Default How do Fuel Cells corespond to the Injector Flow Table

I've been looking at my fuel trim cells 6-14. Fuel cell 6 would be neg. but cell 7 would be positive.

I'm currently trying to get my 30 SVO injectors tuned in. So I've been adjusting my injector flow rate table.

Do I have to keep adjusting the table to get all cells neg? If I keep adjusting will some cells have larger neg numbers?

Thanks for the help.

The 30# SVO's large swing in LTerms is not corrected in the Injector Flow Table, it needs to be corrected in the Injector Offset Table.

It is best to maintain the same trend in the injector flow table. If you start to make it look like a noodle you can cause surging.

Good Luck,
Kevin

Kevin, I installed the injector offset table you sent me. I'm currently running my injector flow table at 135 % for my SVO 30 lb injectors. While crusing around I've been watching my ltrims for the different fuel cells. For example cell 6 my ltrims are -1.6 but cells 7 would be 2.3.

I'm not clear if I should move my table back to say 134 % or leave it. At WOT my ltrims are 0 and I'm not getting knock retard. I just don't want to run to lean.

Thanks

Hey Chris,

I looked at your a-tap data. Honestly, it looks very good. I also looked at your edit file. Everything looks normal EXCEPT your timing table. Your timing table is very very strange.

You arn't running lean. I looked at your LTerm data and the LTerms almost 90% of the time hover around zero. Yes, they are slightly positive (~2%) at times, but this is nothing to be concerned about. If you are concerned, shift your LTerms down a little bit. It isn't going to effect the drivability of the car, it is just going to shift your LTerms. Your tune looks good with the exception of your timing table.

I wrote an email last night, I will try and zip it out this morning.
