wiring diagrams show that manual transfer case is connected to the ecm pins 60,61 of x1 connector. seems simple , I did not see any selection for manual or automatic transfer case in vcm

OK got that , can I purchase a new ECM then use SPS to Replace and Reprogram my stock calibrations with my vin. this would then be my clone. I'm not an expert with SPS and it allows me to go pretty...

Hello Mark here, what I would Like to do is this: make a Clone of my existing E92 ECM using a spare ECM. I have tried to Replace and Reprogram a used ECM with SPS with a MDI and the VIN from the Used...

OK here is what I tried and learned. It appears that I can Reprogram an ECM with SPS but not change the vin.To do that you may need a special VCI code from the customer support center. a new blank...

O.K. I am able to read the new ECM with this cable the ECM draws 0 ma with power off and 280 ma with power switched on at 13.2V
next I will re-flash using SPS

pin 52 and 30 are associated with cylinder 1, you may want to use a signal from cylinder 2,3,5 or 8 as these cylinders are not AFM so the signal will always be present and never affected by AFM.

questions , do you have a NOS MINI 2 STAGE PROGRESSIVE CONTROLLER P/N 15974 and is your 2014 Silverado a 5.3 direct injection ? if so you may be able to connect the nos controller green wire to the...

here is what I found in the NOS MINI 2 STAGE PROGRESSIVE CONTROLLER
P/N 15974NOS Instructions

STEP C. RPM SIGNAL SET-UP – (This mode sets up the controller to work with the style of ignition...

that link is for a 99- 02 vehicle not a 2014 , what engine and ECM does your truck have? I'm assuming an E92 because this sub forum is for Gen 5

you can connect 4 diodes 1n4003 and...

here is the correct Schematic

I put +12V to pin 70 and could not read , I measured continuity between pins[X1 22. 26, 30, 53, 68] and [X2 pin 73] and [X3 pin73] they are all signal ground connections. I did connect [X2 pin73] to...

that is an LED to let you know that switched power is being applied to pin 51 and 73, simulating ignition on. I also tried putting +12v to Pin 70 (Accessory Wakeup) and current draw did not go to...

I just built a E92 programming harness , but I cannot connect or get the ECM to turn on. I believe my wiring diagram is correct. the ECM is drawing 26ma with switch off and 48 when switched on. I'm...

there is no tach output from the ecu , but there is 8 coil outputs this will give 1/8th of a tach/distributor signal. This wiring diagram is for the L83 engine (5.3 DI) . Also who makes your...

well I looked over the ecm pin out and thought I would connect a couple extra pins, add a bypass cap as I plan on using a regulated PS, and a termination resistor for High Speed GMLAN Serial Data 3....

when you say "system" do you mean that other modules have counters that record when the ecm is re calibrated?
I had a 2007 yukon xl 5.3 that at 76000 an AFM lifter collapsed and I maintained the...

thanks

my plan would be to install the doner into the vehicle then install factory calibrations , Well I am going to purchase a used E92 to see how it goes

is the VCM Scanner able to to read GMLAN Single Wire CAN 33kbps? such as HVAC module and such

thanks, but I'm a little too late as my engine now has a collapsed lifter

Hello, Mark here I just picked up a 2015 yukon 5.3 and I would like to swap out the ecm with a used one. Recalibrate it for my vehicle and then tune out the AFM only. I believe this is possible. I...

can the HP VCM disable Active fuel management on gm vehicles like my 07 Yukon xl 5.3?
