I have the Rogue version of M-tune as well as the Rogue DME. My car is running very rich at WOT(10:1) and I'd love to either get a DME Tuner or have Josh look at my logs and burn a new chip.
I have emailed him a couple of times and no response. I know he's a super busy guy with a young family and I totally get that, I was just hoping to get some tech support.

I believe he has passed the baton. Lindsey Racing is it...

Except Lindsey doesn't support the Rogue- Focus 9 DME...

I have the M tune as well... same rich issue at WOT, as well as a high idle problem.

currently half heartedly searching for a windows 7 laptop to use with the ostrich tuner, but support on that software platform ended a while ago. Seriously considering VEMS.

talked to Dave at LR awhile back about chips for the Mtune. The new stuff is not backwards compatible with the OG Rouge MAF. So...I would suspect the DME is also obsolete.

I am sending my Rogue DME to Focus 9 for repair as per Joshua's instructions a few weeks ago so he is around.

How did you contact Josh?

My experience is that in summer months the tune runs a bit rich, I think due to a combination of conservative variables. I believe AIT fuel compensation being the main one. The curve should be fine. If it were me I would add an adjustable fuel pressure regulator and tune with fuel pressure. Quick and easy.

DarrenD

That's a good idea. I did re-install my stock FPR and things got better(less rich). I'm hoping with an adjustable FPR it gets even better.

The adjustable is a must as the Bosch 3bar is actually around 3.1 or higher.

DarrenD

It runs far too rich on the recommended Bosch 3.0bar. I put the stock FPR back in and it's still too rich. I've been going crazy trying to find any boost leaks but nothing has appeared.
The car runs very well, just stinky rich at WOT. Idle and cruising AFR's are great. I'm getting a slight misfire at WOT as well in the higher RPM range. I closed the plug gap to .025 and installed a Blaster 2 coil and it's better, but still there. Could be the absurdly rich AFR's.

The advice of running an adjustable fuel pressure regulator to adjust a tune (any tune) is a bad advice.
A proper tune is configured to run at a specified fuel pressure. If you have to adjust the pressure to compensate, then there is something wrong with the car or with the tune. Either case must be fixed properly, adjusting FPR is a bandaid. You might as well switch to carbs and start changing jets.

A tune should not drastically change between summer and winter unless the fuel E content changes (especially with E85) . The IAT when handled properly in the software, should help the running conditions not hurt as mentioned.

Fix the real problem, playing with FP is covering up the problem.
