Well, the "Hammer" had some low speed idle hunting issues. So I took it to "Throttle Works" in Boise. They have some knowledgeable people there who know the E-38 ecu pretty well. My goal was and is drivability. They use a Mustang dyno which usually reads lower numbers than, for example, a Dyno Jet. No numbers yet as I will enplane below.
I don't have final numbers yet as there are some issues. The engine is an LS7 from Schwartz. What I found was...
First, the fuel air ratios near idle were up and down near idle. That caused the "hunting and surging" I was experiencing. That has been corrected and now drives well.
Second, while under full load we had some knock. So he backed off the timing from 29 to 27. Still had some knock so he went to the knock tables and found they were zeroed out. Translation, no knock control. Perhaps Schwartz designed this tune as a race engine only which could justify zeroes in the tables. Now there is a question "are there any knock sensors below the manifold"? Now I get to take the manifold off to find out.
So if there are any other Schwartz LS7's out there, check your ECU tunes.
There a few more "to do" items before bringing it back for another dyno run. I'll post numbers when I get them.
