      this doesnt look right, suddenly there is no noise on the green signal, something has changed...  looks electrical to me.... BTW not sure I know what the AFR target actually is, I thought the AFR target was the map data cell value? Has it jumped to a part of the map that has areas where there are lots of high values in it?  I think with the software you can bring up the maps so you can see which cell its using...

      I see a target AFR of 17.9 on one of those. That doesn't sound at all right.....

      I've had a sleep on it and a quick look this morning suggests my VE map might have been out.  The software has the capability to auto generate this based on some engine inputs.  None of which can tell it that the engine is not 16v or crossflow, but hopefully it's close enough. I was confused yesterday because the auto tune didn't seem to be actually changing anything.  A quick tutorial this morning suggests that the default figures I was using on autotune are wrong, so I'm hopeful I've improved a few things and I'll get it running nicely tonight.   @mpbarrett  I'm suspicious of earthing isues too, but haven't modified all that much when installing the injection bits.  I've got the full tuner studio licence so can see everything.  Working out what are the useful bits is the challenge!  The AFR and target AFR graphs suggest that somethings off enough to prevent proper control. This section below after starting shows it controlling well for a bit (red line and green line are identical), so either theres an intermittent earthing fault (it's a triumph, there are probably several), or the settings are just close enough for it to control for a short while at idle.

      Excellent work! Getting it running is the difficult bit, now its just a bit of tweaking   Multiple electrical problems I wonder if you have an earthing issue? Whats the setup, can you monitor where its going on the map when  its running? mike

      You won’t get much joy from MAP with  ITBs. TPS (AlphaN) or hybrid/blend will be the choices.   The latter should ultimately give the best results but trickier to get right (IMO). What do you have in the way of a base map?

      Took it for a bit of a drive and it's not actually very happy.  Electrical gremlins (oil pressure light is turning on, rev counter not working), & going very lean at anything beyond about 5% throttle. The battery had gone flat so when I first fired it up so I had to jump it to get it to start, I'd hoped this was the main issue and that drivign it for a bit would charge it up and thing would improve, but that didn't happen.  I'll look at voltage correction for the injector opening times, and I might have made a mistake on the control alogrithm.  Speeduino gives the option of MAP, TPS and IMAP/EMAP.  I'd assumed that the latter is the hybrid MAP &TPS control liked by ITBs, but maybe I'm wrong. Plenty of suspects for the issue, and it should be a simple fix once I've found the culprit.  I'll mull on it tomorrow  and try again in the evening.

      If you have one of those endoscopes that have an inbuilt light it could work, with some patience. However, and I can't stress this enough, you need to leave a good while for any stray oil to descend first. Otherwise any drops of oil absolutely will drop directly onto the lens and blur it, just after you spent 5 minutes getting the damn thing in the correct spot to see something useful.................
