I WILL BE ON VACATION: May 30th
to June 8th. ANYTHING received AFTER May 30th will be done after I return.
PCM Reprogramming Services - PCM
Programming service for your engine swap project or stock vehicle. I program
all swap PCMs to remove anti-theft
system that will cause a "start and die" condition. Sometimes this is referred
to as VATS. I enable cooling fans for all swap applications, and change fan on
and off temperatures. I can adjust for different
injector size depending on if I have the data for them. I can program for
different transmission options as well I WILL NOT be able to offer
custom tunes for modified engines. (aftermarket cam, boost, heads etc)
I do not lock any PCM I program, and will be compatible with popular tuning
software after I am done. You can select the payment option for your
application below, but please be sure to view additional info for your
application on the right, and read on below the services for
details I need for
programming for swaps. Write down info include with PCM, or email it to me
STOCK Vehicle needing anti-theft deleted due to start and die condition.
See Details Here.
I have gotten a lot of questions if I
was still doing programming, answer is YES, I have not stopped doing
programming, nor do I plan to at all. This is my full time job. LT1SWAP.COM was
created in 2002. 16 years later I'm still here! Thanks, Brendan -
5/12/2018 - The work coming in the door takes top priority, followed
by email/phone calls. 3-5 day turn around right now. Shipping address at
bottom of this page.
*2007 was a change over year. Early production was a Gen3 engine
in the "classic body style truck" 2007.5 was a Gen4 engine in the "new body
style for 07" ADDITIONAL PAYMENT OPTIONS, SHIPPING OPTIONS AT BOTTOM OF THIS
PAGE "BUY NOW" BUTTON. PRICES INCLUDE ME SHIPPING THE PCM BACK TO YOU.
Engine Type & Year: Please let me know if PCM does
not match the engine exactly. GM used different injector sizes, fuel rail
types etc across engine's and years. It's important for best performance
to know exactly what the engine is. Also, if you plan to swap
intakes from another engine (LS1 intake on a 5.3L vortec) I NEED TO KNOW THIS.
Supplying an 8 digit injector number found on side of each injector will always
help insure correct flow rate is programmed into the PCM.
Engine Type & Year:(LS 4.8/5.3/6.0 LS
Engines: Is your fuel rail a
returnless type, (using corvette regulator) or does it have a vacuum
referenced fuel pressure regulator? What is the injector part# for 99-14
4.8/5.3/6.0 see here for details...)
4.8/5.3/6.0 LS Engines: Is your throttle electronic? (DBW
- Drive By Wire) or is it mechanical (DBC - Drive By Cable)
Transmission Type & Year: I can
disable automatic trans diagnostics if you wish to use a TH350, TH400, 700R4 ect.
Please read on below for info about the Vehicle Speed Sensor (VSS) Also
please let me know if you will run a MANUAL transmission, this is to ensure
proper idle control. Some engine / trans combinations were not offered
from GM every year. I can also do segment swaps if your setup is a combination never offered from GM, some
additional local tuning maybe required to get everything "just right" for idle
behavior with manual trans. A good example would be a drive by cable 2003+ truck
engine with manual trans.
Rear Axle Ratio/Tire Size-Height: When using electronic transmission,
this info is only needed if you need a calibrated speed sensor signal output to
run a stock type speedometer. I can program the PCM in most cases to
output the proper speed signal to use the stock speedometer in 88+ GM Trucks,
Jeeps, etc, about anything with electronic speedo from factory. Most of
the aftermarket speedometers are programmable, and the output from the PCM does
not need to be exact.
Remove Emissions? (this includes EGR, AIR
Injection, EVAP System, Rear Oxygen Sensors on 1996+) You may choose to keep EGR
but remove the rest. Let me know and I can keep what you want.
Typically If you say remove emissions, I remove them all. Keep in mind, I
only disable the diagnostic test the PCM performs on these components. If you
keep them hooked up, they will still function, with exception to EGR. EGR
operation changes ignition timing, so If I disable it, it will not function at
all. (Things like MAF sensor, MAP sensor, Front Oxygen sensors should always be
retained and used and I do not remove.)
