I've had DFCO problems that no one seems to be able to explain. A tuner I spoke with mentioned maybe trying to flash a different OS to see if that helps. I am assuming, though, that writing another...

My idle isn't high. I can't remember off the top of my head but it's definitely below 1000. I'm thinking 850ish? I upped the transient fuel when trying to sort through lean between-shift AFR. I know...

Also finally got around to updating versions and checking out your tune, Luke. I don't see anything in particular in the DFCO tables that would make me think I have something way off-base. Thanks for...

Correct, AFAIK, but I think I was slightly confused on when the Active Spark Threshold came into affect. Looking at it again -



I think I was misinterpreting this as the number had to fall...

I haven't moved to the newer version yet so I can't look at your tune, but I'll do that later.

Question for anyone - my DFCO Active Spark Threshold vs. RPM table has 0-4* worth of spark in the...

Also probably worth asking - is there anything else in the wiring, like Luke was thinking, that would affect this? My understanding is that the M6 cars don't know what gear they're in (mine always...

Great, thanks. At some point can you log the current gear as well and see what it reports?

Bumping this back up. Luke, have you made/seen any changes? When I log the current gear, it always shows "3", but I don't know that it affects anything.

Driving home today, I'd cruise at a slightly swinging ~14.7x (currently OLMAF), come to a stop light, idle would drift/peg lean, then when I started cruising after the light changed it'd hover around...

I have an NGK AFX with the NTK sensor. I'm not sure how old the sensor is, but I have free-air calibrated it several times. It was never significantly off, I just wanted to make sure of the...

No updates from me, the car is parked for the winter. Not sure if Luke did any other testing.

Awesome, thanks.

Sorry, should've quoted. I'm the OP. I was curious if Luke had functional DFCO in any gear.

Does yours work in any gear?

To update this -

I tried flashing the original, non-RTT/enhanced OS (just to attempt to rule out some sort of OS corruption) with no luck. I can't think of anything else that would cause my...

I was adjusting mine a bit trying to deal with lean tip-out. With Ford 36# injectors, I increased the value to .045 and was able to reel in the lean spikes. My idle IPW is ~2ms and my DFCO IPW is...

Not sure what you mean? From 06.832-14.151, I'm in 4th gear and off the throttle. That was down a slight grade, which is why speed is increasing a little bit, but TPS/speed/MAP/RPM thresholds have...

Any thoughts on what else might be causing this?

This is just a quick snip from the log, but it starts in 4th gear, then I toss it into 3rd, where it seems to go into DFCO. Wideband is ~12.5:1 in 4th, ~2.0ms IPW, then ~15.87:1 and 0.5ms in...

I grabbed a log I can post later, but TPS looks fine at 0.0% and .53v, which are the same values as when I can get it to enter DFCO in lower gears.

I upped transient fuel a bit to try to smooth out lean spikes in between shifts, which worked.

To be clear though, when DFCO engages, IPW goes to ~0.5 and my wideband pegs lean. In the example I...

M6 car. In gears 1-3, DFCO works fine. In 4-6, it doesn't seem to want to enable. The map readings are similar in decel in each gear (~19-21 kPa). The RPM/speed/TPS/MAP entry values are all met.

Found this thread for my shifting commanded AFR. I changed my rear O2s from "No error reported" to "No MIL Light" and I'll see what happens, but this seems like the fix for that. One thing at a time...

A question about low RAF and idle surging. When I got the car, the RAF was twice as high as it is now (and, realistically, probably closer to where it's supposed to be). What would be the downside to...

I was trying to track down the cause of the low base running airflow numbers, so I bought a regular oil cap to replace my breather filter oil cap. Cap on, fresh air line ran from the TB to the...
