I just burned another chip moving the injector constant to 24.5... lb/hr @45psi. On a short trip through town, i recieved BLM's of mostly 116-120 but yesterday on my way to work i got BLM's of 108-116 the whole trip. I was using the smae chip, but had fixed an exhaust leak, and an airflow restriction between my drive in town, and the trip to work. I thought that this would have helped but it appers to have made it worse, any ideas? my fuel pressure is 42 when keyed, and 38 while idling.

Thanks in advance

 

what ecm again ??

 

its an 89 350 TPI, 165 ECM i believe

 

Set the injector constant to what's in the engine.
Redo the MAF tables as needed.
Set the fuel to spec..

This changing inj constant to get things right is not the answer. While you might get the BL right everything else will get skewed.

120 ain't to worry about

 

I could live with 120, but now that my exhaust leak is fixed i cant even get 120 out of it.
I am confused Grumpy, i have heard you tell some people to not touch the MAF tables, and this seems to be a very contraversial subject. I have also heard you tell others to not mess with the Injector constant settings, so which is the correct way to do it?
I respect your opinion because you have been doing this for alot longer than most.

Also what things in winbin do i need to change so that Highway mode is enabled? i am running the ARAP.bin with the 6ev9 ecu, ( i think thats the name for the ecu).
