I got to play with the '98 Updated version at MTI this weekend, and looked all over the program. This setup is sweet! You can control almost too many things and it can be very confusing if you do not understand what each item does. The first tune we did, I tried changing all types of stuff and deleting a ton of SES codes. It made my car run like crap! hahaha, kept wanting to stall, had no throttle response, and only 20.5 degrees max timing. Ooops! Oh well, I know what NOT to do now <img src="gr_grin.gif" border="0"> . So, redid the programming with some subtle changes

-raised my max timing from 4K-8K rpm up to 30 degrees
-adjusted my injector sizes for my '01 injectors
-deleted P0300 random misfire SES
-4.10 gear ratio
-Adjusted Knock Retard attack to 50% of stock
-set mph limiter to 200

By doing these subtle changes, I was able to get rid of my MAF-T and HPP3 setup that I've been using for 3 years. The car felt great enough to go for some test-drives with the guy that was there to look at my motor, and he bought it on the spot! So, needless to say, I didn't have to dyno-tune the motor or anything since it is SOLD.

I can't wait to get my own '98 EDIT program, the best part about it for us '98 owners is that it only takes a minute to upload any changes into your PCM. You could do this in the staging lanes!

HPP3 takes 30+ minutes to program in my car! Yuck.

Oh I cant Wait, <img src="gr_grin.gif" border="0"> This is the biggest reson I hate the HPP3.

 

Tony...how does the gear ratio settings work...can you set it to anything whacky....like say...4.71s <img src="graemlins/gr_judge.gif" border="0" alt="[judgement]" /> or is there only a predetermined list?

 

Yes, you can do any gear ratio > 1, and you can go wacky with the tire size too. I'm working with an LT1 powered porsche where we're going to set the rear gear to 1.0, and tire size to 43", to get the VSS to read right. <img src="gr_images/icons/wink.gif" border="0"> You can do 3.90's, 4.89's, 5.25's, or whatever gear you can get.

And Tony, your tire size bug happened for me too.

Wow, where are all those posts Tony made which implied tuning wasn't worthwhile? <img src="gr_tounge.gif" border="0">

 

Jim, can you argue my results with a weak HPP3 and MAF-T? Definitely not custom tuning, and I could change it whenever I needed to. The LS1-EDIT gets rid of all the bandaid mods and allows US to change stuff when we want to. Best of both worlds. I still don't recommend mail-order fuel/timing tuning to any of my friends <img src="gr_grin.gif" border="0">

Congrat's, and have fun! You might want to sell your MAFT and Hypertech and pick up the personal version - that way you can make changes whenver you want <img src="gr_stretch.gif" border="0">

And sounds like you found the #1 temptation - making a ton of changes at once. It seems like a good idea at the time, but generally you get better results making one small change, quantifying the results, then evaluating that change and heading on.

Not arguing with you at all! Just razzin' ya Tony <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" /> If I had the cash I'd buy it and a spare PCM. This mail order stuff is frustrating.

 

If owning a MAFT I would suggest leaving it installed rather then selling it and using it to do fine tunes when at the track.
You'd be dialing in maybe +/- 2% and that would not have an ill effect on the calibration that has been done within the PCM

As you know it can be cold at the track in the AM but by noon much hotter and the MAFT will be a quick adjuster.

 

That MAF-T was the Devil! <img src="graemlins/gr_devil.gif" border="0" alt="[devil]" />

My car was very sensitive to changes with that MAF-T and it actually stung me in the *** when I tried doing changes with it at the track. Not enough time to learn the new change, and 9 out of 10 times I'd run slower by messing with it at the track. I'd rather make changes with my laptop on EDIT and reprogram the PCM. It only takes a minute or less, and I have my laptop there anyways to use AutoTap.

Tony, can u get LS1 edit for personal use yet?

 

I have the '98 version (PCM locked) <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

 

Sounds great, it's been a long time coming.
