Memcal interchange
Memcal interchange
I'm running a 7060 ecm in a 1992 silverado 3500 it has a AWUF bin.
I've been using a Moates memcal adapter with a custom chip I made.
I want a spare memcal and all I could find was one out of a 7060 ecm with a BAMM bin. I know this doesn't matter since the memcal adapter bypasses the chips calibration but the circuit board on the opposite side of the chip has a different number on it, does this matter?
I haven't read the calibration of this memcal yet but if it is the same or close to my stock memcal would it hurt anything if I put it in?
PS I was using the stock memcal for towing and a custom chip/moates adapter for empty driving, my original chip has no sticker over the eye, when I took it out this morning I think the sun erased parts of it because a lot of it reads blank now and it runs in limp mode. I burned a new chip with the stock cal. But I'd still like to have a memcal that will work without the moates adapter.

Re: Memcal interchange
you may be able to leave it in the sun for a an hour or so to completely erase it & then burn the bin back to it.
a few years back those were the only chips anyone had to work with & thats how some people erased them.
i would see which bin seems to work best before trying to burn to the stock chip, if it works you may only get 1 or 2 chances before the chip gets fried.
if you do get it to burn, put some black tape of the window to prevent accidentally erasing it again.
from what i can tell, BAMP shows to be the latest update for AWUF.
BAMM shows to be the update for AWUC.
but it looks like BAMM will work.
this is shown for 1991 for BAMM,
C-30, trans MT1, axle GT4 3.73 GVW 10,000 & GU6 3.42 all GVW
for BAMP in 91,
C-30, trans MT1, axle GT5 4.10 HC4 4.56 & GT4 3.73, GVWs 10,000 & 11,000
for 92 they both show to be used with the same axle but differant GVWs, 9,000, 9,600 & 10,000 for
BAMM.
11,000 for BAMP.
i would guess there is a small difference in ignition timing, TCC lockup speed & maybe shift points between BAMM & BAMP.
my guess is BAMP locks a little later & is a little slower on timing advance.

Re: Memcal interchange
Thanks for your reply and info.
When my stock AWUF erased I just burned it to a chip and used the memcal adapter.
I did find a BAMM the other day, and a BAMP today.
As far as I can tell using TunerPro RT and Moates APU1 there is no difference at all between the AWUF and BAMP. The BAMM does lock the tcc 1 mph sooner and unlock 2 or three mph later than the other two.
Is it possible there are other differences that I can't see with my hardware/software?

Re: Memcal interchange
no problem
from what i understand, BAMM & BAMP both raised the trans hot mode temp from 252 to 270 degrees F, changed the decel fuel calibration, & changed some idle perimeters so it idles in closed loop to help reduce cat converter odor. the change for each is in relation to their preceded bins.
there should be other differences between BAMM & BAMP.
the Difference Tool in TunerPro should show whats different, but what each thing does may not be defined in the TunerPro def file.

Re: Memcal interchange
i have access to All Data. i think you can get the info from auto zone or maybe a GM dealer.
here is where its at in All Data & how to get to it.
Diagnosis & Repair, then PowerTrain Management, then PROM section, 1 part is in TSBs, the TSB number is 922366E, lack of power at hiway speeds.
this is for checking for updated PROMs by scan ID, Prom code, Prom Bcc, ID, or part number.
its also in the PROM section, then Application & ID, then "2 additional entries", then 1992 7.4 VIN N. then find the PROM # & click the box to check for updates.

Re: Memcal interchange
I am looking for at least a AWUF/BAMP memcal/prom ( I'm new to this type of GM mess ) or moreso a complete ECM with one of those proms or even someone who can burn one for me.
Any help will be appreciated and yes, I have read a ton in these forums and have downloaded the files for them and push comes to shove I will buy the Moates stuff and make one but not sure I want to do that if I can avoid it.
Thanks
Dan
