Hello community,
we have tuned Procharged hemi with 80lb Siemens Deka injectors and it runs good starting form 1100-1200 RPM, but it's very rich at idle.
The AFR gauge shows 11.5 when it starts and 10.4 when warmed up.
The setup is:
- Procherger blower
- Siemens Deka 80 injectors
- DW400 fuel pump
- fuel pressure regulator
Appretiate for any help.
see log and tune attached:
cant look at the tune or log right now but... have you checked your cold start enrichment?? and also if your getting high fuel trims the injector data may need to be tweeked in those areas?? Just a thought without looking at the data.
Your Inj PW Offset table looks stock. Here is what I use.
5 - 3.912
6 - 2.616
8 - 2.144
10 - 1.264
11 - 1.104
12 - .952
13 - .808
14 - .704
15 - .600
Add Cylinder 1 Fuel Mass to you logs. That will help with the adjusting the injector data.
