OBDI 427 tune
I'm going to a 427 from my current 350 set up. I wanted to know if anyone had a Bin file they would share for a 427 with 42# injectors. I'm using an 8D XDF. My thought was that I could have this as a starting spot and then go from there with adjustments. I know everyone's combo may be different but it would give me a starting point.
Or should I bite the bullet and go with a new computer. If so is the Holley HP the unit everyone goes with? I see they make a kit, #550-601N, that looks like it works with a TPI. If I am correct I've read that the only thing that doesn't continue to work after installing one is the instant and avg. miles per gallons read out.
Thanks
Chuck

[QUOTE=95wht6spd;1601753908]Also Haltec, Motec, etc. If going that far, I think I would convert to a big inch LS.

Thanks 84, If you want to that would be great. I have tunerpro etc. and have done all the tuning for my current set up. I could just adjust for the larger injectors and see how it looks. I am just thinking if anyone has already done a 427 it might shorten the trip.

When I did mine I built it off one of the bins that came with the ebl and I more or less just scaled the VE tables and put really conservative timing in it. If you're using a similar rpm band and induction setup you may be able to get away with scaling the injectors and adding fuel to the tables and work from there. I started tuning mine back in February and I am now at a point where the thing drives better than stock but it took a lot of data logs. The VE learns did help a ton though. I'd still be working it if I couldn't do that with the wide band.
Like i said, no promises on what I would build but it would run and be safe. I would check third gen too and see because someone there may have something.

May not be a bad idea to check third gen either. Their tuning section is pretty beefy and someone may have so.ething that'll be a good starting point.

Is yours a 427? If so then that would be great if you would share. I was thinking of doing the same thing with mine, calculating what I thought I needed to do to change VE to adjust, lower the timing and go from there. I've got an LM1 and a wideband I can connect thru Tunerpro. I'll also check with Third Gen.
There may be a 435 bin that came with ebl i can look at to make some guesses though.
