Looking for info from anyone that does emission inspections in
Massachusetts, especially if they have any experience with modded
vehicles, or input from anyone that has been through any
transmission/PCM OBDII swaps in Massachusetts.
This subject is probably nowhere
near as complicated as I'm making it
out to be here but I have a couple of PCM
swap questions that I can't
seem to resolve.
The project - Put a 5spd NV trans
in my 98 5.9 ZJ Jeep. I figure the
easiest way is to use a PCM from a 98 5.9
Done extensive Googling on the subject and done search/FAQ on about
two dozen Dodge/Jeep/Mopar forums. I've found out a lot but the info
always agree from site to site and/or I'm not sure if other
applies to the type of emissions inspections we
Just came back from
the place I got my sticker last time and he
couldn't answer all of my questions
off the top of his head because
he had never seen anything similar done. (my
vehicle is still stock
at the moment)
The answers to all of these individual
questions aren't as important
as the whole idea of whether it can be done or not
and how and what
actually comes into play.
So, the main questions:
1 - Do all
states have the same emissions/inspection requirements as
Massachusetts now that
OBDII is around? If not, what other states
2 - The emission inspection
machines in MA reads the VIN through the
OBDII port, correct? Does the tech also
have to manually enter the
VIN and/or verify that it agrees with the PCM VIN?
- Any CEL/code will automatically fail a vehicle through the
If a vehicle has CEL/codes due to the missing auto trans is there
any option in
the machine for the tech to override or ignore the
failure that wouldn't really
apply since it wouldn't have the
automatic in it anymore?
5 - The best way
around this is to use the PCM from a 5.9/5spd Ram?
6 - Can a new VIN be flashed
into a used PCM or not? Chrysler dealer
says they can't do it but I'm not sure
if that's a "they won't
do it" issue or a "they actually can't do it" issue.
Someone said the "Enter VIN" option doesn't come up on the
DRB if the PCM
already has a VIN.
7 - If the VINs can't be easily overwritten, used PCMs
any value right? Maybe for use in non-inspection states?
8 - Do
any digits in my vehicle's VIN specify the transmission type?
(I don't think so)
If they do - Maybe I'm getting too crazy here -
does that figure of the VIN
actually have any input as to how the PCM
operates, or is the VIN flash just an
9 - Do any other scanners have the ability to overwrite VINs
10 - I know B&G charges $130 for VIN flash and $430 for a custom
flash. Is overwriting the VIN considered custom?
11 - Can my 5.9/auto trans PCM
be reflashed deep enough to eliminate
the "looking for auto trans" inputs? I
talked to B&G
about this swap but it was at about 4:59 on a Friday. I didn't
the heart to keep them there answering questions about a swap that
had them questioning my sanity anyway :-)
12 - Do the Ram trucks have BCMs and
is that a factor in this swap?
13 - The alarm/disable issue - (VTSS?) I've heard
the PCM from a
factory alarm vehicle can only go into another factory alarm
A "non-alarm" PCM can go into either one.
I'll try B&G again sometime
soon but figured I'd post here first
to see if anyone had any experience with
similar swaps in Mass.
Besides, I think most performance flashes are designated
off road use only" so they may not take these inspection issues
Like I said, so much info/so many conflicting answers. I know there
can be issues with the seatbelt warning lights and/or the ABS lights
say that's not a problem as long as the PCM has any VIN
number in it.
and bolts of the swap isn't that crazy but I don't want to
start buying parts
til I solve the last few issues.
Thanks for any replies - John
