I'm adding a set of 0280155868 injectors from FIC to my 2001 Camaro for the Thompson 383. I previously tuned the car on the stock 28lb injectors, so this is my first time upgrading to 42lbs....which parameters do i need to change so that i dont mess anything up?...FIC sent the data download so i have a file with universal data and plug/play GM data, but im not sure what to enter into my tune.

The plug and play GM data because it's a GM. Just copy what they give and what matches your tables, pretty simple. You're only going to change the 4 main things they give you, flow rate, offset stuff, min injector pulse, short pulse adder.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
flow rate provided on the FIC chart is Flow rate vs g/s......but in HP Tuners the parameter is Flow rate vs kpa....is there a conversion?
HPT is so popular that most qualified injector manufactures/distributors will supply the correct data to paste directly into HPT config. files. I also assume they point you in that direction when you look at the file FIC sent you.
In the top upper right corner of that table it allows you to change the units, just click the lb/hr and it will cycle through to g/s.

the file is 380-6868 ......it would be much easier but it doesnt look like i can copy and paste to HPT
thank you!!Originally Posted by 5FDP
Or you can right click anywhere in the table and go to 'Units'.

Funny how accounts marked as 'banned' are still able to log in and do stuff on the site, huh?
ok, got it all changed over except on the FIC chart there is an entire line of values for "short pulse correction" but on HPT there is only a single box labeled "short pulse limit" with a single number of 3.997 ms........does this need to be changed?

Found on another thread the min injector pulse for 0280155868 is 0.386….FIC did not include this info
Here. Transient tab also.
