Hi, im quite new to this and have a question.
Im about to change from my stock injectors(242.4g/m(n-heptar)) to new injectors(334.5g/m(n-heptar)
Its for a Volvo 940 -95 LPT with ECU 962.
In the definition file a find a constant called "Injector constant" set to 128
And the conversion is:
Equation format X128
Argument 0
This items raw data
So, anyone got any mathematical formula for changing the constant from 128(0-255) to what i need?
Bigger injectors

Also if i change to those injectors plus a 3" AMM(air mass meter), does that affect it in any way? Or do i need some other modifications to achieve a good AFR?
Because according to my own logic(which probably is screwed up) says that 3" AMM and those injectors would add up, and i can still go for 128 constant value...
Please correct me if im wrong, and thanks for the quick reply!

anything MAF related is something that i shouldn't be asked about.... i don't like them or know too much about them.
as for getting that number: i just took the existing injector size, and the new injectors size, and found that they were about 38% larger...
tip: change one thing at a time. don't change injectors and the MAF at the same time or else you'll run into a world of trouble... swap injectors, change the constant, datalog, get it running good, then swap the MAF (AMM, whatever it gets refered to on a Volvo.

Okay! I send many thanks to you for helping me halfway in this concern!robertisaar wrote:anything MAF related is something that i shouldn't be asked about.... i don't like them or know too much about them.
