Is there someplace out there that has injector offset charts? Think I have found the issue of getting my tune dialed in. They are a set of Holley 50 pounders high imp, but was talking to someone and he thinks they might be Bosch type 3's. And they have some funky offsets. I've been working on that and have ADDED .250 across the board for the injector offset (worked up to that point),I had tried subtracting and it made it run richer. I have it locked into open loop and the idea was when the offsets were getting close that my wideband should get close to what I put in the table for an AFR command. Well it is getting pretty close. I did try .300 across the board and it started to go pig rich again. Gonna try .275 and work my way down and see if it gets any better. Any info would be appreciated. Drivability got way better was 15 mpg and just with the offset adjustment got it up to 20 mpg. Next gonna work on seeing how lean it likes it and not have issues. And I don't know if anyone else noticed this but in the open loop table at the 56 degree vs 20 KPa I have to keep that one cell at 13:1 at all times no matter what. If I raise it.......it will go above 20:1 afr. Just thought that was kind of interesting.

Not sure about Holley injectors, what is the pressure rating? it should be either 39 or 43 psi

Hey Moe, I talked to you like a month or so ago about getting you up to Michigan, couldn't any support drummed up for that and I just couldn't swing the $$$$ to bring you up to tune just my caar... But what day are you planning on coming to the shootout? I'm gonna really try for Thursday, Would you be interested in helping with a tune?
