I have not been resetting fuel trims :( I was under the impression that by setting them to disable they will not be learning...have I been wasting my time so far?

Jabbott I get what you are saying and I have been looking at a lot of posts and info trying to figure out the 50# but the few good tidbits of info I got was get my VE table good with my stock 28# and...

So I was sick of dealing with the 50# injectors so I put the old 28# (stock) back in and did some SD tune scanning. My first scan was way off so I copy/paste and drove some more and the VE table went...

Well I was hoping that the injector data was going to be the same as the stock (except the flow rate) as per FIC's web site. So yes other than changing flow rate I didn't touch anything. I will...

So now I have been driving around trying to get this VE table correct and I have done 10+ decent drives but the table will not get any better in some areas. I will log copy paste and log more and it...

So started scanning and my afr/VE table is all over the place. Also with the fuel pressure difference noted above should I up the injector size.

Russ thanks for all the help on this I feel like a total punk when it comes to this stuff. When you say enable temp to 140* I am confused as to where you are talking about

Is it the temp on the...

When you say disable fuel trims are you talking about in the OL/CL under fuel. I just looked at it and they both say disabled in SDtune. Also just changed AFR from % to (afr).

Well I took Russ' advice and looked in one of my books for VE tuning and I helped out a lot. I was mainly going with the tuning school but it did not mention messing with the VE tables. So far...

Man I had high hopes for this set up. Is that really all it is? Crappy injectors or am I missing something?

So I changed the injector size again for the higher fuel pressure and still runs like crap...I am scratching my head now.

Also the chart for the injectors for the flow rate of cc500 the pressure was 43.5lb. I have a fuel press gauge and I am at about 52lb in fuel rail. Do I need to add more to the Injector flow rate...

So I installed a new fuel rail with some 50# injectors. I got them from FIC and they said
"Tuning is a snap as it is the same injector that is programmed in the LS1 computer Set the new IFR and...

Hey, Stationed over in germany and just did my first scan a little bit ago. It has a mail order tune for the last few years. Car is an 02 Z28, ported MAF, LT's with TD's, and a 160* stat. Other than...
