hello, have few questions about this engine that friend of mine bought the truck with,
1.cannot connect to ECM with in site , tried weather connector also , can connect with jpro(using diagnostic port) and it recognize engine and all parameters on engine
if i connect to weather connector with nexiq 2 it sees engine on datalink
2. truck runs with oil temp around 230 and up to 250 on hills , read some comments that ts normal for this engine but there is a little talk about replacing oil thermostat from 220 to lower one
3. its low on power , as far as my friend say it boosts only 20psi ,
any thoughts appreciated

high oil temps like that is NOT normal. Something is wrong. Likely timing not set right, or excessive boost, either of which is causing too much internal engine friction and shortening engine life.

a lower temp oil thermostat will only serve to hide the issue.

adapter needs to be set to J1708 to talk to ecm.

tried to set it up to 1708 on in site but there is only autodetect option
cannot setup adapter to that setting , assume it just recognize datalink on 9-pin connector
im using nexiq 2 connector but have also nexiq 1 and inline if if might help me out
recently i connected to a truck with n14 but engine was 2020 reman with M11 ECM , assume a glider truck , 9-pin no work gray connector on engine harness also no work but weather connector worked for me with in site,
