[stupidboy]

thanks man, I'll be sure and do that, thats exactly what I'm trying to avoid, buying and rebuying.

In my favorites tab , I created a file just for the EFI links (and tranny stuff , dana 60 stuff , etc).
Here are a few:

I referenced this page alot , the BD article , which is in reprint the past several issues by the way.

If you havent bought anything yet, go to you tube and seach powerjection 3. Watch the install on the mustang. Neat system and reasonable price of sorts. It was what I was going to go with but I wanted a roller motor and serp belt sys so I bought a complete car and am going to do the RJM wire harness and use the factory EFI... JMO

Good post, look thru some of the pics to see the fit to the compartment. My lesson learned is the c4 isn't much on the freeway. The trans option with an of is a nice option.if you like the pics of my 5.0 HO, all 91 mustang GT including the AOD, I'll offer my parts list and experiences. One concern is $$ and time, you won't find all the answers in one easy location

Looked at your gallery, very nice!

Lil info I decided to try and go ahead with my current flat tap cam to avoid the 700$ worth of roller stuff to make it a roller again. Will post results when its done. btw this a 302 firing order and the biggest cam I can run with a C4 and stock converter.

AGREED! Very nice work youve done AAA+

 

[DirtDonk]

You plannin' to run it as-is, or are you going to have the ECU tuned?

Let me ask this. I'm getting ready to buy the rest of my efi stuff for my swap and I want to make sure I get the right parts. Its been a while since we talked about this so I've been searching this stuff on here again and can't seem to find the answer, so I need refreshed. I am using a 351 which has the HO firing order. What computer is the best to use? Does it need to be from a 5 liter HO? I thought I read somewhere where the computer will run both firing orders but will have rough idle and maybe other issues. I don't want these issues. What computer do I need to run my 351 firing order without issues for MAF? For some reason I have it in my mind that the computer will be firing the wrong injectors or is this wrong?

 

[RustyShackelfor]

what about a 95 f150 5sp with 5.8 computer? Its before the OBDII and had mass air.

Any of the mustang '88-'93 ECU's will be fine with matching parts (MAF, injectors). http://rjminjectiontech.com/pages/50-compatibility-list

351W cam firing order is the same as the 5.0 HO cam firing order. Even if you use an older 302 cam with the 15426378 order it would be fine.

 

[stupidboy]

So then is that system, bank fire or sequential fire?

 

[Viperwolf1]

Mustang is sequential.

 

[stupidboy]

Are all 88-93 mustangs HO's? if not would the wrong injectors fire at the wrong time if I was to not have an HO ecu and harness? I think I found the answer, But out of the computers listed on the ford fuel inj. site, are they all HO computers? Just trying to have a better understanding, sorry.

All these ECUs are mustang: A9L / A3M / A3M1 / S0Z / D3D1 / A9S / 8LD / A9P / C3W / C3W1 / A9M / A9T / 8LF / 8LG

All have the sequential HO, 13726548 firing order. Same as your 351W.

 

[stupidboy]

Thanks vw, do you have any laying around, hard to find any in my neck of the woods.

 

[Viperwolf1]

I only have one, and it's in use.

 

[NYLES]

get one from napa

 

[stupidboy]

get one from napa

Do I need a core? I called and checked, 121.50 plus 117.00 core plus tax. I have no core.
