According to my MPScan program, I'm running 2.0.2.9. Not sure why it's showing such an old version, my MPScan is up to date

something is not right. what is the creation date of the log file you posted?

[DoubleD]

Shows 6/5/2014. That does not seem right.

[wowzer]

in mpscan if you go into the menu help/computer info, it will show you the user directory where the log files should be saved in. look there for all log files.

[DoubleD]

Here you go, date is 8/8/15

Took the car on a 700 mile road trip to Jackson's on Saturday, car ran well there and back. Averaged 25-26 mpg on the trip. I did notice that when I just roll into the throttle at say 1/4, As it starts to build boost, it will run pig rich 10-10.5 and below. I am going to try pulling fuel out of the part throttle lo Map table and see if that helps, If this fixes it, I know why I have such poor fuel economy driving around town. Also partook in a couple of races, need to pull more timing at 3800-4000 and then start advancing the timing after that. Leaving plenty on the table there.

Just as an FYI, the staging limiter and switch able boost are still not functioning and I would really love to get them working too.

[ShelGame]

The problem with switchable boost and the staging limiter is only the switch itself. My code doesn't read the switch states correctly and I don't understand why.

[DoubleD]

Just an FYI for you, I have tried the staging limiter without a switch and it is still not working

[DoubleD]

I was looking at the part throttle Hi map table for my car and I was comparing it to my friends table. Mine is based off of the SBEC2 (93 IROC R/T) stock cal and his is the SBEC1 (91 Spirit R/T) cal. Why do the tables look totally different? These are the same motors and very similar ECU's, shouldn't the stock calibrations be the same? I will post pics up tonight of what I am seeing.

[ShelGame]

Stock cals should be exactly the same.

There are experimental .asm files here - https://drive.google.com/drive/folde...F9nRWl0WEM1Uk0 (files ending in x.zip). Compile with the appropriate file and see if the switchable boost or staging limiter works...

[DoubleD]

None of the files in that link end in x.zip

[ShelGame]

Check again later. Google Drive still isn't as good as DropBox. Takes forever to get files in sync...

[DoubleD]

Could you email the .asm file to me? brmeyers@mtu.edu
I have no idea why it has not showed up in the link yet.

I am getting close to switching out my injectors and stepping up to the 120. I went thru last night and re-did the fuel tables and ignition timing. I am going to re-do my tune with these values. I would like to know if it would be more helpful for other if I set my base fuel pressure at 55 psi, like stock or set it to 45 psi. I have an adjustable regulator so I can set it wherever. This would be with 75 lb/hr injectors on premium fuel.

[ShelGame]

I always think you should set your fuel pressure to what the injectors are designed to use. That really means that injectors that don't come from Mopar (IE< +20's or +40's) should be run at 43.5psi.

For some reason, Drive is syncing all of my files on my little laptop. And, of course, it stops syncing anytime the screen turns off.
