Time for some updates
I got the engine finally assembled and have taken a few test drives the last couple of days. No fires so far
I have struggled a bit with the tuning, as the engine characteristics have changed quite a lot, so my fuel MAP was way off. I was running in so-called ITB-mode which combines TPS and MAP signals as load in the VE table, and this was no longer very representative for the current engine.
I saw that I have a lot more noise on the MAP signal than before also, so decided to use so-called alpha-N mode which only uses TPS signal as load, and within a few minutes with the auto-tune, it ran decently.
Some fiddeling with the idle, as I had WAY too much fuel at idle, so once I started leaning it out, the rpms went up to about 2500. The cable based throttle system is super-easy to adjust
So now it runs "ok"; it needs a few more miles with auto-tune and then some smoothing of the maps, but so far I am very pleased.
pressure and temps also seems ok
I still have some problems to get it started though. Worse when hot, so I think I will replace the starter motor first, and see if that helps. It is probably 40-50 years old... I already replaced the battery.
I can soon plan a dyno session, and it will be interesting to see how that goes. It certainly feels a lot quicker than last year already.
