Modifying custom tune for bigger injectors

[Garry]

Another guy in our club asked me if I could check out his 98 F-Body. He got a custom tune by Thunder Racing, but was wondering about the motor burning too much fuel. I just received another msg from him where he checked the data sheet that he had sent TR, and (either by error or because they were still stock then) the sheet lists stock injectors, where he now has 37lb injectors.

The results for me sound logical - to deliver the necessary fuel amount with small injectors requires a longer impulse than with the bigger ones, so now the motor is probably close to be drowned with fuel.

Where do I go in the tables to adjust for the new injectors?

Then use the injector flow spreadsheet to calculate the new data and put that new data into the B4001 table.

And that's all I need to do? Sounds easy ...

It's so easy even I can do it.

you need to know your fuel pressure.
