Guys, I have difficulty tuning my car with the EMS to keep rolling the car in first gear steady without choking. The car idles smooth at 950rpm @ 14 AFR. My HI IDLE is set to +300 rpm. If i let off the throttle at very low speed (3 mph) the car keeps rolling for few meters and then starts to choke and goes very lean.

Any advice would be really appreciated, thx!

 

Sounds like you have something wrong in the idle-options. check these settings

 

I would say you could have a problem with your decel fuel. I would try to adjust the load and engine RPM that decel fuel comes on and see if that helps the situation.

 

Brian, many thx for this advice. Now it's making sence...i'll try it tonite and report back. What particular table/graph should i play with? Or should I just reduce the load to let's say -15psi in Decel Fuel options?

 

if you post up your map, ill look it over & see what needs to be done

 

here is my cal file

...i've played with the settings a little and saw some improvement. still bad with the a/c compressor on though...

any advice is highly appreciated! thx
