Exhaust soot w/ JDM Whipple tune

[KYmxracer52]

More power is always good. Understood about the sootiness. If you can adjust your tips out a little it may help with that.

Maybe it’s just telling me I should wash it more frequently.

Sure thing!

Ahhhh the joys of the “best guess email tuning”!

“We have that tune on 100’s of trucks”
And they are all close.

get YOUR truck dyno tuned. Then there will be no questions

That would be best. I just got it data logged last night. Weather hasn’t been best around here. As long as they try to make it better, I’ll be ok with that. But yes, I may have to find a local shop with a dyno. I believe there is one about an hour away that is a big Mustang tuner.

Don't listen to that guy, he doesn't know what he's talking about.
As long as you don't have mechanical issues, JDM will get it sorted out for you.

There may no mechanical issues. Everything has been great with it since install. We’ll wait and see what the data log looks like to them.

No.


Your just regurgitating some crap that became popular in the 2000's, it no longer applies. A tune by a knowledgable remote tuner like JDM is going to be better 99.9% of the time than your local dyno guy who doesn't have the first clue about Ford Copperhead tuning. They will not get the drivability right, the will very likely make a "good enough guess", then rely on the ECM for knock retard and fueling adjustment.

Then they are going to get a repeat customer, because your going to be back, over and over because they can't figure out how to make it drive well.

Tuning on a Copperhead or TC-277 (gen 2) is not simple, you need a lot of experience with the systems to be able to get them to do what you want. Unless your local dyno guy is a Ford specialist, that has spent a lot of time and money on classes, and gotten a lot of time behind the screen tuning one of these he is not going to be able to do the job an experienced specialist can remotely.

There are hundreds of items you could log, and you need to do it in the correct configuration. Thousands of unique adjustments for the engine, many of which have entire tables that need to be adjusted properly and hundreds more for the trans. This isn't a carb, or a stand alone, its a complex OEM PCM. You would have to pay a dyno guy a weeks wages to even come close.

Here are some screen shots of the tables and switches that have to be adjusted to supercharge a copperhead raptor, TC-277 is even more complex:



There is another page after that, but I hit my pic limit and I think you get the point.

Got a reply from Jim today and he said everything looked good to him. If I’m reading the log correctly, here’s my numbers.

-Lambse bank 1- .79-1.02 (min/max)
-Lambse bank 2- .79-200.41
-AFR bank 1- .72-1.06
-AFR bank 2- .69-1.07

Livelink wouldn’t record boost for some reason although I had the PiD selected. Not sure how to get it to log. From my gauge, it looked like it hit 11-12psi. Was definitely above 10.

What do guys think? This was from a rolling WOT run almost to the top of 3rd. I was running up on traffic pretty quickly, so I had to shut it down. Still hit about 90mph.

I would be happy with those numbers, and expect a bit of sootiness.
