Please help with no idle issue
MS-1 Extra 029y4a
MIata 1.8 BP N/A stand alone
oem CAS and Ignitors
Locost 7 build
TechEdge 2y2
Engine starts right up and runs a few seconds then stalls. I can not get the engine to idle. I have spent 2 weeks researching this issue on line and have tried adjusting required fuel to lean and rich but doesn't make any difference. I don't know what to try or look at next and would appreciate a look at my msq if I have a setting incorrect. Also any suggestion on how to troubleshoot my problem.
I have no running history on the engine.
Just completed the WBO2 build and not sure it's working correctly.
Thanks -Ron

Thanks SA58Junkie for your time to respond. I did leave out important info as I am using a Ford 2 wire PWM IAC. Based on MS1Extra Software Manual the upper temp duty cycle can be set to 0 to start tuning. I think this closes the valve once upper temp is reached. I know the valve is open as I can put my finger on the intake and lots of air is pulled in a start up. If I manually restrict the intake of the IAC valve I get no difference in results. The engine still stalls after a few seconds so I haven't dealt with adjusting the parameters of this valve yet.
I have changed the req'd fuel value in steps from 13 to 2 and from 13 up 25 but don't see any effect on behavior, after a few seconds it stalls. It always starts up immediately but still stalls.
Is there a file different than the .msq that you are asking for? I thought the .msq file was the tune file????
I think I have a bad setting that is giving me this behavior since I have played with the fuel for last 3 weeks and same behavior. I'm wondering if my RPM looks right as it seems be jumpy on the .csv- The engine oscillates a little before it stalls but doesn't seem to like the chart. I am using the stock CAS with shielded cable grounded at the ECU end.
