are any of you with fuel cut problems using extended idle load resolution? have you tried the \"race\" setup from the basemap creator?

race just disables all all the sensor and check nothing special.. and enables debug mode in the ecu that is why maybe something works different? i never use that on any cars i do

Its that big of a deal to me, but it still doesnt work as well as crome/stock.

after creating a new map and doing exactly what chris has said, i have not ran into any problems with fuel cut. I havent seen afr's below 14 in normal driving situations when i push in the clutch. what load number (in mbar) is your first column? What basemap are you using?

Its a P75 map. My load is 200mbar, 0% tps. I had it at 208mbar but it was bucking at low throttle. I havent really tried tuning the tipout coloumn yet because Im lazy.

My first column is untouched ATM, 128mbar.

set fcut to 235 and tps 5% or 3%

what are you calling BS? you think i'm just messing with you? if so many costumers says that thay have this issue why cant you just fix it? i'v tuned systems much more complicated then ECTUNE, if thats what you are implying. mabey its because tuner version has a fuel cut map? you didnt answerd to what i asked before, can you make this feature or not? if not i cant see a reason keep working with ectune.

i rewrote the whole routine!!! decel fuelcut really listen to tps, mbar, min rpm, restore rpm. now also disable fuelcut work. e.g. if tps < 3% check mbar if tps > 3% decel fuelcut not possible why does honda make such a mess of the stock code bleh! if they did it right in the first place:) Anyway i just test it and it's working perfect.. I noticed during testing.. if mbar was higher then mbar cut and tps higher then tps % you had a weird cut above the min fuelcut rpm and it reset it self to the fuelcut delay amount. is that what you guys have been talking about? Can racepack, ckretvix drop me a mail so i can get out a test version. well anybody that notice this problem drop me a mail at calvin @ ectune com

btw with the current version try setting the tps much higher like 10 or 20 and problem is gone too don't ask why ask honda engineers

The problem I'm seeing is a cyclic leaning action, but too lean to burn properly and smooth. Fuel isn't cut, but not fully engaged - somewhere in between. Strange thing was the injector DC was showing more than what would have been necessary to achieve +19:1 afr. Calvin, I really appreciate you looking into this; I'll drop you a mail.
