Tuning limitations of the SFI 3.4 ironhead

[ForcedFirebird]

you are refering to the 94-95 LT1 right? then how the hell can it be flashed through the ALDL port? does it have a flash programmer built into a daughterboard or what?

......i hate when i don't have anything to play with in person.......

So in reality, I could be swapping the 93-95 f-bodies to the LT1 setup (has 4 connectors), but I am not totally sure without a test subject.

i need to see the inside of a 94-95 LT1 PCM, NOW!

BTW: if you can figure out how to deal with the optispark, go for it.

[tkoforpresident]

it would be so much easier to have an lt1.....

[robertisaar]

true, but this isn't the LT1 forum now is it?

EDIT: Holy crap!!! I just clicked that link and didn't realize they are charging that much!!! I can build you a custom harness for about $350-$400.

You know I've been asking people sence I joined this site and nobody is willing or able when it come to ponying up to the table and put "MY" money where "THERE" mouth is...
If you or anybody can really set me up with a usable harness (w/instruction) and progamable ECM. With the smog sh*t removed, and ready to be bolted to a vintage car and ready to go.
3.4 iron head, t5 Rwd, vintage car with minimal elc...
P.M. me and we'll work out the details and $$$

But until then that brit guys deal and price looks pretty good for me!

Forced is the real deal

[ForcedFirebird]

LOL, thanks Dave. You have done some really nice stuff yourself

Are you putting a complete 3.4 iron head in your car, or are you making a hybrid? Where are you planning on putting the ECM?

I don't know about instructions, but I label everything...

Here's and adapter if you use the complete 3.4 harness and just want to tune it...

Either of those can be used to get you running. You will be responsible for tuning after (although I can include a simple 3.4 tune), but if you look at TKOforPresident's thread, you will see it's really not that difficult to learn the tuning on your own.

I prefer to use emails mainly because the PM boxes on the forums fill up so fast. John at 60inclusive.com.

Wow impressive..
I'm not running a hybrid, Ironhead 3.4..
Is that an OBD1 , 1.5,or 2...
I ask for instructions cause i know nothing of efi... lol
but if it's easy and labled i should be fine... ECM will most likely be under the dash on the right side or the glove box...
that 2nd thread is that the hookup for a scanner/flash?

John... All that work looks just incredible... And as for the labor involved in wrapping the harnesses so carefully, too. But I was wondering though... Why not choose to use Electrical Shrink Wrap in lieu of something so very labor intensive after you have the wiring harnesses laid out on your loom and checked out on your LED Confirmation Panel? This stuff looks like it would do the trick for you much easier...and if you knew the dimensions of the vehicle engine compartment layout, you could almost pre-shape each of the harnesses while using the heat gun to apply the tubing. I don't know how expensive or durable seven rolls of friction tape would be...but it would seem to be the most labor difficult part of the job... I used a lot of shrink wrap in the USCG as an Aviation Machinist Mate...and it really was some durable stuff. Ace Hardware online has a kit with 8' sections and includes a Heat Gun to boot for under $12.00. You can view the data here...

If an adjustment needs to be made it's much easier to unwrap tape.. I'd personally use a high quality wire loom though.

[60dgrzbelow0]

Understood... and makes perfect sense if testing shows a bad wire somewhere... and as for looms...I agree... Something like this might be just right:

I do use split loom, then wrap it.

Ahhhhhhh.... of course! (Take the Pebble from my hand...Grasshopper...) I should have known that you were too clever to sit on the floor in the middle of what could become a "Medusa"-like Cluster-F*ck of tangled wires when trying to control them all and wrapping of that up so neatly...

See?...THIS is how we all learn from you... Master Po!
