Is it standard to remove the MAF sensor with the Flash N go tunes?

No,


The MAF sensor stays attached, as the ECU still uses it to monitor other parameters. Removing the MAF, even though it is not being used to meter air, would result in the car running poorly or not at all.

@sales@delicioustuning.com when running multiple maps, which number does it automatically default to during each start up?

Also, if the rear O2 is switched off in the tune, does it mean we could technically drive around with a rear sensor disconnected (at the harness) without throwing the CEL?

My plan is to get the exhaust shop to hook up the AEM wideband into the rear O2 location when installing the new header, then drive home to connect the analog output wire to the ECU myself....so during that short period the ECU would not be 'reading' anything from the rear sensor. Will it still throw a CEL?

Edit: nevermind I found out it defaults to map #1 at each start up, unless you turn key to "on" position twice before starting ignition. Also found out it's not good to drive with sensor installed but not powered, as it'll foul the sensor.

Ok thanks. I was reading about the racerom upgrade on your web page and it stated:

The Speed Density (SD) feature changes the way the engine load is calculated. When SD mode is activated, the ECU will disregard the MAF sensor reading and will instead calculate mass airflow based on Engine Speed, Manifold Pressure and Air Temperature, this allows the MAF sensor to be removed, and a larger intake may then be fitted if desired.

I guess that as that may be an option with the software but that is not the way your tune is setup.

Thanks!

Pat,

Correct, but notice the Air Temperature is used to calculate speed density. Well where does the Air Temperature come from? It comes from inside the MAF sensor so you still need the MAF sensor unless you decide to run an external temp sensor which can also be done. Something we are looking into with our FlexFuel system.

Still having the same warm start and idle issues....
No resolution yet.

Hmmmm, have you smoked tested your vehicle yet to make sure there are no vacuum leaks? Just verifying.

Also we are working on updating the tune further for improved idle with A/C On/Off conditions and balancing that has been fun.

Anyway I want to let people know also that creating these tunes and adjusting them is not as simple as, just send a quick update. There is a lot of development time to build something, literally from nothing and to work in all on all cars, with varying forced inductions kits, on varying fuels, in varying climates, with varying injectors, varying map sensors, with a speed density tune on a car designed around a MAF sensor. So please be patient, this is rocket science and are continuously updating the tune and testing every day, literally.

So I understand people want that perfect tune and that is what we are here to do, but it takes times to perfect it further.

Did I mention we are working on CLOSED LOOP FUEL CONTROL under WOT conditions. So now we can perfectly target AFR under varying loads, different boost levels and in different gears.

Please be patient, as we continue further development and add more features, while refining other ones.

Very true! Bill works long hours and weekends sometimes and does what he can to help if someone is having issues. It's basically come down to just dealing with the idle issue with the A/C on. He has made vast improvements, and running the turbo kit I have on mine and with the starting issues after my built Crawford block was done, it is near perfect. He showed me on his laptop what goes on with the fuel map with the A/C on. Seems like the ecu cannot make up its mind lol. Thank you again Bill for taking a look and fixing my idle issue and I'll send you some logs tomorrow!

The car barley idles when coming to a stop, it bogs and bucks trying to pull out from lights. it pretty much refuses to start warm. I was told my logs look fine initially.
I have tried multiple sets of vacuum line sizes and fitting styles. Nothing changes.
Its pretty much a highway only car at this point as I am sure I am killing my expensive clutch trying to drive it.

I remember when I was one of the first few Bill dyno tuned on the dyno of FRS / BRZ platform back in 2012/2013. I received an amazing tune then on my FI FRS, but I have to admit. Bills tune then were at the top compared to any other well know tuner with its custom mappings. Comparing my last map to the first one, I gotta say that theirs definetly rocket science into it because their no where near being close to each other. If it takes Bill an x amount of time to get back with a tune then I'll wait. I prefer taking a tune that has been perfected as much as it can by logs then a half fast job tune (done by other tuners). He's a very busy guy with thousands of customers and with product development and R&D, so people please be patient. Keep on rocking @DeliciousTuning!

As an FYI, we literally sent a new tune out last night to a JDL customer and his idle is rock solid.

So send me another log of idle, AC off and I will look at it again. There must be something going on that I am just overlooking.

I think 2 thing should be better even in NA tune:
1. targeting AFR be stable at wot
2. CL/OL transition delay goes to zero

hope to see it at new 2015 tunes

sweet. any idea why more manf dont do this from the get go?

Some manufacturers do in fact apply CLOSED LOOP under full throttle. Mercedes for example does and I would assume they do not because if the front O2 sensor fails slowly (which they can do) it usually causes them to lean out.

This is why we have ours in development and we are thinking about this as we develop the tune and have some solutions for this when the time comes, that the sensor will fail so it will not run lean.
