripped left engine mount! And I didn't even really abuse it. Much.

Have a replacement that's stronger to install, so will get that done sometime in the next month or so, I suppose.

Only limitation is inability to floor it in 1st without cam cover and brake booster doing the load carrying!

80% throttle in 1st is okay, though.

Still no tune. Still no wideband. Currently just into full tank 2.

So it had:

20l of random 91 RON from a bottle
20l of random 91 RON from another bottle
40l of fresh 95 RON from a pump (to prevent pinging on no-tune)
50l of fresh 98 RON from a pump (because handier than 95 RON station, and similarly priced)

Trying to log distances for this 98 tank so here's so far:

gas station to city to collect mrs
city to home
home to work to home

more tomorrow :-)

Things are great up to 4450 RPM, then turn to custard:

I really should dig into that a bit more closely. But tonight I back ported some tune changes into source in preparation for removing the ECU for use in the hotel. Took the old girl for a spin, tested a few things, richened up the top end a lot, made no difference.

In another log pull it went to 5200 almost cleanly then stayed there, as if it was on a limiter, but yet not.

Logs continue at seemingly full speed. Seems like there is CPU power to do the job. Just relative timing issues to resolve.
