Re: EBL Flash Rich Idle

2nd what Buccaneer said. I've got the Aeromotive 13301 model and it works great. What are your mods btw? What you'll need might greatly depend on that. For example, I thought that my engine...

Re: EBL Flash Rich Idle

Yeah it's been a while, but I was able to stop the surging by doing quite a few things. Here's what I did:

1). Increased the idle speed. My truck runs at 550 rpms at idle, stock. I increased...

Re: Tuning with the EBL

Yeah I guess it got cut off in the picture. What you're seeing is the low speed VE table 400-2000 rpms. Yeah that's a good point - I forgot DFCO activates when coming off the pedal, which...

Re: Tuning with the EBL

Yep, you're correct - I'm running TBI. That's what I was doing when I was still in open loop as a matter of fact. I would do a few learns, then I'd have to smooth things out...rinse and repeat. ...

Re: New VRFPR, Crazy VE Table

Yeah it's pretty wild. I'm still in the process of tuning, but for the longest time, I just thought I hit a bottleneck at 4400 rpms. Not that I have a radical cam or anything, but I thought it...

Hey Tom,

Using the vrfpr, I was able to for...
