fuel cut tips

Before I updated my .cal file to run on the current update, fuelcut was working fine. You can see the motor going lean once you let off the throttle. When I then uploaded my new .cal file, it doesn't work. The AFR's stay rich when off the throttle. I did not disable fuelcut. any ideas?

check again with the latest version. There was a bug that was removed in the latest stable release. I can post datalogs were it works.

Alrite, I just made a new .cal and still the fuel cut has no effect. Should I force update again?

I am having the SAME issues. This is on a totally STOCK B16. Stock map, injectors, the whole nine yards. The fuel cut light never come on. However, it does get extremely lean during fuel cut conditions but I dont think that the injectors are completely off as fuel cut with crome would yield an \"AIR\" reading from my PLX M-300 and now with eCtune it just says \"Lean\". I just force updated hoping that it something changed but we will see. I also have logs of this.

Yeah I just force updated last nite aswell but haven't had the time to drive the car yet. Let me know DSMR if you get around to driving your car. Has it worked before the latest update? Mine was working fine before I updated.

Just use a stock ol P30 cal with this. PLX M300 wideband but it is not necesarry as it will show no fuel cut registering.. The ECU doesnt not have the 5V mod for the wideband so you can not see the full range through the ECU..

Guys.. I tested it onces again. Attached you will find cal and log file(with comments) Fuelcut Details: Rev limit fuelcut: Kills injectors does not set inj duration to 0 TPS fuelcut: kills injectors does not set inj duration to 0 Mbar fuelcut: kills injectors and set injector duration to 0, fuelcut becomes active after the fuelcut delay(default 600 mSec) -If tps is above min tps for mbar fuelcut, Fuel will be cut if mbar drops below load fuelcut. -If tps drops below tps for fuelcut, fuel will be cut. Both condition the min rpm for fuelcut has to valid(e.g. above 2000 rpm) Fuel will be restored if rpm is below restore rpm I tested this with the current release. The rar file for demon and Pro users. i didn't test it with force update version. Everything will be updated tonight. Please see screen shots, cal, log file with comments. I verified with a stock p72 and p30 bin. Injectors cut off but injector duration is not 0, but injectors are disable. You can see this every nice on the engine sim or with a scope!! Thanks darren I can patch it that it's this way. but i rather leave it stock. Honda knows why they did this.

This log file clearly shows no fuelcut. I'll upload a new version on force update tonight so you can test again. Sorry. Maybe i mixed version up. The best try this one. http://websrv.ectune.com/eCtune.update. ... 5.2009.zip

After DL this, whenever I click on Settings I have a message pop-up \"USERDT=False\" Never seen this before on other versions. After clicking on OK a few times it goes away. Is this ok? or should i wait for Force Update version tonight?

Alright after the re-force update fuel cut is back again. I knew it wasn't my settings cause I triple checked them to make sure fuel cut was enabled. Thanks calvin!

it's a debug flag that will be removed the next update.
