Merkur harness works with which engines?
OhSix9:
You are already on the path to going a little further than what the pe can do stock anyways. the repin data that was supplied above is only if you choose to go with an 87/88 L series computer. it gives you a couple extra sensors such as act which gives post IC air temps vs IAT and a faster processor. the harness you have will be plug and play on any P series computer PE , PK1 etc. now the good news is that either of these solutions can be custom tuned with a j3 port adapter and a programmer from moates for under 60 bucks. that costs less than what most will charge for a true PE or LA box where they will give away small vam or autobox ecu's for nothing. take any p series flash it with a pe bin and its big vam, injector and intercooler ready. same with the auto l series. throw on the flash and they are manual LA ecu's the nice part is you can custom tune ignition maps and fuel delivery for all rpm and conditions. Also the vam really runs out of steam around 325cfm. using the above solution, a big maf off a 4.6l car with a known curve add some clicks of a mouse you can take the system to mass air ditching the junk vam. run injectors upto 75Lb/hr, play with rev limits bla bla bla. what most people fail to realize is tat the eecIV is a brilliant piece of engine control with more power under the hood than most of these aftermarket systems can offer if you take a little while to really grasp what it can do. add some data logging with a wideband and 3 channels and there is nothing any standalone system costing hundreds more could do better. the qaurterhorse mentioned above is an upgrade to the j3 adapter but doesn't datalog well on the p series and does not support wide band o2 anyways so i don't use it.
moates.net makes the most sense. anyway you cut it. no need to search out specific computers and gain flex all at a cheaper price
For what you are thinking. knife edge the lower, take the upper and gut n rotate it or build one custom starting from a waterjet copy of the upper flange n make the right size for your chosen throttle body. just be sure to pick one with an integrated iac motor. get some 56lb injectors from a cfi HO tbird and bobs yer uncle. proceed to blow on it as hard as you can .

UMMMM WoW!!! OhSix9
Pinto 5.0 when you get that figured out... Share with me please ;D
I have the 85 TC 5 speed in my 79 wagon.. Bigger plans for it later down the road.
I need to get my AK Miller 2.0 installed on the 23 T. first.

I followed him on most of it. I've been reading everything I can find lately to educate myself but my EFI knowledge is still limited. I'm not ready for laptop tuning & setting up custom maps just yet. At some point I will be but for now I need to keep it fairly simple so I don't abandon the project half way through. After I'm comfortable that my knowledge is significant to dive in deeper I may try a stroker, C4 with trans. brake & stand alone ECU. I'm simply not skilled enough for that kind of build.
What I have in my garage so far is a 20K mile '79 turbo engine, T-5 trans, D5 bellhousing, new Turbo Coupe clutch/flywheel & merkur wire harness.
What I may purchase: I found an LA3 ECU for under 100 bucks. I can get the big VAM from Advance Auto for about 75 bucks with my discount, I'm looking at the Merkur center dump header, ported T-bird intake with turned plenum & 35 pound injectors. I priced out most of the sensors at Advance & that should set me back 300 or so but they will all be new parts. Turbo will depend on how much of my wish list ends up in my garage & the intercooler will be sized for the turbo.
I just need to know this stuff will work together & fire up in my garage without needing a group of experts on call. If that's a pipe dream then I need to know now so I can just locate a worn out 87-88 Turbo Coupe & strip all the stock parts & bolt them all on my engine & wire it in with the Merkur harness to save myself the headaches.

I think the only weekness would be the 79 turbo engine head (Wasn't that like the first setup from Ford with the 2.3 turbo)?... Most people that I have read about use the later model for the mods your seeking.
Although I'm still way behind you in regards to the knowledge. I just go by what I have read and seen.
If you have the 87-88 TC parts available get them for sure!!!

Yeah, the engine came out of a '79 Mustang Pace Car & had a draw through system on it. The engine has the forged pistons & the oil drainback hole for the turbo. The head has the factory turbo cam & it's an oval port. As far as I know the head should be fine.
