What was the trap on this pass?

 

Stage 2 map for the current firmware is the current stage 1 map.. However with the release of the new firmware, closed OPEN fuel control has a "Background" map already optimized for the stage-2 exhaust.. the remaining portion of the map contains some timing and boost optimizations.

 

Is the release out now? And will it affect the tune I have now? I had a dynoflash on the fuel map and zeroed out the fuel map on the UTEC for the stage 1 map.

 

looks like the release code will be several weeks more.. I'll e-mail them and find out whats going on (I've been running the beta code for several weeks with a few minor issues that will be resolved with the release)

Ok, lets see if I can explain this without confusing anyone.. If you leave the fuel control as default, it works the same as it does now, therefore your maps will have to be re-loaded, however they will work as they did before.

If you ENABLE open loop fuel control, it takes over for the ECU Completely, so the dynoflash will have no effect on the tune, the background map basically gets you "in a zone" so your car is running and you don't need to set injector duty cycles directly to get it running. But you basically have a new "Stage 2" map in this mode.. in my case, it was a little lean for my needs, so I added fuel in the ranges I was lean. It works really well, since it takes over for the ECU's fuel control, you no longer have fuel cut, or rev limits enforced by the factory ECU, and you can set it within the UTEC.

 

Strangely enough, my dynoflash removed the rev limiter and fuel cut already. At least thats what I am understanding.

 

Exactly, but with the new software if you have a utec there is no point that I see to need a flash.

Too bad to hear the new release is still weeks away. I really want to get my car dynotuned on the latest release.

 

I think he was at 106.

 

reaction time has NOTHING do to with your quartermile time. from what I read above, I am not sure you understand that.

106-107 traps are definitely good for mid-high 12s. work on that 60ft and you'll be down!

Raction time gets you beat even though you run a quicker et. That is what happened the first time Chris raced the Cobra.

 

if your racing.... but if your looking to better your TIME, reaction time means nothing. I come across people ALL the time that still think if they get the r/t down from 1.0 to 0.5, they'll run a 12.5 instead of a 13.0.... thats not the case.

if you run 13.0, you'll run a 13.0 no matter how long you sit there after the light goes green... there is a limit, but you get my point.

my posts are directed to the 1st couple posts in the thread...

We both sucked at reaction time and launch. I couldn't get near 2.0 for a 60 ft time or 1.0 for reaction. I've got a good .5 sec in my 60 ft time if I can figure the launch. Then, if I can keep from missing third, I probably have close to .5 second there as well.

It was great fun though and we plan on going back soon.

 

Have you ever heard of a whole shot win? Reaction time is very important! Anyway, it doesn't matter...a Cobra owner went home a loser!

If your racing... I on the otherhand was referring to your original post:

Here you made it sound like you felt if you reacted better, you would have gotten a better 1/4 mile time. I am just stating thats not true. Its a VERY common misconception...

Anyway, do you mind posting up the slip of the run for both you and the cobra? Just the numbers. I am curious to the details of the run.

I can try to explain what you are saying. In other words reaction time has nothing to do with E/T's. You could just sit at the light for 5min or until you are ready to move. Once the front wheels move forward, then the clock begins. A bad launch can make your ET lower just because of turbo spool.
