Default Stinger fuel system development - 04-05-2019, 10:39 AM

We've teamed up with Fuel-IT to evaluate and develop a lineup of fuel system upgrades for the Stinger. And of course, the first order of business is properly evaluating the fuel system and it's limitations.

To that end we've added some new hardware to our development car. We've added a Fuel-IT flex fuel sensor so we can accurately monitor ethanol mixtures and use that data to improve how the JB4 does it's E85 tuning.

We've added a low fuel pressure sensor so we can evaluate the performance of not only the factory in tank fuel pump but the fuel lines, filter, and related siphon pumps, to track down the restrictions.

Finally, we've replaced the WMI kit with a Fuel-IT CPI (chargepipe injection) system which allows the JB4 to inject more fuel/E85 in to the chargepipe similar to WMI but right from the low pressure fuel system. This lets us get around the high fuel pump supply limitations and support more boost on higher E85 mixtures.

Some teaser photos, and a couple interesting logs. The logs are 50% E85, running map0, and map7. What's interesting is we've added fuel pressure low to the logging at the front of the engine to evaluate the low pressure fuel system. We are not seeing the expected low fuel pressure drop we would expect to see if any part of the low pressure system was a restriction. More work to do. But it was a surprising result to say the least.

Might be willing to assist development/testing on the VN, should you need volunteers.

Have been looking at implementing a Fuel-It ECA solution for a few weeks now.

Good progress being made here. Will post up some more data next week.

We're working on the CPI kits right now. Should be up for sale soon too!

sir,

I am curious to what kind of increase in power and torque you will get from this set up. Also, can you piggy back WMI with the flex fuel set up? And what would this yield? Final, question is to what point do you think the JB4 limits will max out and require an ECU tune to get the most?

WMI works with the flexfuel kit. By having both, and perhaps in a later version of firmware, the JB4 can adapt to the signal received from the flexfuel sensor.

I can't recall the thread, but Terry mentioned that power for the CPI and WMI are nearly identical. It's about preference, where with WMI you're running lines for the tank to the trunk and potentially sacrificing a spare tire in the process and CPI is handled all under the hood with the T into the low pressure fuel line, with either the chargepipe or intercooler tapped.

I don't recall seeing the final question answered definitively, but Terry has said that the JB4 can also work with an ECU tune to provide greater performance.

EDIT:

I found the thread, have a look Stinger fuel system development | Kia Stinger Forum
