Edelbrock bank to bank split on short terms

[TheSlow1]

So I'm working on adjusting my tune and ever sense I got my car back I noticed that there is a split in the short terms at idle and when the car isn't in boost and at very very light load while cruising. Wondering if this is because of the design of the edelbrock kit and I need to adjust and one to have a little more fuel for it or if this is an actual problem I may have. I havnt found any vacume leaks or any other mechanical issues an I've heard about things like this on Kenny bell kits so in thinking it may be the same type of issue.

Please let me know your thought or if you have experienced the same issue with your edelbrock kit

What are the ltft and stft at? KB has an issue with the bypass valve location blowing into the #5 cylinder.

I have my ltfts turned off and my stfts show about a 16 point split between the left and right while at idle. Bank one usually reads 1.08 an bank two about 0.92. I've been tuning down the middle when I have splits like this but I'm thinking I may need to add fuel to one of the banks during these situations to get it all straight.

That's an even 8% on each side as you know. Have you tried holding the bypass closed and reading trims? The obvious answer would be your o2 sensors are crossed but if it was all good prior to the supercharger install that wouldn't be it.

It's an even 8% because I tuned it to that. I know the o2 are not crossed because I confirmed with a wiring diagram. I know whenever my bypass is closed and I'm at medium throttle the trims are very very close to eachother like within a percent of eachother. So I'm really leaning towards it's somthing to do with the bypass but I'm trying to find out I'd anyone else with a edelbrock has the same issue or if they are aware of it being tuned out

You should contact lito. He has mastered my eforce JUNK!

Might have to do that

its the bypass and the cams... use a wideband to see which bank is reading closest to actual afr and tune off that one...its a common problem
