Well I got a chance to load the tune and go test and catalog it. Wow what a difference. How my tune was I was defending pulling a ton of fuel. I really appreciate the help. I haven’t updated my sig...

I just need it to fuel to the wot shift point. I believe it’s at 3250

Hey everyone. i have a tune i have been working on for a while. it runs great but at wot its hitting some sort of limiter i am not finding. can someone look at the tune and log?

I figured there was more than just taking a percentage out of the main injection table. But I didn

This may have been covered already but I haven’t found it or seen an answer to my question. I have a set of 100% injectors that I’m not completely sure how much duration I need to pull to get a...

Did you end up figuring anything out on the truck?

I would like the list of fueling statuses if you wouldn’t mind sending them to me

This is interesting

I finally got mine to stop defueling I believe the limiter I was hitting ended up being the boost fuel limiter.

Mainly in the lower load areas. Basically same as your problem.how much was your varying?

I was curious if you had gotten this problem fixed. My truck does this also. How much is your actual over and under shooting the desired?

Any chance of a class being held in the mid south? Oklahoma or texas area?

I seem to remember seeing on here someone saying what limiter 52 would be but I can't seem to find the thread. If anyone can point me in the right direction I'd greatly appreciate it.

Today I finally figured out how to link the scan and tune tool to watch a datalog. Just wanted to say thanks. It's making tuning a million times easier and more precise.

I believe I have seen a place in the program for high idle. The weather here just became cold enough that my truck will high idle in the morning without any changes in efilive.

Oh ok thanks. :doh2:

I haven't done it with the tune opened. Ill have to try that.

I know that normal running condition while accelerating is "7".

I was confused at first as well. Still am sometimes. But I would datalog and also just display to see what duration my engine was actually doing. Then you can go back and find those areas on the...

My truck is now reading 15 at wot. It's a very slight defuel now. But could anyone tell me what 15 would be?

I wanted to post an update. I increased a section in my fuel boost limiter and also in the fuel pressure limiter in the middle section of the map and I have almost completely gotten rid of the...

I adjusted that table a while back and it didn't seem to make any difference on my truck.

thanks for the help garrettg.bpd. ill log some more tomorrow with the changes you made.

Would I be able to fix that in efi live or is that a sign of a weak fuel system?

ok ill look into the torque limiter. thanks
