I am thinking of putting an non egr intake on my 89 TBI. If I set "Disable EGR if MAT < X" to some number like 350 degrees would this prevent a code? I am thinking this is the easiest way to convince the ECM not to turn on egr.

Thanks!

 

Yes, that works. Except that the TBI ECM ('8746) it is by CTS, with two entries to change.

In $8D, there's a switch you can throw to disable the EGR diagnostic in addition to setting the enable values to something impossible. Not sure about the 8746 though...

 

Hum, MAT and CTS? What is the second parameter? Closed loop?

 

There are two coolant entries that need to be set:

Since it is the inverse temperature setting them to 0 is 150* C.
