No, I do not have shaft speed to log.
The converter will not stay locked in anything other than extremely lite load, such as flat or down hill. I am assuming rpm rate of change or something similar...

3200 stall, brand new converter. The trans was not built locally and there have been suggestions that the tune file may be the culprit. I was hopping that someone here may have enough experience on...

I have a fresh rebuild of engine and trans combo in a C5 vette, so for the most part untested. Now 383 LS1, cent. blower, rebuilt trans with 3200 stall. On first test drive just to verify all works...

At this point it doesn't really matter if the converter is as loose as you think it is or not, I assume it's a street car that you do not want it to idle at 1600 rpm. You need to find where the air...

This is how I do it.

I have a MPVI2 and have not studied the MPVI3. I think if you look into the MPVI3 it is simple to do it with the hardware you...

Open your stock file, then modified file as a comparison. Then select the tab "compare", select view comparison log to see what was changed. I don't know the specs for the cam you mentioned but...

Thank you for your time.

Are you putting the decimal in the wrong place for your gear ratio? In your post you have 37.3 and actual should be 3.73.

Well I just tried to goof it up as bad as I thought you may have but, it...

I see now, it clicked when I viewed the pics you attached. My understanding now: Power enrich can happen at any RPM or MAP under the Boost enrich threshold and therefore, Power enrich should match...

Those are the kinds of things I appreciate you lending your time to review these files. I'm sure I was looking at the PE and Boost enrich as two separate scenarios and didn't think about the overlap...

I'm fairly new at modifying the factory tune files using HP tuner software. I would greatly appreciate if you guys would look over and scrutinize my tune file I'm about to write entire to my c5...

Fuel psi under load? Flow test on fuel system? Injector duty cycle? Excessive air leak before or near o2 sensors? Mechanical issues with engine, broken valve spring or the like.

Do you know how to use the HPT software? If so, post the tune file and a log of the start up for us to look over. If you do not know how to use the software, learn that part first. Should be able...

Yes. You will have to take the epa test to get the code to unlock the greyed out areas.

Google how to save a screen shot. Select the add image tab in this thread. Select the image you previously saved to your computer and add it to your post.

Are you saving the log file and then reopening it?

The water/meth could change the AFR by a full point or more depending on how much your engine was ingesting when tuned with it functioning properly. Is it functioning properly now? Do you remember...

See if the tune you need is in here:

You will need your account number.

OS = operating system, in this case.

I think there is a link in the stickey's to abbreviations and acronyms related to HP Tuner/automotive general knowledge.

Cam, crank sensor? Short of that it does sound like a valve control issue after all that has been mentioned. How about put a timing light on it and see if the timing light does anything weird when...

It's much easier today than it was 25 years ago, if you don't understand it, Google it! You won't learn it in a few hours, it's gonna take hundreds of hours to get proficient. Start by plugging...

Is this a new problem or something you have been dealing with since the original tune?
Idle spark looks excessive also, no torque reserve.

Easy to eliminate possible exhaust issue, unbolt it and give a go!

Are you sure this is the tune file you used for this log? As you noticed the desired rpm and actual rpm don't match, yet the ECM is pulling the timing down to almost zero. I'm new at this also and...

I now understand how to use the HPT wizard but that's not my point. The point is, with the HPT default when reading the stock file is 3.42:1, do I assume the shift scaling is correct for the actual...
