I spoke with a Kenne Bell several times. They seemed to think it was a tune issue and not the bypass valve. They were happy to talk about it but never offered a solution.

I think I probably...

That's exactly what I'm talking about. And, that seems to be the issue.

I would love to be able to use that boost but I don't think the factory ecm is capable. I sure hope I'm wrong. Anybody have...

The original Kenne Bell tune and the beginning of the modified tune is included in this thread. I have made some more changes to the WOT AFRs that are a little different. I appreciate you looking...

Sounds like the same issue I'm having with a supercharged 5.7. I've heard it referred to as light switch effect.

I sure did. I have read that thread a few times. With my car being a 2010, the tables are quite different than yours.

If I'm reading correctly, you turned off NN while tuning? Did you turn it...

The tune that I received with the supercharger lowered the voltage some. Then, I lowered it some more which actually seemed to help with the light throttle/boost situation at cruising speeds.

But,...

Look into your throttle pedal voltage.

Do you think volumetric efficiency tuning would adjust the fuel enough for 2-3 pounds boost while in closed loop?

Hello and good day.

I own a 2010 5.7 manual transmission car with a kenne bell 2.8 liter supercharger. Is it possible to tune this engine with full pedal operation to run with the supercharger?...

I've been reading through this post and although some of it is way over my head, I try to understand it. It looks as if you are working on what I'd like to accomplish with my 2010 supercharged...

Is there a way to tune it in closed loop to operate properly with boost? I'd really like to get this car to run as smooth as it did without the supercharger. Is that possible?

During interstate driving and under light acceleration, I commonly see 2-3 lbs boost and the car goes lean while in closed loop mode. Does anybody know what is causing this? Any help or ideas would...

I've been reading along but I haven't the experience to help. I am struggling with spark on a sc 5.7. Cam timing looks like a major hurdle.

Post your tune and somebody here will chime in.

I'd be interested in Dodge tuning books. The only literature I have seen is pricey.

The o2 sensors disabled were likely downstream due to cats removed, (which would absolutely fail an emissions test). If it's running closed loop, the upstream sensors would need to be working.

Setup the wide band to log with VCM scanner. Hopefully, your wide band controller has an output and the cord. My wideband cord was a db9 connector so I had to get a DB9 to USB cord.

Disregard my previous mention of the bypass valve. The ecm may need programmed for the new injector size.

Yeah, that setup when new utilized the original 19 lb/hr injectors. The piggyback controlled the additional 100s on top. With 40s it should work fine but the map sensor will need upgraded and...

If I remember correctly, that setup originally utilizes a Kenne Bell supercharger with 2 additional injectors and a piggyback pc. It sounds like you've deleted the piggyback? I'm pretty green in the...

Does anybody have thermostat issues? I use a 180 with my Kenne Bell and the thermostat just died at 10k miles and caused an overheating issue. This isn't the first issue I've had with thermostats. My...

That just seems way too rich for a na engine. What's your thoughts?

I'd like to learn more as well. I've read some of the older threads but they were way over my head.

I'm new to tuning. Does that power enrichment look totally cartoonish to anybody else?
