I have a '99 GSX with an '03 USDM Evo8 ECU running EcuFlash. The car is running well with the Rom I have now, but I'm upgrading from the stock 450 injectors to some 770's.

Below are the injector latency compensation values I'm using now with my 450's. What values should I use for my new 770's?

9.375 3.312
10.5469 1.68
11.7188 1.032
12.8906 0.672
14.0625 0.432
15.2344 0.264
16.4062 0.144

Thanks in advance.

 

Do a search on here real quick for a post made by Bez Bashni that deals with different injector scalings and sizes. The info in there should get you pretty close to where you need to be to fine tune the latency.
