trying to hack away at 3500 file

[Weatheralls Auto]

tryin g to hack away at a 3500 04 malibu file, I think I have found the VE table, but not sure.

This look like it might be the VE?

140kpa is like 6 PSI of boost if i'm not mistaken....

i think you have 2 or more tables combined, look how the VE% drops off between 80 and 90, and below that the numbers seem all on the high side.

I inserted the numbers into a table, I think 140kpa is standard ve table for OBD2?
Ya, but I am not sure on the numbers, they just dont look right.
As a compare, here is a stock 04 3400 Ve table

an most def the numbers are way off, specially in the 90 to 100 kpa range.

I will keep at it every once in a while lol.
Hoping to learn to add vehicles to Tiny Tuner db, that and find where the DTCs are!

With some help I am making some headway.

looks much better?

I think someone has already done this because I have 3500 VE and MAF tables already.

And yes the 3500 VE goes up to 140kPa

And yes that is the VE that you have posted.

They hacked the file and made it have a 3.8L OSID and most of the tables match up, so if you need something from it I can export it from DHP or Tiny Tuner.

I am more learning how to Add new Tables Maps and Osids etc

I now have (I believe) the whole and correct Map and tables for the 04 Mali 3500 and is now included in my Tiny Tuners DB along with disabling DTCs.

I believe we should see a goody for DHP to also allow us to add osids/cals and New vehicles

Things ARE looking GOOD!

GM code engineers, WTF?

[Superdave]

boost them all!

[robertisaar]

boost them all!

while i have NO issues with that ideology, are there any 1.5BAR MAP sensors out there? if so, the PCM would still need to know it and then scale everything accordingly.

if there aren't and there is only 1,2 and higher, WTF is the point of going up to ~1.5BAR? the 1BAR can't read it and a 2BAR should read to ~210kPa... so why 140?

was the LSD making rounds that day? or did someone not scale the VE tables correctly when they hacked through it? if you had a testbench, it would be easy enough to determine, but i find it more likely that the 4 extra entries in that table are actually 25,35,45,55 kPa. above 100 just doesn't make sense in a program that can only see up to 100...

I agree...

I'd think that the 25,35,45 and 55 would be there to increase the VE resolution, $A1 is like that...

[robertisaar]

more or less, exactly what i was thinking...

Can you post the findings here, link not working.

I have been following (sort of) this thread with interest and wouild like to ask about ltft tables. Any info you can share?
