Our Mustang Twin Turbo project has been put on temporary hold. Unfortunately,
a solid solution for ECM reprogamming STILL does not currently exist. If
you've been following our progress, you'll remember that we reached the limits
of SCT's Xcalibrator software back in January. Since then, we have been
patiently waiting for some kind of update. No such luck. If you wish
to be informed of updates, please send us an e-mail with your contact information,
and you will be added to our e-mail mailing list.

Over the past week, we've been tuning out the drivability
on the dyno with the help of our dataloggers, scan tools,
widebands, and SCT Tuning's XCalibrator (which I might
add is working excellent!). This gave us a good understanding
of the ECM's ways. Spark timing advances/retards, trends
of short and long term fuel trims, air flow meter readings,
etc. Understanding and fine tuning these play a vital
role in how well the car will drive day in and day out.
It's fairly simple for anyone to tune WOT. Cruise, stop
and go, and "tip-in" are generally overlooked.
Last night, we took our Mustang WOT for the first time
since the Twin Turbochargers were installed. It's currently
equipped with our Twin Turbo kit, stock air flow meter,
65lb high impedance injectors, ~3-4psi wastegate springs
(with wastegate dumps plumbed back into the downpipes),
high-flow cats, stock midpipe, and Ultimate Racing axleback
mufflers. Some might ask why we're using such large
injecftors. These are brand new 65lb high impedance
injectors by Siemens/Deka. The beauty of these injectors
is how well they work when pulsing low. They are fast
reacting, and work better than our 42lb injectors! Anyhow,
this test was to find the limitations of the factory
air flow meter. We already have an upgraded air flow
meter (which we will be testing next), but wanted to
try this first. Sunoco 94 octane gasoline was used.
Of course, we know that not everyone has the luxury
of 94 octane, we will be releasing some 91 octane results
shortly. The SCT Xcalibrator can hold 3 preset flashes.
We plan to have 91, 93/94, and possibly a race gas map
included with each kit. The kit is producing only 3.5
- 3.7 psi of boost pressure and we are rapidly nearing
the limitations of the stock air flow meter. We are
very pleased with the results.
