Good to see you out there yesterday Rich. The car was running like a xerox machine. Look forward to seeing you in Vegas at the Q16. Should be interesting to see how the car runs with the DA there as well.

Thanks Al. I should have used a little more timing too. Maybe next time I'll kick it up 2 degrees.

There wasn't much to the tuning part. * I changed the fuel energy constant in the software from 1.0 for gasoline to .438 for Methanol. * I changed the injector size in the software from 83 lb/hr to 160 lb/hr. * I made a few passes and adjusted the WOT section of the VE table to get the closed loop correction factor below 5%. Since my fuel pump and lines were already up to the task of handling alcohol at 2.2 times the flow rate, the hardest part was actually changing the injectors, and I had to swap out one of the fuel filters because paper filter elements will not hold up to alcohol. All in all it was pretty easy. Some of my buddies were concerned that it would be hard to start, but that doesn't seem to be the case. I guess when you inject right at the valve it fires on the first crank. Can't wait for MATS!!!

That Hemi looks in your dragster. I have the Ron's terminators on mine,have to prime it when cold but after that cranks fine. After its warm it cranks fine but due to the tank being lower than the injectors and manual fuel pump,you have to be ready to keep it running when its first fires. Mine does not milk the oil either. They tell me the VP M5 is the Hot Ticket now running alcohol,plan on trying some this season. Forgot to mention mine is a o'll wedge,always wanted a Hemi but looks like I will never be able to afford one.

nice gain do you have some more info and maybe pics of the injection system?
Here's a shot that shows the fuel rails and the throttle body. Nothing very different from a street setup except the throttle body is a 4500 style.
One thing that is different from these pics is that I replaced the fuel lines with Teflon lined braided steel lines. NHRA said I had to replace the nylon braided fuel lines on any higher pressure EFI system, so I had to change them anyway.
Here's where I have the ECU(s) mounted. The XFI is the main ECU and the XIM, on the right, controls the ignition coils.

Rich, you may want to try a couple less degrees timing. Alky likes a touch less than gas. My 528 wedge likes 34*. If you get a chance, would love to hear results.

I'll go both ways at the next race and let you know. I'm at 33 right now and the plug burn is perfect.

Rich, don't forget you are knocking on that advanced ET door too. Not that it is a bad thing
Good point. Oh well, I'm legal.
