That will be a plug- in chip. The flash memory boxes are at least part cast alum. If you want to get me the fore letter I.D. Code from the top of the factory Memcal ("chip") I will see if I have any info about it. That code will be four Capitol letters beginning with an A, B, or a C.

Robert how much have you experimented with what you are launching at? Once you get the drag radials on there you will have to find that sweet spot between spin and bog. Take good notes and log everything you are doing.

How are you tracking the weather when you run?

Ed,

I'll jerk the computer out in a couple days. already locked the garage for the nite. Got to get up early for work. May have a towing job after work tomorrow. What can you do to these ECM's? Replace the chip? Is the number on top of the box or do I need to open it up?

Nick,

Yes, we've played with different launch methods. This car launches like a turd. 60 ft times are in the 2.5 range. Like Tod mentioned, it was cooler and much less humid this past weekend than it's been when we've previously run the car. First time we've ever experienced tire spin!

Honestly, it doesn't seem to matter whether you stall the converter or leave off idle. It seems to run the same ET's. We don't have a weather station, we've been tracking the weather through a smartphone. Yes, we have been keeping a logbook. Will confess, we didn't take good notes this weekend.

Yes, am sure the DR's will change the charactor of the car a bit, I hope.

Just change the chips. No lap- topping at the track. open it up. Should just take a 1/4" nut driver to get the access cover off. Code should be right on top of that light blue plastic part.

Ed,

Pulled the computer down. Are these the numbers you need?
