    Thanks. It needs a lot of tuning. Turns out this engine has pretty low vacuum. It idles at like 60-65 KPA. I have been wondering if there is a way to know for sure which VE and Timing table you are using. I know there are a few tables that use TPS and MPH to change to the off idle VE, and open throttle spark tables. I am trying to make this as simple as possible. It seems like its going lean on part throttle and WOT throttle. I am wondering if its even moving into the off idle VE table. It using stock 350 injectors so I know there should be plenty of fuel.

    There is no VSS so I have that disabled.

    If I get it somewhat lined out, i was going to try running it in closed loop. I have an 02 wired in, and also the engine temp is connected to a remote oil filter. Right now its in open loop only.

    he is getting ready to drop it off at my house so I can take my time with it. I have been running out to his house for a couple hours a night and just cant get anything done.

    He made the distributor. Its a Corvair and 4.3 V6 hybrid. I will try and get a picture of it.
