The Grid is pretty amazing. To bad it's allowed in nostalgia racing.
gregm784:
USB connection for ease of programming
Timing based on engine rpm and gear value
Advanced individual cylinder timing based on gear or time
Five retard stages for nitrous
Four steps of rpm limits for burnout, spool, launch and overrev
Output switch set on rpm, pressure or time
Shift light settings for each gear
Ignition data acquisition accepts multiple runs
Crank Trigger system highly recommended

BTW, when some of the teams A/FD Heritage switched to the Heritage TopFuel tires [ 12-36-16] 1'st on M&H then M/T it improved the tire shake issue and now 2 teams have run in the 5's.
These "Bubba" tires are very stiff sidewalls, don't grow much and are real heavy, like 70 lbs with wheels, BUT they sure work.

concerning the bubba tires, they have used this theory in the door car series such as 10.5 and 8.5. run on rims that are usually about 4" wider then the tire. this why i asked the question in the wheelie bar thread. seems like everyone just does the same ole thing thats been done for last 60 years. even though these guys have big power for the size of tire, the theory could still provide bennies for lesser powered setups, even feds. hence controlling tire shake with little hp and big tire in addition to wheelie bar height.

ive messed with msd programmable 7 a bit before jumping into EFI. the grid is basically the Programmable 7 without ignition capabilities, meaning all the control is still there and now MSD made it so it is modular for other dizzy's, mags, etc. which is awesome. There is a lot you can do with the GRID. timing is primary, control slew rate..
id love to use it in this type of racing, there would be a lot of benefits to using it. would be nice to have a 2 step on the launch and mess with timing a bit down track. but, im an electronic type of person. i get the 'purist' aspect of the racing.. but this is 2017.. just like nascar went to EFI finally after gazillion years.
