Tuning a 93 3.4 Firebird

[robertisaar]

the ECU interpolates a weighted value based on the VE tables RPM and MAP. spark is the same way.

so if it's at 1175 RPM and 49.5kPa, the value will be VERY close to the 1200 and 50kPa cell value, but it will be modified by the 800 and 45kPa cell.

new chip has been burned!! with changes to the VE tables....

question: The graph i was working on had VE cells for Map kpa @ 600 rpm, 1200 rpm, 1600 rpm etc.

but what about all the rpms inbetween? For instance my car usually idles around 1,000 so will it idle any better now that we've made the changes?

There is probably an easy answer to this question but since i'm a noob i'm going to not feel bad asking this hahha

[tkoforpresident]

just so you guys can keep tabs on what i'm doing with the tune (more behind the scenes now than before)

Robert has shown me how to work on my VE tables with a cool fueltrim program so before i datalog again i'll be doing the little changes available to the .bin and then burning the chip again. (Rewritable chips FTMFW!!)

i thought the whole point of a vacation was to get AWAY from everything....

Well, internal combustions engines is kinda like one of my children -- no one gets left behind

As long as the car is in the "off" position, you shouldn't have anything to worry about. I have actually messed up and burned chips with the pins in the wron position (my burner will burn 32 pin EEPROM's) and never had a problem - except the car ran very irregular lol.

Biggest thing you have to watch out for is putting the chip in backwards.

John, what do you think of my datalog?

and don't worry, i will not make that mistake with the chip. It wouldn't be the end of the world considering i have an extra one on hand....

p.s. just pulled the chip and nothing seemed to smolder/light on fire, so we are probably OK!

i never disconnect the battery and have yet to fry one chip...

[tkoforpresident]

Robert, i'm going to stop over at my friends house and retrieve my chip with the tune on it (since i lost all my files). Then maybe we can finish the automated VE simulator you've been helping me with.

Then i can change it on the tune, burn the new chip etc.

Question: do i need to disconnect the battery before removing the chip from the computer or should it be ok?

thanks

[tkoforpresident]

lol thanks Bob, i appreciate the kind thoughts.

this final log is a bunch of failed start up attempts between the first and third log. don't know if it will help....

[tkoforpresident]

this is technically the first log. it was the initial start up until reaching operating temps at about 180*
