86Chicken

First, let me say that I tried searching for the answer before I posted but could not find anything because I am not really sure what to search for.

On my 86 383 LPE Vette I found out (thanks to the forum) that I am running a 32 bin. For the longest time I have been fighting (unsuccessfully) with getting this thing to log at 8192bps - different SW, different HW, same cable tho (Steve Ruse, WOT Elec.). I read something about 86 code being a little finicky and figured I would try burning an ARAP 6E stock bin to the chip and now everything logs fine. I have not actually started the car yet - all of the logging was done with key on - engine off just to see if it works.

1) Will the engine run with the stock 6E ARAP? I know it is not optimized for this engine but nothing should break/blowup right?

2) Are there any reasons to not do this? Too complex for newbie, dumb idea, etc.

3) Can I just take the 6E values and massage them to match the LPE values for a starting point? Is it that simple?

Sorry for the newbie questions but we all have to start somewhere.

Thanks for the help!

The ARAP is a vette bin. So the car should at least run on it. I don't know if the speedo will be right thou.

The ARAP 6E will only run on your '86 if you disabled VATS in the ARAP. Changing the fan N/O flag is also required for proper fan operation.

What is the best way to disable VATS? Could not find line in my editor, using GMPCM. Did find VATS values.

I guess, you need a better editor.

ouch, I also have tuner cat, rt tuner, winbin, promgrammer. I was using gmpcm because every new ecm tdf file is another $20.00 & i have unlimited pcm files with gmpcm.

Sorry for the delay but I am back with an update. The car runs with the stock ARAP just as crummy as the LPE chip did. I did a few datalaogs w/ TunerPro and the BLMs are all over the place. They went from 80ish in some places to the high 100s in others. Looks like I have my work cut out for me.

The stock timing map was also much higher than the LPE version which explains the couple of knock counts I saw.

The car also still has a major idle overrun problem. Everytime I push in the clutch it wants to stay at 1200 for 15-20 sec. then drop to 850 or so. Any ideas? I have not searched the archives for this problem yet.

Thanks for the help! With the the way this 6E setup looks I may be back to ask a few more questions soon.

Thanks
Dale

BTW: TunerPro can handle VATS and is free - May want to take a look at it.

86 -

You may want to start with APYP, since you seem to have a manual tranny (you mention a clutch). APYP is the manual 'vette version of the ARAP. You're correct about the spark tables being hot on (both) these bins. You may want to take some advance out of them.

Just doing the switch to APYP should clear up some of your idle/follower/surge issues related to your transmission.

APYP should already be in your bins folder in TunerPro. It gets installed with the software (I'm a fellow $6E guy).

Cool - I'll give APYP a shot.

I managed to get ARAP relatively close on fuel by setting the injector constant to 23 - hopefully the same trick works as well on APYP.

I have a TunerPro RT question: Is there a way to export the ALDL logs to some kind of comma separated values or similar for use in Excel? My datalog trips usually wind up being around 10K samples and I need to do some sorting to find what I am looking for.

Thanks again for all the help!

Hi Dale -

I was supposed to get the comma/tab delimited export feature into 3.07, but it didn't make it. =(

It will definately be in 4.0.
