[FEDE/E92]

Last night I finally got my OFT stage 0 flash on my car. As soon as I satrted the car the servuce engine soon light came on and ran rough, Code was misfire cyl # 6. I went ahead and flashed back to stock and the code went away. My question is does the stage 0 flash changes over stock flash that much different that will make it misfire at idle, when flash back to stock run just fine, or I might looking somekind software programming issue or more mechanical. Car has new sparkplugs and hpfp. Thanks for any help

After you flashed it did start and stop the car 4 to 5 times. You get the check engine light but it goes away after the fourth or fifth start up

I don't think it should be running rough. I know the SES light comes on but it shouldn't be running rough

I had 0 issues, first flash and start up ran like a champ.

Call the people that you paid your hard earned money to, it OFT comes with support, so abuse it!

I have a OFT also and I've seen first flash take a few seconds to smooth out and the car will run really bad. Shut it off, clear codes and start up again. Should smooth out. If not, then you have an issue with your flash and you probably need to re-flash the car. Make sure you have a charger, low voltage is not good and can cause major issues.

I don't know if you noticed, but Wedge did an OFT custom flash for a guy in Illinois a few weeks back. RickyBobby said it's supper smooth and quick for a car with only a DCI. Tune took a half second off his qtr mile time from the stage 1 flash he was running. No throttle closer also. I think he figured out how to map the WGDC using the OFT.

I had a bad experience with Vishnu Procede and the customer service was completely unhelpful. I had very similar issues that you are having. I ended up sending it back and going with Cobb. No problems with Cobb.

I emailed them got a quick reply, Im trying to rule out easy things spark plugs, ingnition coil and injector.

Update: found a fouled plug on cylinder # 6 which is weird cause I swap my plugs the got about 5k on them. Car with factory tune pulls nice hard and no issues. As soon as I flash it with the OFT stage 0 the and get on it the car misfire hard and throws a code for misfire cyl #6 as soon as I go back to factory tune it runs perfect. what to do next?

Is it fouled because it is running rich? If just that cylinder is fouled, would a leaky injector cause it.

factory tune probably runs less timing so ignition is not expected to perform as much.

Not sure why it fouled but it didn't smell like fuel.

What mods are on the car? Reason I ask is you could try stage1
If not I would erase re downloads the oft files and try again
It should not be stumbling that bad first start up

Also Wedge is first class for helping along the OFT platform tunes
I have his stage 1 map in my car and is GOLD

Once you get this sorted out drop him a line

Car is completely stock right now. Already did that still the same

It may be a coil or injector issue by the sounds of it. To rule out the coil, just swap cyl 5 and cyl 6 cool and see if the misfire follows the coil. If so, replace it and you should be good to go. You can do the same with spark plugs to rule them out too. If the problem still persists then it may be a bad injector.

It is possible to disable the misfire diagnostic with the OFT map. But it's better to get to the bottom of it through a little trial and error. The reason your stock tune isn't running into misfire (yet) is because it is running lower boost and isn't putting as much load on the ignition system. But give it time and it will start to misfire as well.

Thanks for the reply I already ruled out the Coil and plug. Is there any way to test the injector?

Did some dataloging pretty kewl

Holy second coming of Christ. Shiv is that really you? I have not seen a post from you on here since the 128i OFT dropped. Why no replies on the OFT threads over the last few months? Any improvements or upgrades still being developed for the OFT?

For anyone interested I custom mounted my OFT and I am very pleased with the outcome. The bracket gets mounted behind the radio trim and attached with the stock bolt. It is a solid metal mount and extremely strong. The mount was purchased at Bimmian.com. You also need an OBDII extension to reach the distance. (amazon)This mounting location does not interfere with passenger leg room or comfort and is easily accessible from the driver position.

Something pretty weird going on in that log. AFR from bank 1 is pegged at 30, maybe a faulty oxygen sensor. AFR 2 is pretty damn lean throughout the log. You should check the oxy sensors.

Fuel trims are dead flat at 0, some major throttle closures as well.

^^ Good tip on the O2s ^^ I replaced mine at 56k miles. Use two Bosch 17098, much cheaper than one 17098 and one 17102.

Maintenance: severely crudded up valves or poor PCV system dumping oil into the back two intake ports, old plugs, weak coils, etc. Also a slightly leaking injector can cause long cranks and poor running on cold start. It may not happen on every start - mine does it a couple times a week due to 2 leaking injectors. If the injector leaks badly enough under very high pressure (due to increased boost/tune) it can cause rich misfires.

Otherwise I have seen another car with cyl 5 misfires with the Procede on Map 1, no misfires stock. Found an injector missing the decoupler element in cyl 5, causing the injector to move around. The problem was unmasked with the tune due to higher cylinder pressures. We installed a new injector with new seal and decoupler, and it never had a problem again. The bore in the head was slightly damaged which requires a new head, but the new seal was able to hold up for at least 2 years so far...

[FEDE/E92]

Thanks I'm leaning towards leaky injector. I been getting mix responses about swapping injectors just to test the injector to see if the misfire moves. What you guys think of doing it really quick to test the injector it self?

[FEDE/E92]

Anyone?

[JamesM3M5]

Pulling them out and swapping them around is OK, but count on replacing the injector seals if you are going to leave them in for good. Let's say you quickly swap #5 and #6 just for diagnostic purposes. Misfire is still on #6, so you don't replace any of the injectors. You'll have to pull them back out, replace the seals and decouplers, and reinstall. Replacing injectors seals requires a small set of tools from BMW to smoothly stretch the new seal over the tip then shrink it back down to size.

New injectors come with new seal rings but not new decouplers. Always replace the decouplers.

You must also have the proper coding cable to program the injector values into the DME. If you don't do this, it may cause other problems that will mess up your diagnostics.
