Anyway, sorry back on track. So I went out and VEAL was going great with GAIR not doing much, I stopped, got my grub and saved my map. IAT temps were just under 50C at this point so I thought I'd just log the drive back and see how it went. All was going well part way home, then I noticed my AFR's were jumping about and my RPM was rising even with my foot off the throttle and TS telling me my TP was at 1-2%! Now I've had this before and thought maybe it was just the throttle getting stuck, but my idle is about 900rpm (ish) and stopped at lights it was rising to almost 2000rpm! So I started logging from here to see if I could see what was going on. I also noticed that when off throttle in my overrun area, which is very lean, it was staying around 14.5AFR which is way off and completely different to what it was doing 20 mins ago on the drive out!
So yeah, AFR's are higher than they should be and RPM is raised, and it was always when either with the clutch down or off the throttle completely and it wasn't like it on the initial drive out or when the temps seemed lower(around the low 40's to 45C mark). If I blipped the throttle the RPM's would drop back to where it should be.
I've attached a copy of my log file for the drive back and my tune. The tune is still a bit all over the place at the mo but hopefully it may shed some light.
Any help greatly appreciated. Car is a '90 MX5 1600 running ITB's and 265cc injectors with no ICV.
Cheers
Rob

P.S. I zipped the log up as it said it was too big.
