You're usually more subtle with your attacks, Dan.
The FAST XFI worked well when I first installed it, but it all fell apart suddenly when I was working on retorquing the head on the LH side. It might be my injector harness, or an injector coincidentally went bad but it runs like a totally different car now that I replaced the injectors. As I suspected, I'm pretty sure I was tuning around a mechanical problem. I'm going to cautiously call it fixed.
And yes, I do have the day off. I plan to spend it with my son, dad and brother in the garage like I do every year (once we're done with the obligatory eating and drinking). We have 9 GM vehicles between us so there's always something to do.
Enjoy your day!

My GM vehicle sits in the garage at dad's with no engine. We can stand around it later and drink beer though. Should be fun.

We can take turns sitting in it and making engine and tire screeching sounds though.

like I said before.. Fast isn't for EVERYONE.. to me most people are "maybe " goin to run 10s.. TT chip can do it easy and ya don't have to worry if your mother in law jumps in the car to run an errand
BUT the Fast systems have a LOT of nice options for the racer I just ripped a tranny out of a TTA.. I am DONE for the day unless curiousity gets the best of me and I go out and take the trans apart I have to go and build a all billet roller 2004r for a 455 Pontiac 78 Grand Prix that runs 11.00 on muscle loaded with A/C.like I said before.. Fast isn't for EVERYONE.. to me most people are "maybe " goin to run 10s.. TT chip can do it easy and ya don't have to worry if your mother in law jumps in the car to run an errand
I originall built the turbo 350 that is in it 21 year(not a typo)ago and it still flawless,But he drives to the track 2 hours and want s OD.

Since it's idling in closed loop, and I rescaled the VE table (see, I can pay attention) it's at around 13:1 where it should be, in both drive and park. The problem was the same as with the stock engine management - the RPMs drop violently when I drop it into gear because of the small diameter converter. I can, and have, tune around it with the FAST. I moved the RPM on the table down lower and made the jumps between the MAP values tighter (5 kPa) at the bottom of the scale.
With the alky on the DC duty cycle only gets as high as 40% at WOT at around 70 MPH. Now that the MAT is in the right place I can see when the alky comes on. Pretty cool.

You know you will. It's a primal urge.
I rebuilt the front end of my son's RC truck with billet parts this morning. We're going to see if we can't break it after dinner.

Cool! The first and last time I saw Otto was at Atco. He organized a track rental and it was awesome. If I had more $$ I'd do it more often.
Jim
HAHA,If I had a running car I would do it more often.
I hope to be doing one in the spring from a tuners stand point,
Well unless my car is running.I still have to figure out what path I am going.

Nah, I still have the factory ties at each injector. No room for error. Each one is plugged into where it was before.

The clutches in my rear finally packed it in that day but I ran it over and over again anyway. Had the whole track to ourselves - had to take advantage.
Friday nights at Island used to be like rent-your-own-track night but it's starting to get crowded. Me thinks Atco will be jammed up on Saturday, too. But it'll be fun. My 7-year-old son loves to hang out at the track.
