Phoenix Switch-On-The-Fly Chip (DISCOUNTINUED) (Disabled) Power Hungry no longer sells the Phoenix/TS chip, but if you need custom tuning we can recommend a few really good tuners that will be able to still provide tuning and support for your chip. If you have any other questions or comments about the Phoenix/TS chip, please post it here. |

Has anyone done any tunes for this type of fuel to limit smoke at idle? I still would love to get this done. I tried to set up a live tune but it didn't work out

What do you think Cody, something with slightly advanced SOI and maybe ICP in the idle and low RPM ranges?
Just out of curiosity what ratio of atf are you running? |

The thing about ATF is that it's going to add a bit of viscosity (thickness) to the diesel fuel. Probably not measurable, but temperature may have an affect on it. Secondly, the ATF is going to combust slower (slower flame speed) and likely add a bit of lag to the actual ignition point.
As far as the ratio goes (ATF to fuel), that will have everything to do with the efficiency of the engine. You're certainly not going to hurt anything by running factory or aftermarket tuning designed for fuel-only use. However, I agree that a smidgen of SOI increase may help. However......if you're running ATF tunes without ATF, you may run into some combustion noise and possible engine damage. But, like I said, a SMIDGEN of advance....probably not enough to matter actually.

I ran about 70% used motor oil in my '94 PS it smoked a lot at idle but ran good other wise, had more power, boost and EGT, but fowled a few injectors after 4-5K miles. The injector(s) were dumping fuel.
I ran this truck on waist veggi oil for a 150k mile before this and only had to replace one injector.

We've done VO, WO, and TFO tuning, all with great success. The key is atomization and careful attention to SOI (timing) curves as these make all the difference in performance and efficiency.
There are a number of systems out there that piggy-back the stock fuel system and activate when the engine reaches a specific temperature. These are preferable as they help eliminate cold start issue that may occur when using alternate fuels. I don't have any specific information on these, but a few members run this type of setup and have been extremely happy with it. I hope this helps.

Bill, If I send you my 6 pos , could you come up with a few "atf" tunes for me? Unless you are coming to the west coast sometime soon. I would still love to host a live tune at the shop.
