383 tuning help

[Kitch]

I'm not sure what Ed at fast chips uses, did the piggy back chip he sent you look anything like the Moates G1 memory adaptor?

I use an APU1 and have been happy with it, I've used it with my 94 Chevy van and my 95 GMC Yukon.
I did buy a GP1 package so I could fit the programable chip to my PCM but if you don't need the quick change ZIF socket and a spare chip then you could just buy the G1 memory adaptor.
I also later bought the HDR1 memecal header only because with the APU1 it allows you to read the contents of the stock chip.

Kitch, myburb, So if I get the apu and a GP1 package I should be set to tune this then? Do I also need the ZIF ? What does that do for me? I want to order what I need to do this..
Here’s a pic of Ed’s piggy back adapter. 9D2DEA51-D0A3-4859-96F7-F95841CFF9BB.jpg

The prongs on the chips are very thin and I tended to get one bent trying to put it in. The zif allowes you to just drop the chip in and flip the lever and you are done. If you want to get the tune really good you will tweak and data log a LOTA LOTA times. The only problem with the zif is it makes the chip sit up higher. Moates does have a low profile zif. What some do is use the zif while you are tuning and when you get the tune done then you can carefully insert the chip without the zif and then the cover on the case will fit ok. That adapter you have looks like it does a similar job to the g1. With the g1 you retain your limp. Not sure if yours does.

I originally started with the low profile zif for the sake of the low profile and cover clearance, what I found was that I was R&R'ing the chip so much that the lesser quality and more difficult lever operation was causing some grief so I went with the higher profile / quality zif with the metal lever, sooooooo much better !
With the taller zif the chip guides into place very easy and the large lever is easy to lock even with my gigantic fingers.
I can reach down and remove the chip without leaving the captain's chair.

I will someday put the low profile one back in and the cover on but I still find I like the ease of pulling / installing the chip and still play with the tune even after getting it REALLY good. (I never leave thing's "well enough", got to have tinker-time)

1 year ago I didn't even know this tuning was possible, now I am comfortable with what I do. I will say that based on the steep learning curve I am glad I went simple and didn't go the APU1 route. For me, stopping and pulling the chip and re-burning a change is close enough to "on the fly real time tuning".

Thanks for that experience with the zif guys. Dktool so what did you use for doing the re-burning?? I was going with APU1 cause it looks like its all there to do what I need to..
I’m still trying to figure out turner pro..I don’t have it yet but doing a lot of reading and don’t understand all the symbols are with the $B or whatever $ that is....Thanks

[myburb]

The apu doesn't have to be used emulating. I just data log with mine, decide what I need to change and burn a chip with the apu.

[myburb]

In ref to tuner pro and the process, it is a litte steep on the learning curve at first. Then it is kind of "bingo" and it all starts to fall in place. With the $, they are the mask which is relevant to your vehicle. In your case it will be $OE or $OD depending on what transmission you have.

I went cheaper (my nature) bought the following from Moates;

while we are passing info to get you going, here is a pigtail extension I made so I could mount the pcm under the front seat but leaving the truck wiring intact.
