Default [Tuning]: Did some more tonight.

Well, I decided to start from scratch tonight starting with the original 1987 Corvette w/manual transmission program. I ended up burning 3 new chips adding fuel in the upper RPM and pulling 2.5* out of the entire timing table. I want to drop my fuel pressure tomorrow and compensate with the chip. I only have about 1/2 turn I can go higher on the AFPR so I'd like more room for days where a few PSI more would help.

As you'll see my dieing O2 sensor problem is GONE across the whole board. She just wanted more fuel. I can't wait to get this thing on the wideband.


This is where I am as of tonight. Not too shabby so far. I'm totally new to all of this so I'm just taking it slow and making small changes each time. :)

So this diagnostic/tuning software is easy to use for a beginner?

Well.... that picture you see is a screenshot of EASE. I had used Diacom-Plus before, but EASE just plain rocks compared to Diacom. Its relatively easy to setup and monitor the car with. I haven't opened the manual yet, but just from playing with it since last night I've got a decent handle on how to see what i want to see.

EASE was $315. On top of that I use Tunercat to do the actual chip adjustments. That is I think $60 + $20 for your ECM definition file. Then there is the pocket programmer 2 that I think is $175 to do the actual burning.

Tough to say, but it *seems* as if it is moving through the 3000-5000 range faster.

Looks like you've got the fuel maxed out.

So can you fine tune the spark advance per rpm, to avoid all cases of knock retard?

I need to get ahold of these toys. At last, a computer nerd can put his skills towards something useful instead of home computers!

Unfortunately not, totally different. EASE actually goes from the ALDL to this small black box that is their "scan tool". Then from the black box to the back of your laptop's serial port.
