>> If you want to email me I can send you instruction for wiring it up.

E-mail sent!

>> Open collectors will give you bogus lean numbers at idle and very low speeds. (...) If you have a muffler that you can slip on the collector, or add an 18" or so extension, you will get accurate air/fuel data.

I might be able to steal the Borlas off the Dust Devil (my bracket car), or the old collectors with the Dynatech cone collector inserts may slip over the existing collector...

>> What are your RPM break points in your maps? I use 500 RPM.

300 in some spots, 600 in others. Trying to distribute things to where (I think) I need the most control over things, like around staging/launch rpm. Haven't done it yet, but I'm thinking it would make sense to narrow up the steps in the bottom 5-6 rows to better handle staging. Even in the burnout, I don't see more than 50% TPS. Wouldn't figure you'd need a lot of fine tuning control from 50-80%. Now, does it interpolate between the blocks, or is it a rigid cross reference chart?

I've been printing out my fuel maps so I have easy reference to past setups & trials. You'd think they'd have a print function.

I've been doing a screen capture, dump it into MS Paint, and printing from there.

>> AlphaN cranks in the lower left Cel.

That makes sense. Wish it would say that implicitly somewhere in the manual. Yah, I had it at 25. I'll knock some out. Thanks!

Used to spend a lot of time back in the day playing with tuneups on cars in Burnout: Player's Choice Edition and the IHRA Drag Racing game. I enjoy this stuff. It just went a little quicker and easier when it was all on the computer!
