staged injection settings
I am having a huge spike in fuel when my staged injection turns on. I have my car pretty well tuned. It drives great and has good power, but when my staged inj. turns on my afr's drop to between 9 and 10.5 for a plit second and then they return to a normal range. I have tried to adjust the settings for a smooth transition. I have raised the rpm from about 3500 to 3800 and the the transition ign events from 70 to 250, and taken my primary reduction delay to 0.
Am I missing something or have I shot myself in the foot with my settings. I have stock primary inj. and 720cc secondaries. Thanks for all your help. With out this forum I would still not have a running car. |
Sounds like you have an MS1?
Do you have your scaling factor set correctly to your injector sizes? |
I'm running ms2 w/3.0 board. Yes my injectors are entered correctly. I didn't notice the drop in afr until I got my tune closer to ideal. I am running low z secondaries with 10 ohm resisters. could that be my issue?
|
What's your firmware level? I think the new firmware on the MS2 supports duty based staging which may help you. Honestly I'm a bit out of touch with the MS2 firmware as I don't have one handy...
|
We support duty-based staging and table-based staging in the latest firmware revisions. I would recommend using table-based.

I think I am running 3.1.0. time to upgrade firmware again.
|
I believe 3.1.0 already has table-based. I'll have to double check.

figured out how to use the table. I'll play with it and see if I can fix my issue. Does anyone who is using the table want to send me their settings as something to go off of?
|
does anyone want to share their table based staging settings?

That's more or less similar to my NA staging settings.
