I am pretty sure you need to remove 2 degrees from the wide open throttle timing menu which I believe is in percentages no degrees.

not available with the u7146

Troy,
I want to know if I can still down load the Diablo canned octane tunes to the unit without going to the latest revision. no
What to I stand to gain from updating my 7146? More performance
What all do you lose when you update and is it reversible? You will lose the OBDII menu options, disable ...

U7146 will work for your Mach 1

Is the 01 Cobra a premium only vehicle? my Mach 1 is and I only have a 93 octane tune.

no luck i am guessing thanks for looking

Would you have dyno sheet stock vs tune for a 2003 Mach 1 with the 9r07b tune?
Thanks in advance!

Data log your timing 4th gear pulls at the track from 2k -7k 2k-4k 4k-7k rpms are adjustable. You will need to take your laptop to be able to reload your custom tune as I would log both. Since you do not have a off road mid pipe there are no cel light to worry about running v.9r07b. From what I have ...

before using the Predator tune make sure you save the custom tune to your pc or you will loose it.

Without a Wide band o2 sensor and a separate data logger all you can adjust is timing with a manual trans.

Ya,,I'm one revision back from the current one that takes away the rear O2 control.

Cool,,,I have a full tank of 93 in there now.

Is there any 'common' tweaks I can do to this 93 tune? WOT fuel?,,timing? ,,,or just leave it alone. Car is running great currently, but hey if I can squeeze more out ...

...also - I'm one software revision old,,I like being able to delete my rear O2's.

Does the latest version of software make ANY tuning adjustments (I guess I only have the canned 91 tune now,,but compare that to say the 'new 91' tune in the latest version). Is there a power difference/impovement ...

When I first got my Mach 1 like most people you want to tweak the most out of it. Being a old school drag racer I have a 66 Chevellle that runs 10.60's with a smallblock no power adder and this was 20 years ago http://www.youtube.com/watch?v=G1DnadY2cSk. These guys here know way more than I and ...

So you took out 10%, you would think that would have been enough. You still should have 10% left to retard at WOT. The ranges for our tool is 10% advance and 20% retard if I remember correctly. Data logging should be in 4th gear from 2k-up at the track since doing it on the road is dangerous and ...

i usually get gas from about three different stations,but is possiable that they all have crappy gas, fuel filter is less the 6 months old so pretty sure thats not the issues, and as far as unmetered air it should affect the car when not running the tune, same as far as low fuel pressure and egr ...
