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.

Well, on Friday night around 1230am (technically Saturday morning) I ripped the hotel firmware off using the "karma" laptop and loaded up the last rip from April, and drove the car for the first time in nearly 3 months!

It was nearly out of fuel when I parked it up, and between that, being broke, and having only one ECU to share between the Hotel and this, I just abandoned it. But not anymore.

I took it and filled it with 98 RON 10% ethanol fuel (hmmmmm) and it's been getting some solid usage over the weekend until just a few minutes ago when I parked it back up.

First start was easily as if it had run yesterday. First key on I heard the dry pump gurgling and pulling fuel back into the lines, then stable/quiet like normal. Lifters didn't clatter like they did in the donor car and like they did after storage. One of them still has a bit of stickiness and clatters sometimes and goes away. I guess the amonia filled nulon lifter cleaner has mostly been doing its job. Good :-)

I'll have to put one of my other ECUs together for this car, or the hotel, so I can keep them both alive/available with ease. Both have the infamous motherboard molex connectors in them, so I guess it'll be my 0.7 Jaguar that goes in. Both also have water ingress issues, but neither are a big deal now with drainage in place and summer on the way. ... 2159396866


Pic from Friday night at the gas station before taking the long way home via the motorway :-D ... 1325240320 & ... 4053487616



Also, someone damaged it while it was parked for 3 months: ... 9647717377

ECU-less as of Sunday night, time for the hotel to get some love. Need to put a second ECU together so I don't have to play swaps all the time.
