Smoke Show Tuning mod

I want to keep a bit more Smoke on the upper RPM band say above 2200 to about 3200 RPM s under acceleration. the smoke seems to taper off quite a bit probably due to the 6637 intake and cold air setup. I have only used it a couple of times and it seems to do well at low RPM but tapers off later. which parameters should I change. as it's under acceleration I don't think the Low boost fueling will affect it. wondering if I need to change the Fuel Limit vs RPM map to allow more high RPM fueling as it seems the Mass Fuel Desired will already allow 125% fuelling at high throttle positions
Maybe It would be better if I drop the ICP at high RPM to get less atomization thus more Smoke.

PS for Jack, We already know your thoughts on this Tune so you don't need to add them here

Besides I am doing this more as a learning experiment as I want to tweak my other tunes to get rid of the Smoke at high RPM as Its just wasted fuel. would love to be able to Floor it at 100HP and up settings and not have a smoke trail....

Short of actually losing boost, there isn't going to be enough fuel from the injectors to smoke as much as you want at higher RPM.

If you could raise your LBF to 100% across the board, put an intercooler pipe cut-out in, and stand to have zero power.......

So, there's no way to inject fuel after TDC to create smoke? Or will commanding injectors open that long send overlapping signals? Just trying to butt in here and learn a little. Forgive me if I'm way off base.

Welcome, the best way to learn is to ask lots of questions... we are a small group here in the Minotaur forum but friendly and helpful folks

Unfortunately I have been busy with other projects this summer plus was sidelined for several weeks with cellulits in my knee along with a skull fracture and allergic reaction the the antibiotics, so I have not got to play much on this topic since I posted... you can retard the SOI but as Cody has mentioned else where on this forum, there is no single setting for SOI as it is constantly being changed by other influencing maps, parameters, sensor data etc....

So to answer your question there is plenty of ways to make smoke and most of the tunes do pretty good at it. I now have the telltale black soot stain on rear quarter panel of my truck... I actually want to try getting rid of some of the smoke on my 100hp setting as I have got pretty addicted to that one as my daily driver..... prob have to wait till winter when its too cold to work on my outdoor projects

I wish it was easier to look at other tuner's tunes.

My "smoke" tune by DI is my favorite to drive in. It's much more smooth and quiet than the rest of them. I imagine it has something to do with a slightly delayed SOI. It's obvious that the power is not as snappy with that tune, but it seems to pull longer and harder in the top end.

That's cuz smoke is good for torque but bad for EGT's.
