Engine/Transmission (1998.5 - 2002) Question for Blue Chip FMS users

[Big P]

When I select the drag race mode on my box I get the screen that tells me that there is no fuel cutout, which I know it is supposed to do. When I get on the pedal though, it will only fuel to the percentage that the street mode is set to 15%, 30%, whatever I have it set to. I was under the impression that when drag mode is set, it defaults to it's most aggressive settings automatically. Am I wrong? Do I need to set street mode to 63% so drag mode will go to 63%?

In short ... . yes. It fuels aggressivly



(Watch the led light on street mode @ about 40%. You will see additional fueling start at about 5psi when on the "More Perf" smoke setting. )



Do the same on Drag Mode



(Watch that LED again and the seccond there is boost it dumps fuel. The fuel being dumped is the fuel that you have had it set to weather 10 , 32 , 49 ... whatever)

Thank you Tim. I thought that if I had it on 15% in street mode that it would automatically go 63% when drag mode was selected, guess not. I'm just glad it's acting normal, I'd hate to have to pull the box out because of it's location. BTW when is the next dyno event in RI. Thanks to Torque This and a few other parts, my truck is FINALLY ready for some good numbers, I hope!

TMTT is correct. My box was acting up and defueling whether in street or race mode. Then my LED died. So, I sent it out to Chip at Blue Chip and he got it fixed and back to me in a week, no questions asked, and paid for shipping back.



Now LED works again and it defuels like it should. Now I just need injectors and a turbo to maximize the box's capability!
