Yeah, that's what I tried to use in the beginning. For me, getting it to idle and drive smooth was bad. I then called Deatschwerks about the data being different from what my remote tune had in it....
I've been working recently on getting the correct DW 95lb injector data for my car. The data supplied from my original remote tune had really bad drivability problems with a lot of surging.
I...
Did you happen to find what was causing this knock retard? I have a 2012 and am having the same issue with getting some knock retard on take off. If I take off normal I get none, but if I take off...
Is the knock starting right after Tip-in has occurred? I was getting knock and had to increase the Tip-in spark retard in some areas. You can view this by logging Spark Source.
Tried the newer strategy in my car and it is a no go. Runs fine but the cruise control buttons on my steering wheel do not work anymore. Looks like I am going to have to try a 2012 strategy.
I see under Engine>Airflow>Electronic Throttle that the Throttle Angle Min is 3 degrees. I have only seen .0625 degrees on the tunes I have looked at. Maybe that has something to do with it??
Have you had problems with cruise control after swapping strategies? I thought I've read that some have had those problems, but like you said, it may have been when using an older strategy in a newer...
I would appreciate it. Thanks!
Here is what I am using. I didn't use a dyno though, I did runs on the same stretch of road and used the Virtual Dyno software to graph out the results. This is on a 2012 GT with a Vortech. Also, I...
So my 2012 GT Manual has a strategy, FPDN18A, that has the bug that does not allow me to adjust some of the settings associated with Tip-In. Under Spark Tip-In, the two tables Pedal Enable and...
It may be closing the throttle to control engine torque output. When mine logged IPC Wheel Torque errors, it would reduce the throttle angle to bring the Engine Brake Torque down to the ETC Torque...
My 2012 goes bonkers when I change Engine>Spark>Advance>Spark Tip-In (Pedal Enable and Events). These two I can't touch.
I thought I read somewhere, in this forum or another, that the early Roush tunes had them turned off, but the later ones had them turned back on.
Also, not to hyjack this thread, but did you...
When I had a hunting idle, it was from my injector data, which then affected my MAF Transfer Function, which then affects calculated load values, etc. So I would look there.
Also, I have a 2012...
That's what I did. Set the OP table timing I want on the bottom row, and added 2-3 degrees to the row above it. I also set all spark adder tables to 0, and reduced the knock advance table to 1-2 for...
I have seen the same knock around 40-60% load as well with my setup and both values in the graph. What I've done is logged all enabled mapped points, as well as the usual load, spark, KR, etc. I also...
I hadn't looked at the other datasheets for the other sizes, but that's good to know. What I do know is their data for Coyotes is unusable. Injector Dynamics next time for sure!
Update.. Using the datasheet that came with my injectors, they flowed a static 957cc @ 3bar. Using their website calculator, that comes out to 91lbs/hr @ 3bar and 111lbs/hr @ 4bar.
I found a...
I just put in their data and adjusted my MAF and I'm getting the same bounce. Trying to hold 1500 RPM or just barely tapping the pedal gives me a bounce. I noticed in my datalog that at idle I am at...
Here is the reply I received from Deatschwerks:
Thank you for contacting us with your inquiry.
The way the Ford Calibration Data is formatted, it can be used - without changes - in either...
I have the Deatschwerks 95lb injectors in my 2012 Mustang GT as well. I put the tuning data that I am using, for a stock fuel system, in a spreadsheet for you. My car was originally remote tuned...
