Someone care to share injector table, have a RICH WOT issue
Im having some issues with tuning my 2000 FRC.
When I bought the car I tossed a 228/228 116lsa cam in it and a LS6 intake. When I pulled the tune I noticed someone has messed with it since it had 28* timing WOT.
I ended up leaving the tune and the car ran great, just a bit fat 12.5ish WOT, ran the entire last season this way and made some 12.4 passes as is.
Well over the winter I swapped on a set of Patriot LS6 heads (64cc), kooks 1 7/8 LT’s, custom 3inch X-pipe along with some 42# injectors (may be my issue)
So I start doing my tuning and I got my injector numbers from my friend who the injectors came from. Turned out I had to use his timing also to get the car to idle proper.
I start doing WOT Pulls and im getting like 10.9:1 AFR, so I pulled around 15% out of my MAF (from last year’s tune) and Im still running rich around 12.8---then ramps down to 11.9 at 5500rpm
Another issue is im getting knock at weird times, like rolling into the throttle or off a stop (pretty sure its false since the custom 3inch is tight as well as the headers.
Now I haven’t ruled out an exhaust leak, but that would cause my AEM W/B to read Lean. I do hear a slight tick when driving but Im unsure if that’s just the valvetrain noise added with the longtubes.
Does anyone care to share their Injector tables? (EFILIVE)
Just seems really strange that im pulling from my MAF when I should be adding. I think the upper 11,000hz I only have around 375 in the cell. I compaired it to a stock 02Z06 and the maf values are way higher.
I think my next step after figuring out the injector tables will be return my VE-MAF-TIMING to factory settings and start over.
Thanks

If you do a google search, somewhere (efi live forum maybe?) there is an excel sheet that will calculate the numbers based on pressure and rated flow.
