1995 lt1 M6 tuning

EEhack and Tunercat are 2 completely different programs that do different things. Tunercat lets you adjust parameters and EEhack lets you scan and log the operation. I think you meant Tunercat vs Tunerpro, which both work similar. You need one of them to do any actual tuning.

The cable can be made with a FT232RL based USB to serial adapter. I bought a few JY-MCU adapters that I've been using. I also added a resistor and diode. I'm trying to recall this quickly, but I'm pretty sure it's a 1K resistor from the TX to the ALDL port data line and a signal diode like a 1N914 from RX to the ALDL port data line with the band towards the RX pin. It's worked well for me, but others have reported issues. Others have also reported counterfeit IC's that could be causing issues.

I don’t mind spending $55-80 for a cable. As I understand it tunerpro is free with voluntary donation, and I would need winflash to actually flash the pcm. I had not heard of eehack prior to this forum, so I don’t know much about it. Would any wideband kit work for these tuners as far as logging? I was looking at the aem kit with bosch 4.9 sensor, it has a 5v serial output on it. I was raised around double pumpers and big blocks so this is new to me.

EEhack will flash, so you can use it to do all the PCM connected work. You need Tunercat or Tunerpro to make tuning adjustments. You could use Tunercat to flash too, but it won't scan or log.

I did confuse Tunercat with Winflash earlier. It's been that long since I used either. I would not recommend Tunercat for editing your bin as it's definition file is somewhat outdated and missing a lot of parameters that are available with one of the many EEX files floating around here. Winflash is also unnecessary.

As far as a cable what I used was this. Unfortunately it's currently out of stock everywhere, but it already has the necessary buffer circuitry. All one has to do is solder RX+TX together and wire that to pin 9 of the aldl, and then connect ground to aldl pin 5.

Excuse me for my lack of knowledge but a tunerCat/tunerpro aldl cable still requires soldering? I was under the impression they were out of the box hookups

Probably not, but paying $55-80 for something you can make for $30 is against my "religion". Also, I had all the parts I needed to make a cable in my parts drawer, which was a factor. So if you're intimidated by soldering buy a ready-made cable. Or, learn a new skill - it's easier than tying your shoes.

Trimalyzer does work for MAF tuning. I haven't messed with it since last fall so all the details are a little fuzzy, but unless you've changed sensors or modified any intake plumbing you shouldn't need to make very drastic changes to the MAF calibration.

I don’t mind soldering, I build rgb guage clusters and headlights. I just stay so busy at work it’s hard to find extra time. Time is more valuable than money to me. Intake is only slightly modified, cold air intake 52mmtb and air foil so I probably won’t have to worry. I researched and found a/c pressure is the best to tie in wideband

Yes, if you buy a complete cable it will work without modifications. If it doesn't, you'd return it for a different one.

I'm not sure where you're looking but http://www.reddevilriver.com has a cable for a decent price.

Will trimalyzer work with maf system now or is it still speed density?
