VEPHD Overflow Error

So I was working with VEPhd to get it set up for my own use. I created a spreadsheet to paste the 2 tables from my Tunerpro into(using extended Super AUJP code). I actually created a table to take the standard VE Upper table and interpolate it out to fill the extended one...but thats pretty straight forward.

Anyway...so I decided as I was playing that I was going to set the dat file for vephd to read the ENTIRE tunerpro Super AUJP datalog so I didn't have to 'think' to have it translate the datalog for VEPHD...There were 200+columns of code in that. Figured it wouldn't be a problem.

I did that and got an overflow error. Didn't catch it the first time as I'd never used the program...but thankfully I didn't run the car(although the corrections looked believable). So I took and decided maybe the 'overflow' was(For a mech engr like me not a EE) was simply...TOO MUCH DATA. I shaved it down to 12 columns and VOILA!

It went through, said it cranked 13604 rows of data(exactly what it should have) and output a VEPHDOUT.csv file. I think I'm off and running...just wanted to put this out for those that are messing with it as I didn't see much about overflow errors and VEPHD.

Is there a place I could go into the code and have it be able to handle that much data or am I better to just play with the datalogs(took an extra 5 minutes maybe). Or maybe there is a format I can save in tunerpro when it exports datalogs to keep it hte same every time(without me manually selecting it hte same way every time.

Any suggestions? If not, not a big deal...just thought I'd ask.

Re: VEPHD Overflow Error

Sounds like it's time for someone to jump into the QBasic code which VEPhD uses to digest the datastream .

Re: VEPHD Overflow Error

So it looks like for me as well(saw this referenced in other threads)...for the BLM 2nd column...I needed to put the same column in as the first or it halves the fuel required.

Re: VEPHD Overflow Error

One last comment unless others have comments. If you get errors spit out in your datastream(I got 10% errors in the last datarun a few minutes ago)...you need to 'clean' those out to get the PHD right. Lol...first one I tried to do I looked at the graph and one whole section was at almost 0 fueling. That was where the errors collected.
