I received my injectors yesterday and got them installed. Flashed what I thought was going to be the correct injector data and started it up.

Motor runs 18 afr at idle (800 rpm) until fuel trims get to about 15% or so.
If I speed the motor up to about 1200 to 1400 rpm the injectors seem to run better and stop adding fuel, no negative trims but at least not adding fuel.

I have (2) sets of data for these injectors pulled from the internet.
One set from a post by Busta9876 and another set from a HPT repository file on a Whippled 6.0. Neither set worked very well.

Researching late last night I found where some folks are just running the stock injector data and changing the flow rate. I currently have it flashed with stock injector data, and a 41.67 flow rate.

I did not get to adjust the tune to much last night. I don't think the neighbors appreciate the sound of the engine as much as I do.

Hoping to work on it this afternoon.

Where should I start with the tuning?
I think I need to get it closer to Stoich before trying to re-tune MAF and VE.
And I don't want to retune these items if I need to adjust injector parameters first.

 

That's the problem with these injectors. There's no official data. Set the IFR to 43.8 and tune the VE accordingly. They will work like stock.
