So I've been doing some logging runs with my new wbO2. It seems like the program on the sharktuned fuel chip leaves a lot to be desired. That one dip that goes below 10 bottoms out at 9.6:1. At least it's not dangerously lean anywhere though. I'm going to try to use Andrew's cool spreadsheet LH editor to smoothen out those valleys/peaks and also try to keep the AFR level at 12.5:1. Thoughts/comments?

What type of S/C install, and who produced the EPROM ?

 

The way "that guy" talks and the idiotic things he says, he can't help me worth a damn. And anyway, I wasn't asking for help, just comments, like if maybe someone has used Andrew's LH Edit program to do something like this. I know exactly what I need to do to. I already have the correct UV eraseable chips and a suitable EPROM burner. This isn't exactly rocket science. And yes, even with this sub-optimal AFR I still get an awesome torque curve.

Thanks for the heads up though

This is one of the Andy K. kits with an Eaton M112. It is Sab's former car. I believe the chip came from Cameron's GT that had the same kit installed. So strike one is that this chip was made for another car, albeit same model year with the same modifications.

Dan,

Did you ever fix that colapsing intake hose?

 

That is also on my list of things. I haven't decided whether I will cut a hole in the pass. fender or try pulling air from both of the fan shroud openings. I really don't like the idea of cutting such a large hole in the inner fender structure.

I would for sure address that first. That thing was choking your air flow on the dyno with the hood open so I have to believe it's even worse when the hood is closed and you are under boost.

 

That's good. It shouldn't take you long at all then to properly fix what's causing the air/fuel curve to look like that in your dyno chart. Good luck.
