i purchased a 7747 off the net, the prom says

DELCO
ABHC
7737

i read the prom into the system and it seems to read fine in tuner cat.

but how come it says 7737 on the prom, what is that? shouldnt it say 7747

 

that's a service code number for the prom. If you use a scanner is should say scanner ID 7737.

 

thanks...

i read the eprom with my burner and the prom id is set at 6671
thers some wierd values especially for the tcc

the mph to engage is set at 0 for all 4 values and the disengage is 99.6% of tps

[edit]
i just found out the ecm i have came from a truck with a turbo 400 tranny, no lockup..that would explain the wierd values
