What would cause the coolant advance to go -680 and then a few frames latter add almost as much

(The reason why efi connections harness works is because they include the low speed gmlan circuit, and it only goes to the bcm in an off board function. Goes...

Siemens Deka FI114992 Do not flow 80lbs at 58 psi most injectors are rated at 43.5 psi, 300 kpa. At 58 psi it"ll be more like 92lbs

The first thing I noticed is your short pulse limit should be higher then you have it. Your short pulse adder table wont work with those settings.

I've been using the Siemens deka 80lb injectors for quite some time now. I even drove from Minnesota to Florida with them no complaints other then it was hard to get the data for them. what kind of...

Would I be right in guessing that your running 58 psi fuel pressure? I sent you a pm a few days ago. The injectors are rated 80 lbs at 43.5 psi and at 58 psi it should be about 92.38lbs that'll get...

Yes your right it should be 0.019 I missed that. I decided to set the short pulse limit at 1.9 ms because the injectors minimum Linear pulse with is 1.9 ms so that's where the short pulse adder is...

It took me a couple of days to figure it out. I was actually at work when it hit me :doh: haha

[QUOTE=dmaxs10;516586]Should the min inj pulsewidth and default pulsewidth be .599 I stead of .5927?[/QUOTE
Yes but if you set it at .599 it'll change it slightly at least in my case. For the min...

Here's the injector data that I'm using if you have any questions let me know.

Attached is the excel file for Fl114992 I used all set at 43.5 psi When I get time sometime today I'll put all of it in excel. It looks like your short pulse adder is pretty close to what I have mine...

What injector data did you use? If you post your tune I can look at it. By the way I calculated the injector data from the 2 data sheets I posted and so far I'm not have any of the issues that I had...

Here's a few others I came across

Is this the excel file your talking about?

You have to use your stock tune file if you still have it and do a write entire.

I noticed that too.
The way I understand it is if the injector offset data is correct. if your ve right and if you change the ve say 10% your afr would also show a 10% change I hope that makes...

I wish I knew what the right data was but Vernon recommend using the data off of http://sloppymechanics.com/tune-cabinet/ that Matt uses

My current setup is a 2003 p59 4.8l 4l80e Drive by cable 2bar RTT With 58 psi 1:1 pressure regulator.
Yesterday when I talked to Vernon at VS Racing he told me that the injector offset data is not...

I've never posted on here before but I can tell you that the injector offset data is not right.
I used the same data....
