Looking a lot better! And I see that the mbar settings is even above 330mbar! Glad to see things are solved. @Calvin, is this adjustment in the software going to be in the next version?

In my case I have found good results, lowering the fuelcut delay,and up mbr.has also dropped the rpm.i think but would be good to have the option of working only with tps because users mount aggressive cams or itbs may have better performance fuelcut

Because it is coming out of fuel cut and firing the injectors

Why? its fuelcut on or off. If you should do this on an easy way, you should have a lean condition for a certain period which is bad for your engine. Its either on or off. Nothing in between...

a lean burn is bad. air cycling through it no fuel = no issues.... lean is just high o2 content.

Hi, I noticed a small voltage pulse in my tps.could be that this is why the pulse duty.maybe that the fuel cut routine works only when the minimum reading tps,and not in the voltage range of tps.

I had the same problems with fuel cut switching on and off during decel. I did a pull and found min mbar values around 100 (min 90), TPS 0, fuel cut on/off. Fuel cut settings were TPS 5%, mbar 149. Then I played with these settings and did some runs in 3rd gear. When setting the TPS 0% and mbar 100, there was no fuel cut at all. Now I have set the TPS at 1% and mbar at 200 and I have steady fuel cut during decel. Problem solved :D

After. The first fuel cut spike is due to the rev limiter (which I have at 7000 rpm)

I've noticed that since last update my fuel cut is performing perfectly.
