Chaps I'm havin the same issue with poor startibg and no idle whatsoever
I've attached a image of my holding a high idle with a bit of gas can anyone
Tell me if any of the figures look wrong and may point to a fault.
I reckon air flow meter which is a Q45
Any help appreciated
Sorry about the size don't know how to reduce....

Hi Raymond
You can use ALT-PRINTSCN to get a screenshot and then use MS Paint and Edit > Paste it then resize, save and attached for forum posting
So far I see your MAF voltage about 2 volts which might be a little high. Can you post your BIN file currently used and capture a log file from idle, crank to running?

Ok matt ill try and sort that, only issue is sometimes when I'm cranking over the nistune disconnected and I can reconnect if either it doesn't start or does start.

timing seems low for a cold engine (52). possible cause is using knock values or idle switch not active.
set all timing maps to 15 across (0-3000rpm and up to load of 35).
might help it run until you sort out the real issue.
TP is up a bit high for 1500rpms. but the O2 sensor has a lean reference voltage??
constant "K" maybe too low if you have changed MAF/injectors.
TP scaling could be off a little too but by seeing the corner of the Map it seems relative.
maybe fill us in with a log file bin/address/ecu model that u r using would tell a better story.