Is this an Engine Swap, or original Engine/Vehicle. (some
things I disable in the computer has to do with the PCM communication with other
devices in the original vehicle. If PCM is staying in original vehicle,
its important I know this.)
Mass Air Flow Sensors (MAF canbe
removed from most vehicles if required, however I recommend using it if at all
possible to improve drivability) LT1 vehicles had two different size mass
airflow sensors. The Caprice and Camaro units are different size. Also
98-02 Camaro/Trans Am LS1 used a 3 wire sensor. Truck 4.8,5.3,6.0 all used
a 5 wire sensor. Yet there is also a difference between Truck and VAN
4.8,5.3,6.0's. So if picking parts from different applications, keep this in
mind, and LET ME KNOW, programming is different for each type of mass airflow
sensor. I can also adjust for LS3 card style MAF (may require local fine tuning)
Cooling Fan Controls I enable cooling fan
control on ALL SWAP programming with basic on/off points based on stock engine thermostat temps. It will
not hurt a thing to have the control there, but not used. If you use a lower
then stock thermostat, let me know and I will adjust the temperatures
accordingly. PCM Supplies GROUND to activate fan relays, MUST us a relay. (1996
4.3/5.0/5.7/7.4 PCM's DO NOT support FAN CONTROL)
VSS - If using a non electronic trans such as TH350, TH400 or
a manual trans, you should KEEP a vehicle speed sensor
when possible. The PCM needs to know if vehicle is moving.
Without the speed sensor, you can suffer from reduced fuel economy, reduced
power, and idle problems. There are a few options for speed sensors on the
transmissions with cable drive output. View this link at
Dakota Digital website. I have used Dakota Digital SEN-01-4160 with good
success. This is a 8000 pulse per mile sensor, that will allow cable
speedometer hookup. (SEN-01-4160 WILL NOT WORK WITH
DRIVE BY WIRE CRUISE CONTROL, Dakota Digital SEN-01-128 should work for DBW
cruise.) I can program most any PCM to accept any # of speed
pulses. Also check out www.jagsthatrun.com for
other speed sensor options. (Must output a SINE wave signal, or A/C Voltage)
4X4 vehicles and ELECTRONIC
TRANSMISSIONS such as 4L60E or 4L80E - It can get tricky with 4x4's and electronic
transmissions. GM applications with 4x4's always put the speed sensor on
the OUTPUT of the transfer case. Then there is a signal to the PCM to tell
it when you are in a LOW range, so it can adjust the shift points. (shift
points are based on MPH in all GM computers) If you use a LT1 engine, there IS
NOT an option for low range input and
you must have speed sensor located between the transmission and
the transfer case.There are aftermarket companies that offer an
adaptor that fits the sensor in this location.Anytime you use an
electronic transmissions (4l60e, 4l80e) it is best to keep the factory 40 pulse
per driveshaft revolution speed signal. It is possible to use the above listed
SEN-01-4160 but that would require the drive/driven tooth count of your speedo
gears. Check Novak Conversions
or Advanced Adapters
for information on adapting transfer cases to 4L60E and other transmissions.
These adaptorsinclude a speed sensor.
you have a TH350, TH400, or manual transmission, 4x4 or not, then it really doesn't matter
where the speed sensor is located or the # of pulses, just so PCM knows vehicle
is moving, as stated above. Keep in mind I need to know
# of pulses and tire size/gear ratio when programming.
Please include your return shipping address and phone number, email address,
INSIDE THE BOX. If the PayPal payment comes from a name different than what
is on the box, it makes it very difficult to identify who its from.. Below is a ''Buy Now'' button you can use to send
a PayPal payment to me, or you can include a money order with the PCM when you
send it. Expect 3 to 5 business day turn around time* (up to 5
days possible if work load increases). I ship with US
Postal Service Priority Mail with tracking. If you require delivery with another
service, please let me know. 1-2 Day USPS Express Mail shipping is available. It
may not be overnight to some zip codes. See the
dropdown box below.
Thank You... -Brendan.
