looking for some opinions on my build doing a 88 with speed density and dont wanna do maf conversion looking for the best HCI swap what kind of heads cam and intake gets you a decent package with these options without breaking the bank, thanks

Do you have access to a programming guru? If you stick with stock programming, your parts choices are quite limited.

Budget?

Staying SD without any sort of tuning is going to severely limit you.

Gt40 heads, stock cam and 1.7rrs and explorer/cobra intake with 65mm Tb might be the limit of what you can do without tuning

im sure i can find someone in the city to tune it, what would it take and is it worth it? thanks

 

[88redstang]

is the a9l the only computer that will work with maf conversion also if i installed a9l into my car would i have to re wire the entire car? thanks

 

[88redstang]

would it be worth 500 to buy a tweecer rt? anyone have experience with these?

No, the A9L is not the only option although it's probably the most common. No, you would not need to rewire the whole car for Mass air. There are a few pins at the ECU that need changed as well as the Mass air connector that needs added. You can get the Mass air conversion harness from LMR, it comes with the instructions on how to change your speed density car to Mass air.

Vs convert to Mass Air?

Are you planning an aluminum headed 331 with a turbo? Or a basic Gt40 headed combo? If the later, save yourself some headache and just swap to mass air.

I did it to my ‘88. It’s 7 wires and about 1-2hrs of work.

okay i thought i had to rewire for the ecu but if its just some pins i can do that is there only the two options when switching the ecu to work with mass air its a manual trans, thanks

You need to be a wizard to understand the User Interface. Tuner Studio for Megasquirt is much more user friendly.
No MAF required, no rewiring of factory harness.

I converted my ‘86 5.0 to mass air years ago. The process is pretty simple, but you have to move several wires to new positions in the ECU connector. There’s a tool to remove the connector pins. I’d do the conversion first thing.
