I'm getting closer to start burning my own chips. I've done some reading in different forums and such, done my research on the hardware and software needed, but I really don't have too much of a clue as to how to analyze the data obtained from WinALDL and then make the needed changes.

Granted, I need to start off slow. But, could someone talk a look at the data I obtained today and see what it actually going on inside the motor?

I did a 15 minute run coming home this evening and I saved and formatted the BLM Table, O2 Table and the SENSOR LOG.

All feedback would be greatly appreciated!!!!! :hail: :hail:

Oh yeah, mods are in my sig.

Thanks,
Mike


Hum... I tried to attached the .ZIP file but the message board won't let me, so here's a link to the file.

If this doesn't work, please tell me. Thanks again!

 

That log doesn't look like its worth much. I could be wrong but I didn't see any areas where you held a constant speed for longer than 30 seconds.

You want the BLM and INT to stabilize at each RPM/MAP point. If you are moving the throttle the Acceleration Enrichment will affect the BLM/INT reading.

This means driving the car very steady at each RPM point in the main fuel table for a minute or more in the highest possible gear.
Obviously 3200RPM in OD or 5th gear is gonna get you a government notice of confiscation of funds or worse so....

 

Hum... ok. Thanks for the input. I was in some traffic. I'll try another pull and try to get some better data.

 

traffic = skew'd data.

Get out on a open road and cruise steady for a while...if your shooting for good BLM data.

 

Still looks good to me. Take the car to the 1/4 mile or a dyno if you're serious. Play with fuel pressure but it looks like you could use some fuel table tuning. Might just be AE but it never hurts to tinker and data aq. Does the car fee fine and have you take it to the track yet?

 

As far as taking it to the track, I'll have to wait until it gets warmer up here (New England). This past summer I did get a reading from a G-Tech unit.... 15.79 @ 89 mph (But that was before I installed the cat-back system and the HI-6 box.

Yeah, she seems to run fine, a little soft on the bottom end but I'd like to begin tuning because I plan on getting headers very, very shortly and then an intake and heads later this year so I know that chip burning will be a MUST!

From what I "think" I understand from the data I captured, it seems like it's rich on the lower end and lean on the upper end. I've read somewhere on here that bigger cams will do that with a stock chip installed. Am I correct on this? If so, what would I actually make adjustments to?

I have the timing at 6* BTDC and that's about as far as I can go without getting ping. If I go 8*, it'll ping under light loads (and yes, I can hear it) so I can't go any further than 6* (this is while running 93 octane).

Thanks for the replies guys, I'm new to the electronic stuff (I come fromt he old school of points/condenser and carb tuning). Any other input would be greatly appreciated!

Later,
Mike

ps: In the next couple of days, I'll try to get some better data logged and I'll post it.
