Issues with using TunerPro on a 94 Vette with 155k miles

[Danspeed1]

your 1990 is a completely different beast than this guy is dealing with

Interesting... not that it matters at this point... you know the history of that car, but I wonder what the issues were. I hope he is able to find a solution to his problem as I am sure I will be tuning an lt1 corvette sometime in the future.

Good luck Ken...

Didn't mean to ghost my own thread lol, was expecting a popup to appear in email when I got a response. Though I may have to check the email I've got on my accout...
I didn't know that the LT1 in timing for talking to the ECM, that's odd that they'd be set up like that. I'm using $EE-16188051-Y-body-V3.8.adx as my TunerPro adx file - how much different is $EE hack from TunerPro? I'm assuming it will work the the same OBD cable I've been using, but does it require something specific be installed to have $EE hack talk to the cable?

tunerpro acquires data and tunes bins for pretty much any ecm. i wrote eehack so you could do a bit of real-time 'parameter testing' such as tweaking timing/fuel/idle on the fly. it is written just for the lt1 and has a ton of lt1 specific stuff. i put tons of crazy features into it -- it does pretty much everything that you can do with the lt1 datastream. you need to use tunerpro for editing your bin, though.

all dataloggers you'll run into for windows are just serial stuff and will work with your cable

...of course it's free so you could just try it and see how that works for you, instead of reading about it

Tried out $EEHack and it worked on the first try. Was able to view Int percentages, though not sure how these translate into real values - it gives positive and negative percentages, but what's the conversion to real world values? Ex. +2% or -5%?

[JimCT_9C1]

You can change display units between percentages and raw BLM / INT in $EEHack using the Settings panel accessed from the main control panel.
The conversion from raw to percentage is % = (RAW/128 - 1 ) * 100

Hope this helps -

i set the default like that because i think viewing int/blm data as raw is completely useless for actual tuning, you have to do division to turn it into a multiplier or percentage anyway

if you have a question about anything in eehack try hovering the mouse over it, it'll give you some details

in this case it would explain the default display, and indicate that you could go to the settings to change that.
