okay I guess this belongs in here. I'm trying to figure out whether it's easier/better to use a MAF setup or a MAP setup on a TPI. if so what years should I get a wiring harness for?

 

boy this is a hot debate. The top dogs around here will probably tell you that either will achieve the same results as long as you're diligent.

If you want to go the MAF route though - you should look into the newest harness you can get (1989).

 

The $6E MAF stuff is easier to tune but inprecise as its only 8 bits. Using a later $8D will get you better results as there is more then just the 8 bit MAF reading to base the fueling off of, so itll have better resolution. With MAF the fueling gets kinda chunky around idle if your using one of the older thirdgen systems.

Edit: Didnt see that you have a 383. That will quickly overrun the stock MAF. Itll pull more air then the MAF can see. Its possible to tune around it, but this isnt the best solution IMO. Theres a workaround for the $8D to allow it to work properly on large engines with large injectors. Something which doesnt really exist for the MAF ecms.

 

I like both and would take either but I'd want to try both out before going to one or the other .
MAF is generally easier but not always. The $6E can hate you if you do enough changes to the engine. The $8D (MAP) tends to run smoother but takes a little more time tweaking the VE table. I prefer the MAP vs RPM for SA and that's why with 3rd gen's I drift to the $8D. If you take latest being greatest philosophy then the $8D was the last code in a 3rd gen...

 

yeah this is going to be well. no where near stock. just appear that way hehe. but I've been told MAP is the easier way to go about it all

 

The toughest part I have found with a MAF system, is tuning the MAF Scalar tables. But once done, I have found the engine can be further modified (and quite significantly) and the only thing that required any further tuning was the PE Fueling to add extra fuel as the MAF was maxed at fairly low rpms.

Having worked on both, I find MAF easier for closed loop and MAP easier for open loop.

 

FWIW, I'm using the 6E MAF on my 395 cu.in. stroker motor. I used the ARAP bin as a starting point. The engine is running pretty good right now. Most details on motor is in the sig.
