Brian,
Can you please pass the following words on to the GB guys...

Hey guys, I wanted to update you with what's going on and what to expect in the
near future. Thanks to the couple of guys who've sent in the dyno runs and A/F traces;
they're helpful.

Some of the cars are leaner without the Unichip installed in them than the cars we
saw here and what we're looking at another car to see how it compares. We just got it
today, and it's just like the other cars we saw here previously. We're also looking at
how the stock ECU responds to water and air temperature both on the road and on the dyno.
Right now I've seen the dyno's for 3 cars running a bit lean and 3 other cars running
absolutely perfect, and I want to figure out why. The first guy who found his car too
lean on the dyno got it retuned and, despite a worse 60' time and higher temperatures,
turned the best trap speed he's done... because of the Unichip.

Bottom line, whether your car is lean or right on as it sits, the Unichip is
permitting us/your tuner to move the A/F ratio where ever we want it to go. It's doing
what we told it to do; it's just that some of your cars are leaner than we anticipated
from what we saw on the development vehicles in "stock" condition - i.e. before the
Unichip is even installed. We/your tuner has the ability to make the A/F ratio go
anywhere from about 8 all the way up to 18... that's not a problem. The issue is figuring
out why the cars in question are reacting the way they are and making a logical, correct
change to the map so the problem is fixed.

The car we looked at again today, a GB guy who got a pre-programmed kit just like
everybody else, had a 13.2 A/F ratio which is exactly where we wanted it to be... and
exactly like the other two cars we've used. Again, we don't know why the cars in question
are leaner in stock trim but that's the entire issue. When we pull the "correct" amount
of fuel for the car's we've seen which are 1 A/F point richer than the cars in question,
it's making the cars in question 1 A/F point too lean. Making those cars 1 A/F ratio
richer is simple, but isn't the issue, and we want to know why so we're making the correct
change the first time out.

We can make the change right now, but what everybody should really want is the
right change. We know what "numbers" to change to get the A/F to the desired point, but
I'd like to be able to see if there's a rhyme or reason to which cars should get which
maps rather than panicking. In the end, you'll all get the map/A/F you want (at no cost),
but let's take a couple of days and figure out why.

Thanks again for your purchase and early next week we'll be able to offer you a
revised map if you should get one or if you want one.

Thanks Brian.

Cheers,
Jack
