nah calvin, it stillw asnt working before my seal blew on my crank, which i have yet to repair. i tried mbar at 225, 235, 240. if you look at my logs, my mbar would go to like 213 ish when i let off the gas..then it just ocasionally blips to 225...and fuel cut flickers, then it goes back to 215mbar ish.. and fuel cut goes back on. whats strange is that it seems like fuel cut was ignoring what i set the mbar value to..like if i set it to 235...fuel cut would still flick off when i hit 225mbar in my logs. Strange behaviour. its in my logs, increase zoom and have a look.

I posted my Log and Cal on page 4 It doesn't work at all now. When it was working I had the mbar set at 198 and TPS set at 5% and I no issues it worked great. I have tried increasing mbar up to 300mbar and still no change.

this is very strange... I'll test in a car myself later. i did already and it worked. you have 2 fuel cuts i described it somewhere.

yep, I read your post about the 2 Fuel Cuts TPS Based and MAP Based. But it is not happening. I am not seeing it in the logs or on the WBO2 Gauge. I tried doing a Force Update just incase I had the wrong version, but that didnt help either.

Very strange indeed... Yesterday I had a fuelcut problem car too but with a bit tuning and setting the mbar's to 250 made it work perfectly!

higher altitude I set mine @ 180,2% and 500ms. Works well for this setup.

I've increased the the mbar from 180 to 300 in 50mbar increments and no change.

does anyone else have a datalog where when u let off gas, mbar goes to say 195-215 ish...then suddenly blips to 225 ish..and causes fuel cut to disable. also what should \"Above (minimum) rpm\" be set to? like shouldnt this be like 1200rpm or something...because say your in fifth gear and you slow the car down alot, won't fuel cut stop working if rpm goes below this min rpm? and \"fuel cut restore\" can both of these be explain calvin? and how they work together? you should def have another look at this datalog im going to post. i cant post my log for some reason right now..saying connection timing out..its the log i posted a few times back called \"fuelcutsometimesworking.elf\"

Is it possible your running rom 64 because 64 dos'nt work . just exactly like what your saying.

Maddog20 · Post by **Maddog20** » Fri Jul 17, 2009 12:01 pm

it's rom 63 I have noticed the people that are Authorized Ectuners are not having any issues and the people who are not (Pro-Users Single car License) are having issues. Is it possible that Pro Version has a bug and the tuner version does not? Because I know it's not something I did...up to until these last few updates the Fuel Cut worked perfect.

I'm having the same issue. Started at 180 mbar, increased 25 at a time till hitting 300, and nothing. All I did was lean out the first column, and that did it. Fuel cut doesn't activate, but it decels ok.....................

min rpm, fuelcut will only start working above that rpm restore rpm, if a fuelcut is active the fuel will be restored below that rpm. e.g. only works above 2000 rpm once active it will restore fuel belove 1200 rpm
