Hey guys I finished my turbo install and it is tuned pretty decent runs at good fuel trims. But it has a problem, when I let it slow down to idle it has a problem sometimes, it seems to get caught in a loop of searching for the correct fuel to add, it goes rich and drops rpms then lean and kicks rpms up and keeps going until it gives up and stalls out. I think I read a while back Brian you drilled a hole in the throttle body butterfly valve? Is this what it was for? I am running the xede but next month am going to get a dp tune and use the xede for fine tuning and water injection control.

Thanks
Jason

Jason,

Shoot me a PM on miata.net to MXGeorge with your # and I will help you get it tuned and running as happily as mine.

I have this same issue and have not been able to resolve it for months.

What I dont get is it doesnt happen all of the time. Sometimes its absolutely perfect. Sometimes it will barely stay running when coming to a stop sign.
